The number of kilograms W of water in a human body varies directly to the mass of body. A 96-kg person contains 64 kg of water. How many kilograms of water are in a 60-kg person?

40 kg of water

Cross multiply and solve for x.

96/64 = 60/x

bro this is not helping me i need the answerrrrrr

How

96x = 64 * 60

96x = 3840

x = 40

To find the number of kilograms of water in a 60-kg person, we can set up a proportion based on the given information.

We know that the number of kilograms of water (W) in a human body varies directly with the mass of the body. In other words, there is a constant ratio between the two variables.

Let's set up the proportion using the given data:

W₁ / M₁ = W₂ / M₂

where W₁ = 64 kg (water in a 96-kg person),
M₁ = 96 kg (mass of the 96-kg person),
W₂ = unknown (water in a 60-kg person),
and M₂ = 60 kg (mass of the 60-kg person).

Plugging in the values, we get:

64 kg / 96 kg = W₂ / 60 kg

To find W₂, we can cross multiply:

64 kg * 60 kg = W₂ * 96 kg

Dividing both sides by 96 kg:

(64 kg * 60 kg) / 96 kg = W₂

Simplifying the calculation:

= 3840 kg-kg / 96 kg = W₂

= 40 kg = W₂

Therefore, a 60-kg person contains 40 kg of water.

This is hard to understand I don’t get it because I need to calculate how many kilograms. Tell me the calculation not just for a 94 kg person ( that’s heavy )

The answer is 56

to don't be angry the answer is own your own don't fight I have no answer so sad for me

My online classes says that the correct answer is 44.
