Math question: What is the remainder when 211 is divided by 7?

To find the remainder, we divide 211 by 7 using long division. The quotient is 30 with a remainder of 1. Therefore, the remainder when 211 is divided by 7 is 1.

Math Question: If a number is increased by 42 and then divided by 3, the result is equal to 91. What is the original number?

Let's assume the original number is x. According to the given question, (x + 42) ÷ 3 = 91. To find the value of x, we can simplify the equation. Multiplying both sides by 3, we get x + 42 = 273. Subtracting 42 from both sides, we find x = 231. Therefore, the original number is 231.

Math question: What is the sum of triple the number 211, subtracted by half of its square root, divided by the number itself, and squared?

To find the sum, we begin by tripling 211, which equals 633. Then, we calculate half of the square root of 211, which is approximately 10.28. Subtracting this value from 633 gives us 622.72. Next, we divide 622.72 by 211, resulting in approximately 2.9516. Finally, we square this value to get approximately 8.7185. Therefore, the answer is approximately 8.7185.
