24/52 because there are 6 even number in a 13 card section
2,4,6,8,10,12
and there are four of them so you multiply 6 by 4 to get 24
since you know there are 52 cards then you will place 24 over 52
you can simplify this fraction to 6/13 depending what you want
So first factor it
1008=2*2*2*2*3*3*7
group them in similar pairs
1008=(2*2)(2*2)(3*3)*7
now remember we can do
![\sqrt{xy}= \sqrt{x} \sqrt{y}](https://tex.z-dn.net/?f=%20%5Csqrt%7Bxy%7D%3D%20%5Csqrt%7Bx%7D%20%5Csqrt%7By%7D%20%20%20)
so
![\sqrt{1008}= (\sqrt{2*2}) (\sqrt{2*2}) (\sqrt{3*3}) (\sqrt{7})](https://tex.z-dn.net/?f=%20%5Csqrt%7B1008%7D%3D%20%28%5Csqrt%7B2%2A2%7D%29%20%28%5Csqrt%7B2%2A2%7D%29%20%28%5Csqrt%7B3%2A3%7D%29%20%28%5Csqrt%7B7%7D%29%20%20%20%20%20)
=
2*2*3*
![\sqrt{7}](https://tex.z-dn.net/?f=%20%5Csqrt%7B7%7D%20)
=
12√7
the answer is B
Answer:
false
Step-by-step explanation:
Answer:
x=51
Step-by-step explanation:
There are two ways you can go about this
You can either say that the sum of interior angles in a triangle is equal to 180 so you do 180-39-90=51
Or you could use the exterior angle theorem, which means that 90=39+x, simplify that and you get that x=51
The equation of a circle:
![(x-h)^2+(y-k)^2=r^2](https://tex.z-dn.net/?f=%28x-h%29%5E2%2B%28y-k%29%5E2%3Dr%5E2)
(h,k) - the coordinates of the center
r - the radius
The center is (4,0), the length of the radius is 2√3.
