Question: What is the sum of the digits when 1139 is multiplied by its reverse?

To calculate the product, we multiply 1139 by 9311 (reverse of 1139) resulting in 10,564,729. Now, finding the sum of the digits, we add 1 + 0 + 5 + 6 + 4 + 7 + 2 + 9 which yields 34. Hence, the sum of the digits when 1139 is multiplied by its reverse is 34.

Question: If the number 1139 is multiplied by 3 and then divided by 2, what is the result?

To find the result, we multiply 1139 by 3 which gives us 3417. Then, we divide 3417 by 2, resulting in 1708.5. Therefore, the result of multiplying 1139 by 3 and then dividing by 2 is 1708.5.

Math Question: What is the result of dividing 1139 by 13, subtracting 7, multiplying by twice the square root of 17, and adding the cube root of 27 multiplied by 5 to the power of 4? Math

Let's break it down step by step. First, divide 1139 by 13, which equals 87.6153846. Then, subtract 7 from this result to get 80.6153846. Next, multiply by twice the square root of 17 (2√17), resulting in 272.0355786. Now, compute the cube root of 27, which is 3. Finally, raise 5 to the power of 4, yielding 625. Multiply the cube root of 27 by 625, giving 1875. Add this to the previous result (272.0355786), resulting in 2147.035579. Therefore, the answer is 2147.035579.
