Lines aa, bb, and cc show proportional relationships. which line has a constant of proportionality between yy and xx of \dfrac{5}{4} 4 5 ? ?

All of the ratios between the two quantities can be simplified to 1212, so the quantities are proportional.

The Yes

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"
