Maël mixes 15 milliliter (mL) of bleach with 3.75 liters (L) of water to make a sanitizing solution for a daycare. The amounts of bleach and water always have to be proportional when he makes sanitizing solution. Which of the following could be combinations of volumes of bleach and water for Maël's sanitizing solution?

You have not provided the options, therefore, I cannot give you an exact answer.
However, I will try to help you with the concept.

First, we need to make all units the same in the problem. I will convert all units to ml.
We have:
amount of bleach = 15 ml
amount of water = 3.75 liters = 3.75 * 1000 = 3750 ml

Now, we will get the ratio between bleach and water:
[tex] \frac{bleach}{water} = \frac{15}{3750} = \frac{1}{250} [/tex]

This ratio is fixed, therefore, to get the right choice:
1- make all units the same
2- for each option, divide the amount of bleach by the amount of water.
The correct choice would be the one giving you [tex] \frac{1}{250} [/tex]

Hope this helps :)

Well it depends on what the answers are

however if we assume the answers are these:

A. Improved sanitation techniques reduce water pollution, which promotes water conservation.

B. Modern sanitation techniques create increasing amounts of water pollution, which hinders water conservation.

C. Communities that invest in sanitation techniques are less likely to invest in water conservation.

D. Communities cannot encourage water conservation without also developing sanitation techniques.

then I believe the answer would be A

Sorry if I got it wrong!
