What is 0.0003124 in scientific notation?
2 answers:
Answer:
3.124*
Step-by-step explanation:
In order to find the scientific notation of a number, you must move the decimal point to the right of the first significant (not 0) number. In this problem, you have to move the decimal 4 points to the right, which means that you would multiply the resulting number by ten to the negative fourth. If you were to move the decimal four points to the left, you would multiply the resulting number by ten to the fourth instead.

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.

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.
