Answer :
Answer;
56 kg of water
Solution;
Weight = 62 kg of water in 93 kg of a person
W=km
62=93k;
k=2/3
W=(2/3)84
=56 kg
Therefore; a 84-kg person will have 56 kg of water.
Final answer:
To find the estimated kilograms of water in an 84-kg person, we use the constant of variation obtained from a 93-kg person who contains 62 kg of water. This comes out to approximately 56 kg of water in an 84-kg individual.
Explanation:
The number of kilograms of water in a human body varies directly as the mass of the body. If a 93-kg person contains 62 kg of water, we can find the constant of variation, k, by dividing the mass of water by the mass of the body:
k = 62 kg /93 kg = 0.6667 approx.
Using this constant of variation, we are able to determine the mass of water in an 84-kg person:
Mass of water = k * mass of body
= 0.6667 * 84 kg
= 56 kg approx.
Therefore, an 84-kg person would contain approximately 56 kilograms of water.
