Math question: What is the sum of the digits of the number 9994?

To find the sum of the digits of a number, we add each digit together. For 9994, the sum would be 9 + 9 + 9 + 4 = 31. Now let's explain in detail how we arrived at the answer: To begin, we break down the given number 9994 into its individual digits. These digits are 9, 9, 9, and 4. We then add each digit together: 9 + 9 + 9 + 4 = 31. Hence, the sum of the digits of the number 9994 is 31.

Math Question: What is the sum of all positive odd integers less than 9994 that are divisible by both 3 and 5?

To solve this problem, we need to find the highest odd multiple of 15 less than 9994. Divide 9994 by 15 to get 666 remainder 4. The highest odd multiple of 15 less than or equal to 9994 is 9975, which is 15*665. Now, find the number of odd multiples of 15. Since every other multiple of 15 is odd, we divide 665 by 2 to get 332 remainder 1. Now, we have the number of odd multiples of 15. So, the sum of all positive odd integers less than 9994 divisible by both 3 and 5 is calculated using the formula for the sum of an arithmetic progression: Sum = (first term + last term) * number of terms / 2 First term: 15 (smallest odd multiple of 15) Last term: 9975 (highest odd multiple of 15 less than 9994) Number of terms: (332 / 2) + 1 = 167 Thus, the sum = (15 + 9975) * 167 / 2 = 50130. Hence, the sum of all positive odd integers less than 9994 that are divisible by both 3 and 5 is 50130.

Math question: How many prime factors does the number 9994 have?

To determine the prime factors of 9994, we need to factorize it. Dividing 9994 by the smallest prime number, 2, we get 4997. In this case, 4997 is a prime number. Hence, the prime factorization of 9994 is 2×4997. Therefore, the number 9994 has two prime factors: 2 and 4997.
