The side view of a ramp that Jessie built for his race cars is shown below. Find r, the length of the ramp to the nearest tenth.

Option B is correct.

The length of the ramp = 15.7 inches

Step-by-step explanation:

The image of the full question is attached to this solution I'll provide.

This is a problem that just requires the application of the Pythagoras theorem.

From the image, the vertical height of the tank is 7 inches.

And the horizontal distance spanned by the ramp = 14 inches.

This all forms a right angled triangle with the length of the ramp as hypotenuse.

Pythagoras theorem, stated mathematically is

(Hyp)² = (Opp)² + (Adj)²

(Hyp)² = 7² + 14²

(Hyp)² = 245

Hyp = 15.65 inches = 15.7 to 1 d.p.

Hence, the length of the ramp = 15.7 inches

Hope this Helps!!!
