The amount of blood in a person's body, a quarts, is directly proportional to his or her body weight, w pounds. a person who weighs 128 pounds has about 4 quarts of blood. a) find the constant of proportionality. b) write an equation that relates the amount of blood in a person's body to his or her body weight. c) find the weight of a person whose body has about 5 quarts of blood.

Step-by-step explanation:

Let a represent the amount of blood in a Peron's body in quarts.

Let w represent the weight of the Peron's body in pounds.

Therefore,

a is directly proportional to w

a) Let k represent the constant of proportionality. Therefore,

a = kw

A person who weighs 128 pounds has about 4 quarts of blood. This means that

4 = k × 128

k = 4/128 = 0.03125

b) The equation that relates the amount of blood in a person's body to his or her body weight would be

a = 0.03125w

c) the weight of a person whose body has about 5 quarts of blood would be

5 = 0.03125w

w = 5/0.03125 = 160 pounds

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
