The human body produces 1.5 x 10⁷ red blood cells every second. How many red blood cells, expressed in scientific notation, does the human body produce in a 60-second period?

Sagot :

1.5 x 10^7 x 60 = 1.5 x 10^8 x 6 = 9 x 10^9 red blood cells.
15x[tex]10 ^{7} [/tex]=15000000
Make a relationship, for every second, there is 5 million red blood cells therefore its:
5million/s

60s(15000000/s)=900000000.

Hope this helps
