Answer:
24 pounds
Step-by-step explanation:
Step 1: Find out how many pens he bought
12 pens per pack
Charles bought 60 packs
60 packs x 12 pens = 720 pens
Step 2: Find out how much Charles spent
2.80 per pack
Charles bought 60 packs
60 x 2.80 = 168 pounds
Step 3: Find out how many pens Charles sold
Charles sold 2/3 of his pens
2/3 x 720 = 480
Step 4: Find out how manypens he sold
Charles sold the pens for 40p
40p x 480 = 19200p
Step 5: Convert pences to pounds
19200p = 192 pounds
Step 6: Find the profit
192 - 168 = 24 pounds
Step 7: Therefore statement
Therefore he mad 24 pounds of profit
Answer:
In graph theory and computer science, an adjacency matrix is a square matrix used to represent a finite graph. The elements of the matrix indicate whether pairs of vertices are adjacent or not in the graph.
In the special case of a finite simple graph, the adjacency matrix is a (0,1)-matrix with zeros on its diagonal. If the graph is undirected, the adjacency matrix is symmetric. The relationship between a graph and the eigenvalues and eigenvectors of its adjacency matrix is studied in spectral graph theory.
The adjacency matrix should be distinguished from the incidence matrix for a graph, a different matrix representation whose elements indicate whether vertex–edge pairs are incident or not, and degree matrix which contains information about the degree of each vertex.
