120, if you use each number once.
there are 63 combos
That depends entirely on the number of digits each number is permitted to have !
9,999 different combos well 10,00 if you add 0 in with it
By making a number tree that could have as many as 1,000,000 combos.
The answer will depend on how many digits there are in each of the 30 numbers. If the 30 numbers are all 6-digit numbers then the answer is NONE! If the 30 numbers are the first 30 counting numbers then there are 126 combinations of five 1-digit numbers, 1764 combinations of three 1-digit numbers and one 2-digit number, and 1710 combinations of one 1-digit number and two 2-digit numbers. That makes a total of 3600 5-digit combinations.
There are five.
There are five odd numbers on an odd number cube?
252 combinations, :)
Only one.

None. No number between 1 and 100 has 5 of any digit.This is incorrect. The question asks how many has five ones, not digits.the number five has five ones in the ones column the number 50 has five tens in the tens column. so the answer is 10: 5,15,25,35,45,55,65,75,85,95. Al these numbers have five ones in the ones column.
