The number of kilograms of water in a human body varies directly as the mass of the body. an 87-kg person contains 58 kg of water. how many kilograms of water are in a 75-kg person?
nothing kg of water are in a 75-kg person.

50 kg water.

Step-by-step explanation:

We have been given that the number of kilograms of water in a human body varies directly as the mass of the body.

We know that two directly proportional quantities are in form , where y varies directly with x and k is constant of variation.

We are told that an 87-kg person contains 58 kg of water. We can represent this information in an equation as:

Let us find the constant of variation as:

The equation represents the relation between water (y) in a human body with respect to mass of the body (x).

To find the amount of water in a 75-kg person, we will substitute in our given equation and solve for y.

Therefore, there are 50 kg of water in a 75-kg person.
