unexpired insurance at the end of the fiscal period represents; an accrued asset, an accrued liability, an accrued expense, or a deferred expense?

what i meant was what if the sentence has an avoir past tense and a reflexive past tense? then would the sentence end up with suis and ai? and what is the order of the suis and ai? regarding je

thanks so much but is there a possible situation where both passe compose with avoir and passe compose of a reflexive verb in the same sentence?

vowel?

thanks DrBob ..I appreciate the help. I have tried many searches for the answer on the internet and felt the answer was no as I found nothing.I understand the idea of going to CO2 and H2O. I also don't think that just an O molecule can be added. Thanks again.

it is already answered

i tried that for the value of k of that material but i'm still not getting the right answer

C=(kAe)/d =[(25)(pi*.55^2)(8.85e-12)]/.0025 =8.41e-8 q1=CV =(8.41e-8)(1000) =8.41e-5 without dielectric: C=(Ae)/d =(pi*.55^2)(8.85e-12)/.0025 =3.36e-9 q2=CV =(3.36e-9) (1000) = 3.36e-6 q1-q2 =8.07e-5 C

this is not the right answer though. am i missing a step?

thanks, i finally got the right answer, i just needed to put more digits with the scientific notation. thanks bob

Does that mean divided by 12?

sorry, i don't understand Ms Sue

Ms Sue, I am not a student, just trying to find out this answer for personal reasons. Thanks for your help. I thing I multiply 3.4 time 24000 divided by 12 which is about 600 per month....right

816.00 divided by 12 I think

Quan is shopping.He can buy 2 pairs of pants and 1 shirt for $79.85 (before tax is added). He can buy 1 pair of pants and 2 shirts for $69.85.(before tax is added). To figure out how much a shirt of a pair of pants cost, you must be able to write the equations. What equations descibe this problem? a)s + p = $79.85 and s - p = $69.85 b)s + 2p = $79.85 and s + p = $69.85 c)s - p = $79.85 and s + p = $69.85 d)s + 2p = $79.85 and 2s + p = $69.85 and the answer i picked was b

which inequality is the same as -4x + 2y <= 8? a)y >= -2x + 4 b)y <= -2x + 4 c)y <= 2x + 4 d)y >= 2x + 4 i will like to know if my answer is correct or not. c

Compare and contrast China and India ca. 1400. What are some important political differences? Why do you think those differences might matter in the way world history develops in the period from 1500 to 1800?

parts a and b should be the same since its the same radial distance from equipotential line that A is on, right?

Dr Bob222 i can not see anything

thankyou Dr Bob222 and writeacher. All the best.

Diffusion, Osmosis, Active Transport, Facilitated diffusion,

if the with is 12 inches and the box takes thirty then you have 18 inches of ribbon left in the equation seeing how a box is a 3 dementinal figure it has 18 inches to share between 2 sides so you divide 18 by to and get 9 so the hight of your box would be 9

t would be 4 because 16/2x4=2 use pemdas multiply is before divide 16/8=2 right 2=2

3a+8=15-(9a-9) 3a+8=15-1(9a-9) 3a+8=15-9a+9 +3a +3a 12a+8=15 -8 -8 12a=7 /12 /12 a=.5833 repeating

i don't understand 3/6 dose not equal 1/3 its 1/2

i think your asking what the odds are that you will pick a odd number if picked from 36 cards numbered 1-36 if so 1 is pime 2 is prime 3 is prim 5 is prime 7 is prime 11 is prime 13 is prime 17 is prime 19 is prime 23 is prime 29 is prime 31 is prime and that's it so that means out of the 36 numbers you have 12 are prim so the probubility of picking a prim number out of the 36 is 1/3 because you reduse it

its hard to exsplane without signs google long division

a vowel is a,e,i,o,u so count how many letters there are in the word then count how many a,e,i,o,u, letters there there are then put the number of vowels there are over the amount of letters there are in the word then simplifiy

where do you get x3 from? do you mean 3x?

yes

a ratio is 60:120 one way i remember this is by saying it 60 TO 120 when you say a ratio you say to and when you use a fraction you say by.

