Answer:
The correct option is A.
Step-by-step explanation:
If a graph is formed by connecting a single universal vertex to all vertices of a cycle, then it is known as wheel graph.
W₆ means wheel graph having 6 vertices as shown in the below figure.
Total number of edges in a wheel graph is 2(n-1), where n is number of vertices. So, the number of edges in W₆ is
In a spanning tree all the vertices covered with minimum possible number of edges. Total number of edges in a spanning tree is (n-1).
Total number of edges in a spanning tree which has 6 vertices is
The number of edges we need to remove is
Therefore the correct option is A.
Answer:
if your number is 1000 there should be one decimal at the end so it should be 1000. Because 1000. And 1000 are the same thing

Answer:
52 miles/week (12 more miles per week)
Step-by-step explanation:
In order to know the miles per week with this increasement, we'll use the rule of 3, assuming that 40 miles is the 100% innitially so:
If:
40 miles --------->100%
X miles ----------> 30%
Solving for X we have the following:
X = 30 * 40 / 100 = 12 miles
So, if Adam wants to increase his weekly mileage by 30%, he needs to run 12 more miles, and that makes a total of 52 miles/week
