Math Question: If a number is multiplied by 5, decreased by 175, then divided by 2, the result is 3805. What is the original number?

Let's denote the unknown number as x. According to the given conditions, the equation becomes (5x - 175) / 2 = 3805. To find x, we'll solve for it step-by-step. First, multiply 3805 by 2, resulting in 7610. Next, add 175 to both sides of the equation: 5x - 175 = 7610 + 175, simplifying to 5x - 175 = 7785. Now, adding 175 to both sides: 5x = 7785 + 175, yielding 5x = 7960. Finally, dividing both sides by 5: x = 7960 / 5, which gives x = 1592. Therefore, the original number is 1592.

Math question: What is the sum of the squares of the hundreds, tens, and units digits of the number 3805?

To find the sum of the squares, we first identify the hundreds, tens, and units digits. The hundreds digit is 3, the tens digit is 8, and the units digit is 5. Now, we square each digit individually: 3^2 = 9, 8^2 = 64, and 5^2 = 25. Finally, we sum up these squares: 9 + 64 + 25 = 98. Thus, the sum of the squares of the hundreds, tens, and units digits of the number 3805 is 98.

What is the product of the digits in the number 3805?

The product of the digits 3, 8, 0, and 5 is 0.
