A right triangle has legs measuring 4.5 meters and 1.5 meters. The lenghts of the legs of a second triangle are proportional to
the lengths of the legs of the first triangle. What could be the lengths of the legs of the second triangle? Select each correct pair of lengths
A) 6 m and 2 m
B) 8 m and 5 m
C) 7 m and 3.5 m
D) 10 m and 2.5 m
E) 11.25 m and 3.75 m
We know that in the first triangle the ratio of the legs are 4.5/1.5-----> 3
then case <span>A) 6 m and 2 m ------> ratio=6/3----> 3 so </span><span>the legs of a second triangle are proportional to the lengths of the legs of the first triangle
</span>case B) 8 m and 5 m ------> ratio=8/5---->1.6 so the legs of a second triangle are not proportional to the lengths of the legs of the first triangle
case C) 7 m and 3.5 mm ------> ratio=7/3.5---->2 so the legs of a second triangle are not proportional to the lengths of the legs of the first triangle
case D) 10 m and 2.5 m ------> ratio=10/2.5---->4 so the legs of a second triangle are not proportional to the lengths of the legs of the first triangle
case E) 11.25 m and 3.75 m ------> ratio=11.25/3.75---->3 so the legs of a second triangle are proportional to the lengths of the legs of the first triangle
the answer is A) 6 m and 2 m E) 11.25 m and 3.75 m
well, 6.2% of 4,300 can't be over half. she has made a calculation error, and the real answer is (this is where the mistake was made) 4,300 * 0.062 (not 6.2, because percents are always divided by 100 to make them into a usable number), which is equal to $266.60.
