Answer:
9 in²
 in²
Step-by-step explanation:
The area (A) of an equilateral triangle is calculated as
A =  ( s is the length of a side )
 ( s is the length of a side )
Here s = 6, thus
A =  =
 =  = 9
 = 9 in²
 in²
 
        
             
        
        
        
3, 12, 15, 25, 30, 40The range is the difference between the greatest and smallest values:
range = 40 - 3 = 37
Thee average is the sum of elements divided by the number of elements:
average = (<span>3 + 12 + 15 + 25 + 30 + 40</span>)/6
average = 125/6 = 20.83
        
             
        
        
        
Answer:
2.5 pi
Step-by-step explanation:
Comment
If you were trying to get the area of a whole circle, you would use 
Area = pi r^2
You have to modify the formula to show that just part of the circle has an area that you are interested in.
The new formula is
Area = (theta/360) pi r^2
Givens
r = 30 cm
theta = 100 
Solution
Area = (100 / 360) * pi * r^2       Substitute the givens into this formula
Area = (5 / 18) * pi * 3^2              Expand
Area = (5 / 18) * pi * 9                  Cancel 9 into 18
Area = 5/2 * pi
Area = 2.5 * pi
 
        
             
        
        
        
Answer: P * ( 1 + 7%)
Step-by-step explanation:
You included no options but the expression should go something like this:
Pn = P * ( 1 + 7%)
Where Pn is the new price
P is the current price
<em>The above formula will show the new price given the current price. </em>
 
        
             
        
        
        
Answer:
Not proportional.
Step-by-step explanation:
The values do not begin from a straight line at the origin. X begins at 2, not the origin.
