TOOK THE QUIZ...YOU'RE WELCOME!!!
Answer: 1/6
Explanation:
The question is asking how much of the whole circumference is arc AB given that it's central angle is 60°. We can see that the angle is of the whole. This means that if there were 360 equal sectors, or slices, of the circle, then this angle would take 60 of them.
From this, we can see that if the circumference was divided into 360 equal parts, then the arc would also take up 60 of them, making the arc , or .
We could have alternatively seen that the ratio of arc length to the whole circumference would be the same as the ratio of the central angle to the "whole angle" or 360°.
Putting in 60 for the central angle, we get
The question is asking what fraction of the circumference is the arc length, so let's isolate the arc length by multiplying the circumference to both sides
This equation in words says that the arc length is one sixth of the circumference, which is exactly what the question is asking.

Answer:
True is the correct answer.
Explanation:
Answer:
The answer is C.
Explanation:
Colleges should have no interest in what your parents did, as it isn't necessarily applicable to the path you want to follow. Your employment history is also irrelevant because, again, it's your path. What makes A wrong is that they should have very little interest in your personal life and do not need to know any of your private information (e.g. credit cards, relationships, etcetera). The correct answer is C because you are going to college to pursue a certain career and they must know what it is you want (or plan) to do.
I hope I helped!
