Answer:
you would multiply 2 * 4.87 and then add that to 9.74 and then you do that to everyone and then one of them will get you your answer and I am not sure about the answer but I think its b
Step-by-step explanation:
Answer:
The value of the coin when Consuelo originally purchased it is $9.74 ⇒ C
Step-by-step explanation:
The form of the linear equation is;
y = m x + b, where
m is the slope of the line (The rate)
b is the y-intercept (initial amount, value y at x = 0)
∵ The value of a collectible coin can be represented by the equation
y = 2 x + 9.74
→ Compare it with the form of the linear equation above
∴ m = 2
∴ b = 9.74
∵ x represents the number of years that Consuelo has owned the coin
∵ y represents the total value, in dollars, of the coin
→ That means the value of y at x = 0 is the value of the coin when
Consuelo originally purchased it
∵ b represents the value of y at x = 0
∵ b = 9.74
∴ The value of the coin when Consuelo originally purchased it is $9.74

Answer:
35
Step-by-step explanation:
Answer:
y = 35°
Step-by-step explanation:
if the lines are parallel, the alternate interior angles theorem applies ("if a transversal intersects two parallel lines then alternate interior angles are congruent"). so since we know that the lines are parallel, the alternate interiors are congruent so 70=2y. from there, divide both sides by 2 to isolate y (division property of equality) and y=35.

Terry leaves his house
riding a bike at 20
km/h. Sally leaves 6 h
later on a scooter to
catch up with him
travelling at 80 km/h.
How long will it take
her to catch up with
him?
Answer:
2
Step-by-step explanation:
So let's call the time she needs to catch up "x", and so Terry's rate would be x-6 since he left home 6 hours earlier. Then we multiply the rates to get 20x - 120 = 80x. The answer is -2, but we can just say 2.
Checking our answer, that means if it took Sally 2 hours, it took Terry 8 hours for he left home 6 hours earlier. So 8 times 20 = 160km traveled. 2 times 80 = 160km traveled. Same distance.

Question 7 options: A raffle sells 1000 tickets for $35 each to win a new car. What is the probability of winning the car
Answer:
it would be 1/1000 assuming only 1 ticket sold to 1 person each; if a person bought more than 1 ticket then there odds of winning increase
Step-by-step explanation:
The probability of winning the car is 0.001.
What is the probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favorable outcomes/Total number of outcomes
Given that, a raffle sells 1000 tickets for $35 each to win a new car.
Here, we know that there is a total of 1000 tickets. If there is only one car, then definitely only one wins the raffle. The probability of winning is also dependent on the number of tickets one will purchase. But for this problem, we are going to assume that only one raffle can be bought by one person. Thus, the probability of winning a new car is simply
P(E)= Number of raffle tickets one can buy/Total number of raffle tickets
= 1/1000
= 0.001
Therefore, the probability of winning the car is 0.001.

A person borrowef Rs 16000 from a bank at 12.5% pet annum simple intrest and lent the whole amount to shopkeeper at the sam rate of compound interest.How much will he gain in 2 years?
Answer:
The amount he gains in 2 years is Rs. 250
Step-by-step explanation:
The parameters of the amount borrowed from the bank are;
The amount borrowed, P = Rs. 16,000
The interest rate of the amount borrowed, R = 12.5%
The number of years, T = 2 years
The simple interest, I = (P × R × T)/100 = (Rs. 16,000 × 12.5 × 2)/100 = Rs. 4,000
The total amount the person is to pay bank to the bank = P + I = Rs. 16,000 + Rs. 4,000 = Rs. 20,000
The parameters of the amount lent to the shopkeeper are;
The amount lent, P = Rs. 16,000
The compound interest rate of the amount lent, R = 12.5%
The number of years, T = 2 years
The amount he receives from the shopkeeper after 2 years, A = P·(1 + R/n)^(n × T) = Rs. 16,000 × (1 + 0.125/1)^(1 × 2) = Rs. 20,250
The amount he gains in 2 years = The amount he receives from the shop keeper - The amount he gives to the bank = Rs. 20,250 - Rs. 20,000 = Rs. 250
The amount he gains in 2 years = Rs. 250.

