Step-by-step explanation:
Ok so let's make this problem a bit simpler by splitting it up.
Tim paints a room in 6 hours.
So, we can also say that she paints 1/6 of that room in 1 hour
Bella paints it in 4 hours
So, we can also say that she paints 1/4 of that room in 1 hour
Now, lets see what we have:
Bella: 1/4 every hour
Tim: 1/6 every hour
The problem states that they are working together, so we need to add the values we have:
1/4 + 1/6
We cannot just add them, we must make them have the same common denominator.
LCD is 12, you can find that by just doing the times tables for 4 and 6 and seeing what number they match on first.
3/12 + 2/12 = 5/12
So, tim and bella working together paint 5/12 of a room in 1 hour.
They paint 5/12 of a room in 60 minutes
They paint 1/12 of the room in 12 minutes(divide both values by 5)
So if they paint 1/12 of the room in 12 minutes, we can multiply both values by 12 to get our answer.
They paint the full room in 144 minutes(12*12).
144 minutes is 2 hours and 24 minutes
Resolver la siguiente in ecuación |2x-3|< 3+x-x^2
Answer:
Step-by-step explanation:
To solve the equation, we'll need to consider two cases:
Case 1: 2x - 3 is positive or zero
If 2x - 3 is positive or zero, then |2x - 3| = 2x - 3, and the inequality becomes:
2x - 3 < 3 + x - x^2
Rearranging and simplifying:
x^2 - x - 6 < 0
Factoring:
(x - 3)(x + 2) < 0
The solutions to this inequality are:
-2 < x < 3
However, we still need to check that 2x - 3 is indeed positive or zero for this range of x. We can see that this is true for x in the range (-2, 3), so this is a valid solution.
Case 2: 2x - 3 is negative
If 2x - 3 is negative, then |2x - 3| = -(2x - 3), and the inequality becomes:
-(2x - 3) < 3 + x - x^2
Rearranging and simplifying:
x^2 - 3x - 6 < 0
Factoring:
(x - 3)(x + 2) > 0
The solutions to this inequality are:
x < -2 or x > 3
However, we still need to check that 2x - 3 is indeed negative for this range of x. We can see that this is true for x < -2, so this is a valid solution.
Putting these two cases together, we get the solution:
x < -2 or -2 < x < 3

REI sells a four person nylon tent shaped like a square pyramid. The slant height of the triangle is 6.5 feet and each side of the square base measures 8 feet. What is the minimum square footage of nylon used to make the tent?
The minimum square footage of nylon used to make the tent is 168 square feet.
How to determine the minimum square footage of nylon used to make the tent?To find the minimum square footage of nylon used to make the tent, we need to calculate the area of each of the four triangular faces and the area of the square base, and then add them up.
The area of each triangular face is given by the formula:
A = 1/2 × base × height
where the base is the side length of the square base (8 feet), and the height is the slant height of the pyramid (6.5 feet).
A = 1/2 × 8 × 6.5
A = 26
So each of the four triangular faces has an area of 26 square feet.
The area of the square base is given by the formula:
A = [tex]side length^{2}[/tex]
A = [tex]8^{2}[/tex]
A = 64
So the square base has an area of 64 square feet.
To find the minimum square footage of nylon used to make the tent, we can add up the areas of the four triangular faces and the square base:
4 × 26 + 64 = 104 + 64 = 168
Therefore, the minimum square footage of nylon used to make the tent is 168 square feet.

using known taylor series find the first 4 nonzero terms of thetaylor series for the function f(t)=e^(t)cos(t) about 0
The first four nonzero terms are 1 + t - (t^2)/2 - (t^3)/3 + (t^4)/8
To find the first 4 nonzero terms of the Taylor series for the function f(t) = e^(t)cos(t) about 0,
we can use the known Taylor series for e^(t) and cos(t).
Taylor series:
The Taylor series for e^(t) is:
e^(t) = 1 + t + (t^2)/2! + (t^3)/3! + ...
And the Taylor series for cos(t) is:
cos(t) = 1 - (t^2)/2! + (t^4)/4! - (t^6)/6! + ...
To find the Taylor series for f(t) = e^(t)cos(t), we can multiply these two series together using the distributive property of multiplication. We get:
f(t) = (1 + t + (t^2)/2! + (t^3)/3! + ...) * (1 - (t^2)/2! + (t^4)/4! - (t^6)/6! + ...)
Expanding this out, we get:
f(t) = 1 + t - (t^2)/2 - (t^3)/3 + (t^4)/8 + (t^5)/15 - (t^6)/72 - ...
The first 4 nonzero terms of this series are:
f(t) = 1 + t - (t^2)/2 - (t^3)/3 + (t^4)/8 + ...

