An average person has 6x10^2 times as many red bloods cells as white blood cells. a small sample of blood has 7x10^3 white blood cells. about how many red blood cells are in the sample?

The sample has 4200 × 10³ cells red blood cells

Explanation:

Assume that the number of white blood cells in an average person is w

We are given that:

Number of red blood cells is 6 × 10² times as many as white blood cells

This means that, in average person:

Number of red blood cells = 6 × 10² × number of white blood cells

Number of red blood cells = 6 × 10² × w >

We are given that:

A sample of blood has 7 × 10³ white blood cells

To know the number of red blood cells in the sample, we will simply substitute with w = 7 × 10³ in equation I

This is done as follows:

Number of red blood cells = 6 × 10² × w

Number of red blood cells = 6 × 10² × 7 × 10³

Number of red blood cells = 4200 × 10³ cells

Hope this helps :)

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.
