Answer: Her score at the end of second stage = 30 points
Explanation:
Since we have given that
Danielle started with 10 points
Starting points = 10
In the first round ,
She lost = 20 points
( we will represent it as negative integer as she loses it) .
Now, her score becomes
In the second round,
She won = 20 points

Answer:
65.5 feet per second
Step-by-step explanation:
In order to calculate the rate of descent we first need to find the difference in heigh that the hot air balloon descended. We do this by subtracting the initial height from the end height like so...
6,039 - 3,288 = 2,751 ft
Now that we have the difference in height we need to divide this by 42 since that is the amount of time it took for this descent to occur.
2,751 ft / 42s = 65.5 ft/s
Finally we can see that the rate of descent was 65.5 feet per second
