<span>Example: 56.25%/100 = .5625, Next, count the number of digits to the right of the decimal point, say that number is n, and multiply and divide the decimal by 10^n. For your example n = 4 so multiply and divide the decimal by 10^4, which is 10000, giving 5625/10000 which is the fraction sought. This last operation converts the decimal fraction to a whole number needed for the numerator of the fraction. </span>
        
                    
             
        
        
        
Answer:
-1/2
Step-by-step explanation:
cos(x+pi) = -cos(x), so the answer is -1/2.
 
        
             
        
        
        
Answer:
An equation modeling the situation  is : 4 m + 6 n  = 180
Step-by-step explanation:
Here,  the total number of guests in the banquet hall = 180
Let us assume number of tables ordered  with capacity of
 4 people each  = m
And number of tables ordered  with capacity of 6 people each  = n
So, total number of people in m tables = m x ( Capacity of 1 table) 
=  m x (4)  = 4 m 
And, total number of people in n tables = n x ( Capacity of 1 table) 
=  n x (6)  = 6 n
So, the total capacity of ( m + n) tables  = 4 m + 6 n
Also, the total required capacity  = 180
⇒  4 m + 6 n  = 180
Hence, an equation modeling the situation  is : 4 m + 6 n  = 180
 
        
             
        
        
        
11/50=1.1/5=0.22
They are indeed equivalent.
        
             
        
        
        
The answer is D. This is because all of the variables must be on one side so it can be factored.
