Wood & bone.
Prime factors are 3 & 5. You should have no difficulty in calculating the composites, if any...
There are infinitely many numbers, and these comprise infinitely many primes and composites. It is not possible to list them all.
Number of primes = 4 Number of composites = 5 Ratio of primes to composites = 4 : 5
The population of Scaled Composites is 200.
Scaled Composites was created in 1982.
Firehole Composites was created in 2000.
Combination of two or more materials
Composites in nature play a crucial role in providing strength, flexibility, and durability to various living organisms. For instance, wood is a natural composite that gives trees the structural support they need to grow tall and withstand environmental stress. Additionally, composites found in bones and shells help provide protection and support to animals.
Fiberglass is not a naturally occurring material. It is made of plastic composites and takes hundreds of year to degrade.
