Slope =(y2-y1)/(x2-x1)
=(-4-5)/(-2-3)
=-9/-5
=9/5
How many times do 15 minutes fit into one hour? 4 times: 4*15=60 mins.
So that means that 4 times per hour 10 flights appear, and in total 4*10=40 planes arrive over one hour!
The polygon has 18 sides. To find an exterior angle you have to divide 360 by the number of sides in the polygon to find the measure of an exterior angle. Since each exterior angle equals 20 degrees, you would divide 360 by 20 which would equal 18 sides.
Answer:
1. First subtract initial $2.50 fee
$32.50 - $2.50 = $30.00
2. $30 / $2 = 15 miles
Check...
1. Mile 1 (fee + 1 mile charge)
$2.50 + $2.00 = $4.50
2. Miles 2-15 (14 additional miles)
$2.00 * 14 = $28.00
Total: $4.50 + 28.00 = $32.50
