Answer:
the length of the ramp is 25 meters
Step-by-step explanation:
Joe is making a ramp. Ramp forms a right angle triangle with the base
So we use Pythagorean theorem to find the length of the ramp
AC^2(hypotenuse) = AB^2 + BC^2
Length of ramp is the hypotenuse = 
=
= 
= 
= 25
so the length of the ramp is 25 meters
The cheaper car service would be the second option, $10 upfront + $.05 per mile.
$4+$.70(12 miles)= $12.40
$10=$.05(12 miles)= $10.60
Hope this helps you! :D
