Math Question: What is the sum of the ones and thousands digits when 4381 is multiplied by 4 and divided by the result of subtracting 9 from the cube of its tens digit?

To find the sum, we begin by computing the cube of the tens digit (8^3 = 512). Then subtracting 9 from 512 yields 503. When we multiply 4 by 4381, we get 17524. Finally, dividing 17524 by 503 gives us 34.798. Now, adding the ones digit (1) and the thousands digit (4) together, the sum is 5. Hence, the sum of the ones and thousands digits is 5.

Math Question: What is the sum of the smallest and largest two-digit numbers that are divisible by 7 and have the same units digit as the number 4381?

To find the answer, we need to determine the two-digit numbers that are divisible by 7 and have the same units digit as 4381. The smallest number meeting these criteria is 21 (as 21 mod 7 = 0), while the largest number is 91 (as 91 mod 7 = 0). Therefore, the sum of the smallest and largest two-digit numbers satisfying these conditions is 21 + 91 = 112.

Question: If the number 4381 is multiplied by 9 and then divided by the sum of its digits minus 2, what is the result?

To find the answer, first, we calculate the sum of the digits of 4381, which is 4 + 3 + 8 + 1 = 16. Subtracting 2 from the sum gives us 16 - 2 = 14. Now, multiplying 4381 by 9 gives 39429. Finally, we divide 39429 by 14 to find the result. Therefore, 4381 multiplied by 9 divided by the sum of its digits minus 2 equals 2816.35 (rounded to two decimal places).
