We can use proportions to solve this problem:
5.2*10^6 red blood cells is to 1 cubic millimeter of blood
as x red blood cells is to 40 cubic millimeters of blood
This can be represented as:
5.2*10^6 / 1 = x / 40
To solve for x, we can cross-multiply and simplify:
5.2*10^6 * 40 = x
208*10^6 = x
2.08*10^8 = x
Therefore, there are 2.08*10^8 red blood cells in 40 cubic millimeters of blood.
If a cubic millimeter of blood contains 5.2*10^6 red blood cells, how many red blood cells are contained in 40 cubic milliliters of blood? Write answer in scientific notation
