Question

The expression (w)/(30), where w is a person's weight in pounds, is used to find the approximate number of quarts of blood in the person's body. How many quarts of blood does a 120-pound person have?

Answer 1

A 120-pound person has approximately 4 quarts of blood in their body.

Step-by-step explanation:

To find the approximate number of quarts of blood in a person's body, we can use the expression (w)/(30), where w is the person's weight in pounds. So, for a 120-pound person, we can substitute w = 120 into the expression and calculate:

(120)/(30) = 4 quarts

Therefore, a 120-pound person has approximately 4 quarts of blood.
