Answer:
62.41
Step-by-step explanation:
19 7/8= 19.875
C= pie x d
C= 3.14 x 19.875
C= 62.4075
C= 62.41 (if you want 2 decimal places)
 
        
             
        
        
        
Answer:
1/3
Step-by-step explanation:
Alice can select any ball from her bag and it goes into Bob's bag. Then bob has 6 balls including two of one color.
Suppose they are {A,B,B,C,D,E} 
Now Bob must draw one of the two balls of the same color (B) in order to have the same content of the two bags.
P(bags same content)= 2/6= 1/3
The probability that the bags content are the same= 1/3
 
        
             
        
        
        
From the given, it can be seen that the quotient obtained when second term is divided by the first term is equal to 4. This is the same answer when the third term is divided by the second term. Finally, the same quotient when the last term is divided by the third term. This means that the values progress with a common ratio. Thus, the answer is geometric. 
        
                    
             
        
        
        
Answer:
x = 70
y = 40
Step-by-step explanation:
First, we need to find the measure of x.
As x and the angle 110 share a line, they must add up to 180 degrees. This means that the measure of x is 70.
The two ticks on the sides of the triangle indicate that these sides are equal in length. This also means that the corresponding angles will also be equal. This means that both x and the other angle are 70.
This means that we have two of the three angles in the triangle, so we can easily find the third, which is y.
