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.

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
