Answer:
Step-by-step explanation:
For similar figures, side lengths (and any other linear measure) are proportional. Areas are proportional to the square of the scale factor for side lengths.
Perimeter 1/Perimeter 2 = CD/EF
21/18 = CD/6
CD = 6(21/18)
CD = 7 . . . cm
__
Area 2/Area 1 = (Perimeter 2/Perimeter 1)²
Area 2/98 = (18/21)²
Area 2 = 98(6/7)²
Area 2 = 72 . . . cm²
So here is how we are going to find the answer. Firstly, we deduct 58 from 76 and we got 18. The decrease is $18. Now, we are going to find out how many percent is 18 of 76. So we divide 18 by 76 multiplied by 100 and we get 23.7%. Hope this answers your question. Have a great day!

Answer:
Each pipe is 24m
Step-by-step explanation:
<u>Given:</u>
- three pipes
- combined equal 72m
- let the variable x represent the length of 1 pipe
<u>Algebraic Expression</u>:
3 pipes times length equals 72m (the total length)
3x = 72, we want x to be alone so divided both sides by 3
3x / 3 = 72 / 3
x = 24