Answer:
x = [tex]\frac{15}{2}[/tex] , x = 1
Step-by-step explanation:
(a)
[tex]\frac{4x-1}{2}[/tex] = x + 7 ( multiply both sides by 2 to clear the fraction )
4x - 1 = 2x + 14 ( subtract 2x from both sides )
2x - 1 = 14 ( add 1 to both sides )
2x = 15 ( divide both sides by 2 )
x = [tex]\frac{15}{2}[/tex]
(b)
3x + 2 = [tex]\frac{2x+13}{3}[/tex] ( multiply both sides by 3 to clear the fraction )
9x + 6 = 2x + 13 ( subtract 2x from both sides )
7x + 6 = 13 ( subtract 6 from both sides )
7x = 7 ( divide both sides by 7 )
x = 1

Answer: None of the lines are parallel to one another
======================================================
Explanation:
Solve each equation for y
Line a:
4y+x = 8
4y = -x+8
y = (-x+8)/4
y = (-x/4) + (8/4)
y = (-1/4)x + 2
This equation is in the form y = mx+b with slope m = -1/4
---------------
Line b:
2y+x = 4
2y = -x+4
y = (-x+4)/2
y = (-x/2) + (4/2)
y = (-1/2)x + 2
The slope is m = -1/2. It is not parallel to line a because parallel lines must have the same slope (but different y intercept).
-----------------
Line c:
2y = -3x+6
y = (-3x+6)/2
y = (-3x/2) + (6/2)
y = (-3/2)x + 3
The slope here is m = -3/2. it is not parallel to line a, and it is not parallel to line b either for similar reasons discussed above.
-----------------
In summary, none of the three lines are parallel to one another. The graph below visually confirms this. Each pair of lines intersects at exactly one location, showing they cannot be parallel.
The length of a rectangular swimming pool is 20 feet greater than the width. The surface area of the pool is 1,500 square feet. What are the length and width of the pool?
Answer:
750
Step-by-step explanation:
The length and width of the swimming pool is 50feet and 30 feet respectively.
What is surface area ?The amount of space covering the outside of a three dimensional space is called surface area.
Formula for the surface area of rectangular swimming poolsurface area = length × breadth
According to the given question
The length of the rectangular swimming pool is 20 feet greater than the width.
and, the surface area of the pool is 1,500 square feet.
Let the width of the rectangular pool be x.
⇒ length of the pool = 20+x
therefore,
surface area of pool = length × breadth
⇒1500 = x×(20+x)
⇒[tex]1500= 20x+x^{2}[/tex]
⇒[tex]x^{2} +20x-1500=0[/tex]
⇒[tex]x^{2} +50x-30x-1500=0[/tex]
⇒[tex]x(x+50)-30(x+50)=0[/tex]
⇒[tex](x-30)(x+50)=0[/tex]
⇒x=30 and -50(not possible)
⇒x=30 feet
so, the width of the pool is 30 feet.
⇒ length of the pool = x+20 = 30+20 = 50 feet.
Hence, the length of the pool is 50 feet and width of the pool is 30 feet.

Complete each statement given w = 2(cos(90o) + i sin (90o)) and z = StartRoot 2 EndRoot (cos(225o) + i sin(225o)). In rectangular form, w = 0 + i. In rectangular form, z = – 1i. In rectangular form, w + z = –1 + i. In polar form w + z = StartRoot 2 EndRoot (cos(o) + i sin(o)
This question is based on the concept of polar form.Therefore, the expression in polar form is [tex]\bold {z = \sqrt{10(cos108.43\; + \; i \; sin108.43)}}[/tex]
Given the following complex numbers in:
w = 2(cos(90°) + i sin (90°))
As we know that,
sin 90 degree = 1
cos 90 degree = 0
Put these values in given equation,
We get,
w = 2(0+i(1))
w = 2(0)+2i
w = 0+2i
Hence the value of w in rectangular form is 0+2i .
Now solving for z:
z =√2(cos(225°) + i sin(225°))
z = √2(-1/√2+ i (-1/√2))
z = -√2/√2 - √2(-1/√2)i
z = -1 + 1i
Therefore, the value of z in rectangular coordinate is -1+ 1i.
Now solving for w + z:
w + z = 0+2i + (-1+1i)
w+z = 0+2i-1+i
w+z = -1+3i
Write w+z in polar form,
Get the modulus
|w+z| = √(-1)²+3²
|w+z| = √1+9
|w+z| = √10
Get the modulus
= tan^-1(-3)
= -71.56
[tex]\Theta[/tex] = 180 - 71.56
[tex]\Theta[/tex] = 108.43
Therefore, the expression in polar form is,[tex]\bold{z = \sqrt{10(cos108.43\; + \; i \; sin108.43)}}[/tex]
