Answer 2

$
`1.21* 10^(7)` per minute.

Step-by-step explanation:

We have been given that a certain animated movie earned $
`1.1*10^(9)` in revenues at the box office. The movie lasts
`9.1*10^(1)` minutes.

To find the revenue earned per minute of the movie we will will divide
`1.1*10^(9)` by
`9.1*10^(1)`.

`\text{The revenue earned per minute by the movie}=(1.1*10^(9))/(9.1*10^(1))`

Using quotient rule of exponents we will get,

`\text{The revenue earned per minute by the movie}=(1.1)/(9.1)*10^((9-1))`

`\text{The revenue earned per minute by the movie}=(1.1)/(9.1)*10^(8)`

`\text{The revenue earned per minute by the movie}=0.1208791208791209* 10^(8)`

We can write 0.1208791208791209 as
`1.208791208791209*10^(-1)`.

`\text{The revenue earned per minute by the movie}=1.208791208791209* 10^(-1) * 10^(8)`

Using product rule of exponents we will get,

`\text{The revenue earned per minute by the movie}=1.208791208791209* 10^(-1+8)`

`\text{The revenue earned per minute by the movie}=1.208791208791209* 10^(7)`

Upon rounding our answer to two decimal places we will get,

`\text{The revenue earned per minute by the movie}=1.21* 10^(7)`

Therefore, the movie had earned a revenue of $
`1.21* 10^(7)` per minute.
