To find the total number of heartbeats occurring in Massachusetts per year, we need to multiply the average number of heartbeats per year by the current population of Massachusetts:
3.5×10^7 heartbeats/year * 7×10^6 people = (3.5 * 7) × (10^7 * 10^6) heartbeats/year
= 24.5 × (10^7 * 10^6) heartbeats/year
= 24.5 × (10^(7+6)) heartbeats/year
= 24.5 × 10^13 heartbeats/year
Expressing the answer in scientific notation, the estimated number of heartbeats occurring in Massachusetts per year is approximately 2.45×10^14 heartbeats/year.
The average human heart beats about 3.5×107 times per year. The current population of Massachusetts is about 7×106 people. About how many heartbeats occur in Massachusetts per year? Write the answer in scientific notation. Express the answer to the exact decimal place
