One cubic millimeter of mrs. murphy's blood contains about 5,000,000 red blood cells. there are about 4,900,000 cubic millimeters of blood in her body. determine appropriately how many red blood cells mrs.murphy has in her body total.

approximately 22 trillion blood cells

Step-by-step explanation:

total no. of bloods cells in Mrs.Murphy's body

=no. of blood cells in 1 cubic millimeter × no. of cubic millimeters

= 5,000,000×4,900.000

= 22,000,000,000,000 blood cells

x= 10

It is shown in the figure that TQ=QR

Hence, 8x+20=10x

=> 10x-8x= 20

=>2x=20

=>x= 10
