Math question: Using the digits 4, 8, 9, and 0, create the largest possible four-digit number. Find the sum of its digits, double it, subtract 5, multiply by 10, divide by 2, square it, and then add 3. What is the final result?

To create the largest four-digit number using 4, 8, 9, and 0, you arrange them in descending order: 9840. The sum of the digits is 9 + 8 + 4 + 0 = 21. Doubling that gives 42, subtracting 5 gives 37, multiplying by 10 equals 370, dividing by 2 is 185, squaring it results in 34225, and finally adding 3 gives us the final result of 34228.

Question: What is the largest 4-digit number that is divisible by 90, ends with zero, and has no repeating digits?

The largest 4-digit number that is divisible by 90, ends with zero, and has no repeating digits is 9680. To find this number, we know that a number is divisible by 90 if it is divisible by both 9 and 10. For a number to end with zero, it must be divisible by 10. To ensure that there are no repeating digits, we need to find the largest possible combination of distinct digits. Starting from the largest digit, 9 is used as the highest possible unit digit as 9 is not divisible by 9. The remaining unassigned digits are 8, 6, and 0. We arrange the digits in decreasing order from left to right to form 9680.

Math question: What is the smallest multiple of 17 that is greater than 4890?

To find the smallest multiple of 17 greater than 4890, we divide 4890 by 17 and find the remainder. Dividing 4890 by 17 gives us 287 with a remainder of 1. Since the remainder is 1, we add 17 to 4890 to get the next multiple of 17, which is 4907. Therefore, the smallest multiple of 17 greater than 4890 is 4907. In summary, the smallest multiple of 17 greater than 4890 is 4907.
