50 * 6 = 300ft

It's actually third grade math. They are learning to round up or down numbers to the tens. So the problem regarding the 60 marbles is to determine if you would round up or down the number 60. I am thinking that since it's already a value of 10, that the least and greatest number of marbles would be the 60 as the answer. Thanks

I am a relly bad writher please help me.

Im not sure, but I think its Mesopatamia.

Ball A's original momentum is .00114 kgm/s. The change in Ball A's momentum would be .006 kg x (.19 - .08) m/s, correct? Ball B's change in momentum would be .009 kg x (.11 - v) m/s. The momentum of Ball B would be .009 x the change in velocity from the previous question. Ball B's speed would be the original velocity minus the change in velocity.

just do this when solving problems like this....Parentheses,Exponent,Muliply, Divide,Add,Subtract. The answer to your problem is 17

ok, thanks

Thanks!!

what is a plat tectonic

it equals 43,000 so I would write it 4.3 *10^4...IS that what you're asking?

Well the sinking of the british liner Lusitania was the main reason we entered because there were like 100 or more American's on the ship. Wilson demanded safety to passenger ships and Germany complied sort of. The germans also sabotaged Black Tom and the Kingsland explosion where the US was shipping war supplies to allied countries...also, the fact that Germany sent what is now known as the Zimmerman Telegram offering an alliance between Germany and Mexico so that Mexico could have the US also brought us into the war.

40,000 + 3,000 ___________ 43,000 to determine the exponents you put the decimal after 4. Then count how the spaces to the right after the decimal. your last decimal will be after the 0 = 10^4......does that help?

So far this is the equation I have 0.54= log(x/10) and I cant solve for x...I forgot how to do it correctly

This is all they gave me: You need to produce a buffer solution that has pH 5.28. You already have a solution that contains 10 millimoles of acetic acid. How many millimoles of solid sodium acetate will you need to add to this solution? The of acetic acid is 4.74. Then they gave me this equation: pH= pKa + log (salt/acid)

the US was lending war materials to allies under the lend lease act to avoid interallied debts...

OMG, Thank you so much! I dunno what i was doing! Thank you Thank YOU!!!

Thanks! I feel pretty stupid now.. I was also curious about predicting products. How on EARTH would you do that when there are so many products?

why do sodium chloride and sodium nitrate all impart the same color to the flame?

Is this a riddle?

Well, I think it's B.

You need to find out what's x and what's y.

so the electic field outside the sphere is 9*10^9 p (r/a)^2/a^2?

I am not sure how I am supposed to do it. does that mean the limit is 6?

Radisson et grille à la maison?

Thank you so much that really helped me

I think the answer is b am I corerect?

I really need help with my Spanish crossword puzzle. Please tell me where i could find a translator online right now. Thanks a whole lot!

Given the follwoing solubilities, calculate the value of the Ksp for each compound: b) Zinc carbonate, 3.87 x 10 - 6 mol/L

I got 5.7 x 10 ^ - 6 why is this incorrect:(

It is incorrect, where , sadly I cannot say:(

Hmm.. I will check over if I typed in the correct numbers and I will let you know

For simplicity, all answers should be correct to two (2) significant figures and not expressed in scientific notation. The above was also found next to the question

Multiply by -1 on both sides?

Regarding the table, trial 1, trial 2 and trial 3 are not so neatly written but they should be shifted a little to the right

Here are my results: *Initial volume of HCL(mL) Trial 1- 0.0 Trial 2- 2.51 Trial 3- 4.95 Trial 4- 7.4 Trial 5- 9.9 *Final volume of HCL (mL) Trial 1- 2.51 Trial 2- 4.95 Trial 3- 7.4 Trial 4- 9.9 Trial 5- ? *Volume of HCL added (mL) Trial 1- 2.51 Trial 2- 2.44 Trial 3- 2.45 Trial 4- 2.50 Trial 5- ? How would I get Final volume of HC (mL) and Volume of HCL added (mL) for trial 5?

When I have the table filled out, what would I need to do in order to calculate the solubility product for calcium hydroxide? The following is what I have in mind, please tell if I am incorrect or correct. Ksp = [Ca+2][OH-1]2 You should have an average value for the amount of H+ that you put into solution. For every 2 Mol of HCl added you neutralize one mol of CaOH2 right? Take the number of mol of hydroxide neutralized and divide by the volume of solution this will give you molarity of the CaOH2. You know from the stoichiometry that there is 2 times as much OH- present as calcium. So.. plug these numbers into the equation for the Ksp and you should arrive at your answer. Ksp = [molarity of OH- / 2 ][molarity of OH-]2

I have one last question. Conduct a search to determine the actual value for the solubility product of calcium hydroxide. Compare your experimental value to this value by determining the percentage difference. How would I use the percentage difference formula in this case to arrive at the answer?

I don't understand how you get x^2=50/18

*CORRECTION 0320C is supposed to be 0.320C

how do i figure that out?

I ahve the identical questions...Is your book Modern Chemistry?

Im really confuzzled to! I have no idea what my teacher is going on about! What on earth does "the big idea of energy" mean? HELP!!!

Thank you very much MS.Sue

I need help locating websites that will help my chid with a science project. She is supposed to create an investigation that will test the question:"Does elevation affect the speed of an object?" PLEASE HELP!

Does it mean the name of the one who is presenting it and the references used? and is it written on the first page or the last page? Because i wrote my name on the first page :( please help... Thanks!

what if i got all the information from internet? Thanks for help!!! i am so confused....

