Answer:
5)  35 / 100 = X / 74      X = 2590 / 100 = 25.9
or .35 * 74 = 25.9
6) 78 / 95 = X * 100
X = 7800 / 95 = 82.1 %
or X = 78/95 * 100 = 82.1 %
7)  60/100 * X = 28
X = 2800 / 60 = 46.7
Or .6 * X = 28
X = .28 / .6 = 46.7
 
        
             
        
        
        
Answer: 7.1 yd
Step-by-step explanation:
the formula for arc length is 2πr(x/360),  x being the central angle
input the values, so the equation would be 2π9(45/360), which equals 7.1
