Answer:
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 [tex]=1.152\times 10^5[/tex]
[tex]=1.152\times 100000[/tex]
[tex]=115200\ times[/tex]
In a year there are 365 days.
So, in a year the heart beats [tex]=115200\times 365[/tex]
[tex]=42048000\ times[/tex]
Therefore, the heart beats 42048000 times in a year.
