challenges using and managing renewable energy sources, could be making sure that they aren't over used, and that they have enough time to reproduce themselves before we again divulge. For example, trees are cut down to create things for human use. If we don't replant trees, but just keep cutting them down, eventually they will run out, leaving us without oxygen. As for non renewable resources, we have to be very careful not to destroy all of what we have, because it cannot form again by itself..

I tried this and it said it was incorrect. Is there another way?

Yes

YEs

8+11+31=50 for 3 weeks and to get 150 cans you would need to collect for 6 more weeks.

what about inventing an electronical way to catch rodents?

yes

thank you for your help it is greatly appreciated.

y = x ^ 3

well i know that one of the answers is the Arizona Caridinals

CorrecT!

A mandolin is a musical instrument in the lute family (plucked, or strummed). It is descended from the mandore, a soprano member of the lute family. It has a body with a teardrop-shaped soundboard, or one which is essentially oval in shape, with a soundhole, or soundholes, of varying shapes which are open and are not decorated with an intricately carved grille like the Baroque era mandolins

well he was a child prodigy because he learned music at a young age and was succelssful and genious just listen/ take a look at his music. he also created various works for different groups of instruments such as songs only for a few woodwind instruments called chamber music.

time signatures, note divisons, and counting out beats and subdivisions of beats.

well the pentatonic scale duh? its used in memorizing music and its the first scale kids know. there is a kids song that uses the pentatonic scale but i cant think of it right now.

all it is is an extension of th staff.

Thank you

Would it be: To find the mean you would meausure the size of 4 students heads, add the calculations together and divide that by 4?

Mr.L is that correct?

Why multiply by 1.0835?

They need to be 2 words but still compounds

i looked it doesnt help at all!!!

thank you so much Ms. Sue

DrBob222, the pka value would be 9.26,. but how would you figure out the concentrations of the acid and conjugate base (M). You would have 0.124 mol NH4Cl and 0.07416 mol NH3, but how do you get them to concentrations. I know I could divide each by the total volume, but the problem does not give that info. Help Please

HOPh + OH- > H2O + OPh- (0.1L)(0.700 mol/L)= 0.07 mol HOPh (0.07L)(1.00 mol/L)= 0.07 mol NaOH I 0.07 0.07 0 C -0.07 -0.07 +0.07 E 0 0 0.07 (H3O+)= mol HOPh/mol OPh- X Ka= (0 mol/0.07 mol) X 1.29 X 10^-10 I'm stuck here because the 0 makes the problem unsolvable.

Oh wait I got an answer is it pH= 8.86?

Thanks for poiting that out. I got a pH of 9.03. My only question is why the pH isn't acidic if it is a strong acid mixed with a weak base?

a. special I wasn't sure though

STOP answering my questions thats what i am asking you

what is mu and vi? the last part 1/2*1/mu*vi^2

Well, for your major it will not be needed. However, some schools require a certain score on the math section of the SAT. If you do not meet the minimum score, you may be placed in a class like college algebra. So, if you have not taken the SAT and scored at least a 420 (dependent upon school), then you may want to take trig because it would help you on the math section of the SAT.

Thank you so much for explaining :)

This did not help, I am still confused.

i know that i tried it but i keep getting 125

Somewhat, but still a little confused about the individual cases. Thanks though.

It's a factor that motivates a course of action. This can be financial or non-financial and it encourages someone to behave in a particular way. For example, a boss may offer a pay raise or promotion to an employee for completing a certain task in a timely manner or thinking up something new for business purposes.

So it's polar and H bonds with water and methyl alcohol, but not hexane?

Ok, thanks though.

We used a flame ionization detector (FID)to get a gas chromatogram of an unknown to identify.

Infrared spectroscopy is termed a “chemical fingerprint.” It allows one to determine the presence of certain compounds in a sample by determining possible peak assignments through comparison of experimental and literature frequencies. Ethanol would result in an H-bonded –OH stretch (3600-3100 cm-1) and a C-O stretch (1300-1000 cm-1). Correct?

Thanks

how do you get 300 and 500?

ohh i see.... thanks :)

sorry instead here it's (3x-1)/(x+5) +(32)/(x^2-25)=(3x+1 )/(x-5) yes I know that it will factor out to be (X+5)(x-5) but the thing is isn't 3x-1 only multiply by 1 since it already have (X+5) as its denominator?

I don't have text book I asked a friend for the questions and they couldn't help me

throw

I could help you out, but you did not give the transactions.

Thank You Ms, Sue

The only pattern I see is 7*2=14 and 14*2=28 so each term is multiplied 2 times. But when it gets to the 7 don't you have to divide the term by 2 because you can't multiply it? so the answer would be 3.5 and 1.75. right?

