Math question: What is the sum of all the odd numbers between 1 and 219?

To find the sum of all odd numbers between 1 and 219, we need to add up these numbers. The sum of an arithmetic series can be found using the formula Sn = (n/2)(a + l), where Sn represents the sum of the series, n is the number of terms, a is the first term, and l is the last term. By identifying that 1 is the first odd number and 219 is the last odd number in the given range, we can calculate the sum. In this case, a = 1 and l = 219. To determine the number of terms, we can use the formula an = a + (n - 1)d, where an represents the nth term, a is the first term, n is the number of terms, and d is the common difference. Since the sequence of odd numbers has a common difference of 2, we can substitute these values into the formula. 219 = 1 + (n - 1)2 218 = 2n - 2 220 = 2n n = 110 Now, substituting the known values into the sum formula: Sn = (n/2)(a + l) Sn = (110/2)(1 + 219) Sn = 55 * 220 Sn = 12,100 Therefore, the sum of all odd numbers between 1 and 219 is 12,100.

Math question: What is the sum of the square root of 219, twice the cube of its tens digit, and half its units digit, divided by the difference between its tens and units digit?

To solve this, let's break it down step by step. Firstly, the square root of 219 is approximately 14.7987. Secondly, the tens digit is 1, so twice the cube of 1 equals 2. Lastly, the units digit is 9, and half of it is 4.5. Now, let's calculate. Adding these three values gives us 14.7987 + 2 + 4.5 = 21.2987. The difference between the tens and units digit is 1 - 9 = -8. Therefore, dividing our sum by -8 gives us -21.2987 / -8 = 2.6623375. Therefore, the answer is 2.6623375.

Math question: What is the sum of the digits and the average of the digits when the number 219 is squared?

To find the square of 219, we calculate 219^2 = 48061. The sum of the digits in 48061 is 4 + 8 + 0 + 6 + 1 = 19. The average of the digits is found by dividing the sum by the number of digits, which is 19 ÷ 5 = 3.8.
