The volume of a fish tank is 30 cubic feet. if the density is 0.3 fish over feet cubed, how many fish are in the tank? select one: a. 100 b. 10 c. 9 d. 3

The volume of the tank is given as 30 cubic feet.

The density is 0.3 fish / 1 cubic foot.

To find the number of fish, multiply the volume by the density:

30 x 0.3 = 9

There are 9 fish.

x+14

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
