The graph shows the relationship between the number of minutes Maria spent jogging on a treadmill and the distance she jogged.

A graph titled Miles on the Treadmill. The x-axis shows number of minutes, numbered 5 to 45, and the y-axis shows distance in miles, numbered 1 to 9. A straight line with a positive slope begins at point (0, 0) and ends at point (45, 4.5).
What was her speed?

  0.1 miles per minute

Step-by-step explanation:

The line goes through (0, 0), so Maria's speed is the ratio of miles to minutes:

  (4.5 mi)/(45 min) = 0.1 mi/min

65°

step-by-step explanation:

the total measure of a triangle is 180 degrees. 62 + 53 is 115.

180 - 115 = 65

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
