An artist creates a right prism whose bases are regular pentagons. He wants to paint the lateral surfaces of the prism. One can of paint can cover 30 ft2. How many cans of paint must he buy if the height of the prism is 15 ft and the length of each side of the pentagon is 5 ft?

explanation:

carbon can form so many different compounds not just with oxygen

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

yes it is weird but true

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
