Math question: What is the sum of 73 plus 45, divided by 9, multiplied by 2, and then subtracted by 5?

To solve the given expression, we start by calculating the sum: 73 + 45 = 118. Next, divide this sum by 9: 118 / 9 = 13.1111 (repeating). Now, multiply the result by 2: 13.1111 * 2 = 26.2222 (repeating). Finally, subtract 5: 26.2222 - 5 = 21.2222 (repeating). Hence, the answer to this math problem is approximately 21.2222.

Math Question: What is the sum of the first 73 positive odd numbers?

To find the sum of the first 73 odd numbers, we can use the formula for the sum of an arithmetic series with the first term a₁, the last term aₙ, and the number of terms n. The formula is Sn = (n/2)(a₁ + aₙ). Here, a₁ = 1, aₙ = 73, and n = 73. Plugging in these values, we get Sn = (73/2)(1 + 73) = 73 * 74/2 = 2701. Thus, the sum of the first 73 positive odd numbers is 2701.

Question: If 73 is multiplied by a certain number and then divided by the same number, the result is 73. What could be the number?

Let's assume the number to be x. So, we have (73 * x) / x = 73. By canceling out the x from the numerator and denominator, we're left with 73 = 73. Therefore, the number can be any non-zero quantity, such as real numbers other than zero, imaginary numbers, complex numbers, or even infinity.
