Math question: Find the sum of all even numbers less than 2023 but not divisible by 5.

To solve this problem, let's start by listing down the even numbers less than 2023. We have 2, 4, 6, 8, ..., 2022. Now, let's identify the numbers that are divisible by 5 among the even numbers. From this list, 10, 20, 30, ..., 2020 are divisible by 5. Next, let's calculate how many terms are present in the list of even numbers. We can use the formula for the nth term of an arithmetic series: an = a + (n - 1)d. Here, a = 2, d = 2 (the common difference), and an 2022 = 2 + (n - 1)2 2020 = 2n - 2 n = 1011 Out of the 1011 terms, we identified that 404 are divisible by 5. Therefore, there are 607 even numbers less than 2023 that are not divisible by 5. Now, let's find the sum using the formula for an arithmetic series: Sn = (n/2)(a + l), where Sn is the sum, n is the number of terms, a is the first term, and l is the last term. Sum = (607/2)(2 + 2022) Sum = 303.5(2024) Sum = 614,712 So, the sum of all even numbers less than 2023 but not divisible by 5 is 614,712.

Math question: What is the sum of the digits when the number 2023 is multiplied by 3 and then divided by 7?

To find the sum of the digits when 2023 is multiplied by 3 and divided by 7, we first multiply it by 3: 2023 * 3 = 6069. Then, we divide 6069 by 7, getting the quotient 867 and remainder 0. Now, we need to find the sum of the digits in 867. The sum is calculated as: 8 + 6 + 7 = 21. Hence, the answer is 21.

Math question: What is the result when 2023 is multiplied by the sum of its digits, and then divided by the product of its digits, rounded to the nearest whole number?

To solve this, we first find the sum and product of the digits of 2023. The sum is 2 + 0 + 2 + 3 = 7, and the product is 2 × 0 × 2 × 3 = 0. Now, we multiply 2023 by 7, which gives 14,161. Finally, we divide 14,161 by 0 and round to the nearest whole number. However, division by zero is undefined, so the answer is undefined.
