Several times a week, Chuck goes to the gym to run andswim. When running, heburns 35 calories per minute. When swimming, he burns 30 calories per minute. He has found a way to burn 730 calories after exercising for a total of 23 minutes. If r is the number of minutes running and wis the number of minutes swimming, howlong does Chuck spend at each activity?

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

40 minutes

step-by-step explanation:

add the time and multiply by 2

the answer is 48m^2!

step-by-step explanation:

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
