ok, Thank You! :)

I would construct the building within 200 m from the side near to the logging area and the road across the reserve within 110 m from the side of the deforested pastureland. This would help reduce the problem of parasitism by the brown-headed cowbirds by separating them from the woodland birds. Because the road would be built within 110 m from the side of the deforested pastureland, the female cowbirds, the more parasitic sex, would no longer be able to gain access to the nests of the woodland birds. The division of the two species would ultimately help sustain the population of woodland birds, thus achieving the major goal of the reserve.

I would construct the building within 200 m from the side near to the logging area, and I would construct the road across the reserve within 110 m from the side of the deforested pastureland. Constructing the building within 200 m from the side near to the logging area would help the ecosystem as a whole by not destroying any more of the natural habitat. Constructing the road within 110 m from the side of the deforested pastureland would help reduce the problem of parasitism by the brown-headed cowbirds by separating them from the majority of the woodland birds. Because the road would be built within 110 m from the side of the deforested pastureland, the road would serve as a sort of “barrier,” and the female cowbirds, the more parasitic sex, would no longer be able to gain access to the interior nests of the woodland birds. Since cowbirds usually forage in open fields on insects attracted to cattle and other large herbivores, they would still be able to survive near the deforested pastureland, where there is more edge habitat and open land for cattle, horses, and sheep. The division of the two species would ultimately help sustain both the population of woodland birds and the overall biodiversity of the ecosystem, thus achieving the major goal of the reserve.

What about the bike of yesterday? Like the very first one ever?

Thanks a lot.

What is the simple subject and simple predicate in the sentence The first movies were different from today's films. I said the simple subject is movies and the simple predicate is were different. I this the correct answer?

Yay! Thanks Liandra!

What is the smallest part of a compound?

Is this right??

Sorry it should be 8.58 * 1.020/ 1.584= Answer: 5.525 m^3 Is that right now

Thanks for all the help DrBob I really appreciate it

P(5.00L)= .446 mol(.0821)(292K) It would look like this right then do I just multiply it all together and divide by the 5.00 L

.985(V)=.177(.0821)(296)= Same thing do you multiply and then divide by .985

Okay I see where I went wrong

-281.0 kJ ( 1 Joules/ 1000 kJ)(1 calorie/ 4.184 Joules)(1 k cal/ 1000 calories) is this the correct set up

235 grains (0.0648 g/ 1 grain)(1000 kg/1 g)= 2.52 X 10^3 ft/s (1 m/3.28 feet)= is this the correct set up then where do i go from here

sorry it is supposed to say When 23.6 of calcium chloirde CaCl2 was dissolved in water in a calorimeter, the temperature rose from 25.0 degrees C to 38.7 degrees C. If the heat capacity of the solution and the calorimeter is 1258 J/ degrees C, what is the enthalpy change when 1 mol of sodium nitrate dissolves in water? The solution process is CaCl2 ----> Ca2+ + 2Cl Delta H=? Sorry I read the wrong question my fault I appoligize

so CH4 = -74.87 and C2H6 = -84.68 what do you mean by take 80% and 20%???

what do you mean by proportions???

distance is 998 million km what is veloctyoflight

frequency = speed of light/656 nm how do you find the speed of light

sorry I copied the wrong problem it is supposed to be: 521 m/s not 6210 m/s 6.63 X 10^-34/ (? kg)(521 m/s) How do I get the kg for this problem

3.01 x 10^23 ???

so that website means that i need to use 1.6726 x 10^-27 kg why that number

yes I know how big that is but I figured that you had 2 atoms of 6.02 x 10^23 so I divided by 2 to get the mass of 1 mol which is 3.01 X 10^23... why wouldnt you just take the 100 pm and make it into kg.

So rate is the speed of light too

9.98 X 10^11m = 3.00 X 10^8m/s (time) so I converted 998 million km into m now I divided 9.98/ 3.00 and got 3.33 x 10^19 is this correct

yes as you can see i put them in the answer i just dint type them out

well 9.98 X 10^11 / 3.00 x 10^8 = 3326.66

so that equals 2.66 grams/ 1 atom now where do I go from there

Thank you

2.66 X 10 ^-23 (0.001 kg/1 g) = 2.66X 10^-26 that is what I want is kg

so I don't need to go any father I just plug this back into the original problem and get my answer right

6.63 X 10^-34/ (2.66X 10^-26 kg)(521 m/s) = 1.30 X 10^-5 is this correct

so am I solving for Rh This is what the equation should look like right: 1/9= Rh (1/2)-(1/3)

okay so it should look like this 1/lambda= 1.0967758341 x 10^7(3^2)*[(1/3^2)-(1/4^2)] 1.0967758341 x 10^7(9)(.0486) i got 4798394.274

so i got 1/4797297.498

so I did 1 divided by 4797297.498 and got 2.085 X 10^-7

nevermind i got it

i don't know what the resonance description is so i don't have anything yet

to lead nitrate because it is solube

I think this might be right...adjusting the volume for temperature. 273K + 23K= 296K The two possible temperature ratio would be 296K/273K or 273K/296K. I chose the second one. 57.6 ml(273K)/296K answer: 53.1 ml

Can't find it.

