There are 24 fish in an aquarium. If 1/8 of them are tetras, and 2/3 of the remaining fish are guppies, how many guppies are in the aquarium?

14 guppies

Step-by-step explanation:

1/8th of 24 is 3 which leaves 21 remaining

2/3 of 21 is 14 as each third is 7

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.'

the answer is 62.8 cubic units
