We know there are 60 minutes in an hour. To find 2/3 of an hour we divide 60/3 to find 1/3 and multiply by 2 so:
60/3 = 20
20*2 = 40 minutes (which is 2/3 of an hour) to do science
We do the same thing with the 40 minutes. To find 1/4 of 40 minutes we divide 40 by 4 and then multiply it by 3 to get 3/4 so:
40/4 = 10
10*3 = 30 minutes
Then subtract the times 40-30 = 10 minutes

Hope that helps
Given that the number of years should be represented with x, the number of fish in the pond after x years should best be represented with f(x). The equation that would best show the given scenario in the problem above is,
f(x) = 500(2^x)
From the given, 500 is used as the initial population of the fish.
Do you have a specific equation I can help you with. I can explain them better with a problem to look at?

Determine the capacity of the aquarium
This question implies that, we calculate the volume of the prism and this is calculated by multiplying the dimensions of the aquarium. i.e.

Substitute values for the dimensions


Hence, the volume of the aquarium is 2000 cubic inches
