But where is my mistake here 

The total ways of choosing any 3 movies from the 56 total is C(56,3) = 27720

And the total ways of choosing 3 of the 12 action movies is C(12,3) = 220

So

220 / 27720 = 1/126 = about .0079 = about .79%

$${{\left({{\mathtt{3}}}^{{\mathtt{3}}}\right)}}^{{\mathtt{3}}} = {\mathtt{19\,683}}$$

$${{\mathtt{3}}}^{{\mathtt{27}}} = {\mathtt{7\,625\,597\,484\,987}}$$

Because in 3^3^3,  you multiply 3*3*3=27

Then you multiply 27*27*27=19 683

3^27 is 3 times itself 27 times with no break

t cannot be solved because I CAN'T READ IT!!!!!

say / like. 8/10 or if there is a whole number put a space like 1 8/10

i dont know! benjamin franklin wrote it! XD

Unmmmm...this cannot be solved???

5*8=40    

Second answer is incorrect.  You're not subtracting 2 from 3, you're multiplying 3(1). 7+3=10

(8-2)=6

6-5=1

3-1=2

2+7=9

(9+10)=

21

3[(6)-5]+7

3[1]+7

3+7=10

It already is

If you mean a regular polygon, then the answer is no.  

If there are n sides and the exterior angle is θ, then an interior angle is 180°-θ, so we would have to have:

θ*n = 360

(180-θ)*n = 2430

so 180*n - 360 = 2430

180*n = 2790

n = 15.5

However, a regular 15-sided polygon has an interior angle sum of 2340 degrees.

Repeat the above with 2340 instead of 2430 to find n = 15

The volume of a rectangular pyramid is (1/3) x (Area of the base) x (height)

When depressed, hang in there, for the probability of getting better is much higher than the probability of getting worse -- and, when it gets better, you'll be happy that you held on ...

I think that you'll have to try that question again ...

x²xy  can be simplified to  x³y

Factor  xy - y²  to get  y(x - y)

Now, the problem is:  x³y / [ y(x - y) ]

You can now cancel the  y  in the numerator by the  y  in the denominator. After cancelling, you are left with:

x³ / (x - y)  

Which is the answer in reduced form.

However, if you meant the problem to be:  (x² - xy) / (xy - y²)

then, after factoring both the numerator and the denominator, the problem becomes:  

   [ x(x - y) ] / [ y(x - y) ]

Now, cancel the two  x - y  factors to get:  x/y

The square root of a number is a number, which when multiplied by itself, will have the original number as that answer.

Since 100 = 10 x 10, 10 is the square root of 100.

(h + 3)(h + 4)

= h(h + 4) + 3(h + 4)

= h² + 4h + 3h + 12

= h² + 7h + 12

The reciprocal of 6/5 is 5/6.

The reciprocal of any common fraction a/b is b/a.