Taylor series:
To find the first four nonzero terms of the Taylor series for the function cos(20x²) about 0,
we need to find the first few derivatives of the function, and evaluate them at x = 0.
f(x) = cos(20x²)
f'(x) = -40x * sin(20x²)
f''(x) = -40(40x² * cos(20x²) + 20sin(20x²))
f'''(x) = 40(1600x³ * sin(20x²) + 120x * cos(20x²))

f''(y) = 16 / (1 - 4y)²
f'''(y) = -96 / (1 - 4y)³

Pedro is walking down the longest staircase ever, which contains 4000 steps. She starts from the top and is walking down the staircase at 150 steps a minute. Hal is walking up the staircase, starting at the bottom, at 80 steps a minute. After how many minutes will they meet?
Let's assume that they will meet at point X, which is y steps away from the top and z steps away from the bottom. As Pedro is walking down the staircase, she will cover a distance of y steps, while Hal is walking up the staircase, he will cover a distance of (4000-z) steps.
The time taken by Pedro to cover a distance of y steps is y/150 minutes, while the time taken by Hal to cover a distance of (4000-z) steps is (4000-z)/80 minutes. Since they will meet at the same point X, we can set these two times equal to each other and solve for y and z.
y/150 = (4000-z)/80
Solving this equation, we get y = 1800 and z = 2200. This means that Pedro will have covered 1800 steps in y/150 = 12 minutes and Hal will have covered (4000-2200) = 1800 steps in (4000-2200)/80 = 25 minutes.

Karmen is buying a new car. For the car's exterior, she can choose from three colors-black, gray, or white. For the interior, she can choose between
belge and gray. She can also choose between a manual and an automatic transmission
if Karmen picks a car at random, what is the probability of picking a car that has a black exterior and a belge interior?
What is the probability of picking a car with a belge interior and an automatic transmission?
The probability of Karmen picking a car with a black exterior and a belge interior is
The probability of Karmen picking a car with a belge interior and an automatic transmission is
The probability of Karmen picking a car with a belge interior and an automatic transmission is 1/6
How to find the probability?To find the probability, we need to start by identifying the event or situation for which we want to calculate the probability.
Since Karmen has three choices for the exterior color, two choices for the interior color, and two choices for the transmission, the total number of possible car configurations is:
3 x 2 x 2 = 12
This means there are 12 different cars to choose from.
To find the probability of picking a car that has a black exterior and a belge interior, we need to determine how many cars meet these criteria. There is only one car that has a black exterior and a belge interior, so the probability of picking this car is:
1/12
Therefore, the probability of Karmen picking a car with a black exterior and a belge interior is 1/12.
To find the probability of picking a car with a belge interior and an automatic transmission, we need to determine how many cars meet these criteria. There are two cars that have a belge interior and an automatic transmission, so the probability of picking one of these cars is:
2/12
Simplifying this fraction gives:
1/6
Therefore, the probability of Karmen picking a car with a belge interior and an automatic transmission is 1/6.

Adding 12 apples to a basket initially containing c apples results in a total of 13.50 apples.
How can a real-world situation be represented by the equation 12 + c = 13.50?
The equation 12 + c = 13.50 can represent a real-world situation of purchasing items at a store and calculating the total cost. In this scenario, let's assume that 12 represents the price of a particular item, and c represents the additional cost, such as taxes or fees.
The equation states that when the additional cost is added to the base price of 12, the total cost becomes 13.50. This can occur when there is a sales tax or an additional charge applied to the base price. By solving the equation for c, we find that the additional cost is 1.50.
Therefore, in this situation, the real-world interpretation is that the item costs 12 dollars, and the additional cost, such as taxes, is 1.50 dollars, resulting in a total cost of 13.50 dollars.

