Answer:
135 minutes
Explanation:
36 cupcakes in 45 minutes can be written as
, so to find how long 108 will take, you can find it by equating these two fractions:
= 
Simplify by cross division:
divide 45 and 108 by 3 to simplify into this:
=
x = 15
The rate is 3, so 45 • 3 = 135 minutes.
Another way of looking at it is this:
108 ÷ 36 = 3 this is the rate that you need to multiply the amount of time that it takes to make the cupcakes, so:
45 • 3 = 135 minutes.

1. Domain.
We have

So there is a hole or an asymptote at x = 3 and x = -1 and we know, that answer B) is wrong.
2. Asymptotes:
We have only one asymptote at x = -1 (and hole at x = 3), thus the correct answer is A)
We have

To find this answer, we need to understand how to get the Volume.
We get the volume by the formula: L x W x H
L = Length
W = Width
H = Height
So, we can see that there are 3 units required to know for getting the volume, if that's true, then, to do the inverse operation of finding the volume. That can be done by using thie formula:
a= edge
Solving for a
a=V⅓=216⅓=6
<h2>So hence, each of the Cube shaped Fish Tank is 6in³</h2>now, let's look at how to find whether our answer is right or wrong
6x6=36
36x6=216
So hence, our answer is right!
