How many 6 digit different locker combinations are possible if no repeat numbers are allowed?
Alex_Xolod [135]

Since we are trying to find the number of sequences can be made <em>without repetition</em>, we are going to use a combination.


The formula for combinations is:

_n C _k = \dfrac{n!}{k! (n - k)!}

  • n is the total number of elements in the set
  • k is the number of those elements you are desiring

Since there are 10 total digits, n = 10 in this scenario. Since we are choosing 6 digits of the 10 for our sequence, k = 6 in this scenario. Thus, we are trying to find _{10} C _6. This can be found as shown:

_{10} C _6 = \dfrac{10!}{6! \cdot 4!} = \dfrac{10 \cdot 9 \cdot 8 \cdot 7}{4!} = \dfrac{5040}{24} = 210


There are 210 total combinations.

Two similar pyramids have lateral areas 20ft2 and 45ft2. The volume of the smaller pyramid is 8ft3.
Artemon [7]
Let the ratio between 2 of them be a/b. The volume of the larger one is x (ft^3) 
<span>(a/b)^2 = 20/45 = 4/9 ---> a/b = 2/3 </span>
<span>(a/b)^3 = 8/x </span>
<span>8/x = (2/3)^3 = 8/27 ---> x = 27 (ft^3) </span>
