Sea level would be 0
So if it is going -12 /ft/s then it is descending 12 feet per second
-120/-12 = 10
The correct answer would be 10 seconds
I hope this helps!
Answer:
X=22
Step-by-step explanation:
All the angles in every triangle must add up to 180 so we can subtract 23 and 135 from 180 to get 22.
If the original investment doubled in 10 years, then double the investment
will double again in the next 10 years. Thus, in <u>20 years</u>, the original sum
would have increased fourfold.
