Most likely you saw a number written beginning with 011-371-2. 011 is not part of the country code, it is the international access prefix for calls originating in North America (USA, Canada, etc.). Country code +371 is Latvia, and +371 2 is a mobile number.
The half of 11-371 is calculated by first finding the result of the subtraction, which is 11 - 371 = -360. Then, half of -360 is -180. Thus, the half of 11-371 is -180.
To determine what number makes 371 divisible by 3, we need to sum the digits of 371: 3 + 7 + 1 = 11. To be divisible by 3, the sum of the digits must also be divisible by 3. Since 11 is not divisible by 3, we need to find the number that, when added to 11, results in a sum divisible by 3. The next multiple of 3 greater than 11 is 12, so the number that makes 371 divisible by 3 is 1.
By number theory, half of 371's factors will be less than its square root. Since 371 is less than 400, the square root will be less than 20. Since 371 is odd, all of its factors will be odd. By the rules of divisibility, we know that 371 is not divisible by 3, 5 or 9, so all we have to check is 7, 11, 13, 15, 17 and 19. 371 ÷ 7 = 53, so 371 is not prime.

It is 15 days and 11 hours.
The date would be 15 days after the date of the day you are measuring from, and the time on that day would be 11 hours later, so it would be 8pm.
Each day contains 24 hours. Therefore, the answer is 371/24 = about 15.46 or exactly 15-11/24 days.
371 hrs is 15 days and 11 hours. There are 31 days in january, so jan 18 + 15 days is 2nd of feb. 9am+11 hours is 8pm. It will be 8pm on 2nd of February.
next prime number would be 11
121 = 11 x 11
It depends on what country you are talking about.
The atomic number is determined by the number of Protons. So in this case it would be 11 (Sodium). The mass number is the total of protons and neutrons, so in this case 23. So this isotope of sodium would be 23Na.
