Bristol is the cheapest city and Paul can drop from his plans to stay under budget.
To determine which city Paul can drop and still stay under budget, we need to find the total cost of visiting all four cities and compare it to Paul's budget of £300.
We do not have information about the cost of sightseeing in each city, so we will assume that the cost is the same for each city. In that case, the cost of visiting all four cities is:
Cost of visiting all cities = Cost of visiting one city x 4
Let's call the cost of visiting one city "x". Then:
Cost of visiting all cities = x * 4
To stay under budget, the cost of visiting all cities must be less than or equal to £300. So we can write the following inequality:
Simplifying this inequality, we get:
x ≤ £75

The answer is (c) Bristol, as it has the highest cost among the remaining cities and dropping it would leave Paul with 224 pounds, which is still within his budget.
What is budget?A budget is whenever one plans on how to spend an estimated income. All the income should be considered as well as all the expenses. In other words, it is an expending plan.
The total cost of visiting all cities is:
76 + 66 + 91 + 60 + 72 = 365
To stay under budget, Paul must drop at least one city. To determine the cheapest city to drop, we can calculate the cost of the trip to each city if visited individually and compare it to the remaining budget:
- Bristol: 76 pounds
Remaining budget: 300 - 76 = 224 pounds
- Leicester: 66 pounds
Remaining budget: 300 - 66 = 234 pounds
- Glasgow: 91 pounds
Remaining budget: 300 - 91 = 209 pounds
- Leeds: 60 pounds
Remaining budget: 300 - 60 = 240 pounds
- Belfast: 72 pounds
Remaining budget: 300 - 72 = 228 pounds
The city that Paul can drop while staying under budget is the one with the lowest cost.
Therefore, the answer is (c) Bristol, as it has the highest cost among the remaining cities and dropping it would leave Paul with 224 pounds, which is still within his budget.

El 91 no es un número primo porque tiene más divisores que el 1 y el 91 verdadero o falso
The statement''El 91 no es un número primo porque tiene más divisores que el 1 y el 91'' is true because 91 is not a prime number.
A prime number is a positive integer that has only two divisors, 1 and itself. To check if 91 is a prime number, we need to find its divisors. We can start by dividing 91 by 2, but we find that 2 is not a divisor of 91. Next, we can try dividing it by 3, and we get 30 with a remainder of 1. This means that 3 is not a divisor of 91 either.
We continue dividing by 4, 5, 6, and so on until we reach 13, which gives us 7 as a quotient and 0 as a remainder. Therefore, the divisors of 91 are 1, 7, 13, and 91, which means that 91 is not a prime number because it has more than two divisors. Hence, the statement is true.
91 ÷ 2 = 45 r 1
91 ÷ 3 = 30 r 1
91 ÷ 4 = 22 r 3
91 ÷ 5 = 18 r 1
91 ÷ 6 = 15 r 1
91 ÷ 7 = 13 r 0
Since 91 has more than two divisors, it is not a prime number.

) Nadia buys 4 1/5 pounds of plums. Nadia used a 55 cent coupon off her entire purchase. Her total after the coupon was $3. 23. If c represents the cost per pound for the plums, create and solve an equation to determine the cost per pound for the plums
If c represents the cost per pound for the plums, the cost per pound for the plums is $0.90.
First, we need to determine the total cost of the plums before the coupon was applied.
4 1/5 pounds can be written as a mixed number:
4 1/5 = 21/5
So, the total cost of the plums without the coupon can be found by multiplying the cost per pound (c) by 21/5:
Total cost = c * 21/5
Now we can create an equation to represent the total cost after the coupon was applied:
Total cost - coupon = $3.23
Substituting the expression for total cost:
c * 21/5 - 0.55 = 3.23
To solve for c, we can start by adding 0.55 to both sides:
c * 21/5 = 3.78
Then, we can isolate c by multiplying both sides by the reciprocal of 21/5:
c = 3.78 / (21/5)
c = 0.90
Therefore, the cost per pound for the plums is $0.90.

