Math question: What is the smallest prime number greater than 386 that is divisible by 7?

To find the smallest prime number greater than 386 but divisible by 7, we can start by checking numbers greater than 386. Testing 387, 388, 389, we find that the number 390 is the smallest number divisible by 7 that is greater than 386. However, 390 is not prime since it is divisible by 2, 3, 5, and 7. Therefore, we continue searching by adding multiples of 7 to 390, which gives us 397, 404, 411, and so on. Ultimately, we discover that the smallest prime number greater than 386 and divisible by 7 is 397.

Math question: What is the sum of twice the square root of 386, divided by the cube root of 386, plus the square root of 386, when rounded to the nearest hundredth?

To calculate the sum, we need to evaluate the expression (2√386 / ∛386) + √386. First, simplify the cube root of 386 (∛386 ≈ 7.66). Now, substitute the values: (2√386 / 7.66) + √386. Simplify the square root of 386 (√386 ≈ 19.65). Multiply and divide accordingly: (2 * 19.65 / 7.66) + 19.65. Calculate the numerator: 39.3. Divide 39.3 by 7.66 to obtain approximately 5.12. Adding 5.12 to 19.65 equals about 24.77. Hence, the sum is approximately 24.77 when rounded to the nearest hundredth.

Question: If 386 is divided by 2 and then multiplied by 5, what is the result?

To find the result, we divide 386 by 2 to get 193. Then, we multiply 193 by 5, which gives us 965. Therefore, when 386 is divided by 2 and then multiplied by 5, the result is 965.
