Nichole can play a video game where each round lasts 7/12 of an hour. She has scheduled 3 3/4 hours to play the game. How many rounds can Nichole play? (Note I don't know which order to do it in)

6 3/7 of a round

Step-by-step explanation:

Total playing time hrs. ÷ each round = total rounds that can be played

3 3/4 = 15/4

15/4 ÷ 7/12

= 15/4 x 12/7

= 180/28

= 6 12/28

= 6 3/7 of a round

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

idk
