A class has 19 girls and 7 boys. Each student receives 14 tickets to exchange for class prizes. create and equation to show how my total tickets the students

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

the furthest the dog can be is 508 meters away from the house, and the closest he can be is 492 meters away from the house.

my computer is slow i can not see it sorry
