Asap the density of a fish tank is 0.5³. there are 30 fish in the tank. what is the volume of the tank? you so much!

I believe you meant:

0.5 fish

ft^3

instead of:

The density of a fish tank is 0.5 \frac{fish}{feet} ³. fish^3 has no meaning. ;)

Try this:

30 fish

= 60 ft^3. If the tank were a cube, it'd have side length 3.9 feet.

0.5 fish / ft^3

answer: i don't understand. what are the options

step-by-step explanation:

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
