### What are all the prime numbers 1000-1500?

the answer could have something to the ratio of prime numbers between 0 and 9 to the the number of prime primes between 9 and 625 and the number of primes between the square 25x25. Hint: the are 9 primes between 0 and 25. There are 114 primes between 25 and 625. There is a square number somewhere near 1000. 961 which is the Mercienne prime number 31 squared. without giving the answer away, by dividing 625 by 9 we get the ratio 12.6666667 or 12 and 2 3rds. this is one of many ratio to help find how many prime numbers within a given range. once the precise ascending pattern of prime numbers is discovered then any prime number to infinity can be calculated and identified disclosure: this information is designed to provide food for thought on the matter of the question above and is not a precise answer.

### What is the difference between synthetics and composites?

Composites means which is made of composition of two constituents where as synthetics is the combination of two or more parts, composites having constituents of different physical and chemical properties, where as in case of synthetics it can have same chemical or physical properties,in case of composites the ratio of material is maintained but it can not be in case of synthetics...e.g of synthetics is plastic, or composites is concrete

It is 0.25
