Which situation describes opposite quantities that when combined would equal 0?
A. A plane ascends to 15000 feet and then descends 15000 feet. How many feet above the ground is the plane?
B. A plane ascends to 15000 feet and then descends 10000 feet. How many feet above the ground is the plane?
C. A plane ascends to 15000 feet and ascends 15000 feet. How many feet above the ground is the plane?
D. A plane ascends to 10000 feet and ascends 15000 feet. How many feet above the ground is the plane?
A. A plane ascends to 15000 feet and then descends 15000 feet. How many feet above the ground is the plane?
The answer is 0.
The situation that describes opposite quantities that when combined would equal 0 is option A: A plane ascends to 15000 feet and then descends 15000 feet. In this situation, the plane's altitude would be 0 feet above the ground.
The situation that describes opposite quantities that, when combined, would equal 0 is option A: A plane ascends to 15000 feet and then descends 15000 feet.
To determine the number of feet above the ground in this situation, we can subtract the descent distance from the ascent distance.
So, if the plane ascends to 15000 feet and then descends 15000 feet, the calculation would be: 15000 - 15000 = 0. This means that the plane would be at the same altitude as the ground level.
