I am running an experiment to determine the effect of temperature on the eating habits of a certain snail species.The first time I ran the experiment,I found that increases in temperature increases the amount of food the snails consume.The second time,food intake decreases with higher temperatures.Can you please help me identify 2 steps that I could take to resolve the disagreement of the 2 runs?! :D

Ok, I'm in 8th grade and in Algebra 1. I don't really think the should have put me in here without letting me go to Pre Alg. first because I'm not the worlds greatest mathmatician, but what ever heres the problem:
The local market is having a sale on whole fish. The prices are as follows:
You can buy an albacore and a barracuda for $21.
You can buy a barracuda and a carp for $24.
You can buy a carp and a dogfish for $32.
You can buy a dogfish and an eel for $37.
You can buy an eel and a flounder for $31.
You can buy a flounder and a gar for $25.
You can buy a gar and an albacore for $26.

Determine the cost of each individual fish.

Now I'm not asking you guys to solve it, just to tell me how to solve it, because to be honest I'm lost. lol First person who can help me solve it gets 10 points! Thanks in advance.

I just want to know the algebriac method, I know the easy way but I am not sure these are correct.


The Binary system is udes for computer programming. A binary number consits of a sting of digits that are eigther 0s or 1s.

a) If a string of Binary code is 5 digits long, how many binary numbers are possible if the first digit is 1.

The answer I have is 16 which I got from 1*2*2*2*2 but I would like to know the algebriac method for this question as I am not sure this is correct.


b) How many different binary numbers can be represented by a string of binary code with 5 digits if the first digit is 1 and the last 2 are 0s?

I have the answer 4 which I obtained from 1*2*2*1*1 but I would like to kknow the algebraic method as I am not sure this is correct.

All that is needed is finding the derivative and simplifying the answer. After attempting it I couldn't come up with a sensible answer. 3x-2/(2x+1)^1/2. (The denominator is the square root of 2x+1).
