What is the sum of the prime factors of the number 2955?

The prime factors of 2955 are 3, 5, 197, so the sum is 3 + 5 + 197 = 205.

Math question: What is the sum of the digits of three times the square root of the product of 2955 and the cube root of 2955?

To solve this problem, first find the square root of 2955 and the cube root of 2955. Multiply these two values together, and then multiply the result by 3. Now, sum up the digits of this final value. Let's calculate step by step: Square root of 2955 ≈ 54.3015 Cube root of 2955 ≈ 14.0086 Multiplying these values: 54.3015 * 14.0086 ≈ 760.4209 Now, multiply by 3: 760.4209 * 3 ≈ 2281.2628 Summing up the digits: 2 + 2 + 8 + 1 + 2 + 6 + 2 + 8 = 31 Hence, the sum of the digits of three times the square root of the product of 2955 and the cube root of 2955 is 31.

Math Question: How many two-digit numbers are divisible by 5 between 1000 and 3000?

To find the answer, we first calculate the smallest two-digit multiple of 5 greater than or equal to 1000. Dividing 1000 by 5, we get 200. So, the smallest two-digit multiple of 5 is 2000. Next, we calculate the largest two-digit multiple of 5 less than or equal to 3000. Dividing 3000 by 5, we get 600. So, the largest two-digit multiple of 5 is 3000. Now, to find the count of two-digit numbers divisible by 5 in this range, we subtract the two values: 3000 - 2000 = 1000. Therefore, there are 1000 two-digit numbers divisible by 5 between 1000 and 3000.
