Ok. This is just a long multiplication.
How many minutes in an hour?
Multiply it out with 60 at the end as written above.
Then do it also with 80 at the end.
Then you can answer the range is from _____ to _____.
Alternatively, you can calculate it once with 70 at the end.
I get 2,524,608,000
I must of did something wrong
Your result is 10 times smaller than it would be. Maybe you entered one of the 60's as just 6.
60 beats per minute: 2,524,608,000
80 beats per minute: 3,366,144,000
You can answer approx. 2.5 billion to 3.4 billion
Using the average, 70 beats per minute: 2,945,376,000
Approx. 2.9 billion
So how do i put that into one of these answers because these are the choices
Ok. Now you need the average value as a number in scientific notation.
We get an average value of 2,945,376,000.
You can round this off to 3,000,000,000 (3 billion).
