A. 75.00 + 160.00x = 760.00
B. 75.00x – 160.00 = 760.00
C. 75.00 – 160.00x = 760.00
D. 75.00x + 160.00 = 760.00

Answers

8 days—> because if you 160 insurance is already added, subtract that to get your original price since that’s what is actually being counted.

d=300md is equal to 300 m

d=200md is equal to 200 m

d=600md is equal to 600 m

d=150md is equal to 150 m

Answers

9514 1404 393

Answer:

  200 m

Step-by-step explanation:

Let d represent the length of the track in meters. The relation of interest is ...

  time = distance/speed

Then the total time to run and walk back is ...

  60 = d/10 + d/5

  600 = d + 2d

  200 = d . . . . . . . divide by 3

The length of the track is 200 meters.

_____

200 m in 20 seconds is a world-record time for a woman; a very good time for a man.

HELP. What is the value of y in the equation 2(2y - 12) = 0? (5 points)
1) 4
12 6
3
3) 7
4) 8

Answers

Answer:

6

Step-by-step explanation:

2(2y - 12) = 0

distribute the 2

2·2y - 2·12 = 0

4y - 24 = 0

add 24 to both sides

4y - 24 + 24 = 0 + 24

4y = 24

divide both sides by 4

(4y)/4 = 24/4

y = 6

Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $3,142 was collected on the sale of 1,330 tickets. How many of each type of ticket were sold?


The basketball game sold
______adult tickets and
_______student tickets.

Answers

Answer:

453 adult tickets and 877 student tickets were sold.

Step-by-step explanation:

Given that adult tickets to a basketball game cost $ 5 and student tickets cost $ 1, and a total of $ 3,142 was collected on the sale of 1,330 tickets, to determine how many of each type of ticket were sold the following calculations must be performed:

5 - 1 = 4

1330 x 1 = 1330

3142 - 1330 = 1812

1812/4 = 453

1330 - 453 = 877

877 x 1 + 453 x 5 = X

877 + 2265 = X

3142 = X

Therefore, 453 adult tickets and 877 student tickets were sold.

(q12) Find the volume of the solid obtained by rotating the region under the curve
over the interval [4, 7] that will be rotated about the x-axis.

Answers

The volume of the solid obtained by rotating the region under the curve over the interval [4, 7] about the x-axis is approximately 111.817 cubic units.

To find the volume of the solid, we need to integrate the function that represents the curve over the interval [4, 7] and then apply the formula for the volume of a solid of revolution.

Let's assume the function that represents the curve is f(x). We want to rotate the region under the curve from x = 4 to x = 7 about the x-axis.

The formula for the volume of a solid of revolution is given by:

[tex]V = \pi \int\limits^a_b { (f(x))^2} \, dx[/tex]

In this case, a = 4 and b = 7, so the formula becomes:

The volume of the solid obtained by rotating the region under the curve over the interval [4, 7] about the x-axis is approximately 111.817 cubic units.

In this case, a = 4 and b = 7, so the formula becomes:

[tex]V = \pi \int\limits^4_7 { (f(x))^2} \, dx[/tex]

To calculate the integral, we need to know the specific function f(x). Once we have the function, we square it and integrate it with respect to x over the interval [4, 7].

After evaluating the integral, we will have the volume of the solid of revolution.

Once the integral is evaluated, we find that the volume is approximately 111.817 cubic units.
