Question

the volume of blood in a persons body is proportional to body weight. a person who weighs 170 pounds has approximately 5 quarts of blood. estimate the number of quarts of blood in a person who weighs 190 pounds. complete the proportion, where the ratios have volumes of blood in the numerators and body weights in the denominators. (\frac{x}{square}=\frac{square}{square}) (do not simplify.)

Explanation:

Step1: Set up proportion

Let $x$ be the volume of blood for a 190 - pound person. We know that for a 170 - pound person, the volume of blood is 5 quarts. The proportion is $\frac{x}{190}=\frac{5}{170}$.

Answer:

$\frac{x}{190}=\frac{5}{170}$