542. 50
The fare for this flight was $542.50 which is calculated using least-squares regression line equation. Therefore, the correct answer 542.50
To find the fare for this flight, we will first use the provided least-squares regression line equation to predict the fare and then account for the residual.
Step 1: Use the least-squares regression line equation to predict the fare.
ŷ = 102.50 + 0.65x, where ŷ is the predicted fare and x is the distance in miles.
Step 2: Substitute the given distance (x = 500 miles) into the equation.
ŷ = 102.50 + 0.65(500)
Step 3: Calculate the predicted fare.
ŷ = 102.50 + 325
ŷ = 427.50
The predicted fare for a 500-mile flight is $427.50.
Step 4: Adjust for the residual.
The residual for this flight is 115.0, which means the actual fare is $115 higher than the predicted fare.
Step 5: Add the residual to the predicted fare to find the actual fare.
Actual fare = Predicted fare + Residual
Actual fare = 427.50 + 115
Actual fare = 542.50

Consider the geometric series 1 - x/3 - x^2/9 - x^3/27......
What is the common ratio of the series and for what values of x will the series converge? Determine the function f representing the sum of the series.
The function f representing the sum of the series for x in the interval (-3, 3). Hi! The given geometric series is 1 - x/3 - x^2/9 - x^3/27...
The common ratio of the series is obtained by dividing a term by its preceding term. Let's consider the first two terms:
(-x/3) / 1 = -x/3
Therefore, the common ratio (r) of the series is -x/3.
For a geometric series to converge, the absolute value of the common ratio must be less than 1, i.e., |r| < 1. In this case:
|-x/3| < 1
To find the values of x for which the series converges, we need to solve the inequality:
-1 < x/3 < 1
Multiplying all sides by 3, we get:
-3 < x < 3
So, the series converges for x in the interval (-3, 3).
Now, let's determine the function f representing the sum of the series. For a converging geometric series, the sum S can be calculated using the formula:
S = a / (1 - r)
where a is the first term and r is the common ratio. In this case, a = 1 and r = -x/3. Therefore:
f(x) = 1 / (1 - (-x/3))
f(x) = 1 / (1 + x/3)
This is the function f representing the sum of the series for x in the interval (-3, 3).

A ∪ B = {1, 2, 3, 4, 5, 6, 7, 9}
Step-by-step explanation:
We can find the union of two sets by including all of the numbers in both sets, but without repeating any numbers.
For example:
if A = {1, 2, 3, 4, 5} and B = {4, 5, 6, 7, 8},
then A ∪ B = {1, 2, 3, 4, 5, 6, 7, 8}
We can apply this concept to the problem at hand, but first we need to represent set A as a list of numbers:
They all have to be odd numbers between 0 and 10.
[tex]\implies A[/tex] = {1, 3, 5, 7, 9}
We are given that B = {2, 3, 4, 5, 6}. So, to find the union of A and B, we can combine both sets of numbers and get rid of copies:
A ∪ B = {1, 2, 3, 4, 5, 6, 7, 9}
300 high school students were asked how many hours of tv they watch per day. the mean was 2 hours, with a standard deviation of 0. 5. using a 90% confidence level, calculate the maximum error of estimate.
0. 27%
5. 66%
7. 43%

The maximum error of estimate is 4.75%.
To calculate the maximum error of estimate for the given problem, we will use the formula for margin of error:
Margin of Error = Z-score * (Standard Deviation / √n)
Where:
- Z-score corresponds to the 90% confidence level, which is 1.645
- Standard Deviation is 0.5 hours

Given the height of the cone is 12 m, find the slant height of the cone
a) 5m
b) 13 m
c) 17m
d) 11m
The slant height of the cone is approximately 5 meters.
We can use the Pythagorean theorem to find the slant height of the cone.
The slant height, denoted by l, the height h and the radius r form a right triangle where l is the hypotenuse:
[tex]l^2 = h^2 + r^2[/tex]
In this case, we are given the height h as 12 m, but we are not given the radius r.
However, we know that the slant height is the distance from the apex of the cone to any point on its circular base.
So, we can draw a line from the apex of the cone to the center of its circular base, which will be perpendicular to the base, and we can use this line as the height of a right triangle that also includes the radius r of the circular base.
Then, we can use the Pythagorean theorem to find the slant height l.
The radius r is half the diameter of the circular base, so we need to find the diameter of the base.
Since we are not given the diameter directly, we need to find it using the height h and the slant height l.
To do this, we can draw a cross section of the cone that includes its circular base and its height, and then draw a line from the apex of the cone to a point on the base that is perpendicular to the diameter of the base.
This line will be the height of a right triangle that also includes the radius r of the base and half the diameter of the base.
Then, we can use the Pythagorean theorem to find the diameter of the base.We have:
[tex]l^2 = h^2 + r^2r = sqrt(l^2 - h^2)d/2 = sqrt(l^2 - r^2)d^2/4 = l^2 - r^2d^2 = 4(l^2 - r^2)[/tex]
Substituting the expression for r that we found above, we get:
[tex]d^2 = 4(l^2 - (l^2 - h^2))d^2 = 4h^2d = 2h[/tex]
Now we can substitute this expression for d into the formula for the volume of a cone:
[tex]V = (1/3) * pi * r^2 * hV = (1/3) * pi * ((2h)/2)^2 * hV = (1/3) * pi * h^2 * 4V = (4/3) * pi * h^3[/tex]
We can solve this formula for h:
[tex]h = (3V)/(4*pi)^(1/3)[/tex]
Substituting the given volume of the cone, which we will assume is in cubic meters:
[tex]V = (1/3) * pi * r^2 * h = (1/3) * pi * r^2 * 12V = 16pih = (3(16pi))/(4*pi)^(1/3)[/tex]
h = 4.819 m
Now we can find the slant height using the Pythagorean theorem:
[tex]l^2 = h^2 + r^2l^2 = (4.819)^2 + ((2(4.819))/2)^2l^2 = 23.187l = 4.815[/tex] [tex]m[/tex]

