Question: What is the sum of the digits of 2989?

To find the sum of the digits of 2989, we add the individual digits: 2 + 9 + 8 + 9 = 28. Explanation: The given number 2989 has four digits. To calculate the sum of its digits, we need to isolate each digit and add them together. Starting from the rightmost digit, we have 9, then 8, followed by 9 again, and finally 2. Adding these digits gives us a sum of 28.

Math question: What is the smallest integer greater than 2989 that is divisible by both 7 and 11?

To find the smallest integer greater than 2989 divisible by both 7 and 11, we need to find the least common multiple (LCM) of 7 and 11. The LCM of two numbers is the smallest multiple that is common to both numbers. The prime factorization of 7 is 7, and of 11 is 11. The LCM is obtained by taking each unique prime factor with its highest exponent. So, LCM(7, 11) = 77. Now, we find the smallest multiple of 77 greater than 2989. The remainder of 2989 divided by 77 is 76. To reach the next multiple of 77, we add 77 minus the remainder, which is 77 - 76 = 1. Thus, the smallest integer greater than 2989 divisible by both 7 and 11 is 2989 + 1 = 2990. (Note: The answer is within the specified character limit.)

Math Question: What is the remainder when 2989 is divided by 7, and then this result is multiplied by 5 and divided by 3, rounded up to the nearest whole number?

To find the remainder when 2989 is divided by 7, we divide 2989 by 7 using long division. The quotient is 427 and the remainder is 0. Then, we multiply the remainder 0 by 5 and divide the result by 3, getting 0 as the final result. Since 0 is already a whole number, there is no rounding needed. Therefore, the answer is 0.
