let me retype the question. Sorry for the scribble. 1/2 X 1/2 answer in simplest form. must show work. thanks
desperately seeking help. work must be shown. answer must be in simplest form. Thanks 1 1 _ X _ 2 2
There are multiple choices for the answer to this problem. They are a) 1/5 b) undefined c) 5 d) 5/7 Thanks again for both of your help
Sorry Reiny, The question is 11-6/7-7 I thought the answer was 5/0= undefined. Can you please let me know if I am wrong and show the work so I can further understand your answer. Thanks Reiny
Thanks Reiny, Yes, I spotted that it dosen't work for any run of primes, but it does up to 9. I'm afraid i don't really follow your explanation! An answer for dummies maybe? Charlie
I have to find the relationship between these sequences, and express a generality. Could you help please. 1 + 3 + 5 + 3 + 1 = 3^2 + 2^2 1 + 3 + 5 + 7 + 9 + 7 + 5+ 3 + 1 = 5^2 + 4^2 1 + 3 + 1 = 2^2 + 1^2 I'm thinking sum of consecutive primes can be expressed in squares? Th...
It's too hard. You should give up now
A compound containing 3 atoms of carbon and 8 atoms of hydrogen is combined in a reaction with oxygen molecules. The two end products of this equation are carbon dioxide and water. Which chemical or element will have the largest number of moecules?
What was the purpose of the phenolphthalein?
I'm reposting this, because Mathmate's answer hasn't directed me to the WHY? part of the question. Any prompts appreciated. The product of any two (whole) numbers each of which leave a remainder of 1 on dividing by 7, also leaves a remainder of 1 on dividing by 7....
