Math question: What is the sum of the first 20 positive odd numbers greater than 667?

To find the sum of the first 20 odd numbers greater than 667, we can observe that these numbers form an arithmetic sequence with a common difference of 2. The first term is 669, and the last term is 707. Using the formula for the sum of an arithmetic series, S = (n/2)(a + l), where S is the sum, n is the number of terms, a is the first term, and l is the last term, we substitute the given values into the formula. Here, n = 20, a = 669, and l = 707. Thus, S = (20/2)(669 + 707) = 10(1376) = 13760. Therefore, the sum of the first 20 positive odd numbers greater than 667 is 13760.

Math question: What is the square root of 667 rounded to the nearest tenth?

The square root of 667 is approximately 25.81 when rounded to the nearest tenth. The square root is found by finding the number that, when multiplied by itself (25.81 x 25.81), gives the result closest to 667.

Math question: How many times can the number 3 be evenly divided into the number 667?

To find the number of times 3 can be evenly divided into 667, we divide 667 by 3. The quotient is 222 with a remainder of 1. This means that 3 can be divided into 667 exactly 222 times without any leftovers.
