A ramp is 10 feet in length. The ramp is lifted 4 feet off the ground to the truck door. What is the distance across the ground from the bottom of the ramp to the ground underneath the truck door? Approximate to the nearest hundredth.

The ramp is the hypotenuse of a right triangle, with length 10 feet and vertical height 4 feet. By the Pythagorean theorem, the ground distance is √(10² − 4²) = √84 ≈ 9.17 feet. The correct choice is approximately 9.17 feet.
