Answer:

18.2 feet^3 of water

Step-by-step explanation:

First let's find 80% of the full capacity, which is 24. To do that, multiply 24 x 0.8, which is 19.2.

Now how much space to the fish take up? There are 8 fish, and each one takes up 1.5 cubic INCHES. 8 x 1.5 = 12 cubic inches, but we need cubic feet. Luckily, there are 12 inches in 1 foot so it'll be a clean and simple 1 foot. The "cubic" part only shows that we're measuring volume.

The 80% capacity - fish capacity = how much water is needed. That will be 19.2 - 1 = 18.2

That's it! Hopefully this helped!

astraxan [27]

Answer:

the correct option is d. 0.02

Step-by-step explanation:

We have the following events:

x: A drought occurd

y: Water rationing.

Therefore, according to the plaster we have:

P [x] = 0.20

P [y | x] = 0.10

Now P [it is a drought and water rationing happens] =

P [x n y] = P [y | x] * P [x] = 0.10 * 0.20 = 0.02

Which means that the correct option is d. 0.02

(X^3)^1/3 <br> What is the simplest form of this expression?

The rule for power to a power is 'keep the base and multiply the powers'.

kari74 [83]
Firstly, you do 90 - 42 to get the amount of brownies sold, which is 48. Then, you put 42 and 48 into a ratio like 42:48. After that, all you need to do is simplify to get 7:8.
