An object travels 60 miles in 1/2 hour. How many miles does the object
travel in 6 hours

720

Step-by-step explanation:

720

Step-by-step explanation:

There are two 1/2 miles in a mile. this means there are 12 half miles in 6 miles. So take 60*12 to get 720.

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

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
