The reciprocal of a/b is b/a.

Since 5 = 5/1, its reciprocal is 1/5.

Each side is a square of the area of one side is 6 cm x 6 cm  =  36 cm².

There are 6 sides, so the total surface are is 6 x 36 cm²  =  216 cm².

1 mm = 0.1 cm.

To find the volume, multiply the total area by the thickness:  216 cm² x 0.1 cm  =  21.6 cm³.

(This won't include any amount that is needed for "wrap-around".)

Step #1: Add up all the variables (x) 

5x+2x=7x, 7x-9=40

Step #2: Add 9 to 40=49, 7x=49

Step #3: Divide both sides by 7, x=7

Answer: x=7

If sin(A) = 12/13, then the value of the side opposite angle A is 12 and the value of the hypotenuse is 13.

To find the third side (the side adjacent to angle A) can be found by using the Pythagorean Theorem:

  c²  =  a² + b²   --->    13²  =  12² + b²  --->   169  =  144 + b²   --->   b²  =  25   --->   b = 5   

Since the adjacent side has a value of 5 and the hypotenuse has a value of 13,

cos(A)  =  adj/hyp  =  5/13.

Substitute x = 2y + 6 into the equation:  x² + y²  =  36

--->   (2y + 6)² + y²  =  36

Now simplify, factor, and finish ...

Ummm.....Here?

There's going to be one person who says.

My name is Jeff.

You say that v = 80% if the speed of light in the vacuum, so v = 0.80 x 299 792 458 m/s.

You know T, v, and c so place them into the equation ... 

Hahaha! Don't judge me by my age. Joking, I think this will work out <Genius than world.

:)

5 points for everyone!

Thanks Melody, but most of the questions have already been answered.

Honestly, I don't know what wrong...I'm just having on of them 'Emo' moments.When you feel sad for no reason.

Hi Anonymous, the thanks for the pic.?

Rosales, thanks that put a grin on my face, but it didn't last long,goodnight to you.

And Finnaly (pants) MathAnswerer thanks but I couldn't find anything most of them just make you laugh.

PS: Loads of user on!!!!

Since the 3 is attached to the x-term by multiplication ( 3x = 3·x ) and equations are solved by doing the opposite, DIVIDE both sides by 3!

Probability is the likelyhood that an event will occur; like one out of six for a die, or one out of two on a coin. So like maybe do a dice or coin game!😀

My name is Jack Overland Frost. How do I know that? The Moon told me so, and that's all he ever told me.

Well. I can't have what you are suggesting because i can't have beef.  But thank you anyways.

Umm..... Food. Like, Gluten free spaghetti with beef to make up the flavor. :) Hope i helped.

???????? IDK Ask someone who is smart.

im sorry your feeling deppressed and lonley, i also share that trait every day and have grown used to it. best wishes to overcoming it! 

I don't see a sigma symbol on the calculator.

If you mean ∑ from the insert menu, then yes, but that's for display only, not for calculating.  If you mean in LaTeX, then yes, but, again, that's display only.

.

32 - (-22) 

32 + 22 

54

32-(-22)?=54 2 negatives make a positive. Funn yhow this use to trip me up

judging by that picture your feeling very.....Grudge....Like?

Answer to part 1.

E(x+y) = E(x) + E(y) = 1/2 + 1/2 = 1

.

Sorry Melody, will do!