I didn't write I cant find it someone else did being stupid and putting my name down as a reply

Sorry I clicked to fast but that is the question and I have four different types of solids to guess from Like Metallic solid, ionic solid, molecular solid, covalent network solid and i don't know which goes with what element

-8+3 = -5 x-5<11 +5 +5 X< 16

well all it asks is name the types of solid it forms and those four our the types of solids. so like LiCl you said it was an ionic compound so it might be ab ionic solid and so on

The question is what is the volume of the unit cell? I don't understand how to get the volume of it

so for this part (g Na2SO4/g solution) = (1.50 g Na2SO4/x g solution). it would be (g Na2SO4/ .065 g solution = 1.50 g Na2SO4/ x .065 g solution ) or did i miss place them

so then i did it wrong... :( is it 142g for the Na2SO4 that needs to be put into there

29.575/455*100=6.5% Yay :)

23.0769 right

ok i know how to figure out the 2nd equation 45.0g CHCl3(1 mols/118gCHCl3)=.381 mols CHCl3 but how do you get molarity. with kg solvent

i think its 216

is it (x^2 - 6) (x^2 - 3) ??

so then its x^2-6 =0 and ^2-3=0 and the don't i put the root sign over the x^2 to get rid of the x^2? and then i end up with x + or - the suare root of 6 = 0 or is that wrong??

so is that it?? simple as that?

but then the directions say variable substitution

alright thanks anyway

92.40 [mmHg]

sorry my fault it is suppose to be molality

wait no its 1.858 Kf(degress C/m)

well actually i double clicked the submit button and it posted it twice... sorry

so it would be 0.085 degrees C = 1.86 C/m (0.1 kg/60 g of (NH2)2CO

so they are the same and both dissolve in ethanol or acetic acid dissolves in ethanol because they are small molecules

is it 60 g of urea for the molar mass and then take the 0.00457/60 and get grams ???

i believe the answer is b

the 65 does not represent the degrees. . .that is why i am so confused on this problem

so it would be .00948/240 right

so change every I2 to H2

I got 88.9 L/(mol*s)

yep

Because most historians back then were white (because blacks werent allowed to go to school). This left many biast things about the slave system and slave trade.

but don't the altitudes have to be perpindicular to the triangle lines?

yes

thanks

Can someone please help me.

no, polar bears are artic animals.

Use the quadratic formula to solve for the variable, p. I would use google or another search engine to find the formula so you can plug all the numbers in correctly.

