Answer: 216 millilitres

Step-by-step explanation:

From the question, you are given that there are 3 milliliters of compound A used for every 5 milliliters of compound B. That means compound A and B are in ratio 3 to 5. That is,

A : B = 3 : 5

If a chemist wants to make 576 milliliters of the drug, then find the ratio of compound A.

To do that, first add the ratio of both together, 3 + 5 = 8

For compound A,

3/8 × 576

1728/8 = 216 millilitres

Therefore, 216 millilitres of compound A are needed.

    A rectangular prism has a length of 2 1/2 meters, a width of 4 meters, and a height of 2 1/4 meters.
aalyn [17]
First we need to convert our fractions into decimals, it's just a lot easier to work with.
2 1/2 is equal to 2.5
2 1/4 is equal to 2.25
Then we plug our numbers into the formula used to find the volume of a rectangle:
V=L*W*H
Volume equals Length times Width times Height.
V=2.5*4*2.25
V=22.5
22.5 is already in decimal form, or if you'd rather have a mixed number, your answer is 22 \frac{1}{2}
