For this case we have the following numbers:
 299
 388
 Let's round up each of the numbers to the nearest hundred,
 We have then:
 299 = 300
 388 = 400
 We note that now we have two numbers whose approximation is easier to add.
 We have then:
 300 + 400 = 700
 Answer:
 The sum of 299 + 388 is approximately:
 700
 
        
                    
             
        
        
        
The answer is "A. greater than" because if the number of edges increase, the measure of each exterior angle increases too!
Hope this helps. :)
        
                    
             
        
        
        
Answer:
781250
Step-by-step explanation:
We first need to find the common ratio
-10 /2 = -5
50 / -10 = -5
The common ratio is -5
an = a (r) ^ (n-1)
a9 = 2 ( -5) ^(9-1)
      = 2 (-5)^8
       =781250
 
        
             
        
        
        
She has 67% of the pencils. 
Chester:Mary = 2:4 = 1:2
So, in the simplest case:
If Chester has one pencil Mary would have two. 
There are three pencils. 
Mary has two. 
2/3 = 0.667 = 67% (rounded)
