AC= √CD^2+AD^2
AC= √AB^2+BC^2
Those two are true

The area of a circle is area = pi x r^2
The full area = 3.14 x 20^2 = 1256 square feet.
The corner forms a 90 degree angle so the dirt area is 3/4 of a full circle.
Answer = 1256 x 3/4 = 942 square feet 
 
        
                    
             
        
        
        
Circumference = πD 
30π = πD 
D = 30 inches
Answer: 30 inches
        
                    
             
        
        
        
To solve the inequality, you need to isolate/get x by itself:
171 > -6x    Divide -6 on both sides [dividing/multiplying a negative number on
-28.5 < x       [dividing/multiplying a negative number in an inequality causes the sign (<, >, ≤, ≥) to flip]
-28.5 < x    [x is a number greater than -28.5]
So your graph should have an open circle at -28.5 (the first small line next to -28), and the arrow pointing to the right since x is greater than -28.5 (increasing)      The 1st option is your answer
[use the o---> and put it at -28.5]
 
        
             
        
        
        
Answer:
Early college provides high school students the ability to get a sneak-peak into what college is like as a whole. Credits, professors, homework, campus and friends don't need to be intimidating topics anymore.
