18:27 = 2/3
18/9 = 2 
27/9 = 3 
9 is the greatest common factor. 
 
        
                    
             
        
        
        
Answer:
 1, x/3, x^2/9, x^3/27,  x^4/81
x^4 +3x^3+9x^2+27x+81
----------------------------------------
81
Step-by-step explanation:
(x/3) ^i
i=0   (x/3)^0 = 1
i=1   (x/3)^1 = x/3
i=2   (x/3)^2 = x^2/3^2 = x^2/9
i=3   (x/3)^3 = x^3/3^3 =x^3/27
i=4   (x/3)^4 = x^4/3^4 =x^4/81
The sum is
1+(x/3) + x^2/9 + x^3/27 + x^4/81
We need a common denominator of 81
1*81/81 + x/3 *27/27 + x^2/9 *9/9 + x^3/27 *3/3 + x^4/81
81+27x + 9x^2 + 3x^3 +x^4
----------------------------------------
81
Rewriting from largest power to smallest power
x^4 +3x^3+9x^2+27x+81
----------------------------------------
81
 
        
             
        
        
        
0.00025 per min
300,000 min/month
so 300,000 x 0.00025= 75
you would drag and drop the 7.5 and the 10 with the 1

Answer:  576 </h3>
============================================================
Check out the diagram below.
I've split the figure into 3 separate blocks. We calculate the volume of each block, then add up those volumes to get the final answer.
- Block A = largest block on the left
- Block B = middle block
- Block C = smallest block on the right
So,
- volume of block A = length*width*height = 6*6*8 = 288 ft^3
- volume of block B = length*width*height = 6*6*5 = 180 ft^3
- volume of block C = length*width*height = 6*6*3 = 108 ft^3
Therefore, the total volume we're working with is: 
A+B+C = 288+180+108 = 576 cubic feet
The "cubic feet" or "ft^3" portion is already taken care of by your teacher, so you just need to type in the number itself.
