How many times does your heart beat during your lifetime? Round the answer to the nearest power of 10 and then express your answer as the order of magnitude. For instance, if your estimated answer is 3×105, enter 5. If your estimated answer is 8.7×105, you should enter 6 (rounding up to the next power of 10).

Answer:

The answer to your question is:

x = 2869776000 times scientific notation 2.9 x 10 ⁹ times

Explanation:

How many times does your heart beat during you life time?

Process

Given 1 heart beats 70 times per min

Life expectancy = 78 years

70 times ---------------------- 1 min

x --------------------- 60 min

x = (60 x 70) /1

x = 4200 times

4200 times ---------------- 1 hour

x ---------------- 24 h

x = (24 x 4200) / 1

x = 100 800 times

100 800 times ------------ 1 day

x ------------------------ 365 days

x = (365 x 100 800) / 1

x = 36792000 times

36792000 times --------- 1 year

x --------------- 78 years

x = (78 x 36792000) / 1

x = 2869776000 times

x = 2.9 x 10 ⁹ times