12. 3% for Federal Income Tax, 6. 3% for Social Security, and 1. 45%
for Medicare. What steps did I take to find Jesus' net bi-weekly
pay? (Show your work)
Jesus' net bi-weekly pay is $856.69 after paying his taxes and deductions.
To find Jesus' net bi-weekly pay, I followed these steps:
Calculate Jesus' commission: Jesus sold $16,200 of computer equipment, so his commission is 5.5% of $16,200, which is $891.
Calculate Jesus' gross bi-weekly pay: Jesus receives a bi-weekly salary of $300 plus his commission of $891, so his gross bi-weekly pay is $1,191.
Calculate Jesus' deductions: Jesus pays 8% for State Income Tax, 12.3% for Federal Income Tax, 6.3% for Social Security, and 1.45% for Medicare. To calculate the deductions, I multiplied his gross bi-weekly pay by each percentage rate:
State Income Tax: 8% of $1,191 = $95.28
Federal Income Tax: 12.3% of $1,191 = $146.67
Social Security: 6.3% of $1,191 = $75.09
Medicare: 1.45% of $1,191 = $17.27
Subtract the deductions from the gross bi-weekly pay: To find Jesus' net bi-weekly pay, I subtracted the total deductions of $334.31 from his gross bi-weekly pay of $1,191:
Net bi-weekly pay = $1,191 - $334.31 = $856.69
Therefore, Jesus' net bi-weekly pay is $856.69 after paying his taxes and deductions.

Steph Curry posts a video of a puppy playing the piano and shares it with 4 of his friends. The video goes viral and the number of shares increases by a factor of 10 every minute.
a. Write an equation to model this situation.
b. What is the average rate of change for the number of shares from 2 minutes to 4 minutes?
An equation to model this situation will be S(t) = 4 * 10^(t). The average rate of change for the number of shares from 2 minutes to 4 minutes is approximately 19,800 shares per minute.
a. Let S(t) be the number of shares of the video at time t in minutes after Steph Curry shared it with his friends. The initial number of shares is 4 (the 4 friends he shared it with), and the number of shares increases by a factor of 10 every minute. Therefore, we can model this situation with the exponential function:
S(t) = 4 * 10^(t)
b. The average rate of change for the number of shares from 2 minutes to 4 minutes can be calculated by finding the slope of the line connecting the points (2, S(2)) and (4, S(4)) on the graph of S(t). Using the equation S(t) = 4 * 10^(t), we have:
S(2) = 4 * 10^(2) = 400
S(4) = 4 * 10^(4) = 40,000
The slope of the line connecting these two points is:
(S(4) - S(2)) / (4 - 2) = (40,000 - 400) / 2 = 19,800
Therefore, the average rate of change for the number of shares from 2 minutes to 4 minutes is approximately 19,800 shares per minute.

Number of triangles formed is 4 ⇒ regular hexagonInterior angle sum is 1,440 ⇒ regular decagonInterior angle sum is 1,800 ⇒ regular dodecagonNumber of triangles formed is 6 ⇒ regular octagon.How to determine the number of triangles and interior angle sum?In Mathematics and Geometry, the sum of the interior angles of both a regular and irregular polygon can be calculated by using this formula:
Sum of interior angles = 180 × (n - 2)
1,440 = 180 × (n - 2)
1,440 = 180n - 360
180n = 1,440 + 360
n = 1,800/180
n = 10 (decagon).
Sum of interior angles = 180 × (n - 2)
1,800 = 180 × (n - 2)

The two points we have are when x = 3 and 6.
the points are (3, 120) and (6, 0), as we can see.
plugging into the slope formula:
S = [tex]\frac{120-0 }{ 3-6}[/tex]

An 8-inch-by-4-inch hole is cut from a
rectangular metal plate, leaving borders
of equal width x on all four sides. The
area of the metal that remains is 32 in².
The equation (8 + 2x)(4+2x) - 32 = 32
models the area of the plate. What is the
value of x, the frame width?
Answer:
2 inches
Step-by-step explanation:
The area of the metal plate can be calculated by subtracting the area of the hole from the area of the original plate. The area of the original plate is:
8 inches x 4 inches = 32 square inches
The area of the hole is:
8 inches x 4 inches = 32 square inches
So the area of the metal that remains is:
32 square inches - 32 square inches = 0 square inches
According to the equation given, we know that:
(8 + 2x)(4 + 2x) - 32 = 32
Expanding this equation we get:
32 + 16x + 8x + 4x^2 - 32 = 32
Simplifying and rearranging we get:
4x^2 + 24x - 32 = 0
Dividing both sides by 4 we get:
x^2 + 6x - 8 = 0
We can solve this quadratic equation by factoring:
(x + 4)(x - 2) = 0
So x = -4 or x = 2. Since the width of the frame cannot be negative, the only valid solution is x = 2.
Therefore, the frame width is 2 inches.

