Answer:
5 ft
Step-by-step explanation:
The triangular face is a right triangle with hypotenuse 13 ft
Use Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
y² + 12² = 13²
y² + 144 = 169 ( subtract 144 from both sides )
y² = 25 ( take the square root of both sides )
y = = 5
The height of the ramp is 5 ft

Answer:
260m
$73.2
Step-by-step explanation:
For what amount of driving do the plans cost the same?
What the cost when the two plans cost the same?
first plan = 42 + 0.12m
second plan = 55 + 0.07m
42 + 0.12m = 55 + 0.07m
collect like terms
55 - 42 = 0.12 - 0.07m
13 = 0.05m
m = 260
42 + 0.12(260) = 73.2
