Answer:
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.
, 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).
 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.
 in our given equation and solve for y.



Therefore, there are 50 kg of water in a 75-kg person.
 
        
             
        
        
        
I basically converted them all into decimals and rounded
Team 1- 0.75 
Team 2- 0.8
Team 3- 0.775 
Team 4- 0.825 
Team 5- 0.725 
Team 6- 0.7625
Team 7- 0.7875 
Team 8- 0.8125
Team 4 collected the most

Answer:
sinθ =  
 
Step-by-step explanation:
By applying Pythagoras theorem in the given triangle,
Hypotenuse² = (Leg 1)² + (Leg 2)²
                       = (24)² + 7²
Hypotenuse = √625 = 25
By applying sine rule in the given triangle,
sinθ = 
Since, measure of opposite side = 24
Measure of hypotenuse = 25
Therefore, sinθ =  will be the answer.
 will be the answer.
