To find the total number of heartbeats in Massachusetts per year, we can multiply the average heartbeats per person per year by the population of Massachusetts:
3.5 × 10^7 beats/person/year × 7 × 10^6 people = (3.5 × 7) × (10^7 × 10^6) beats/year = 24.5 × 10^13 beats/year.
This can be expressed in scientific notation as 2.45 × 10^14 beats/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.(1 point)