Okay, that's what I thought. But I have to enter my answers onto an online service and it says my answers are wrong.

Thank you Ms. Sue again. I just needed to change the answer to a fraction.

Thank You!

I'm still not understanding how to do this problem.

Thank You!

Thank You both!! I have another question that is similar to this one.. An accountant earns $3180 per month after receiving a 8.5% raise. What was the accountant's monthly income before the raise? Round your answer to the nearest cent. What i thought you did was 3180*8.5%=270.3 3180-270.30=2909.70, but it says its not correct. Any ideas on how to do this?

I understand how to set it up I just don't understand why its 1.085. I thought it was just .085. why is the 1 there?

This doesn't help at all MS.SUE

No I need the names of the settlements. I have 1. Plymtoh 2. Roanoke 3. I only need 3 too.

That isn't a settlement that is a city duhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh. MS.SUE u r dumb

I am waiting....

This is the exact way that it is written on the homework paper. Clue 1: I am greater than 15 and less than 40. Clue 2; if you double me, I become a number that ends in 0. Clue 3: 1/5 of me is equal to 5.

Sorry I didn't realize I missed part of it.

The answer on that link would be 25 and 25 doubled isn't less than 50 it is equal to 50.

Thank you!

Well that's what I did and when I submit the answer it says that it is not correct.

That is exactly what I thought, but when I put it in the answer box and submit it, it says that it is wrong.

So what do you mean by y in terms of x? I solved x^2 + (y-2)^2 = 4 and I got y^2 - 4y + 8 = x^2 ?

Thank you very much for explaining.

So the domain would be all real numbers greater than or equal to 0?

Ok so here's a similar problem. The manager of a weekend flea market knows from past experience that if he charges x dollars for a rental space at the market, then the number y of spaces he can rent is given by the equation y= 200-4x. Is this correct? Slope represents the relationship between amount charged per space and how many spaces he will rent. The more he charges, the less he will rent. y-intercept represents the # of spaces he can rent x-intercept represents the amount of money he can make or charge

Is there supposed to be a 1 + in front of the f'(2)?

What do you mean subbing? I thought that was the final answer? In the book it leaves f"(x)= - cos x for f(x)= cos x

Oops, sorry about that. Do you mean this: sec^3(Pi/4) + sec(Pi/4)(tan^2(Pi/4)) = 3*sqrt(2)

what does the sinai peninsula connect?

????? I have a teset tomorrow and need to know!

oh well i think that it connects egypt and israel...

a.) convert 15.61 kPa to Pa by muliplying by 1000. So 15.61*1000-.506m*106kg/m3*9.8m/s2

Then for b.) same thing except distance will be negative. So 15.61*1000-9.8*1060*-(negative)1.3

Did I do the derivative part wrong? Should it be: 5y^4 + (x^2 . 3y^2 + y^3 . 2x) = (x^4 . 1 + y . 4x^3)

How do you solve this problem? V = Bh Solve each formula for the variable shown in RED. In this problem the variable in RED is the letter B.

Thanks for your help! The only thing is that the AL and FE need to be switched around and then I got the correct answer. There is a picture that I forgot to post that has Aluminum by the 75.5 and 30 next to the Iron. Thanks again!

you have time to say this but not to answer other peoples questions! We need help!

thank you!

Thanks a million!

Given two spheres, if the volume of the first sphere is and the volume of the second sphere is 36 , which is the relation of the second radius to the first?

You are absolutely right. Cheating is horrible but I've tried and tried to find the answers but they aren't in my book. I'm supposed to already know them. I just need help. Guess I need to reread my five other books and try to figure it out myself

I apologize again. I shouldn't try to cheat I need to do the work myself. Sorry if I upset you or brought shame to Pennfoster. My mistake I need to do my own work and not have any answers given to me.

I'm sorry, but I'm confused on the 2nd part?

Hi, I have the same problem, but could you show the solutions in terms of "Properties of Logarithms" Thanks, Chelsea

When I solve the part in the second post I get 46.67 sec. When I solve the quadratic I get -1014.14 and 1071.28 I arranged it as -0.5at^2 + 28.57 - 666 = 0 Also, I guess the wording of the question with "magnitude of the resulting constant deceleration" made me think the answer should be acceleration in m/s^2 but this is not the case as the answer is time in seconds. Why is this?

1.) Soaps and detergents are the outcome of a fat and strong base reaction. Triglycerides break down in the presence of a strong base to form Na+ or K+ salts of the fatty acid. This reaction is called saponification “the making of soap”.

He also put this on the board, but I don't know how to use it, as I plugged in and didn't get the same numbers. [avg(2)+avg(3)+avg(4)]total population
