Divide 19 by 42. You should get a decimal. Multiply this number by 100.\n\nYou can check your answer by estimating. Since 20 is about half of 40, 19 should be just under 50% of 42. (It's actually around 45%.)

hmm im not quite in college yet, but i hope to be help.\ndo you know the values for f, h, v, and a?\nif you do, id substitute it in.\nthen square both sides. \nand then solve.

If you can't find the answers online then you're not looking very hard.  I typed #6 into the Yahoo search bar and I got a bunch of explanations.  Do your homework, you might learn something.

Draw a force diagram to help you figure this out.\n\nRemember, perpendicular vectors are independent.\n\nF=ma

Yuo can't solve this.Because it is a formula and not an equation..If u assign some value equal to this formula such as 0 u have the solution.

Basically you just need to look at each number and each letter separately.  See what factor the numbers have in common (for example 4 and 6 have 2 as their greatest common factor, leaving 2 and 3), then see what power the letters have in common (x² and x³ have an x² in common (leaving 1 and x), etc.\n\nJust distribute the common factors out in front and leave the rest inside parentheses.\n\nHere are a few examples from your son's problem sheet:\n4n + 6 --> you have to factor out a common 2 --> 2 (2n + 3)\n4x + 12x³ --> factor a common 4x --> 4x (1 + 3x²)\n3x + 15 --> common 3\n-6y² -3y³ --> common -3y²\netc.\n9c³+15c --> common 3c\nxy²+x²y --> common xy --> xy(y + x)\n\nI left some out, but I think you should be able to explain it to him now.

http://www.gateways2learning.com/Algebra/Algebra.htm\n\nAlso try here.......\n\nYou may want to reconsider having it solve the answer for you, always know how to do the breakdown, it will help you to know "how" to go about it when you take a test.\n\nGood luck.....................

Trying to get someone to do your homework for you?  Why don't you take a first stab at it and post the results... \nIf you then still can;t get it, I'm sure we can help!\n\nBut you'll learn a LOT more by trying it yourself FIRST!

Its tricky work, i need digrams to explain to you so your better just following this link, I think it will help you out.

ok so take the y out, so then the problem will be 3x-6=0, then put the -six over to where the 0 is, so now its 3x=6 so just solve for x, and its x=2

I'm trying 2 figure out how 2 chick this question.

Okay.  This can be a little tricky if you dont see how to set it up.\n\nwe don't yet know the length, so lets call that x.  Since we all know there are 4 sides to a rectangle lets set up the equation like this.\n\n36 = Perimiter.  Since the length is 4 ft longer lets write the expression to show that.\n\n36= 2(4+x)+2x\n\nx = the width, and since theres 2 lengths and 2 widths, multiply them by two. now multiply out.\n\n36= 2(4+x)+2x => 36=8+2x+2x => 36=8+4x\n\nnow its simple algebra\n\n36-8=4x\n28=4x\nx=7\n\nsince x=width,         width =7 ft\nsince x+4=length     length = 11 ft\n\nnow find the area. This is the easy part.\n\nArea= length x width\n\nA= 11x7\n\nA=77 ft^2

whats the equation or formula u need help with?

I figured it out... the answer is 1/(13*(2-3x))\nIf you need an explanation tell me

This is an impossible figure as by your own figures ΔABC is equilateral with AB = 2AL = 10\nBC = 2BD = 10 and\nAC = 2AE = 10\nso AT = 2/3 * BT = 2/3* 5√3\n= (10√3)/3\n≠10

i think u typed the question wrong, can u please correct it and if u have 2 unknowns, please give 2 equations, else u cant get a definite solution

a=(v-c)/t\nMultiply both sides by t\nat = v-c\nAdd c to both sides\nat + c = v\nSwitch sides so that \nv = at + c
