Assume a healthy hearts beats exactly 70 times per minute. If individual lives to age 85 years, estimate the number of heartbeats in their lifespan using scientific notation and the correct number of sig figs.

Given :

Number of heart beat in 1  minute , n = 70 .

The individual lives for 85 years .

To Find :

The number of heartbeats in their lifespan .

Solution :

Now , number of minutes in one hour is 60 .

One day contains 24 hours .

Therefore , minutes in one whole day :

Now , 1 year contains 365 days .

( Note : We are not considering any leap years )

Minutes in one year are :

So ,total minutes in 85 years is :

Hence , this is the required solution .

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
