20 oz / 36 =   5/9 oz per cookie

2(x-4)> 4x+6

2x - 8 > 4x + 6    subtract 2x from both sides and subtract 6 form both sides

-14 > 2x               dividee both sides by 2

-7 > x     or     x < -7

The number of seconds in a year is 3600 x 24 x 365  =31,536,000

So

(3.3 x 10¹²) / (31,536,000) = about 104,642 years

Well...10% of 1800m = 180m

So 20% is twice a much = 360m

So, the new route is 360m shorter  !!!

Are you trying to raise the cosine of 30° to the 4th power ???

You can put this into the onsite calculator just like this :

(cos(30))^4

Because, without math, this website wouldn't exist....and then, where would we be ????

Converting 9° C to F, we have

F = (9/5)C + 32 =

(9/5)(9) + 32 =

81/5 + 32 =

48.2° F

So, D.C. is hotter  (by a lot!!)

√333 =

√(3 * 111) =

√(3 * 37 * 3) =

√(9 * 37)

√9 * √37 =

3 √37

3 1/2x - 5 1/3x, x=2/5

So I assume you want to evaluate this expression when x = 2/5  ???

So we have

(3 + 1/2)(2/5) - (5 + 1/3)(2/5)

(7/2)(2/5) - (16/3)(2/5) =

14/10 - 32/15 =

7/5 - 32/15  =

21/15 - 32/15 =

-11/15
