Answer: 16
Step-by-step explanation:
For the first question, it would be D:

÷ 9. This is because to solve a division problem with fractions, you would need to multiply the first fraction by the reciprocal of the second fraction. For the second question, the answer would be D: 32. This can be solved by dividing 8 by

or 0.25. For the third question, it would be D.

. This can be solved by dividing

by 3. For the fourth question, the answer would be

. This can be found by flipping the 4, which would make it look like

, and multiplying it by

. For the last question, 1 would be B, 2 would be C, 3 would be C, and 4 would be A.
Hope this helps ^-^
The numbers that are divisible by 1 and the number itself is called a prime number. Eg: 1,2,3,5,7,11,13,17,19
Answer:

Step-by-step explanation:
I will assume the following:
- You know how to use the quadratic formula
- You know how to simplify radicals
- You know how to use the pythagorean theorem.
The challenge of this exercise comes from using the pythagorean theorem and setting up a few equations.
Given that we have a segment 36 units long and another segment that is 16, it is trivial to get the other segment, 20. Additionally, there are two sides that I want to name so that way I can make a couple of substitutions. I will call these side a and side b. (see attachment 1)
Now comes with setting up three equations. I will start with the two smaller triangles, using side a and side b. See attachments 2 and 3.
Now with the big triangle. I will set up one last equation. See attachment 4.
Given what we know about attachment 2 and 3, we can make two substitutions. See attachment 5. I assume you know how to do the rest and arrive at your only real solution.
