Answer:
A: 77
Step-by-step explanation:
360 - 109 - 137 - 37 = 77
Answer:
0.31
Step-by-step explanation:
So if you divide 31 by 100 all you have to do is move the decimal from right to left the number of zeros you have. Here we have 2 zeros so we move from right to left twice.
0.31
The number of edges can be calculated from the number of vertices.
- <em>There are 14 vertices for 105 edges</em>
- <em>There are 200 vertices for 19900 edges</em>
The variable N is used to always represent the number of vertices.
So, we represent the edges as:

<u />
<u>(a) The value of N for 105 edges</u>
The relationship between N and E is:

Substitute 105 for E

Multiply through by 2


Rewrite as:

Expand

Factorize

Factor out N + 14

Solve for N
or 
The number of vertices (N) cannot be negative. So:

<u>(b) The value of N for 19900 edges</u>
We have:

Substitute 19900 for E

Multiply through by 2


Rewrite as:

Expand

Factorize

Factor out N + 199

Solve for N
or 
The number of vertices (N) cannot be negative. So:

<em>Hence, there are 200 vertices for 19900 edges</em>
