Math Question: How many different 4-digit numbers can be formed using the digits from the number 7130 without repetition?

To find the number of different 4-digit numbers without repetition, we first determine the number of choices for each digit. There are 4 choices for the thousands place since the digit cannot be zero. For the hundreds place, we have 3 remaining digits to choose from. Similarly, for the tens place, we have 2 choices, and for the units place, we have only 1 choice left. By multiplying these choices together, we get: 4 * 3 * 2 * 1 = 24. Therefore, there are 24 different 4-digit numbers that can be formed using the digits from the number 7130 without repetition.

Question: What three-digit number can be evenly divided by 10, 7, and 13, and is greater than 7000 but less than 7200?

The three-digit number that satisfies all the given conditions is 7160. To confirm this, let's check each condition separately. Firstly, we can see it is divisible by 10 since it ends in 0. Secondly, it is divisible by 7, as the sum of the first digit (7) minus twice the last digit (2*0) is 7 - 0 = 7, which is a multiple of 7. Finally, it is divisible by 13, since the sum of 13 and twice the last digit (2*0) is 13 + 0 = 13, which is also a multiple of 13. Therefore, 7160 meets all the criteria, making it the correct answer.

Math question: How many prime factors does the number 7130 have?

To find the prime factors of 7130, we need to factorize it. Prime factor of 7130 = 2 × 5 × 19 × 19. Therefore, 7130 has 4 prime factors: 2, 5, 19, and 19.
