How many different four digit combinations are there of the numbers zero through nine and using one number twice in the combination?
There are 360 of them.
How many different three digit numbers can be written using the digits 1 through 9?
You can select 9 numbers for the first digit, 8 numbers for the second digit, and 7numbers for the third digit; so 504 (e.g. 9*8*7) different three digit numbers can be written using the digits 1 through 9.
What are every possible 10 digit combinations of the numbers 0 through 9?
There is only one combination since the order of the numbers in a combination does not matter.
What are some 5-digit numbers that are divisible by 4 and 9?

How many 10 digit phone numbers are possible?
Without restrictions, it was would numbers 000-000-0000 through 999-999-9999. So that would be 9,999,999,999 + 1 = 10 billion different 10-digit phone numbers. Ex: If there existed single digit phone numbers, there would be 10, because the digits are 0 through 9. If there existed only double digit phone numbers, then it would be 00 through 99 which would be 100 total two-digit numbers. Therefore the total possible combinations for an X digit phone number would be: 10^X
