Given the number of calories expended by people with different weights and using different ways of exercising for 20 minute time periods is 120b 150lb 107 136]Bicycling A126 130Jogging 74 85] Walking A 120-pound person and a 150-pound person both bicycle for 40 minutes, jog for 10 minutes, and walk for 60 minutes.

The 120-pound person expended 499 lb and the 150-pound person expended 592 lb.

Step-by-step explanation:

The matrix for number of calories expended by people with different weights and using different ways of exercising for 20 minute time periods is:

It is provided that a 120-pound person and a 150-pound person both bicycle for 40 minutes, jog for 10 minutes, and walk for 60 minutes.

Then the matrix for the number of times the exercises are done is:

Compute the number of calories expended by a 120-pound person and a 150-pound person as follows:

Thus, the 120-pound person expended 499 lb and the 150-pound person expended 592 lb.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
