Answer:
80%
Step-by-step explanation:
To find percentage increase, we use the following formula:
Percentage Increase = 
Here
New means the latest value (which is 18 dancers)
Old means the previous value (which is 10 dancers)
The Multiplication by 100 is to convert the decimal answer to percentage.
So, we have:
New = 18
Old = 10
Now we substitute and find:

So, there was an increase of 80%
Answer:
The slope is 3 and the line is rising.
Step-by-step explanation:
To find the slope m of a line given two points (x₁, y₁) and (x₂,y₂) we can use the formula:
m = (y₂-y₁) / (x₂ - x₁)
In this problem we have the points (6,2) and (7,5), substituting these values in the formula we get:
m = (5 - 2) / (7 - 6) = 3/1 = 3
Therefore, the slope is 3.
Given that the slope is positive we can conclude that the line through the points rises.
Let the distance of Jill form the base of the tower be x, then tan 40 = 100/x
x = 100/tan 40 = 100/0.8391 = 119.18 meters
Let the height of the tower from the level of the top of Jill's apartment be y, then tan 30 = y/119.18
y = 119.18 x tan 30 = 68.8 meters
Therefore, the height of Jill's apartment is 100 - 68.8 = 31.2 meters
