Income tax for some states is computed by taking 3% of the excess income over $3,000 plus 1% of the first $3,000. How much tax is charged on a income of $12,000? 12,000 1 percent on first 3000 3 percent of (12,000 - 3000) I'm trying to figure the relationship between income ...

ho do you calculate final temperature? anyone please help thanks that's a little vague. Are you dealing with ideal gases? If so you would use the formula PV=nRT P = pressure V = volume of container n = moles (grams/molar mass) R = gas constant (0.0821) T = temperature sorry ...

Please, can someone help? Evaluate log 1. This is my work up until I have gotten stuck: log 1 1=10^x I can't find a common base for 1 and 10^x. Wow, my apologies, this is algebra, not chemistry. but actually I think they use it in chemistry too... Take the log base 10 of each ...

Next step, multiply both sides by (.01-x) .012(.01-x)=.01x+x^2 gather terms, put in standard binomial form, use the quadratic equation, and solve for x. Your question actually bothers me. You are asking an algebra 1 question in order to solve a very complicated chemistry ...

You divide. It has taken me most of the night but I think I know what your problem is. It isn't chemistry. It is arithmetic and algebra. You apparently don't know how to solve an equation. When we had pH + pOH = 14 and we substituted to give 9.21 + pOH = 14, I had to tell you ...

When I said the second one was worked the same way I meant the concept was the same but the algebra a different. Let's recapitulate the first one so you can see how the units cancel, then we will do the second one your way and see the units don't cancel so we know it isn't ...

ello i need help factoring I haven't had factorin sense Algebra one and now am in Algebra two and our school is screwed up were they shove in a year of Euclidean Geometry and Basic Trig inbetween first two years of Algebra... so i need to factor X^2-12X+35 I can sit there for ...

The chemistry is right. It's an algebra problem now. Solve for X. Chopsticks is right. Expand the denominator by using FOIL, gather terms and solve the quadratic equation.

At what initial concentration would a solution of acetic acid (ka=1.8x10^-5) be 2% ionized? Thanks Responses Chemistry - DrBob222, Thursday, February 12, 2009 at 10:00pm Let's call acetic acid HAc. Then the ionization is HAc ==> H^+ + Ac^- We will call the initial concn of ...

thanks for the help earlier I got one more question X^4-13X^2+36 How do I factor this using algebra not just gussing and checking this times this and what number plus what number gives you these numbers how do i factor that wihtout playing one of those games were you like ...

you can also order the UPCO's Physical Setting CHEMISTRY... it has many helpful equations and it will make it easier to study and understand evrything... plus the book is cheap too.

And it will never be your thing if we give you the answers. a. g = moles x molar mass Remember this one formula and you can rearrange it to give you three things, depending upon the question. a. grams = moles x molar mass b. moles = grams/molar mass c. molar mass = grams/moles...

Chemistry (algebra I problem)
I feel really dumb because I cant figuer out this simple algebra I problem... 84. The diameter of a copper (Cu) atom is roughly 1.3 x 10^-12 m. How mnay times can you divide devenly a piece of 10-cm copper wire until it is reduced to two seperate copper atoms? (Assume there ...

This is pretty basic algebra. Tf[17.75*Ceth +31.6*Cwater] -17.7(Ceth)(7.7) - 31`.6*Cwat*27.1=0 check that. then add the last two terms to both sides. Then, divide both sides by the quantity in . If you really can't do this level of algebra, you need a math tutor now, or ...
