Answer:

Perimeter = 42 cm.

Step-by-step explanation:

The  2 legs are equal in length as it is an isosceles trapezoid.

Area of  trapezoid  = (h/2)(a + b)  where a and b are the parallel bases.

So

(5/2) (a + b) = 45

a + b = 45 * 2/5 = 18 cm.

We are given that the length of a leg (L) is 2/3 * sum of the bases, so:

L = 2/3(a + b)

  = 2/3 * 18

   = 12 cm.

The perimeter = a + b + 2L

= 18 * 2*12

= 42 cm.

Rich’s weekly salary is based on the number of pairs of shoes he sells. He is paid a base salary of $25, plus $5 for every pair
Xelga [282]

Answer: option A is the correct answer.

Step-by-step explanation:

s represents the number of pairs of shoes that Rich's sells.

P represents the total pay from selling s pairs of shoes.

He is paid a base salary of $25, plus $5 for every pairs of shoes he sells.

The relationship between his pay and pairs of shoes sold can be represented by the linear equation which is expressed as

p = 25 + 5s

For a week in which he sold 7 pairs of shoes, his total pay would be

p = 25 + 5 × 7

p = 25 + 35

p = $60
