Answer:
lcm for cuberoot
2*2*2*5*5*5*3*3*3
for cuberoot we will make pairs of common three numbers and write them one time
2*5*3
30
check 30*30*30=27000
cube
multiply 27000 three times with itself
19683000000000.0 is the answer
 
        
                    
             
        
        
        
Answer:
The cost of each cotton candy bag is $4.
Step-by-step explanation:
Consider the provided information.
Let, the vendor has  dollar at the starting of each day.
 dollar at the starting of each day.
Let, the cost of each cotton candy bag is  .
.
Now when she sells a total of 12 bags, she has $128. 
 .....(1)
  .....(1)
After she sells a total of 20 bags, she has $160.
 ....(2)
  ....(2)
Subtract equation 1 from equation 2.



Hence, the cost of each cotton candy bag is $4.
 
        
             
        
        
        
What you would do is change all the fractions to 20ths so they have a common denominator. For 1/5, you multiply 4x5 to get 20 in the denominator. Whatever you multiply on the bottom, you must do at the top. Do that for all fractions and you would get this: 
4/20 + 5/20 + 8/20= 17/20 because denominator stays the same, add the values in the numerator.
ANSWER: 17/20

Answer:
Step-by-step explanation:
We have to make 5 place serial number with first two as alphabets and last three as digits.
The alphabets are bonded to first 6 ( A, B, C, D, E, F) where as digits are 10 (say 1 to 10).
Let the serial number be S1 S2 S3 S4 S5.
For Alphabets 
For S1 we have 6 alphabets. 
Now for S2 we are left with 5 alphabets since there is no repetition one alphabet will be fix for S1. 
So the possible combination for S1 S2= 6x5=30.
For Digits
We did the same as we did for alphabets, for S3 we have 10 possibilities, and for S4 and S5 9 and 8 respectively due to the no repetition condition. 
So the possible combinations for S3 S4 S5 = 10x9x8=720
So the total number of serial numbers are 30+720=750.