write out all the work used to determine the answer to the question.
Each of the three sisters owes $75 to cover the cost of hiring the karaoke deejay for Taylor's graduation party.
To determine how much each sister owes, we need to first calculate the total cost of the party and then divide that cost by three, since there are three sisters splitting the cost.
1. Tent rental: $45
2. Microphone system: $60
3. Deejay cost: $30/hour × 4 hours = $120
Now, we'll add these costs together to find the total cost:
Total cost = $45 (tent) + $60 (microphone) + $120 (deejay) = $225
Finally, we'll divide the total cost by the number of sisters (3) to find out how much each sister owes:
Amount owed per sister = $225 (total cost) ÷ 3 (sisters) = $75
So, each sister owes $75 for the karaoke deejay at Taylor's graduation party.

solve quadratic equation 6x²-11x-35= 0 pls needed urgently
Answer:
Step-by-step explanation:To solve the quadratic equation 6x²-11x-35= 0, we can use the quadratic formula:
x = (-b ± sqrt(b² - 4ac)) / 2a
where a, b, and c are the coefficients of the quadratic equation.
In this case, we have:
a = 6
b = -11
c = -35
Substituting these values into the quadratic formula, we get:
x = (-(-11) ± sqrt((-11)² - 4(6)(-35))) / 2(6)
Simplifying this expression:
x = (11 ± sqrt(121 + 840)) / 12
x = (11 ± sqrt(961)) / 12
x = (11 ± 31) / 12
So, we have two solutions:
x = (11 + 31) / 12 = 3
and
x = (11 - 31) / 12 = -5/2
Therefore, the solutions to the equation 6x²-11x-35= 0 are x = 3 and x = -5/2.
Find the smallest number of terms of the series ∑ n = 1 (-1)^n+1/2^n you need to be certain that the partial sum Sn is within 1/100 of the sum.n=2 n=4 n=6 n=8 n=7
We need at least 7 terms of the series to be certain that the partial sum Sn is within 1/100 of the sum.
We want to find the smallest value of n such that the absolute value of the difference between the sum of the first n terms and the sum of the entire series is less than 1/100.
The sum of the first n terms of the series is given by:
Sn = ∑_(k=1[tex])^n[/tex] (-1[tex])^(k+1)[/tex]/[tex]2^k[/tex]
We can write the sum of the entire series as:
S = ∑_(k=[tex]1)^∞[/tex] (-1[tex])^(k+1)[/tex]/[tex]2^k[/tex]
The absolute value of the difference between the sum of the first n terms and the sum of the entire series is:
|S - Sn| = |∑_(k=n+1[tex])^∞[/tex] [tex](-1)^(k+1)/2^k|[/tex]
We want to find the smallest value of n such that |S - Sn| < 1/100.
Let's start by evaluating the sum of the series:
S = ∑_(k=1) (-1[tex])^(k+1)[/tex]/[tex]2^k[/tex] = 1/2 - 1/4 + 1/8 - 1/16 + ...
This is a geometric series with first term a = 1/2 and common ratio r = -1/2. The sum of the series is:
S = a/(1-r) = (1/2)/(1+1/2) = 1/3
Now we can write:
|S - Sn| = |∑_(k=n+1[tex])^∞[/tex] (-1[tex])^(k+1)[/tex]/[tex]2^k|[/tex] <= 1/[tex]2^(n+1)[/tex]
The last inequality is true because the terms of the series are decreasing in absolute value, and we are summing an infinite number of terms.
Therefore, we need to find the smallest value of n such that 1/2^(n+1) < 1/100. This gives:
n+1 > log2(100)
n > log2(100) - 1
n > 6.64
The smallest integer value of n that satisfies this inequality is n = 7.
Therefore, we need at least 7 terms of the series to be certain that the partial sum Sn is within 1/100 of the sum.

