Math Question: If I divide a number by 6, add 20 to the result, multiply by 3, and subtract 10, I get 948. What is the number?

To find the number, let's work backwards: starting with 948, we add 10, then divide by 3, and finally subtract 20. Adding 10 to 948 gives us 958. Dividing this by 3 gives us approximately 319.33. Lastly, subtracting 20 from 319.33 gives us approximately 299.33. Therefore, the number we started with is approximately 299.33. Since the initial question doesn't specify whether the number needs to be an integer, 299.33 can be a valid solution.

Question: What is the sum of the digits in the number 948?

To find the sum of the digits in the number 948, we add the individual digits: 9 + 4 + 8 = 21. Therefore, the sum of the digits in the number 948 is 21.

Math question: What is the sum of all the prime numbers less than 948?

To find the sum of all prime numbers less than 948, we start by listing the primes up to that number - 2, 3, 5, 7, 11, 13, 17, 19, 23, ..., and so on, until we find the highest prime less than 948, which is 941. Now, we calculate the sum: 2 + 3 + 5 + 7 + 11 + 13 + 17 + 19 + 23 + ... + 941. Using the formula for the sum of an arithmetic series, Sn = (n/2)(a1 + an), where Sn is the sum, n is the number of terms, a1 is the first term, and an is the last term, we can find the sum by substituting the values. In this case, n = 471 (as there are 471 prime numbers less than 948), a1 = 2, and an = 941. Substituting in the formula, we get Sn = (471/2)(2 + 941) = 471/2 * 943 = 222,603. Therefore, the sum of all the prime numbers less than 948 is 222,603.
