I NEED HELP PLEASE! The approach ramp used by a daredevil motorcyclist for flying over a pit of venomous snakes has a rise of 52 feet for every 80 feet in horizontal distance. Find the grade of the ramp. Round to the nearest whole percent.

Answer:

65%

Explanation:

The formula for the grade of the ramp = Rise of the ramp/ horizontal distance of the ramp

Rise of the ramp = 52 feet

Horizontal distance = 80 feet

Grade of the ramp = 52 feet/80 feet

= 0.65

The grade of the ramp is 0.65

Rounding up to the nearest whole percent

Grade of the ramp = 0.65 × 100

= 65%

Therefore, the grade of the ramp to the nearest whole percent = 65%
