Question

If Kelly’s heart beats an average of 1x10^2 times per minute about how many times does Kelly’s heart beat in a year? ( Hint: 1 year is 525,600 minutes.)

Answer 1

52,560,000 beats per year

Explanation:

Since you are multiplying 1 by 10^2 then you would just get what 10^2 is. 10^2 can be also represent as 10*10 which would equal out to 100. Now that you know how many times her heart beats per minute you must multiply by 525,000 which would be 100*525,600 and would equal out to 52,560,000.
