Well since there are eight sections of 1-8 that meanst there are 8 different number 5s, and since there are eight sections of 8 it becomes 64, so if my math is correct 8/64ths of the time or 1/8. It might be wrong but I tried.

A golfer hits the golf ball. The quadratic function y = −16x^2 + 80x gives the time x seconds when the golf ball is at height 0
svetlana [45]
You need to calculate the two zeros of the function. The first zero is the "start", the second zero is the "end" of the trajectory.

Well...

0 = x(-16x+80)

First zero is x=0 (the start of trajectory)

Second zero:

-16x+80=0.... x=5! (The end of the trajectory!)

Good luck!

Craig has 36 ounces of flour left in one bag and 64 ounces of flour in another bag. Use the Baking Flour Equivalent table to fin
Ber [7]
So 16 = 3.6, 10 = 2.3 so 20 = 4.6 then add 16 + 20 to get 36 so 3.6 + 4.6 = 8.2
36 ounces = 8.2 cups

36 = 8.2, 8 = 1.8, 20 = 4.6, 36 + 8 + 20 = 64 ounces so 8.2 + 1.8 + 4.6 = 14.6 cups
64 ounces = 14.6 cups

Total cups = 8.2 + 14.6 = 22.8 cups
