What are the odd numbers between 10 and 30 as the sum of three odd primes?
10
What are the composite numbers from 10-30?
11, 13, 17, 19, 23, 29 are the primes between 10 and 30 so the composite numbers are all the others. 12,14,15,16,18,20,21,22,24,25,26,27,28, and 30 are the composite numbers between 10 and 30.
Why the even numbers between 20 and 30 cant be primes?
Every even number is evenly divisible by 2.
What fraction of numbers 1 to 30 is prime?
Simply add up the primes - those numbers other than 1 whose only factors are 1 and themselves. 2,3,5,7,11,13,17,19,23,29 are all the primes from 1 to 30. There are 10 of them, and the set of integers from 1 to 30 encompasses 30 numbers, so 1/3 of the integers from 1 to 30 are prime. Technically there are infinite NUMBERS between 1 and 30 (0.1, 9.57, 0.000001, ...) but only 30 integers (1,2,3, ...). If the question is phrased with the word "numbers" and not "integers" then the answer should technically be 10 primes divided by infinite numbers, and anything over infinity is 0, so your answer would be 0. So answer either 1/3 or 0; if you haven't really talked about infinity then it is probably 1/3 they are looking for.
What are the prime numbers between 30 and 40?
The prime numbers between 30 and 40 are 31 and 37.The prime numbers between 30 and 40 are 31 and 37.
Which are the twin primes between 30 and 60?
The only twin primes (prime numbers which differ by 2) between 30 and 60 are (41, 43)
What are the odd numbers between 10 and 30 as the sum of three odd primes?
10
What are the composite numbers from 10-30?
11, 13, 17, 19, 23, 29 are the primes between 10 and 30 so the composite numbers are all the others. 12,14,15,16,18,20,21,22,24,25,26,27,28, and 30 are the composite numbers between 10 and 30.
How many prime numbers are there between 30 and 40?
31 and 37 are the only two so there are two primes between 30 and 40.
Why the even numbers between 20 and 30 cant be primes?
Every even number is evenly divisible by 2.
What are the whole numbers that are factors of 30?
Factors are prime numbers. The primes hidden in the number 30 are: 2,3, and 5.
Primes numbers 30 99 47 or 100?
Just 47.
How do you write 30 as a product of its prime factor?
29 is already prime. Prime numbers can't be products of primes.
What are the primes between 21 and 30?
23 and 29
What are the primes between 30 and 40?
They are: 31 and 37

Can a product of primes be split into sum of three products of primes?
Sure. All composite numbers can be written as a product of primes. It shouldn't be tough to find a composite number that's the sum of three other composite numbers. Let's try 30. 2 x 3 x 5 = 30 Product of primes, check. 6 (2 x 3) + 10 (2 x 5) + 14 (2 x 7) = 30 Sum of three products of primes, check.
