Answer:
45 in, 30 in and 25 in
Step-by-step explanation:
Add the parts of the ratio : 9 + 6 + 5 = 20 parts
Divide the perimeter by 20 to find one part of the ratio.
= 5 ← 1 part of the ratio
9 parts = 9 × 5 = 45
6 parts = 6 × 5 = 30
5 parts = 5 × 5 = 25
45 inches, 30 inches and 25 inches are the measures of each side
Answer:
14
Step-by-step explanation:
I would say 14 because if you multiply 8 by 3 it would equal 24. And that is just below 28. Then, I tried to see if 8 x 4 would work, but that equaled 32. And both of those numbers are in between 28. So, if I multiplied 8 by 3 to get 24, I also multiplied the 4 by 3 which equals 12. So, I would say it would be 14.
It's probably the first one: "People responded to Earth Day with letters..."
Since it's more of a detail that supports a fact, it's not as important as the other three.
