Chantel wanted to add fish to her new fish tank. The pet store recommended that each fish needs 0.5 cubic feet of water for each fish. Chantel wants to put 7 fish in her tank and the tank is 2.5 feet long and 0.5 feet deep. How high should Chantel fill the water in the tank?

  2.8 feet high

Step-by-step explanation:

The volume of water required for the 7 fish is ...

  (7 fish)(0.5 ft³/fish) = 3.5 ft³

The height of the water required is computed using the formula for the volume of a cuboid:

  volume = length × depth × height

  3.5 ft³ = (2.5 ft)×(0.5 ft)×height

  height = (3.5 ft³)/(1.25 ft²) = 2.8 ft

Chantel should fill the water in the tank to a height of 2.8 feet.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
