Answer:

1.5 per hour : 1.2 per hour

Step-by-step explanation:

The computation of the ratio is shown below:

For norma, the one pool would be

= 12  pools ÷ 8 hours

= 1.5 per hour

And for albert, the one pool would be

= 9 pools ÷ 7.5 hours

= 1.2 per hour

So the ratio between them is

1.5 per hour : 1.2 per hour

To solve this problem you must apply the proccedure shown below:

 1. You have the following logarithm:

 <span>log(2)n=4

 2. Therefore, you con rewrite it as below:

 loga(b)=logb/loa
</span>
 3. Therefore, you have:

 log(2)n=4⇒log(n)/log(2)=4
 
 4. Then, you obtain:

 log(n)=4log(2)

 5. Therefore, as you can see, the answer for the exercise shown above is the last option, which is:

 log(n)=4log(2)
