Let's look at this again, rosala........

(2 / 3)  x 3  =

(2 /3) x (3 / 1)

6 / 3   =

2

.....oops.

x,y and z could be anything!

Answer:9901481

4 + 4/4  + 4/4  =   

4 + 1 + 1  =

6

{There are surely other answers......!!!!   }     {  4! / 4  is another possibility, for instance }

log5x+log(x-1)= 2         Note.......   2 = log 100

log (5x * (x -1) )  =  log 100        and we can now just  ignore the logs and solve directly

5x ( x - 1)   = 100    simplify

5x^2 - 5x   = 100   

5x^2  - 5x  - 100  = 0      divide through by 5

x^2 - x - 20   = 0       factor

(x - 5) ( x + 4)  = 0        and setting both factors to 0 we have that  x = 5 or x  = -4

We must reject -4   because it makes the original logs negative......and that's undefined.....thus......

x = 5  is the solution

r = √[ (-12)² + (-15)² ]     =  √289   = 17

sin Θ = -15 / 17            csc Θ is the reciprocal

cos Θ = -12 / 17            sec Θ  is the reciprocal

tan Θ  = -15 / -12  =   15 / 12      cot Θ  is the reciprocal

@DarkBlaze:/   The question asks for the length of the arc of the 250^o  sector, not the area of it.

8 + 9/84 =

8 + 3/28    =  227/3

A circle has a radius of 32cm. To the nearest hundredth, what is the length of the arc that has a measure of 250 degrees(?)

2(32*pi) = 201.06

201.06/360=0.5585

0.5585*250=139.63

3|2x-5|>21     divide both sides by 3

l 2x - 5 l > 7    and we can write

-7 > 2x - 5 > 7      add 5 to both sides

-2  > 2x > 12         divide both sides by 2

-1 > x > 6

So.....the solution set  is  ( -∞, -1) U  (6, ∞ )

A=pi*r^2*(x/360)

x is the degree measure of the arc, r is radius.

Plug in the values.

She must sorry he, 'cause in the bottom he's a good person... It is true that he had commeted so much mistakes in his live ( family, drugs, alcohol... ), but he try to get better! ( ABOUT EMINEM )

Wiz Khalifa and Charlie Purth are the best singers for a amazing film like Fast and Furious.
