There is an excellent discussion of this on Wikipedia:  https://en.wikipedia.org/wiki/P_versus_NP_problem

Your own formula:

(acceleration = change in velocity/time interval)

4m/s^2 =change in velocity/15s, so

Velocity =4m/s^2 x 15s =60 m/s

In the middle of the far-left-hand row is  (cos^-1); this is the key to use to find the inverse cosine.

I think that it means that in the season of 180 games, the red team has the probability of winning each game of 0.55, so the expected number of games that the red teams wins is  0.55 x 180  =  99 games.

Since the blue team has a probability of 0.60, the expected number of games that the blue teams wins is  0.60 x 180  =  108.

So, the blue team is expected to win  108 - 99  =  9  more games.

Since the percentages don't refer to the same team, the percentages do not have to add to 100.

You would just use the division function; since a fraction is top divided by bottom. The calculator will evaluate as a decimal, so if you type 3/4, it will display .75

Thanks!

Oh ok thanks!!

Don't call others that, especially without proper spelling, punctuation, or capitalization.

YES !!!! Just divide B/A =84.82 /9.42 =~9. So the ratio of B to A is 9:1, Or the reverse 1:9 is the ratio of A to B.

The volume of a cylinder is  pi*r^2*h

Both cyliders have the pi and they both have the height of 3 so...

Only the r is different in the 2 cylinders so the ratio of the volumes is just    \(1^2:3^2 \) 

whichi is just   1:9

12 + 8 = 20.

So it's 1:9?

Volume of A =Pi x r^2 x h

                       =3.141592 x 1^2 x 3

                       =~9.42 m^2 Volume of cylinder A

Volume of B =3.141592 x 3^2 x 3

                       =~84.82 m^2 Volume of cylinder B

Ratio of A to B =9.42 / 84.82 =0.111. Or, a ratio of ~ 1:9

What about triangle ABC?

GOSH never mind... i had completely missed an image showing extra information.

13=x(-4)

How am I supposed to solve that ?

\(13=x(-4) \)

Do you mean

\(1) \qquad 13=x\times (-4)\\ 2) \qquad 13=x-4\\ or\\ 3) \qquad 13=x^{ -4}\\\)

Answer my question and then I can answer yours :)

What i have managed to push it down to, that i believe is correct is 

zc.pc = 5.pw + 7.po + (zc-20).pm

I am not sure either MG

I think we need more info, there must be more than just the 2 teams in the competition.  There is 180 games but I do not know how many ofthem the blue or red team actually plays. 

I am probably suppose to assume things but i am not sure what that is. 

Sorry i cannot be of more help :(

Please. I don't know what to do with this.
