Angle QPS is an inscribed angle. Arc QS is the intercepted arc of that angle. The rule is that the intercepted arc is twice its angle measure. P measures 20 degrees, so arc QS measures 40 degrees. It just so happens that angle QTS is ALSO an inscribed angle intercepting arc QS. So angle QTS measures the same as angle P, 20 degrees. That's a. For b., we already stated the rule and figured out that minor arc QS is 40 degrees. For c., major arc QTS is 360 (the measure around the outside of a circle...EVERY circle in the world) minus the minor arc of 40. So major arc QTS measures 360 - 40 which is 320 degrees. There you go!
Her equation doesn't fit the word problem! It says several 2 pounds books but she put it as if there was one. She should have wrote the equation like this:
3 + 2x = 20 (where x represents the unknown amount of boxes)
and than you can just solve for x to find how many books there are
3 + 2x = 20
2x = 20
x = 10
So there are 10 books!
I hope that helps! Let me know if you have any questions :3
Answer:
15/5 or 3
Step-by-step explanation:
After 75% increase followed by a 33 1/2% decrease the net increased is 16.375%.
<u>Solution:</u>
Need to determine net percentage increase or decrease when a value is increased by 75% and then decreased by 
that is 33.5%.
Let’s assume initial value be represented by variable x.
Now there is decrease of 33.5%
Hence after 75% increase followed by a decrease the net increased is 16.375%.
