you can't take the square root of a negative number (or if you do the result is imaginary). this is because two negatives multiplied make a positive, same with two positives. so set the whole thing equal to zero and solve for x.
You can look at common multiples. The closest one is 12. 0, 4 seconds, 8 seconds, 12 seconds 0, 6 seconds, 12 seconds If you want to make it more complicated (I'm not sure your skill level or the level of the material) you could find the frequency of each
Your question has some typos I think ("divided 7 by?") I'll do a best guess. "Difference" means subtraction. "a number" is another way of saying a variable, or x in this case. "divided by" is indicating division, or a fraction in this case. "equals" is
Aw yes I led you astray on two fronts (don't tell Writeacher, mistakes are not allowed here). But seen as you did it the same way I did, Sharon, perhaps I can explain the trap we both fell into. (Steve did an excellent job himself, but it never hurts to
Side note: "Indian" is not the same as "indigenous." Indians live in India. The Cherokee are an indigenous people of North America. First nations, native, aboriginal, indigenous or simply Cherokee are all much better alternatives that continuing a

is that 54 km/h? i'll assume so i will also assume this is constant velocity and not accelerating you can't compare apples to oranges (or in this case seconds to hours) so you'll need a conversion. how many seconds in an hour? 60minutes in an hour and 60
I have to agree with bonjo. This question is tricky because if a molecule is chiral, it is irrelevant whether it can rotate around the axis or not, like as presented in this case. HOWEVER, this molecule is not chiral to begin with, so it is never chiral.
It can be difficult to come up with formulas from word problems. Your going to add some weight of the first alloy and some weight of the second allow to get 40 grams. let x be the weight used from the first alloy and y the weight from the second. so x+y=40
cost = $17.50 @80 scoops => 80*($0.90)=$72 revenue $72-$17.50=$54.50 profit @98 scoops => 98*($0.80)=$78.40 revenue $78.40-$17.50 = $60.90 profit $60.90 - $54.50 = $6.40 profit went up by $6.40 $60.90/$54.50=1.1174 profit went up by 11.74%
for every 3 you buy, 1 of them is free. so the "deal" is 1/3 off, or 33.333333% off, rounding to the nearest tenth 33.3% just like "half-off" is 50% off, which is the same as 2 for 1 (because for every 2 you buy you get 1 free, in other words you get half
ok well then lets see. if the selling price were $100 and the markup was %50 based on that that implies $50 of profit, meaning the cost is also $50. so if the cost is $50 and the markup is $50 then the markup based on the cost is %100 (meaning you are not
you want to sell the shoes for $79.95, and you want to make 55% profit that is you want to get the shoes for x dollars and then sell them for 55% more (or more) so that the final price is $79.95 so (x cost)*1.55=$79.95 solve for x $79.95/1.55=$51.58 you
pretty broad question. have you read any of Lewis' works? what are the guidelines, what sort of thesis are you supposed to write...is it a biography? or are you arguing that such and such event in his life influenced some work of his?
by definition work only occurs when something moves...so no work was done or in other words 0 J. of course in reality they used energy to do nothing, but it didn't qualify as "work" because nothing was accomplished i guess
holy moly no need to post this 20 times :P so the problem is you can't add or subtract radicals that aren't the same, so you have to modify them so that you have the same numbers inside the radicals the easiest way to visualize this sort of thing is to
to convert grams to mols you need to know molecular weight from periodic table of each of the elements in the compound. C = 12.011 g/mol H = 1.008 g/mol N = 14.007 g/mol 0 = 15.999 g/mol S = 32.06 g/mol each of these numbers indicates how much 1 mol weighs
from the internet: W = V^2 / R 12v Battery -> C(t) and 3ÃŽ© R in parallel -> back to battery so the resistor and the capacitor are in parallel and you want to know the overall resistance so you can figure out the power needed? well this website gives
oops sorry not 3*4!, 4!*4!*4!. parent is right, i'm wrong
I don't remember the formulas or anything, but just thinking about it: for the first guy you have 4 heads X 4 torsos X 4 legs 2nd guy has 3 heads X 3 torsos X 3 legs then 3rd has 2X2X2 last guy has 1X1X1 so 4X4X4X3X3X3X2X2X2X1X1X1 in other words
Unless there is some other fact missing, I would guess they are conflating selling price and cost, and the answer is 50%...
I assuming it's saying what do they sell it at, when they markup the cost they paid for it by 39%. If that's the case $24.30*1.39=$33.78/oz
Unless I'm missing something, I don't see how this question provides enough information to answer it. Is this a smaller part of a longer form question? Is this based on an economic theory perhaps?
P1V1/T1=P2V2/T2 1atm*(3m*5m*2.8m)/293K=P2*(3m*5m*2.8m)/1273K P2=1atm*1273K/293K P2=4.3447atm (1 scientific figure..so 4atm)

Assuming the compartment has not changed shape during the fire...the volume is the same, whether or not the pressure changes. 3.5*5.5*3=57.75m^2 trick question methinks
Is it not 30kJ/g*5000g? 150000kJ (150MJ)
Rephrased, how many mols of solute are in 400mL of 30mM solution? 0.4L*0.03mol/L = 0.012mol How many mL of 3.0M stock do you need to get 0.012mol of solute? 0.012mol*1L/3mol = 0.004 L 4mL of 3M stock (and you would add 396mL of solvent to finish the 400mL)
8th amendment bars cruel and unusual punishment. for 2, it would be c. "professional" usually encompasses any profession, which is often something someone goes to advanced school to do. educational would just cover teachers.
Is this an essay question? Mostly answerable in your textbook?
a regular parabola with vertex at 0,0 is y=x^2 what the question is asking is to move the parabola 5 units left you can move any formula horizontally by replacing x with (x+/-n) where number is the amount you want to move it. moving right means you do x-n
how many possible ways can three students sit in ten chairs? 10!/(10-3)! 10!/7! 10*9*8 This makes sense b/c there are 10 spots for the first students, 9 spots for the second student and 8 spots for the third. How many ways can 3 students sit adjacent? 123
