To find the total number of heartbeats in Massachusetts per year, we need to multiply the average number of heartbeats per year by the population.
The average number of heartbeats per year is given as 3.5 × 10^7.
The population of Massachusetts is given as 7 × 10^6.
To multiply these two numbers together, we can multiply the coefficients and add the exponents (since they have the same base).
(3.5) * (7) = 24.5
10^7 * 10^6 = 10^(7+6) = 10^13
Putting it all together, the total number of heartbeats in Massachusetts per year is 2.45 × 10^13.
Thus, the answer is 2.45e+13.
The average human heart beats about 3.5 × 10^7 times per year. The current population of Massachusetts is about 7 × 10^6 people. About how many heartbeats occur in Massachusetts per year? Write the answer in scientific notation. Express the answer to the exact decimal place. (hint: the answer is equal to 2.45e+14)
