If a bakery produces 1,215 cupcakes during a 9 hour shift, what is the production rate of cupcakes per hour?​

135

Step-by-step explanation:

135 cupcakes

Step-by-step explanation:

You would do 1,215 divided by 9 to get your answer. So the answer would be 135 cupcakes.

the size of the resulting matrix is 1-by-3.

step-by-step explanation:

the size of the two matrices given are as follows:

no .of rows of matrix 1 = 1

no .of columns of matrix 1 = 3

no .of rows of matrix 1 = 3

no .of columns of matrix 1 = 3

to find the size of the resulting matrix without actually solving the multiplication of the matrix, this is what you do:

if resulting matrix = matrix 1 * matrix 2

no. of rows of the resulting matrix = number of rows of matrix 1

no. of columns of resulting matrix = number of columns of matrix 2

note: the order of the matrices matter!
