in 1920 the republicans did something they hadn't done in a very long time. What was it?

Each number adds a digit: Example 6,38,932,1087,12437,123456,1234567,12345678,123456789, ect... The pattern is not the number itself, but how many numbers in each... Good Luck!

thanks!!

Sixty-five hundredTHs is 0.65 (0.065 would be sixty-five thousandths).

[H30+] = 10^-(pH goes here) A log is an exponent. Since pH is a negative log, it's an exponent with a negative sign on it (with an implied base of 10).

what is the formula or how did you get that answer?

that explains it better thanks Reiny

I need to invest on that calculator thanks Kerri

from the FBDs wouldnt u get for M: Fy = N-WM=Ma Fx=T=Ma for m: Fy= T-Wm=ma Fx= T-W=ma then solve for a in M of Fx and sub a into m of Fx to get T?

Sorry i see the mistake I made for m the acceleration would be negative since its moving down

i don't know..i just need help.

@Malogis I agree 100% :P

Given: They collected 49 + 72 + 108 + 121 = 350 lbs of cans. So, the KNOWN part of the question is, “These folks collected 350 lbs of cans.” Answer: 10 I say the answer, 10, is really, “10 cents per pound.” Therefore, the UNKNOWN part of the question is, “They were paid $ X for the 350 lbs of cans. How many cents per pound were they paid?” (The answer, of course, is already given.) The task is to figure out what the $X they were paid in total, so you can plug that into the question. You find that by multiplying the 350 lbs x the $0.10 per pound = $35.00. So then, the final complete question and answer is this: Q: The kids collected 49 + 72 + 108 + 121 pounds of cans. They were paid $35 for the cans. How much did they receive per pound? A: 10 cents per pound

KE=1/2mXv KE=1/2(5kgX10m/s^2) KE=1/2(5kgX100m/s^2) KE=1/2(500kgXm/s^2) KE=250kgXm/s^2=250J

I got 2.67 m/s from your equation. But the correct answer is supposed to be 3.6 m/s.

Also, for part C, do I do KE final minus KE initial? So 1/2(5.06)(75^2) - 1/2(0.06)(225^2) ?

You're right. My mistake! Thank you...

The above answer in incorrect. Eventhough there was monopolies which were created by the govt. through loans, as all monopolies are created, thiis time period was an excellent one for the u.s.a Trists developed through innovation using the bessemer proccess and vertical and horizontal integration. The effect on the economy was that it produced a time period in which the well being of the common man elevated to the greatest in history. It also resulted in labor unions to defend the rights of the individual.

Try this way: Perimeter = 2x+2 therefore P = 2x + 2/x^2 d(perimeter)/dx = (2x^3-4)/x^3 solving for x = 2^(1/3) therefor y was given as y = x^-2 plug x into y to solve for y. y = 2^(-2/3) or y = (1/4)^(1/3) check the answer it should be 3.78

@Mia, for someone who is a story teller, you sure do know how to "spell" hahaha!

Well you see Bob, first you would use the commutative property and change it to some thing like this: (7.8* 800) *10 to the 12th= (7.8*80,000) *10 to the 10th.

google it

.4 The probability of two independent events occurring in succession is the product of the two events' independent probabilities. .22 = that product. Because we know the probability of the first being red and the second not being red (.33), we know the probability of the first light being red: .22 + .33. That comprises all the possible ways the first light can be red. From there, just divide .22 by .55 in order to get .4. Tough problem because they phrased it ambiguously.

Would it be possible to give me a more step by step? Im lost

Oh, thank you. The 5∫3 just mean the upper and lower limts, I didn't know how else to write it

Thanks. Would that just be answer, or would I need to multiply the integral by 2?

Oh wait, shouldnt the limits be [0,-1] not [0,1]? Also is the answer then pi/2?

The answer is D. The volume of the rectangle = 180 x 1/3 x 1/3 x 1/3 = 180/27=6 + 18/27. Unit cube = 1 x 1 x 1

9. .27/.03=27/3. You can multiply the numerator and denominator by 100 to absolve decimals.

V=area of base x height. area of base = pi R^2. 1 ml = 1 cm^3. convert all numbers to same units and divide through to get H. 1,408,000,000 / (3.14x400x400)=2802.5 cm = 28.03 M.

that is difficult

Well, what's the other temperature? You need two numbers to compare them. If the temperature is 2 degrees less than the other, then it would be: 70° F>68° F Using 70 as the first number.

@Ms. Sue How is she being disrespectful? She's just asking. @Reed She is not giving the answer, that is what she thinks. Also, you just gave her the answer anyway, so it really doesn't matter. @Kate @lisa Based on Reed's answer, it's arpeggio.

The Housatonic originates in the Berkshire mountains in western Massachusetts. The city of Pittsfield, Massachusetts is where the East Branch, West Branch and Southwest Branches combine into a single "mainstem" river. By base level, you mean lowest level? That would be 0' (Sea Level) at the mouth, where it empties into Long Island Sound. More info can be found at hvatoday-dot-org

Anon, Insertname, and Failing are all right, I just took the quiz.

Steve, You are right that A will never reach (0,0,1000). It was a typo, I meant to say (0,100,1000). But the question is not to find out how fast B needs to go. Ive already said its going the exact same speed as A. 20m/sec. Im trying to find out what should the starting point for B be such that if A and B are travelling 20m/sec, B will reach (0,0,1000) when A reaches (0,100,1000).

@Behind you. Not what she meant. She was asking what the right answers are, because Lol said they were wrong.

These are all things you can google. You won't get help here.

Bro. The answer is obviously 6

I know this is several years late but thanks for the answer! It helped a lot.

I did it and found Ei = 7500N then i solved in Ef = mv^2/2 + mgh and solved for h, which gave me 7500N - 7.5v^2/1.47 then i solved everything but it gives me 0, idk what im doing wrong

Thanks but unfortunately the automated reply , amazing though it is has missed the target. It would seem that it failed to comprehend the tangent part of the question. I have no idea how to calculate this myself but was expecting the answer to be several hundreds of miles. Hopefully someone will be along soon to sort me out. Thanks Rob

Many thanks Rob
