Answer: C) Always false

Explanation:
A linear pair of angles satisfy these two requirements (both must be true)
The angles are adjacentThe angles are supplementary, ie they add to 180.While it is possible for vertical angles to be supplementary (they both are 90), it is not possible for vertical angles to be adjacent. This is because vertical angles do not share a common side. Vertical angles are opposite one another, so they are as far from adjacent as possible, while still sharing a common vertex point however.
This means that vertical angles are never considered to be a linear pair. Put another way, you can ask yourself "can vertical angles form a straight line?". The answer is "they can never form a straight line". Again the fact they aren't adjacent is the reason why.

Answer:
It is divided by two each time. They will sell 10 slices of pizza on week 6.
Step-by-step explanation:
Answer:
2, 10, 6
Step-by-step explanation:
160 is half of 320, so that's a divide by 2. 80 is half of 160, so that's also divide by 2. This is the first answer.
Now, we want to know how many weeks until 10 slices are sold in the week. That's the second answer.
To get the third answer, we'll just go down from 80. 80 divided by 2 is 40, so in the 4th week, the cafeteria would sell 40 slices. Divide 40 by 2 and we'll get 20. So, in the fifth week, the cafeteria would sell 20 slices.
20 divided by 2 is 10. That's the sixth week. So, in the sixth week, the cafeteria sells 10 slices. That's the third answer.

What is the surface area of the following triangular prism?
screenshot below :)
a. 24 yd 2
b. 96 yd 2
c. 50 yd 2
d. 90 yd 2
Answer:
The answer is 96 yd 2
Step-by-step explanation:
First for the triangle bases, you multiply the 3 by 4 and divide by 2 to get one base which is 6, then double it to get the other base on the top to get a total of 12. Then you just find the area of the other sides of the prism by multiplying the lengths and widths.
5x7=35
4x7=28
3x7=21
then you add all of the total values together:
35+28+21+12=96