Two different box-filling machines are used to fill cerealboxes on the assembly line. The critical measurement influenced bythese machines is the weight of the product in the machines. Engineers are quite certain that the variance of the weight ofproduct is σ^2=1 ounce. Experiments are conducted using bothmachines with sample sizes of 36 each. The sample averages formachine A and B are xA=4. 5 ounces and xB =4. 7 ounces. Engineers seemed surprisedthat the two sample averages for the filling machines were sodifferent.
a. Use the central limit theorem to determine
P(XB- XA >= 0. 2)
under the condition that μA=μB
b. Do the aforementioned experiments seem to, in any way,strongly support a conjecture that the two population means for thetwo machines are different?
a. By central limit theorem, P(XB- XA >= 0. 2) is approximately 0.0228 under the condition that μA=μB.
b. Yes, we can conclude that the observed difference in sample means does provide evidence that the two population means for the two machines are different.
a. Using the central limit theorem, we know that the sampling distribution of the difference in means (XB - XA) is approximately normal with mean (μB - μA) and standard deviation (σ/√n), where σ is the population standard deviation (σ=1 ounce) and n is the sample size (n=36 for both machines).
So, P(XB - XA >= 0.2) can be calculated by standardizing the difference in means:
Z = (XB - XA - (μB - μA)) / (σ/√n)
Z = (4.7 - 4.5 - 0) / (1/√36)
Z = 2
Looking up the probability of Z being greater than or equal to 2 in a standard normal distribution table, we find P(Z >= 2) = 0.0228.
Therefore, P(XB - XA >= 0.2) is approximately 0.0228 under the condition that μA=μB.
b. The difference in sample means (XB - XA = 0.2) is relatively small compared to the population standard deviation (σ=1 ounce). However, the calculated probability in part a (0.0228) suggests that the observed difference in sample means is statistically significant at a significance level of 0.05 (since P(XB - XA >= 0.2) < 0.05).
Therefore, we can conclude that the observed difference in sample means does provide evidence that the two population means for the two machines are different. However, further testing or analysis may be necessary to confirm this conclusion.

Vanessa's team played 8 games of basketball. During those 8 games her team's score was: 68, 76, 63, 58, 64, 75, 78 and 78.
What is the mean absolute deviation?
Please help!! Please answer it correctly too!!!! Whoever gets it correct gets brainliest!! and then I will give them 154 points!!!! please!!
The mean absolute deviation is 6.25.
To find the mean absolute deviation (MAD), we first need to find the mean of the scores:
Mean = (68 + 76 + 63 + 58 + 64 + 75 + 78 + 78) / 8 = 69.5
Next, we need to find the absolute deviation of each score from the mean. The absolute deviation is the absolute value of the difference between the score and the mean.
For example, the absolute deviation of the first score (68) is:
|68 - 69.5| = 1.5
We can calculate the absolute deviation for each score:
|68 - 69.5| = 1.5
|76 - 69.5| = 6.5
|63 - 69.5| = 6.5
|58 - 69.5| = 11.5
|64 - 69.5| = 5.5
|75 - 69.5| = 5.5
|78 - 69.5| = 8.5
|78 - 69.5| = 8.5
To find the MAD, we take the average of the absolute deviations:
MAD = (1.5 + 6.5 + 6.5 + 11.5 + 5.5 + 5.5 + 8.5 + 8.5) / 8 = 6.25
Therefore, the mean absolute deviation is 6.25.

Clara's class is preparing for a field trip. Her teacher purchased bottled water for the trip and asked Clara to stock a cooler with 2 bottles for every student who is going. 5 of the students didn't turn in permission slips and aren't going on the trip. So, Clara stocks the cooler with 38 bottles of water.
Which equation can you use to find the total number of students, n, in Clara's class?
The equation that can be used to find the total number of students would be n = 19 + 5.
How to find the equation ?It is acknowledged that Clara provided 2 bottles per each pupil joining her on the excursion. Denote, by using ‘x’, the quantity of learners present; we can then inscribe the succeeding formula:
2x = 38
By resolving this mathematical principal, the total number of students attending the event is revealed.
x = 38 / 2
x = 19
Currently, 19 individuals are confirmed to embark upon the outing, due to five individuals failing to furnish required consent forms and will be absent. Subsequently, we may deduce the quantity of pupils (designated as ‘n’) in Clara’s class:
n = 19 (students going on the trip ) + 5 ( students not going )
n = 19 + 5

