Answer:
bc
Step-by-step explanation:
2:9 is equivalent to
18: 81 because is 2*9 : 9*9
12:54 because is 2*6 : 9* 6
20 nickels = 1 dollar
So, do 20 x 17.
20 x 17 = 340 nickels which is $17.
The answer is 340 nickels!
The dimensions would be 29 by 29.
To maximize area and minimize perimeter, we make the dimensions as close to equilateral as possible.
Dividing the perimeter by the number of sides, we have
116/4 = 29
This means that both length and width can be 29.
13 is 141. A octagon has 1080 degrees and if you add all the angles up you get 939 and 1080-930=141
