Answer:
first solution for first question, and last solution for second questions..
Step-by-step explanation:
Ten to the power of five.
1. the perimeter of a square is always 4 * side, so = 4*31/8 = 31/2 or 15 and 1/2
2. area of a square is always the side multiplied by each other, so: 9/2 * 9/2 = 81/4 or 20 and 1/4
Answer:
The answer is 1, 3, and 5
Step-by-step explanation:
First, you have to solve the equation, making the mixed number fractions into improper fractions. You then get 7/3 x 3/14. You can cross cancel, and thus the equation on the top is equal to 1/2.
Solve the rest of them, the same way you did in the first, and you would get 1, 3, and 5.

27mi/60min=9/20
9mi/20min=xmi/1min
Cross multiply
Divide by 20 on both sides