Hillsdale Orchard grows Fuji apples and Gala apples. There are 160 Fuji apple trees and 120 Gala apple trees in the orchard.
Hillsdale Orchard's owners decide to plant 30 new Gala apple trees. Complete the ratio table (click for help) to find the number of new Fuji apple trees the owners should plant if they want to maintain the same ratio of Fuji apple trees to Gala apple trees
To maintain the same ratio of Fuji apple trees to Gala apple trees, the owners of Hillsdale Orchard should: plant 12 new Fuji apple trees when they plant 30 new Gala apple trees.
To find the number of new Fuji apple trees that the owners of Hillsdale Orchard should plant to maintain the same ratio of Fuji apple trees to Gala apple trees, we need to use a ratio table.
First, we need to determine the ratio of Fuji apple trees to Gala apple trees before the new trees are planted. Let's assume that there are currently 40 Fuji apple trees and 100 Gala apple trees. The ratio of Fuji apple trees to Gala apple trees is therefore 40:100, which can be simplified to 2:5.
Next, we need to use this ratio to determine the number of new Fuji apple trees that need to be planted. Since the owners are planting 30 new Gala apple trees, we can use the ratio of 2:5 to find the corresponding number of new Fuji apple trees.
To do this, we need to divide the number of new Gala apple trees by the denominator of the ratio (which represents the number of units of the ratio). In this case, the denominator is 5.
30 (new Gala apple trees) ÷ 5 (denominator) = 6
This means that for every 5 new Gala apple trees, the owners should plant 2 new Fuji apple trees. Therefore, the owners should plant 12 new Fuji apple trees (2 trees for every 5 new Gala apple trees, multiplied by the 30 new Gala apple trees being planted).
In summary, to maintain the same ratio of Fuji apple trees to Gala apple trees, the owners of Hillsdale Orchard should plant 12 new Fuji apple trees when they plant 30 new Gala apple trees.

A dealer made lost of 10% by selling an article for 81,000 naira. How much should he have sold it to make a profit of 15%
The dealer should have sold the article for 103,500 naira to make a profit of 15%.
Let C be the cost price of the composition. According to the problem, the dealer vended the composition at a loss of 10, so he entered 90 of the cost price. thus, 90 of C is equal to 81,000 naira.
C = 81,000
C = 81,000/0.9
C = 90,000
So, the cost price of the composition is 90,000 naira.
Now, let's find out the selling price needed to make a profit of 15 Let S be the needed selling price to make a profit of 15. We know that profit chance is equal to( profit/ cost price) × 100.
Thus,(15/100) × 90,000 =
S- 90,000 , 500
= S- 90,000
S = 90,000 13,500

A measure of goodness of fit for the estimated regression equation is the.
A measure of goodness of fit for the estimated regression equation is the residual standard error (RSE)
It is a measure of goodness of fit for the estimated regression equation. It measures the average amount that the response variable (y) deviates from the estimated regression line, in the units of the response variable.
The RSE is calculated as the square root of the sum of squared residuals divided by the degrees of freedom. A smaller RSE indicates a better fit of the regression line to the data.
It represents the proportion of the variation in the dependent variable that is explained by the independent variable(s) in the model. The value of R-squared ranges from 0 to 1, with higher values indicating a better fit of the model to the data.
