What is the largest prime number less than 275 divisible by 3?

To find the largest prime number less than 275 divisible by 3, we start by checking the numbers in descending order. We divide each number by 3, and when we find a number that is prime (has no divisors other than 1 and itself), we know we have found our answer. After checking 274, 273, 272, and so on, we find that 271 is the largest prime number less than 275 divisible by 3.

Math question: What is the result when 275 is divided by the sum of its digits multiplied by the difference between its tens and units digit, subtracted by the square root of its units digit?

To find the solution, we break it down. The sum of the digits is 2 + 7 + 5 = 14. The difference between the tens and units digit is 7 - 5 = 2. The square root of the units digit (5) is approximately 2.24. Multiply the sum of digits (14) by the difference (2), which results in 28. Subtract the square root of the units digit (2.24) from this product to get 25.76. Finally, divide 275 by 25.76, yielding approximately 10.67. Therefore, when 275 is divided by the sum of its digits multiplied by the difference between its tens and units digit, subtracted by the square root of its units digit, the answer is approximately 10.67.

Math question: What is the sum of all odd integers from 1 to 275?

We can find the sum of consecutive odd integers using the formula Sn = n^2, where Sn is the sum of the first n odd integers. The number of odd integers from 1 to 275 is (275 - 1)/2 + 1 = 138. Therefore, the sum, Sn = 138^2 = 19044. Hence, the sum of all odd integers from 1 to 275 is 19044.
