Math question: What is the square root of 766, when rounded to the nearest tenth?

To find the square root of 766, we can use the Newton-Raphson method. With initial estimation as 25, the algorithm converges to the square root of 766 as approximately 27.7. Rounding it to the nearest tenth, we get 27.7. Therefore, the square root of 766, rounded to the nearest tenth, is 27.7.

Math question: What is the sum of the digits in the number 766?

The sum of the digits 7, 6, and 6 is 19.

What is the sum of all even numbers between 100 and 766, inclusive?

To find the sum of the even numbers, we first need to determine the number of terms in the given range. The first even number in the range is 100 and the last even number is 766. The formula to find the number of terms in an arithmetic series is: number of terms = (last term - first term)/common difference + 1. In this case, the common difference is 2. Substituting the values into the formula, we get: number of terms = (766 - 100)/2 + 1 = 333. Now we can find the sum of the even numbers using the arithmetic series sum formula: sum = (number of terms/2) * (first term + last term). Plugging in the values, we get: sum = (333/2) * (100 + 766) = (166.5) * (866) = 144057. Therefore, the sum of all even numbers between 100 and 766, inclusive, is 144057.
