1) One cubic millimeter of Mrs. Murphy's blood contains about 5 x10^6 red blood cells. There are about 4.9x10^6 cubic millimeters of blood in her body. Determine approximately how many red blood cells Mrs. Murphy has in her body total.

24500000000000 or 2.45x10^13

Step-by-step explanation:

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

i think it might be a but you might want a second opinion
