Question

the human heart beats approximately 1.152x10^5 times per day. approximately how many times a year does the heart beat?

Answer 1

To find out how many times a human heart beats in a year, multiply the number of heartbeats per day by the number of days in a year, resulting in approximately 42,048,000 heartbeats per year.

Step-by-step explanation:

The human heart beats approximately 1.152×10⁵ times per day. To determine how many times the heart beats in a year, we must multiply the daily heartbeat count by the number of days in a year. Assuming a non-leap year with 365 days, the calculation would look like this:

Multiply the daily beat count (1.152×10⁵) by the number of days in a year (365).

• 1.152×10⁵ × 365 = 4.2048×10⁷heartbeats per year.

The human heart therefore beats approximately 42,048,000 times a year.

Answer 2

The heart beats 42048000 times in a year.

Step-by-step explanation:

Given:

The human heart beats approximately 1.152x10^5 times per day.

Now, to find approximately how many times in a year does the heart beat.

In a day the heart beats
`=1.152* 10^5`

`=1.152* 100000`

`=115200\ times`

In a year there are 365 days.

So, in a year the heart beats
`=115200* 365`

`=42048000\ times`

Therefore, the heart beats 42048000 times in a year.