Find an equation of the plane that passes through the given point and is perpendicular to the given vector or line.
Point (0, 9, 0) Perpendicular to
n = -2i ÷ 4k
To find the equation of the plane that passes through the point (0, 9, 0) and is perpendicular to the vector n = -2i ÷ 4k, we first need to find the normal vector of the plane.
Since the plane is perpendicular to the given vector, the normal vector will be parallel to it. So, we can take the given vector and multiply it by -1 to get a vector in the opposite direction, which will be normal to the plane.
n = -2i ÷ 4k = -1/2i ÷ k
Multiplying by -1 gives us:
n = 1/2i ÷ k
Now we can use the point-normal form of the equation of a plane:
r · n = d
where r is the position vector of any point on the plane, n is the normal vector, and d is the distance of the plane from the origin (since the normal vector is normalized, d will be the signed distance of the plane from the origin).
Substituting the given point (0, 9, 0) and the normal vector n = 1/2i ÷ k into the equation, we get:
(0, 9, 0) · (1/2i ÷ k) = d
0 + 9(1/2) + 0 = d
d = 4.5
So the equation of the plane is:
x/2 + z/2 = 4.5
or, multiplying by 2 to eliminate fractions:
x + z = 9

new purchases of $1,697. 08, and a payment of $4,900. 50. What is her new balance?
a. $3,454. 99
c. $3,566. 44
b. $3,282. 35
d. $3,112. 78
Sally Rose's new balance is $3,282.35, and option (b) is the correct answer.
Sally Rose's charge account statement contains information about her previous balance, finance charge, new purchases, and payment. To determine her new balance, we need to take the previous balance, add the finance charge and new purchases, and then subtract the payment.
Starting with the previous balance of $6,472.82, we add the finance charge of $12.95 and new purchases of $1,697.08 to get a total of:
$6,472.82 + $12.95 + $1,697.08 = $8,182.85
Next, we subtract the payment of $4,900.50 to get the new balance:
$8,182.85 - $4,900.50 = $3,282.35

a florida citrus grower estimates that if 60 orange trees are planted, the average yield per tree will be 400 oranges. The average yield will decrease by 4 oranges per tree for each additional tree planted on the same acreage. Express the grower's total yield as a function of the number of additional trees planted, draw the graph and estimate the total number of trees the grower should plant to maximize yield.
Answer: 80 trees
Step-by-step explanation:
YIELD = (NUMBER OF TREES)*(NUMBER OF ORANGES PER TREE)
Let's assume NUMBER OF TREES = 60 + x, where x is the number of additional trees above 60
The NUMBER OF ORANGES PER TREE will = (400-4x). Hence:
YIELD = (60+x)*(400-4x) = 24000-240x+400x-4x2 = -4x2 + 160x + 24,000
To find the maximum YIELD, take the derivative of YIELD wrt x, set it to zero, and solve for x:
d(YIELD)/dx = -8x + 160
0 = -8x +160
8x = 160
x = 20
The grower should grow 60 + 20 = 80 trees to maximize yield.
Answer: 80 trees

Step-by-step explanation:
If there are 180 degrees in a triangle total and in this problem we know that one angle is 49 and the other is 39, we can assume that subtracting 39 and 49 from 180 will find x. In this case, x will be 92.
Para el periódico mural, los alumnos decidieron representar un pino por medio de un triángulo que tiene una superficie de 1. 5m si la base mide 1. 5 m ¿cuanto mide la altura? 
The height of the triangle is 2 meters.
How tall is triangle?Para encontrar la altura del triángulo, podemos utilizar la fórmula para calcular el área de un triángulo:
Área = (base x altura) / 2
Sabemos que el área es de 1.5 m² y que la base mide 1.5 m, por lo que podemos despejar la altura de la siguiente manera:
1.5 m² = (1.5 m x altura) / 2
Multiplicando ambos lados por 2:
3 m² = 1.5 m x altura
Despejando la altura:
altura = 3 m² / 1.5 m
altura = 2 m
Por lo tanto, la altura del triángulo que representa al pino en el periódico mural es de 2 metros.
