The local school sponsored a mini-marathon and supplied 40 gallons of water per hour for the runners. what is the amount of water in quarts per hour? 10 qt/h 160 qt/h 320 qt/h 80 qt/h

it happens during combustion and impacts the environment because the plants and trees take in that and it can cause them to die.

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
