One week a student exercised 2 hours at school and 2/3 hour at home. If 1/4 of the student's total exercise came from playing basketball, how much time did the student spend playing basketball that week?

The student played basketball for 40 minutes.

Step-by-step explanation:

Given that one week a student exercised for 2 hours at school and for 2/3 of an hour at home, it can be stated that the student exercised for 2 hours and 40 minutes (since 60 x 2/3 is equal to 40 ). Thus, in total the boy exercised for 160 minutes (2 x 60 + 40).

Now, since he spent 1/4 of that time playing basketball, the time spent doing this sport is determined through the following calculation:

160/4 = X

40 = X

Thus, the student played basketball for 40 minutes.

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!
