Answer:
Janet has coins worth 252.5, 101, and 50.5. 
Step-by-step explanation:
Let us call the three coins  , and
, and  .
. 
The first coin  is 5 times another coin<em> (let's say </em>
 is 5 times another coin<em> (let's say </em> ); therefore,
); therefore, 
 ,
, 
and the third coin is 2 times the value of another coin<em> (it's coin </em> <em>):</em>
<em>):</em>
<em /> <em>.</em>
<em>.</em>
The total worth of all coins is 404; therefore, 

or 



with the value of  in hand, we find
 in hand, we find  and
 and  :
: 


and for 


Thus, Janet has 3 coins worth 252.5, 101, and 50.5. 
 
        
             
        
        
        
The answer is 2:1.
The centroid separates the median, or the point from the midpoint of a side of a triangle with its opposite angle, at a ratio of 2:1, meaning that one segment is 1/3 the length of the median and the other segment is 2/3 the length of the median. 
        
             
        
        
        
Answer:
Step-by-step explanation:
Its like doing a long division with base 10 numbers:
            1110    <----------- Quotient
101)1001010
         101
          1000
             101
                111
                 101
                    100
So the answer is 1110 remainder 100.
We can confirm this by converting to decimal numbers
1001010 = 74 and 101 = 5.
74 / 5 = 14 remainder 4.
