Step-by-step Answer:
Given:
Bill : 3 minutes / apple
Frank : 5 minutes / 2 apples, or 2.5 minutes / apple.
So in 15 minutes, Bill eats 5 apples, and Frank eats 15/2.5 = 6 apples for a total of 11 apples.
To eat completely at least 12 apples, it would take 15 minutes + 1 apples, which means 17.5 minutes, with Bill having eaten 5 5/6 apples, and Frank having eaten 7 apples, exactly.
So the minimum time to eat 12 apples would be 17.5 minutes.
Note: at 18 minutes, they would have eaten 13 1/5 apples.

If the diameter is 80 feet, the radius is 40 ft.
Area of a circle = (pi)(r^2)
A = 3.14 x 40^2
A = 5,042
Answer:
Rather than just multiplying 5/4 with 8, she has to multiply it with 3 + 8. She could put parentheses around the 3 + 8, according to PEMDAS, this would mean that the parenthesis must be solved before multiplication. The correct answer would be:
4/5x - 8 = 3
4/5x = 3 + 8
x = (3 + 8)5/4
x = 11 x 5/4
x = 55/4 or 13.75
First off, an inequality means that there is no equals sign... it will be either greater than (>) or less than (<). So we'll solve yours with the assumption that it is supposed to be greater than...
2s + 5s + 12 > 132
7s + 12 > 132
7s > 132 - 12
7s > 120
s > 120/7
s > 17 1/7
**If it was supposed to be less than instead of greater than, just change the sign. It doesn't affect the outcome.
