Answer:

370 millimeters of compound B is needed for 666 millimeters of solution.

Explanation:

Given that:

4 millimeters of compound A are used for every 5 millimeters of compound B.

The scientist wants to make 666 millimeters of solution.

Let,

x be the multiplier number of the compounds in the solution.

Then,

4x + 5x = 666

9x = 666

Dividing both sides by 9


(9x)/(9)=(666)/(9)\\x=74

Millimeters of compound B = 5x = 5(74) = 370 millimeters

Hence,

370 millimeters of compound B is needed for 666 millimeters of solution.
