The number of goldfish in a tank is 12, and the volume of the tank is 45 cubic feet. what is the density of the tank?
0.27 goldfish per cubic foot
3.75 goldfish per cubic foot
33 goldfish per cubic foot
57 goldfish per cubic foot

0.27 goldfish per cubic foot

Step-by-step explanation:

The formula to calculate density is given by :-

Given: The number of goldfish = 12

The volume of the tank = 45 cubic feet.

Now, the density of the tank is given by :-

Hence, the density of the tank = 0.27 goldfish per cubic foot

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
