you had to the gym for a workout and get on a treadmill you set a goal on the treadmill to burn 300 calories while running at a constant speed the treadmill tells you how many total miles xerun along with the number of calories see you have left to burn at one point during your workout you look at the treadmill screen and it tells you that after running 0.6 miles you have 255 calories left to burn to meet your goal how many calories will you burn after running 1 mile

  75

Step-by-step explanation:

In running 0.6 miles, you have gone from 300 remaining to 255 remaining, so have burned ...

  300 -255 = 45 . . . . . calories

The rate in calories per mile is ...

  (45 cal)/(0.6 mi) = 75 cal/mi

At the rate of the first 0.6 miles, you will burn 75 calories running 1 mile.

the answer is d. 75%

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
