75 and 100.
It is 25% lesser because if you subtract 75 and 100 from each other, you get 25.
The computation shows that the change in points is 89 3/4 points.
<h3>How to compute the value?</h3>
From the information, at the beginning of the day the stock market goes down 30 3/4 points and stays at this level for most of the day and at the end the stock market goes up 120 1/2 points.
Therefore, the change will be:
= 120 1/2 - 30 3/4
= 89 3/4

The sum of the angles of an n-sided polygon is (n-2)×180°
For a 30-gon, it would be 28x180 = 5040, answer B
Second question is more of a trick question. Exterior angles always add up to 360. So answer H.
Answer
A. Slope of the graph
Step-by-step explanation:
I got the answer cause I just took the test
This question is worded badly, so don't be alarmed.
Obviously if this were a square patter the number of red tiles could only be 1,4,9,16,25,36 etc and this is not the numbers given...It would help tremendously if they gave you another reference point so as to know how the tiles were being laid out.
If they are laid out alongside one another with a consistent border for each you wouldn't need 12 blue tiles for each red tile either...if two were laid side by side you would only need 20 blue tiles to have the border around both...you see how the arrangement makes a huge difference and you are given no details as to what that arrangement is...
So just to keep it simple, assume that each red tile is surrounded by 12 blue tiles....
Total tiles equals r+12r=13r
t=13r so
t(15)=195, t(20)=260, t(25)=325, t(30)=390
