PLEASE HELP ASAP A phone company offers two monthly plans. Plan A costs $19 plus an additional $0.12 for each minute of calls. Plan B costs $11 plus an additional $0.16 for
each minute of calls.
For what amount of calling do the two plans cost the
same?
minutes
What is the cost when the two plans cost the same?

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

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"
