The amount of hours lance spent training for the cycling race was increased from 60
miles a day to 90 miles a day. by what percentage did lance's training hours
increases

i think its 150 percent

Step-by-step explanation:

cause 90/60 is 1.5 then move the decimal over 2 and get 150.

"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.
