He has $4.40, the quarters, nickels, and dimes added up to $1.80, subtract that from $6.20 and you get $4.40

The other form of circle equation is (x-a)2 + (y-b)2 = r2. a and b is the coordinate of the center and r is radius. So the equation is x2+(y-4)2=9. Change it to the general form is x2+y2-8y+7=0. So A=1, B=1, C=0, D=-8 and E=7.
        
                    
             
        
        
        
Triangle Area = .5 * (base * height)
36 = (base * height) / 2
So let's say base = 9 height 8
If base and height are scaled by a factor if 5 than
base = 45 height 40 and 
area = .5 * (45 * 40)
area = 900
Basically, the area increases by a factor of 25.
The base increases by 5 and the height increases by 5 so the area increases by 5*5 = 25
        
             
        
        
        
Answer:
95 degrees.
Step-by-step explanation:
Their sum is 180. You will subtract 85 to get the other half of the whole.
180 - 85 = 95
The other angle is 95 degrees.