ok so your parallegram looks like this 5 l----\ 4l-----\ 7 so you know that the bottom line has 2 more meters then the top so what you do is you cut that off from the shape and think of it as a 5x4 rectangle 5 ______ [\ 4 [ ] 4[ \ [ ] [__\ ------ 2 4x5=20 4x2=8 8/2=4 find the answer to that equation then take your leftover triangle whitch is 2x4 because its the leftover 2 from the bottom line then multiply 2x4 then divide by 2 because its a tryangle then add up both equations and you have your answer 20+4=24

sorry that didint work well

yes

or 2/5

just do the problum backwards if you have the answer to the square root what you do is square that number ^5x=5 5x5= 25 ^25=5 so now that you have the number being square rooted all you have to do is find our the answer to this equation 5x?=25

you have to put it into a vertex form y=a(x-h)^2 +k y=x+4(because of sign ||)+8 now you have to get ^2 y=a(.5x-2)^2+8 y=1(.5x-2)^2+8 now k shifts up or down IE y axis h shifts left or right IE x axis but a +h=-h and a -h=+h so your vertex would be (2,8) because h is -2 and k is 8

if a 1 block means ones 10 block means tens and 100 block means 100s then the number would be 842 because 8 is 2 times as much as 4 and 4 is 2 times as much as 2

yeah 421 too

this equation is writing as ax^2+bx+c you need to find x. the equation for x is x=b/2a plug it in b=24 a=4 x=24/2x4=24/8=3 if x = 3 plug it in to your equation 4(3)^2+24(3)+39 4x9+72+39 36+72+39=147 so the vertex is (3,147) because a is 24 its positive meaning it opens up makeing the minimum value the vertex(3,147)

thanks just new way of putting it thansk

Hello drwls. Please can you explain how you get 72sqrt2+c. Surely, if it is 50.911=50.911+c, if one subtracts either side c=0? Am I missing something?Thank you for your help.

Ms, Sue, you don't have to be so rude to let me know I misspelled a word. I will make a fix that. Thank you for the heads up

Lew flew to Venezuela and saw angel falls where the water drops 3,212 feet. how much higher this waterfall than the empire state building,which is 1,250 feet high?

Airplane flight recorders must be able to survive catastrophic crashes. Therefore, they are typically encased in crash-resistant steel or titanium boxes that are subjected to rigorous testing. One of the tests is an impact shock test, in which the box must survive being thrown at high speeds against a barrier. A 41 kg box is thrown at a speed of 220 m/s and is brought to a halt in a collision that lasts for a time of 6.5 ms. What is the magnitude of the average net force that acts on the box during the collision? Round answer to nearest 100,000's place i.e. 123456789 would therefore be 123500000

true

the force you would need to accelerate an object with high mass quickly is the biggest one.

450 Surface Area of a Box: 2lw + 2lh + 2wh

V=pi*r*h V=pi*6*12 V=72 pi or roughly 226 ft^3

it comes out as 450 for me in the calculator, 300+90+60

Oh, the reactant involved is KOH. I forgot to mention that.

Get the slope: y2-y1/x2-x1 m= (5-4)/(3-4) m= -1 formula y-y1=m(x-x1) pick a set of points. y-4=m(x-4) y-4=(-1)(x-4) y-4=-x+4 y=-x+8 There is the equation.

Slope of parallel lines are the same. m = -9/2 here so the new line will have a slope of m= -9/2 as well. Through the points (-2,5) y-y1=m(x-x1) y-5=(-9/2)(x--2) y-5=(-9/2)(x+2) y-5=(-9/2)x+(-9) y=(-9/2)x-4.

ahh yes I multiplied by 10^-3 instead lol thank you!

first you need to write out the balanced reaction equation of LiOH reacting with CO2. So... 2LiOH + CO2--->Li2CO3 + H2O You start with 920 g CO2 and use this equation to convert to moles CO2 and then to moles LiOH. There are 2 moles LiOH for every 1 mole of CO2. And finally convert to grams of LiOH.

Thanks sir! :)

According to the world wide web, there are 3. 1)Non-nucleoside reverse transcriptase inhibitors 2)reverse transcriptase inhibitors and 3)protease inhibitors. I would say the simple answer is generally "Inhibitors"

unlessss.... I just solve for mass and the 20 kiloton is just extra useless information meant to throw people off and do this: e=mc^2 m = E/c^2 m = 8*10^13 J / (3.0*10^8 m/s)^2 m= 8.89 * 10 ^-4 kg hmm

thank you! How would I know not to use the mass of 20 kilotons though? I wish they didn't put that in the question it really throws you off haha

Mg--->MgO .248 g Mg x (1 mol Mg/MM Mg) x (1 mol MgO/1 mol Mg) x (MM MgO/1 mol MgO) MM are molar masses.

how much yellow paint is needed to mix with one cup of red paint

use the formula q = m*c*deltaT

15.0%

Rules for addition and sig figs are that you go by the decimal place. 2.1 has 1 decimal place. So the answer has to have 1 decimal place as well. 1.3*10^4.

I would go with B. It's the only choice that states the product is greater than 4.

wait just kidding, its already noted that Y is the product, so it would be C, my bad.
