Answer: 12%
Step-by-step explanation: Percent easily found with 100. 25*4=100. 3*4=12
12/100=12%
Answer:
17.) 12
18.) 1/15
Step-by-step explanation:
2 ÷ 
This problem is asking how many
's can go into 2 blocks. If you divide one box into 6 parts, each tiny box will be
of the whole. Divide the other box into 6 parts as well, and you will get 12 of these
parts. Check your answer by multiplying 12 by
. The answer is
which is also equal to 2.
÷ 5
For this one, think of it as we have one big box divided into thirds. We want to divide each
portion by 5. So you should have 5 tiny boxes in each
which gives you a total of 15 boxes. But if we look at it as one big box divided into 15 parts, we know that each of those is
. Check your answer by multiplying
by 5 and you get
which is equal to
.

Answer:
Switch x and y, and solve for y

Step-by-step explanation:
Given

Required
Complete the steps to determine the inverse function
Solving (a): Complete the blanks
Switch x and y, and solve for y
Solving (b): Determine the inverse function
![f(x) = \sqrt[3]{8x} + 4](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Csqrt%5B3%5D%7B8x%7D%20%2B%204)
Replace f(x) with y
![y = \sqrt[3]{8x} + 4](https://tex.z-dn.net/?f=y%20%3D%20%5Csqrt%5B3%5D%7B8x%7D%20%2B%204)
Switch x and y
![x = \sqrt[3]{8y} + 4](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%5B3%5D%7B8y%7D%20%2B%204)
<u>Now, we solve for y</u>
Subtract 4 from both sides
![x -4= \sqrt[3]{8y} + 4-4](https://tex.z-dn.net/?f=x%20-4%3D%20%5Csqrt%5B3%5D%7B8y%7D%20%2B%204-4)
![x -4= \sqrt[3]{8y}](https://tex.z-dn.net/?f=x%20-4%3D%20%5Csqrt%5B3%5D%7B8y%7D)
Take cube roots of both sides

Divide both sides by 8

So, we have:

Hence, the inverse function is:

Answer:
y ≥ 28
Step-by-step explanation:
Isolate the variable. Treat the inequality sign as a equal sign, what you do to one side, you do to the other. Add 6 to both sides:
y - 6 (+6) ≥ 22 (+6)
y ≥ 22 + 6
y ≥ 28
y ≥ 28 is your answer.
