Question

Jenna skateboard ramp is 12 m long and has a height of 5 m . She wants to build a new ramp with the same incline (slope) that is 18 m long. How high should the new ramp be

Answer 1

Answer:

7.5m

Step-by-step explanation:

x1 = 12

y1 = 5

x2 = 18

y2 = ?

m = y / x = 5 / 12

m = y2 / x2

5 / 12 = y2 / 18

12 * y2 = 18 * 5

12 * y2 = 90

y2 = 7.5m
