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.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

answer: howdy
