Answer:
75.44 Square Inches
Step-by-step explanation:
The diagram of the problem is produced and attached.
To determine the area of the cleaned sector:
Let the radius of the larger sector be R
Let the radius of the smaller sector be r
Area of the larger sector 
Area of the smaller sector 
Area of shaded part =Area of the larger sector-Area of the smaller sector

From the diagram, R=10 Inch, r=10-7=3 Inch, 
Therefore, Area of the sector cleaned 
 
 
        
             
        
        
        
Answer:
C=x+200
the y intercept is 200.
the y intercept represents $200 after 0 phones
 
        
             
        
        
        
Answer:
x^0 y^-3 / x^2 y^-1  
= 1 /  x^2 y^-1 (y^3)  ...because  x^0 = 1 and  [(y^-1) (y^3)] = y^2
= 1/(x^2 y^2)
 
        
             
        
        
        
Answer: C
Step-by-step explanation:
Supplementary angles add up to 180
x + 83 = 180
x= 97
