6*5*4*3*2*1 = 720
There are 6 numbers between 1 and 70 that are divisible by 11. These numbers are: 11; 22; 33; 44; 55; 66.
Just one possibility.... 1001
119
There are 90 such numbers.

There are many possible answers. 10,11,11,17,18 is one such set.
The only possible pair of different positive numbers is (1, 11).
The number of different three letter arrangements that can be done from theletters in the word "mathematics"is; 11P3 =11!/(11-3)! =990
There are infinitely many possible answers. One such is {9, 10, 11, 13, 14, 15}.There are infinitely many possible answers. One such is {9, 10, 11, 13, 14, 15}.There are infinitely many possible answers. One such is {9, 10, 11, 13, 14, 15}.There are infinitely many possible answers. One such is {9, 10, 11, 13, 14, 15}.

How many numbers from 11 to 50 are there which are exactly divisible by 7 but not by 3? Five Four Six Two * * * * * Good strategy! List all possible values and one of them must be correct! The correct answer is 4.

There are 36 possible characters (26 letters + 10 numbers) that can be used in each position of the 11-digit combination. Therefore, the total number of possible combinations is 36^11, which is approximately 7.52 x 10^17. This means there are over 750 quadrillion possible 11-digit combinations of letters A-Z and numbers 0-9 when combined.
11!/(3!3!2!2!) = 39916800/144 = 277200
The composite numbers between 11 and 29 are 12,14,15,16,18,20,21,22,24,25,26,27 & 28.
