Math Question: If x represents the square root of 2, what is the value of 270 + 3x^2 - 15?

To find the value, substitute x = √2 into the equation. Thus, 3(√2)^2 equals 3 * 2 equals 6. Now, substitute all the values: 270 + 6 - 15 equals 261. Therefore, the value of the expression is 261.

Math Question: If a quantity is increased by 120 and then decreased by 50% of the result, what is the final value of the quantity if the initial value is 270?

To solve this, we start by increasing 270 by 120 which gives us 390. Then, we find 50% of 390, which is 195. Subtracting 195 from 390 yields 195. So, the final value of the quantity is 195.

Math question: In a classroom, there are 30 students who each contribute the same amount to a charitable cause. If they raise a total of $270, how much money did each student contribute?

To find the amount each student contributed, we divide the total amount raised, which is $270, by the number of students, which is 30. Therefore, each student contributed $9 ($270 ÷ 30 = $9). This means that each student donated $9 towards the charitable cause.
