Problem 7)
The answer is choice B. Only graph 2 contains an Euler circuit.
-----------------
To have a Euler circuit, each vertex must have an even number of paths connecting to it. This does not happen with graph 1 since vertex A and vertex D have an odd number of vertices (3 each). The odd vertex count makes it impossible to travel back to the starting point, while making sure to only use each edge one time only.
With graph 2, each vertex has exactly two edges attached to it. So an Euler circuit is possible here.

Problem 8)
The answer is choice B) 5
-----------------
Work Shown:
abc base 2 = (a*2^2 + b*2^1 + c*2^0) base 10
101 base 2 = (1*2^2 + 0*2^1 + 1*2^0) base 10
101 base 2 = (1*4 + 0*2 + 1*1) base 10
101 base 2 = (4 + 0 + 1) base 10
101 base 2 = 5 base 10
Answer: there are 8 cars. Each car has 4 tires. How many tires are there in all?
In this case you’ll have to do 8 x 4 because there are 8 cars and to know how many tires you’ll have to count 4 times the number of cars, 8.
Hope this helped and pls mark as brainliest!

Answer:
96 feet
Step-by-step explanation:
This problem requires the use of pythagorean theorem.
she walks 24 ft south + 32 ft east + 
= 56 + 
Answer: 19
Step-by-step explanation:
79 - y = 2y + 22
2y + y = 79 - 22
3y = 57
y = 19
I hope I helped you.
