Holy s.hit you're r.etarded

Find the sum of the multiples of 19 or 5 under 775.

Well, the easiest way to do it is as follows:

775 / 19 =40.7894....... Just drop the fraction and keep 40. That means there are 40 multiples of 19 up to 775.

Now, you can use an Arithmetic Progression to add them up:

Sum =n/2[2a + (n - 1)d] =40/2[2*19 + (40 - 1)*19] =20[38 + 741] =15,580 - which is the total of all multiples of 19 up to 775.

Now, do exactly the same thing with 5 =775 / 5 =155. This is how many multiples of 5 you have up to 775.

Use the same formula as above to add them all up. If you do it right, you should get a total of =60,450. Now, try to see if you get the same number. Good luck.

Thank you!

I'd guess the second choice:

"The show was genuinely and extremely funny"

7/14 = 0.5

-50,000,000

Yeah I'm nothing

X is equal to 6

if you have a total of 779 and 576 is completed what is 90%.

I'm not sure if I understand your question. But, if you have completed 576 out of 779, that means you have completed: 576 / 779 =0.7394 x 100 =73.94%

If you want to complete 90%, then:

90% x 779 = 0.90 x 779 =~701, which is about 90% of 779.

I hope that answers your question.

While I can't give an exact definition, linear equations, if graphed, will be a single straight line.

ie  76+9x=2

Because Somethings are and somethings ARENT

You can type fractions into the main calculator like this:

numerator / denominator

So three fourths would be

3 / 4

Make sure your problem displays right at the top, if it doesn't display right, you might need to add parenthesees around the numerator or denominator or around the whole fraction.

While I frankly don't care you will post mostly off topic, I can say I am quite livid that both "I'm"s don't have apostrophes. This may be a math forum, but that does not mean you get to let your English slip.

You can trace a circle around a lot of things.

You could trace around a can of coke, a burger king cup, a regular cup, a bottle of water, a water bottle cap, a roll of duct tape (inner or outer ring) a paper towel/toilet paper tube, or a mood ring...

And, if you have a compass, you can make circles with that.

HMMMMMMM !!  

I just looked at part e some more...

The formula for the "perimeter" of a circle is

c = 2 * r * pi

The formula for the  perimeter  of a n-gon is

p = 2 * r * sin(\(\frac{180^{\circ}}{n}\)) * n

With really big values of   n   ,     sin( \( \frac{180^{\circ}}{n} \) ) * n     must be close to pi !!

So...I tried that

with n = 1,000:            sin( \(\frac{180^{\circ}}{1000}\) ) * 1000   ≈   3.141587

and

with n = 50,000:          sin(\(\frac{180^{\circ}}{50,000}\) ) * 50,000   ≈   3.14159265

I thought that the limit as n approaches infinity would make it exactly pi,

no sorry

Is it 26?

The question is not why, but what?
