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:
C
Step-by-step explanation:
the square root of 1/4 is 0.5 which is positive, rational, and between 0 and 1
The two quadrilaterals are similar. Which means the ratios of respective sides of two quadrilaterals will be the same.
So, for the given quadrilaterals, ratio of sides JF and TF of quadrilateral RJFT will be equal to the ratio of sides YP and AP of quadrilateral SYPA. Mathematically, we can write:
So the measure of TF will be 96mm
<u>Answer:</u>
<u>Step-by-step explanation:</u>
We are given the following equation and we are supposed to solve y in terms of x. It simpler terms, it means that we have to make y the subject of the equation while x being used in it as it is:
Taking the constant 4 to the side where x is to get:
Multiplying the denominator 3 to the other side of the equation to get:
Isolating y to make it the subject:
4 * 45 = 180
265 - 180 = 85
85/5 = 17
