B. 1 and 5 are factors of all three numbers :)
        
             
        
        
        
Answer:
13
Step-by-step explanation:
We know that a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse
5^2 + 12^2 = c^2
25+144 = c^2
169 = c^2
Taking the square root of each side
sqrt(169) = sqrt(c^2)
13 =c
 
        
             
        
        
        
Answer:
C
Step-by-step explanation:
First of all their is an easier way solving this 2l/ + l^2
but how you need it is c because the base is 100 and each face is 40 how 10x8=80 80/2=40 
 
        
             
        
        
        
Answer:
8
Step-by-step explanation:
10^2=100 6^2=36 100-36=64 sqrt64=8
 
        
             
        
        
        
The probability of drawing a 5 from card numbered 1 - 10 is 1/10 because only one card out of ten is numbered 5. 
The probability of rolling a 2 on the cube is 1/6 because there are 6 faces of the cube with 6 different numbers. The probability of picking a 5 and rolling a 2 together is 1/60 because 
1/10 x 1/6 = 1/60. You multiply them together because there will be 60 combinations: 10 card possibilities and 6 cube possibilities. 
Hope this helps!
