To find the number of 3-digit combinations using the digits 0 to 9 with repetition allowed, we consider that each digit can be any of the 10 digits (0-9). Since there are 3 positions in the combination, the total number of combinations is calculated as (10 \times 10 \times 10), which equals 1,000. Therefore, there are 1,000 possible 3-digit combinations.

What are all the ways to combine 123456789 in 7 digits without repeating?
To combine the digits 1 through 9 into 7-digit combinations without repeating any digits, you can select any 7 digits from the 9 available. The number of ways to choose 7 digits from 9 is given by the combination formula ( C(9, 7) ), which equals 36. Each selection of 7 digits can then be arranged in ( 7! ) (factorial) ways. Therefore, the total number of 7-digit combinations is ( 36 \times 7! = 36 \times 5040 = 181440 ).
