Enrique drank 23⁄16 cups of coffee in 21⁄2 hours. how much coffee did he drink each hour?           a. 4⁄5 of a cup   b. 515⁄32 cups   c. 11⁄8 cups   d. 7⁄8 of a cup

7/8 cup/hr (Answer D)

Step-by-step explanation:

You're being asked to find the unit rate, the rate at which Enrique drank coffee each hour.  Divide 2 3/16 cups by 2 1/2 hours:

2 3/16 cups         35          5

=    ÷  = (35/16)*(2/5) = 70/80 cup/hr = 7/8 cup/hr

2 1/2 hours          16           2

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

other answer is correct. i had used the radius of the radius somehow. a website:
