4 0

Answer:

400%

Step-by-step explanation:

We can write a percent proportion:

600/x = 150/100

a:b = c:d

a and d are linked and b and c are linked. So if a is missing, you would do (b*c)/d to get a, if b was missing, you would do (a*d)/c to get b, etc.

So over here we do

(600*100)/150 = 60,000/150 = 400, so x = 400, so that means it's 400% of 150

We can also use benchmark fractions which I find much easier:

100% of 150 is 150.

So 200% of 150 is 300

So 300% of 150 is 450

And 400% of 140 is 600

Every time it increases by 100%, it also increases by 150 on the other side, which makes sense

Let me know if you have any questions.

Answer: D) 300 degrees (counterclockwise)

================================================

We want to have segment PQ rotate around the center so that it lines up with segment RF. Put another way: we want point P to rotate around the center to have it line up with point R, and we want Q to rotate so that it moves to point F.

Going clockwise, this is a rotation of 60 degrees as the diagram below shows (each blue arc is 30 degrees, so in total it's 30+30 = 60). In that diagram, I'm only focusing on moving point P. Point Q moves in a similar fashion. Since 60 is not an answer, this means 360-60 = 300 must be the answer.
