A roller coaster begins at 90 feet above ground level. Then it descends 105 feet. Which statement correctly finds the height of the coaster after the first descent?
90 + 105 = 195
90 - 105 = -195
105 - 90 = 15
90 - 105 = -15
The correct statement is 90 - 105 = -15. After the first descent, the height of the coaster would be 15 feet below ground level.
To find the height of the coaster after the first descent, we need to subtract the distance it descends from its starting height of 90 feet.
So the correct statement is:
90 - 105 = -15.
Therefore, the height of the coaster after the first descent is -15 feet.
To find the height of the roller coaster after the first descent, you need to determine the net change in height. Since the coaster descends 105 feet from its initial height of 90 feet, you need to subtract 105 from 90.
So, the correct statement is:
90 - 105 = -15
Therefore, the height of the coaster after the first descent is -15 feet.
