Question

PLEASE HELP ME FAST !!!

An airplane climbs at a slope of 2/5 at takeoff. At point A, the plane is 200 feet above the ground. The plane traveled 1,000 feet horizontally, as shown in the diagram below. What is the altitude of the plane (b) at Point B?

A) 600 ft.

B) 2,500 ft.

C) 200 ft.

D) 400 ft.

2) Victor is planning on renting a truck from Lowe's. It costs $19 for 90 minutes plus $5 for every 15 minutes thereafter or he could rent the truck all day for $89. How many minutes would Victor need to use the truck in order for the all day rental to be the better deal?

A) 305 minutes

B) 275 minutes

C) 165 minutes

D) 220 minutes

Thank you for your help :)

Answer 1

Given:

Slope of 2/5 at takeoff.

Point A: 200 feet
Distance from point A to point B = 1,000 feet horizontally

First, illustrate the problem. Mark Point A, then mark point B 1000 feet to the right of point A. Draw a 2/5 slope line from ground to point A. Then label line from point A to the ground with 200 feet. Now, we have a triangle. Solve for the altitude of B by comparison.
