Answer:
the answer is 445.5
Step-by-step explanation:
what I did was divide 50 by 495 and got 9.9 then since it took 45 minutes every 50 square feet of floor i multiplied 45 x 9.9 and got 445.5
Answer:
8
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
First of all, i mean A and B are out first thing because you don't have enough information to find out if it's true.
C is incorrect because as stated before, not enough information.
<u><em>However,</em></u>
You know that the angles 1-8 are all supplementary, which means that 1 and 2 can be added to make 180 degrees, as so can 3 and 4, 3 and 1. 2 and 4, blah blah blah.
In D, the angles that are being added are supplementary, because the three lines making up that weird figure is adjacent and is parallel to each other.
If you give one of the angles a degree, you know that 180-x with x being that degree, will equal the other angle on the other side of the lines.
Therefore its D.
Edit:
I just realized that theres an angle stated at the top of the screen. Still with that angle given, A and B is incorrect and the answer is still D.
Graph 1: y= -3/4, which means its (x,y) coordinate is (0, -3/4).
Graph 2: y= 3/4, which means its (x,y) coordinate is (0, 3/4).
Graph 1 would be the point -3/4 on the y-axis, while graph 2 would be the point 3/4 on the y-axis.
Therefore, graph 1 and graph 2 are symmetrical about the x-axis.
Hope this would help~
