Answer: The girl herself ran faster than her friend.
Step-by-step explanation:
This answer, of course assumes a lot of variables, but for the sake of keeping things simple, lets assume the following, the people are ran in a "straight line" with no "obstacles" in their way, and ran on the same track.
Calculating in meters-per-second for the girl who ran 200 meters in 28 seconds, you get 7.14285714286 meters per second
Calculating in meters-per-second for the girl who ran 400 meters in 60 seconds, you get 6.66666666667 meters per second
Comparing the two results, it can be "accurately" concluded that the girl herself ran faster than her friend under the following assumptions earlier stated.
Answer:
21/4
Step-by-step explanation:
21 y = -4x Divide 21 on both sides
y = -4/21x Slope is -4/21
Perpendictulare lines have a slope that are the negative inverses of eachother, so flip the 4 and the 21 and make it positve instead of negative
Answer:
The scale factor for dilation can be worked out from the ratio of sides.
Here, for i.e, I'H'/IH = (8 + 4)/(4 + 2) = 12/6 = 2
Hope this helps!