Wow all the negativity. I am also working on the same topic and I am also an axia student as well I am having troubles as well with this assignment. All I can say honestly is work through the assignments patiently. I start all my assignments on mondays so by the time this one is due i would have gone through the text 3 or 4 times before i would have turned it in. Eventually this would have knocked information in my brain. I do not this it is anyones place to use the negativity in this type of forum since most of us are just learning as well. One day that person needing help now will give you help later so be nice! Other than that I would read chapter 11 a few times it might spark an idea.

Tell me if this is right For the first step this is what I am doing m=250.0kg c=0.028kcal deltaT- 328-20?? Is this correct this gives me 2156 Am I on the right track for the first step?

I know.. I am just making sure I am on the right track.. I am going to try and finish it now.. do you mind if I send you my answer and you tell me how I did?

okay is this correct I took 250.0 * 5.5 = 1375 1375+2156=3531kcal

I mean how it effects the acid-dissociation constant(Ka). How does water effect the Ka value of a weak acid?

THANK YOU!!!!!!

go to google and type in maps of mexico

I would have to agree with the person who says that their assigned reading didn't help. I don't even read my assigned reading anymore, mainly because i find updated facts online. All of my homework has been based on other peoples opinions and homework that have been done, but at the same time i REFERENCE them

Benjamin Franklin believed God was on the colonists side and that he would help them win the war :)

I am actually online right now for this exact problem "how were the puritans different..." it's driving me insane!

To describe the differences between types of light like visible and x-ray, scientists often talk about the length of the light's waves or "wavelength." The various types of light that make up the electromagnetic spectrum differ in the length of their waves. However, this doesn't mean the entire length of the wave train. The length of a light's wave or the wavelength is the distance between two nearest peaks (the highest places) or two nearest troughs (the place where it dips the lowest).

I did that and I got 901.35 for both. So is my answer of 6009 correct?

Get it into y=mx+b form(slope-intercept form)

what if i wanted to graph the equation? how would i do that?

thanks damon, chopsticks and ms. sue. you helped me alot!

thanks!!!!!!!!!!!!

I think it's somewhere between 0.56 mL and 0.62 mL, hope that helps!

On a saturda morning there are 13 games of rugby being played at a park. each game includes 30 players, 1 referee and 2 line unpires. If 700 people were at the park how many are players or offials?

A diving bell is lowered to a depth of -124 metres, i.e 124 metres below sea level. If it rises 38 metres and then drops a further 65 metres from this point what is its new depth?

Thank you, it really helped. :D

So do you go ; 42x12?

The number 4 is in the hundredths place in the decimal 0.045. The first number after the decimal is the tenths place (0), the second number after the decimal is the hundredths place (4), and the third number after the decimal is the thousandths place (5). Is that what the problem was asking?

Try making notecards with some of the most important information and vocabulary in the chapter. Use different colored index cards and highlight the words/phrases/equations that you have the most difficulty with. This is especially helpful if you are a visual learner - colors can help you remember.

Remeber the verbs for the verb "comprare" (to buy). Since "comprare" is an -are verb, recall the verb endings: Io: -o Tu: -i lui/lei/Lei: -a noi: -iamo voi: -ate loro: -ano Now, all you have to do is plug in the conjugated verb between the subject and the noun. For example, the first one would be "Noi compriamo un dizionario di sinonimi."

In order to conjugate(ex. comprare), take away the -are. So now you have compr-. Looking at the endings above, plug them into the stem of the verb so that the subject of the sentence matches the verb.

You have to use substitution for this problem. So, let u=(ln r). Then du=(1/r)dr. Now plug in u and du into the equation. This yields the integral of (sqrt(u)), which can also be written as the integral of u^(1-2). Now just integrate and plug (ln r) back in for u.

I don't have much, but i am sure i can find on

I'm also taking this course and having trouble finding the information...what are the sources you used to answer these questions?

Don't see how you get 5? How do you square 4? 4*4 = 16 correct? So then how can R = 5? I don't get it...Thanks by the way for the graph!

I think I see what you are now talkin about! is this correct? D = sqrt ((x2-x1)2+ (y2-y1)2) -4- -4 = -8 1- -5 = 6 Half the distance between the two given points d = diameter = sqrt (82 + 62) =sqrt (64+36) = sqrt (100 = 10 Radius = 5 NOW i need to know how to put this in standard form? If this is correct?

Would this be considered standard form? (4-0)2 + (-5- -2)2) = r^2 (4-0)2 + (-5- -2)2) = 5^2

Thanks for all your help! You really explained this topic well! Thanks again, and have a terrific weekend!

What do you mean by "OK if you are teaching? I was just wondering?

I am going to try to. How can I graph this so I can see it?

This is what I came up with, but I am still having a hard time graphing it. Is this correct? Mid-point formula = (x1+x2)/2 (y1+y2/2 x = (4-4)/2 = 0 y = (-5 +1)/2 = -2 (0,-2) is the center??

I did it! The center is (0,-2) on the graph after tracing the circle. Now i need help with the length of the radius of the circle. (Note that this is a distance.) Give the exact answer? What do I do here please? Thanks!

Oh ok! Thanks again! You really know your stuff! Have a great weekend!

Thank you! I got many more of these to do, so just wanted to make sure my first one was correct! Thanks!

Im not getting it.

Simplify the expression. Assume all variables represent nonzero real numbers. -10b^5c^9/2b^5c^3

Thanks I found it.

Yes I will need the practice without a doubt! Now you say the The horizontal asymptote is y = 0 What about the the y-intercept and the vertical asymptote(s)?

I got 0 for the y-intercept why -3??? and The vertical asymptotes are x = -2, x = 2 ????

Where are you getting 2/3 from????

How can i improve this essay?

Thank you so much!

So static: 0.73 and kinetic: 0.57, thanks!

YES, that is correct!

it should be something that includes (x-1000) . it would be something like this : (x-1000) + x = 4400. im not sure. but its a close guess.

Thank you Ms. Sue.
