There were 32 volunteers to donate blood. unfortunately, n of the volunteers did not meet the health requirements, so they couldn’t donate. the rest of the volunteers donated 470 milliliters of blood each. how many millimeters of blood do each volunteer donate write your answer in a expression

We have been given that there were 32 volunteers to donate blood.

Let n be number of volunteers that did not meet the health requirements to donate blood. So we can find the number of volunteers that donated blood by subtracting n from total number of volunteers.

To find amount of blood donated by each volunteer we will divide the total amount of donated blood (470 ml)  by number of volunteers that donated blood.

Therefore, the expression that represents amount of blood donated by each volunteer will be milliliter per volunteer.

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
