The height at the top of a roller coaster hill is $10$ times the height $h$ of the starting point. the height decreases $100$ feet from the top to the bottom of the hill. the height at the bottom of the hill is $-10$ feet. find $h$ .

h = 9 feet.

Step-by-step explanation:

The height at the top of a roller coaster hill is 10 times the height h feet of the starting point. The height decreases 100 feet from the top to the bottom of the hill. The height at the bottom of the hill is -10 feet.

Therefore, there is a zero elevation point between the starting point at h height and the bottom of the hill which is at - 10 feet from the zero elevation point.

Now, the elevation of the top of the hill from the zero elevation point is (100 - 10) = 90 feet.

Therefore, 10h = 90

⇒ h = 9 feet. (Answer)

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
