Step-by-step explanation:
I know this is rather sneaky, but on a multiple choice question on a quiz, you need all the help you can get. I'm not saying this is a quiz, by the way. It doesn't say that it is anywhere.
Look carefully at the first three statements. Is there an angle mentioned at all? There isn't, is there? That being the case (and since nothing is marked as a right angle), the only possible answer is SSS which D.
Answer:
skew
Step-by-step explanation:
Perpendicular lines must intersect. In fact, they intersect forming right angles.
Lines AC and RC are not in the same plane and do not intersect.
They are called "skew lines."
Answer:
13.1666666667 or 13.17
Step-by-step explanation:
The mean is the average of the numbers. So you should add 16, 12, 16, 8, 14, and 13. When you add all of these up, you get 79. Then, you divide 79 by the number of numbers there are. Since there are 6 cats, there are 6 numbers. 79 divided by 6 equals 13.1666666667. Now we round the number to the nearest tenth and we will get 13.17.
Because the denominator (bottom number) of the fraction tells you
how many equal pieces the whole thing has been cut up into.
When you cut up the whole thing into 6 pieces, each piece is bigger
than if you cut it into 8 pieces, but less than if you cut it into 3 pieces.
