Brad had 20 minutes to do a three-problem quiz. He spent 11 3 4 minutes on question A and 3 1 2 minutes on question B. How much time did he have left for question C?

14

Step-by-step explanation:

time left for question C  = Total time - ( sum of time spent on questions A and B)

sum of time spent on questions A and B = 11 3/4 + 3 1/2 =

Convert the mixed fractions to decimals to solve more easily

11.75 + 3.5 = 14.25 = 15 1/4

Time left for question C = 20 - 151/4 = 14 3/4

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
