Math question: What is the sum of all the odd numbers from 1 to 1775 (inclusive)?

To find the sum of odd numbers, consider that each odd number is given by 2n + 1, where n is a non-negative integer. The highest odd number, given by 2n + 1, should be less than or equal to 1775, meaning n ≤ (1775 - 1) / 2 = 887. So, the sum of odd numbers from 1 to 1775 is given by the sum of an arithmetic series: (n / 2) * (first odd number + last odd number) = (887 / 2) * (1 + 1775) = 394,187. Therefore, the sum of all odd numbers from 1 to 1775 is 394,187.

Math question: What is the sum of the prime factors of 1775?

To find the prime factors of 1775, we prime factorize it as 5 × 5 × 71. The sum of these prime factors is 5 + 5 + 71 = 81.

Question: If 15% of a number is 266.25, what is the number?

To find the number, we need to solve for x in the equation 0.15x = 266.25. Dividing both sides by 0.15, we get x = 1775. Therefore, the number we are looking for is 1775.
