A

Hardcover version: 24.99$(100%)
Paperback: 24.99$-40%

Paperback=24.99$x(100%-40%)
=24.99$x60%
=14.99$

The paperback version cost 14.99$.

B and C don’t make much sense sorry tho.

part c and b arent clear but the answer to a is this:

if you want to find 40% of something, start with finding 10% then multiplying by 4 to get 40%. 10% of 24.99 is 2.49. 2.49 times four is 9.96. so thats 40% of 24.99.

to find the price, subtract 9.96 from 24.99.

you get $15.03

In Example 3, the track has 6 lanes that are each 1 meter in width. a. What is the outer perimeter of the track? Round your answ
son4ous [18]

Answer:

Incomplete question, check attachment for the necessary diagram

Step-by-step explanation:

Note in the attachment,

We have two identical straight line of lenght

L1 = L2 = 84.39m

We also have two identical semicircle or radius 36.5m to the first track lane

But this is not the radius of the circle, the radius of the circle will now be 36.5 plus the 6 track lane and we are told that one track lane is 1m, then, the track lane is 6m

So, radius = 36.5+6

r = 42.5m

Then, we need to calculate the perimeter of the semicircle using the formula of perimeter of a circle and dividing by2

P = 2πr/2

P =πr

P = 22/7 × 42.5

P = 133.57 m

Then, the arc 1 is equal to arc 2 which is equal to 133.57 m

A1 = A2 = 133.57 m

Now we have all the dimensions,

Then, the perimeter can be calculated by adding the length of the sides

The perimeter of the field = Lenght of the two straight lines plus the length of the two semicircle arc

P = L1 + L2 + A1 + A2

P = 84.39 + 84.39 + 133.57 + 133.57

P =435.923 m

So, to the nearest meter

P ≈ 436m

The perimeter of the track is 436m
