Question

An airplane descended 4,000 feet before landing. The integer that represents how many feet the airplane was above the ground before it's descent is

Answer 1

Answer:

The required integer is 4,000 or +4,000.

Step-by-step explanation:

Consider the provided information.

It is given that an airplane descended 4,000 feet before landing.

We need to determine the integer which represents how many feet the airplane was above the ground before it's descent is.

Before it's descent, airplane was at the height of 4,000 feet.

if a point is below the ground then we will indicate it by placing a negative sign in the front of the number and if it is above the ground then we will indicate it by placing a positive sign or no sign in the front of the number.

Since, 4,000 feet is the distance of airplane above the ground.

So, the airplane was +4,000 feet above the ground before its descent.

The required integer is 4,000 or +4,000.
