Math question: Divide 2720 by 34, subtract 18, and then add 6 times the square root of 25. What is the final result?

To solve this problem, we begin by dividing 2720 by 34, which gives us 80. Afterwards, we subtract 18 from this result, resulting in 62. Finally, we add 6 times the square root of 25, which is 6 times 5 equaling 30. Therefore, the final answer is 62 + 30 = 92.

Math question: What is the sum of all integers from 1 to 2720?

To find the sum of all integers from 1 to 2720, we can use the formula for the sum of an arithmetic series: S = (n/2)(first term + last term), where S represents the sum, n represents the number of terms, and the first term is 1. The last term can be found by substituting 2720 for n in the formula: 2720/2(1 + 2720) = 1360(1361) = 1,848,560. Therefore, the sum of all integers from 1 to 2720 is 1,848,560.

Math question: The number 2720 is divisible by which of the following prime numbers: 2, 3, 5, 7, or 11? Explain your answer.

To determine if 2720 is divisible by a prime number, we need to check if it is divisible by each of the prime numbers listed. For 2: Since 2720 is even, it is divisible by 2. For 3: The sum of its digit (2+7+2+0=11) is not divisible by 3, so 2720 is not divisible by 3. For 5: As 2720 ends in a 0 or 5, it is divisible by 5. For 7: To check divisibility by 7, we can double the last digit (0), then subtract it from the truncated remaining number, resulting in 272. As 272 (2*7*2) is a multiple of 7, so is 2720. For 11: By calculating alternating sums of digits (2-7+2-0= -3), the difference is not divisible by 11, thus 2720 is not divisible by 11. In conclusion, the prime numbers that 2720 is divisible by are 2, 5, and 7.