I fail to see how that relates to math

Exercise 10.1 Variable Cost = = = $3.93 Variable Cost = $3.93 per unit Fixed Costs: At an activity level of 4,900, Total Cost = $26,000 Since Total Cost = Variable Cost + Fixed Cost So: $26,000 = Fixed Costs + $3.93x (where x is the number of meals served) $26,000 = Fixed Cost + $3.93(4,900) $26,000 = Fixed Cost + $19,250 Fixed Cost = $26,000 - $19,250 = $6,750 Fixed Costs = $6,750 Since the Price of the meal is $5.77, and since at BEP, Revenue = Cost, we can calculate the BEP as follows: $5.77x = $6,750 + $3.93x $5.77x - $3.93x = $6,750 $1.84x = $6,750 x = $6,750 ÷ $1.84 x = 3,669 meals (monthly) The annual BEP = 3,669 × 12 = 44,022 meals To reach the BEP, the WHDM program needs to provide 44,022 meals during the fiscal year. If 45,000 meals are served, then Total revenue would be: 45,000 × $5.77 = $259,650 At 44,022 meals (BEP), total revenue = 44,022 × $5.77 = $254,007 Therefore if the 45,000 meals contract is completed, the profit = $259,650 - $254,007 = $5,643 If 45,000 meals are served, then Profit would be $5,643 Exercise 10.1—Answer Key Westchester Home Delivered Meals Program (Profit Analysis) Total Contracted Meals = 45,000 Break Even Point = 43,992 _______ 1,008 Revenue 1,008 Meals @ $5.77 = $5,816.16 Total Cost Per 1,008 Meals @ $3.93 Variable Costs = $3,961.44 Total Profit = $5,816.16 - $3,961.44 = $1,854.72 Exercise 10.2 New River Community Council The new BEP is 387 The new BEP is not a feasible solution because there will not be much profit. Slack capacity will exist Nicole, You did not provide the calculations for this exercise, so I do not know how you worked out this problem. Exercise 10.2 New River Community Council Newsletter Break Even Point PX = A + BX 20X = 6,000 + 3,900 + 4.50X 20X = 9,900 + 4.50X (Subtract 4.50 X From Both Sides) 15.5X = 9,900 X = 639 Maximum Capacity = 650 Break Even Point = 639 Surplus Capacity = 11 Note: There are two elements of fixed costs in this example. The salary of the Newsletter Coordinator ($6,000 per year) and the salary of the assistant ($3,900 per year) Exercise 10.3 Mountain View Senior Adult Program $4000/month allocated $65/ client $4000/month full-time salary $10/client for supplies 120 maximum clients/ nurse/ month 12*4000=$48000 allocated/year Let X=number of clients per year $4000*12=$48000/year full-time salary/nurse Break-Even Points 1 Full-Time Nurse 48000+65X=(48000+10X) 48000-48000=10X-65X -55X=0 X=0 Clients/year 2 Full-Time Nurses 48000+65X=2*48000+10X 48000-96000=10X-65X -55X=-48000 X=48000/55=873 Clients/year X=2*12*120=2880 maximum clients/year 3 Full-Time Nurses 48000+65X=144000+10X 48000-144000=10X-65X -55X=48000-144000 X=(48000-144000)/-55=1745 Clients/year X=3*12*120= 4320 maximum clients/year Part-Time Nurses 48000+65X=12*45*X 12*45*X=48000 X=48000/(12*45)=89 Clients/year The break-even points differ because the total salaries are different. With 1 full-time nurse the break-even point occurs when there are no clients. I do not think that this is not feasible because the whole amount allocated would go to the nurse and the nurse wouldn’t have to do anything for their salary. If I were the executive director I would choose the direct method with three nurses because the break-even point would allow the maximum number of clients to be served compared to the other choices. Exercise 10.3—Answer Key Mountain View Senior Adult Program Direct Service/Contract Service Delivery Decision 1. Break Even Point (With One Nurse) PX = A + BX 65X = 4000 + 4000 + 10X (4000 overhead + 4000 salary for one nurse) 65X = 8000 + 10X (Subtract 10X from Both Sides) 55X = 8000 (Divide Each Side By 55) X = 146 hours of service (BEP per month) Note: This BEP is outside the feasible range because one nurse can only provide 120 hours of service per month. Surplus Capacity (120 - 146 = None) Exercise 10.3 Mountain View Senior Adult Program Direct Service/Contract Service Delivery Decision 2. Break Even Point (With Two Nurses) PX = A + BX 65X = 4000 + 4000 + 4000 + 10X (4000 overhead + 8000 salary for two nurses) 65X = 12000 + 10X (Subtract 10X from Both Sides) 55X = 12000 (Divide Each Side By 55) X = 219 hours of service (BEP per month) Note: This BEP is within the feasible range because two nurses can provide a maximum of 240 (120 x 2) hours of service per month.

Surplus Capacity (200 - 200 = ZERO) Overall, you did well with the assignment. There was one problem/concern with the Exercise #2. The most important point here is that students will read the instructions and try to calculate the solutions. I have included the answer key/solution

Congo and Gabon won their independence from what European country? What west african country has the largest population in africa? What is nigeria's major mineral resource and largest export (same thing)?

ya but i don't have money

Sorry. The equation is y=x+6x-16.

No, that's not what I mean. I am supposed to be changing the equation y= x+6x-16 from standard form to vertex form.

i can see them..... they ARE on the current qestions page

thank you soooo much!

First, to complete this problem, you add like terms (2b and 3b)(add them together). Now you should have something like 5b-6. Now add 6 to both sides. Now you should have something like 5b=20. Next you need to divide 5 from both sides. Now you should have b=4. There you go, you should have your answer.

How do you want me to help you if there isn't even a propblem to help you with.

Supermath Electoral votes exactly adding up to Mccains 72??? You have to go over to 75? Right??

thanks! I have question though...what happened to the ^2 in the second part? Its in the second step but then where does it go?

nevermind, i figured it out

and...the time is 3.06s

You want to dress in a way that shows you are mature and care about how you look. So, I would say something dress-casual. Wear nice but comfortable shoes. You want your appearance to make people take you seriously, but not be overdone (don't draw attention to yourself by wearing something very unusual). If you're there as a student, they may want to look like a student. If you will be on camera, there are certain things camera people prefer you not wear. You might do a google search for this. I think white and stripes are things not to wear. A white shirt under a blazer or jacket would probably be OK. Good luck!

Wow, BRANDON. You have absolutly NOOOOOOOOOOOOOO LIFE WHAT SO EVER. Ha, little boy. c[:

Thank You so much. It looks so simple, and makes sense the way you wrote it out!

Thank You, how can you find a square root of a number easily?

Thank You, I saved this link.

sorry I typed the rong subject. Its suposed to be called spelling

Thank you yay now I can lern how to spell. By teacher will be happy that I can finaly spell!!! why did you giv me da first link?
