The total number of heartbeats per year in Massachusetts can be calculated by multiplying the number of people in Massachusetts by the average number of heartbeats per person per year:
(7 x 10^6) x (3.5 x 10^7) = 24.5 x 10^13
Since 24.5 is between 1 and 10, this answer can be written in scientific notation as:
2.45 x 10^14
Therefore, about 2.45 x 10^14 heartbeats occur in Massachusetts per year.
The average human heart beats about 3.5 times 10^7 times per year. The current population of Massachusetts is about 7 times 10^6 people. About heartbeats occur in Massachusetts per year? Write the answer in scientific notation. Express the answer to the exact decimal places.
