Math question: What is the sum of all even numbers between 1250 and twice the square root of 1250?

To find the sum of even numbers between 1250 and twice the square root of 1250, we need to calculate: 1. Find the square root of 1250: √1250 ≈ 35.36. 2. Multiply the square root by 2: 35.36 × 2 ≈ 70.72. 3. Identify the even numbers between 1250 and 70.72 (exclusive): 1252, 1254, 1256, ..., 69. 4. Use the formula for the sum of an arithmetic sequence: S = (n/2)(a + l), where S represents the sum, n is the number of terms, a is the first term, and l is the last term. 5. Determine the number of terms between 1252 and 68 (inclusive): (68 – 1252)/2 + 1 = 469. 6. Calculate the sum: S = (469/2)(1252 + 68) = 268,022. Therefore, the sum of even numbers between 1250 and twice the square root of 1250 is 268,022.

Math question: If John has 1250 dollars and spends 40% of it on groceries, how much money will he have left?

To calculate the amount John will have left, we find 40% of 1250 by multiplying 1250 by 0.40, which equals 500. Subtracting 500 from 1250, John will have 750 dollars left. Therefore, John will have $750 remaining after spending 40% of his initial $1250 on groceries.

What is the sum of 1250, its square, and its cube divided by 5?
