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)
To find the total number of heartbeats in Massachusetts per year, we need to multiply the average number of heartbeats per person per year by the population of Massachusetts.
Number of heartbeats in Massachusetts per year = average number of heartbeats per person per year * population of Massachusetts
= 3.5 × 10^7 * 7 × 10^6
= 24.5 × 10^13
= 2.45 × 10^14
So, approximately 2.45 × 10^14 heartbeats occur in Massachusetts per year.
To calculate the total number of heartbeats that occur in Massachusetts per year, we need to multiply the average number of heartbeats per person by the population of Massachusetts.
The average human heart beats about 3.5 × 10^7 times per year.
The current population of Massachusetts is about 7 × 10^6 people.
Therefore, the total number of heartbeats in Massachusetts per year is:
(3.5 × 10^7) × (7 × 10^6)
To multiply these numbers, we can add the exponents and multiply the coefficients:
3.5 × 7 × 10^(7+6)
The coefficient is 3.5 × 7 = 24.5.
The exponent is 7 + 6 = 13.
Therefore, the total number of heartbeats in Massachusetts per year is approximately 24.5 × 10^13.
Expressing this answer to the exact decimal place, it becomes 2.45 × 10^14.
To find the total number of heartbeats that occur in Massachusetts per year, we need to multiply the average number of heartbeats per person by the population of Massachusetts.
The average human heart beats about 3.5×10^7 times per year, and the current population of Massachusetts is about 7×10^6 people.
To calculate the total number of heartbeats per year, we can multiply these two numbers together:
Total heartbeats per year = Average heartbeats per person × Population of Massachusetts
Total heartbeats per year = 3.5×10^7 × 7×10^6
Now, we can simplify the expression:
Total heartbeats per year = (3.5 × 7) × (10^7 × 10^6)
Total heartbeats per year = 24.5 × 10^13
Since 24.5 is a decimal number, we express the answer in scientific notation as:
Total heartbeats per year = 2.45 × 10^14
Therefore, approximately 2.45 × 10^14 heartbeats occur in Massachusetts per year.
