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.
