12 km
Step-by-step explanation:
0.10 km = 1 minute
X = 120 minutes
(0.10)*(120) = 12
First of all I want to point out you drew the diagram a little wrong. The Arc is 41 doesn't mean its 41 degrees it means it has length 41 so remove the degrees symbol.
Now for the answer the other arc have to have angle 40 too because vertical angles. And because the radius is the same, both of the length has formula 40/360*pi*2*radius which is 41 in this case. So x has to be 41 also :) Done!
Z would mean 0 considering they would both be the last
$180 for 6 months
Why: Well the equation is " y = 25x + 30 " where x represents the months. First you do 25 x 6 because the equation says $25 PER MONTH. After that, add the initial fee of $30 giving you the total of $180.
