Answer: a $0.23
explanation: 2.76 divided by 12 is 0.23
to check: 0.23 X 12 = 2.76
We know that he takes 10 quizzes per 2 weeks
That means we need to add 10+10+10+10=40 quizzes and 2+2+2+2=8 weeks
But were not done! Half of 10 = 5 so that means it will take 1 week to take 5 quizzes
8+1=9
It will take him 9 weeks to take 45 quizzes
Hope this helped!

Step-by-step explanation:
Remark
No wonder you are posting this. You should never have to rely on a diagram to get an answer, and this diagram is particularly unreliable. What exactly does the peak mean? Does it tell you that the peak is both y and 20 degrees? I'm going to assume so. But it is a very shakey assumption.
Pick a triangle with 2 ys in it. The third angle hits one of the sides of the triangle. Every triangle has 180 degrees. The top angle is 20 degrees and all ys therefor are 20 degrees. So the third angle is y + y + x =180
The 2xs are in a quadrilateral near the top. All quadrilaterals have 360 degrees. q and one of the angles are vertically opposite. q is then known.
Givens
y = 20
third angle = x
solution
<u><em>triangles with 2 ys (isosceles)</em></u>
y + y + x = 180
2y + x = 180
y = 20
2*20 + x = 180
40 + x = 180
x = 140
<u><em>Quadrillateral</em></u>
140 + 140 + 20 + vertically opposite q = 360
300 + vertically opposite q = 360
vertically opposite q = 360 - 300
vertically opposite q = 60
Answer
q = 60
Answer:
+1, -1, +11, -11
probably written with a +- symbol:
+-1, +-11
Maybe (silly) written like fractions:
+- 1/1, +- 11/1
Step-by-step explanation:
First list the factors of the leading coefficient. Here its 1. So we're going to use positive and negatives of the factors of 1, which is just +/- 1 . These numbers are going to go on the bottom of a fraction.
Next look for the factors of the constant, here it's 11
So that gives us
+/- 1, +/- 11 . These will go on the top of a fraction. (A fraction is a rational expression, that's why the name)
Then make all the combinations of
factors of constant
OVER
factors of leadingcoeff
So, we find
+/- 1, +/- 11
