Answer:

Step-by-step explanation:
In all 30-60-90 triangles, the side lengths are in ratio
, where
is the side opposite to the 30 degree angle and
is the hypotenuse, or longest side, of the triangle.
Since there are 180 degrees in a triangle, the angle on top must be 30 degrees. Therefore, its opposite side is 6 and
in the ratio
.
Thus, we have:

Answer:
5. A= pi
r=radius d=diameter
C= pi 2r/ d
A= pi 
A= 36pi
_____________________
C=pi 2(6)/12
C=12pi
____________________________________________________________
6. A=pi 
A=16pi
_____________________
C=pi 2(4)/8
C=8pi

Solution:
a. original



b. Median remains the same.
c. ![original s^{2}=(20,000)^{2}=400000000=\frac{1}{n-1}[\sum x^{2}- n\bar{x}^{2}]](https://tex.z-dn.net/?f=original%20s%5E%7B2%7D%3D%2820%2C000%29%5E%7B2%7D%3D400000000%3D%5Cfrac%7B1%7D%7Bn-1%7D%5B%5Csum%20x%5E%7B2%7D-%20n%5Cbar%7Bx%7D%5E%7B2%7D%5D)

Answer:
It is B
Step-by-step explanation:
Since its 12 trillion miles we know that the power of 10 has to be 12. We also know to move decimals forward we need a positive power. Therefore the answer is B) 
Hope it helps!!!
