Mr. Gubareff gave his class 15 minutes to read. Sabira read 6 ¼ pages in that time. At what rate, in pages per hour, did Sabira read?

I think its 25 (proceed with caution)

Step-by-step explanation:

15×4=60 so basically 6.25×4=25

6.25 = 6 1/4

I believe the answer is 25 pages per hour

Step-by-step explanation:

A will represent “answer”

15 x 4 = 60

so

6 1/4 x 4 = a

6 1/4 x 4 = 25

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

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
