Math Question: What is the sum of all odd numbers less than 56 and divisible by 3, subtracted from the product of the square root of 56 and 2 multiplied by the harmonic mean of 56 and the cube of 56?

To find the sum, we first consider the odd numbers less than 56 and divisible by 3. These numbers are 3, 9, 15, 21, 27, 33, 39, 45, 51. Summing them, we get 243. Now, let's calculate the square root of 56, which is approximately 7.483. We'll multiply it by 2, giving us 14.966. Next, we need to compute the harmonic mean of 56 and the cube of 56. The cube of 56 is 179,776. To find the harmonic mean, we take the reciprocal of the average of the reciprocals: (2/((1/56) + (1/179776))). Simplifying, we find the harmonic mean is approximately 37.5143. Finally, we multiply 14.966 by 37.5143, resulting in 561.1347. To obtain the answer, we subtract the sum of odd numbers (243) from the product of the square root of 56, 2, and the harmonic mean (561.1347 - 243), which equals approximately 318.1347.

Math question: What is the product of 56 multiplied by its sum with its double?

To find the product, we first calculate the sum: 56 + (56 x 2) = 56 + 112 = 168. Now we multiply 56 by 168: 56 x 168 = 9408. Therefore, the product of 56 multiplied by its sum with its double is 9408.

Math question: If 56 is divided by the sum of its digits and multiplied by the difference between its tens and units digits, what is the result?

To solve this problem, we start by finding the sum of the digits in 56: 5 + 6 = 11. Next, we determine the difference between the tens and units digits: 6 - 5 = 1. Then, we divide 56 by the sum of its digits: 56 ÷ 11 = 5.0909... (approx.). Finally, we multiply the result by the difference between the tens and units digits: 5.0909... × 1 = 5.0909...(approx.). Therefore, the result of dividing 56 by the sum of its digits and multiplying by the difference between its tens and units digits is approximately 5.0909.
