Math Question: If 50% of a number is equal to 1045, what is the number?

To find the number, we can set up an equation. Let x represent the number, so we have (50/100)x = 1045. Simplifying, we get x/2 = 1045. Multiplying both sides by 2, we obtain x = 2 * 1045. Therefore, the number is 2090.

Math question: What is the sum of all the odd numbers between 1000 and 2090 (inclusive)?

To find the sum, first calculate the number of odd numbers between 1000 and 2090 using the formula (last number - first number) / 2 + 1. In this case, it is (2090 - 1000) / 2 + 1 = 546 odd numbers. The average of an arithmetic sequence can be found by the formula (first number + last number) / 2. So, the average of these odd numbers is (1001 + 2090) / 2 = 1545.5. The sum of the sequence can be calculated using the formula sum = average * number of terms, which gives 1545.5 * 546 = 843897. Therefore, the sum of all odd numbers between 1000 and 2090 is 843897.

Question: If 2090 is divided by the sum of all its digits multiplied by the product of its digits, what is the result?

To find the sum of the digits of 2090, we have 2 + 0 + 9 + 0 = 11. The product of the digits is 2 * 0 * 9 * 0 = 0. Hence, we need to divide 2090 by 11 * 0 = 0. Dividing any number by zero is undefined, so the result is undefined or does not exist.
