Mathematics: The amount of blood in a person s body varies directly with body weight. a person who weighs 160 lb has about 4.6 qt of blood. about how many quarts of blood are in the body of a 175-lb person? -how can you find the constant of variation? -can you write an equation that relates quarts of blood to weight? -how can you use the equation to determine solution?

I got the answer 9.12. In the hundredths place, it would be 2.Hope this helps! :D...

The amount of blood in a person s body varies directly

Step-by-step explanation:

Given that amount of blood is directly linked to body weight of the person.

$b\propto W$

b=kW

$\frac{b}{W}=k$

b = Amount of blood

W = weight of the person

k = proportionality constant or constant of variation

1) Given that, person who weighs 160 lb has about 4.6 quart of blood.

b = 4.6 quart, W = 160 lb

$k=\frac{b}{W}=\frac{4.6 quart}{160 lb}=0.02875 quart/lb$

The constant of variation is of value 0.02875 quart/lb.

2) An equation that relates quarts of blood to weight:

$b=0.02875 quart/lb\times W$

3) If, b = ?,W = 175 lb

$b=0.02875 quart/lb\times W$

$b=0.02875 quart/lb\times 175 lb=5.03125 quart$

5.03125 quarts of blood are in the body of a 175-lb person.
