I have scanned the word problem and the scratch work I did on it.

My hand writing is horrendous so I am going to retype the answers I got here:

x=# of cookies-plain
y=# of Iced cookies


f(x,y)=1.5x+2y
x>0
y>0
.1x+.15<15
x+y<140
x+.7<110 which equals x<109.3
.4y<32 which equals y<80


(x,y) 1.5x+2y f(x,y)

(0,0) 1.5(0)+2(0) 0
(30,80) 1.5(30)+2(80) 205
(109.3,407/15) 1.5(109.3)+2(407/15) 13093/60
109.3,0) 1.5(109.3)+2(0) 163.95


Here is the link to the graph I needed to make to find the above information: http://img212.imageshack.us/img212/1553/graphlj8.jpg

I really need someone to check my work. I been over it a dozen of times and I still feel it is wrong. Please check it and tell me if I did anything wrong

I asked this question a couple of hours ago and got confused by all the answers, so if you know, can you carefully describe why for me? This is what i asked before...

This is in chemistry and we have been doing all sorts of molality equations and so forth and have just been given this problem and not quite sure i follow.

We are asked in question 4:

Part A
What are the six types of radioactive decay?
I found that they were...
α emission, (alpha)
β emission (beta)
γ emission (gamma)
positron emission
electron capture
spontaneous fission


But then it asks in part B of the question...

Complete the following nuclear equations
a. proton -> neutron + ?
b. neutron -> proton + ?
c. proton + ? -> neutron

am i supposed to use one of the following types of radioactive decay? thanks for the help and assistance!
