I NEED HELP WITH #5 PLZ ! Need by midnight and plz tell me how you solved it. Thank you in advance.
Nikitich [7]

Answer:

Perimeter A  = 122.5

Step-by-step explanation:

Set up the following proportion

The Perimeter of B = 12 + 9 + 9 + 5

The Perimeter of B = 35

7/2 = x/PerimeterB

7/2 = x / 35                   Cross multiply

7*35 = 2x                      Combine the left side

245  = 2x                      Divide by 2

245/2 = 2x/2                Do the division

122.5 = x

The Perimeter of A = 122.5

Problem 3

If you compare the sides opposite the angle marked with a single arc, you will get the scale factor.

If these triangles are similar, and one of the sides opposite their markings will give you the scale factor

18/7.2 = x/1 where x is the scale factor going from the larger to the smaller triangle.

2.5 = x

So if you multiply the smaller triangle's sides by 2.5 you get the larger triangle.

CAN ANYONE PLEASE (WHO IS AN EXPERT AT MATHEMATICS) HELP ME WITH THIS.
NikAS [45]

Answer:

5 units were bought

Step-by-step explanation:

Firstly, let us calculate the total amount paid

If what was paid was $9.45, this cost includes the price of the coupon subtracted

Returning the coupon price, we have the total as;

9.45 + 0.5 = $9.95

So to get the number bought, we divide this total by the price for one

We have this as;

9.95/1.99 = 5
