If the probability of spinning an A once is 1/12, then the probability of spinning an A 3 times is 3 × 1/12. 
3 × 1/12 = 3/36 
Simplify 
3/36 = 1/12
        
             
        
        
        
Answer:
A. 15
Step-by-step explanation:
To solve this you need to compare the lengths given to you in the question statement.
Because the lines originate from a single point, they're like triangles.  We can easily see a triangle AGF and a triangle ADE, right?
Both triangles are similar triangles, so we can see triangle ADE as a larger version of angle AGF.
They give you the dimension of A F and A E (through A F + F E) to establish a ratio... and they give you A G, asking for A D.
So, A F = 16, A E = 20 (16 + 4), A G = 12.
Since A D is to A G what A E is to A F, we can easily make the following cross-multiplication:

So, A D = (A G * A E)/A F
A D = (12 * 20) / 16 = 15
 
        
             
        
        
        
Answer:
u take 12 x 10=120+12=132 so the

Answer:
Formula: (x^2 -h) +(y^2 -k)=r^2
The number on the right side of the = is the radius of the circle squared.
(h,k) is the center of the circle.
