Answer:
9 or 3.8x10^-6
Step-by-step explanation:
By flipping a coin you'd look at how many times a head could appear (1/2) and multiply that by the 18 times.
Another explanation:
I'm not sure on this but would you raise 1/2 to the 18th power?
58 is a composite number because it has more than 3 factors.
Composite numbers are numbers that has 3 or more factors.
Prime numbers are numbers that only has 2 factors.
Answer:
A is the correct equation
Step-by-step explanation:
Warning: This might be rough...
First draw it out. Label the angles at the corners of the triangle 60 (definition of equilateral triangles). Now draw a line from the center of the circle to the corner, splitting the corner in half. Label this line R and a corner as 30 degrees. No to find the height of this triangle, you do rsin(30). The base of this triangle is 2rcos(30). Now find the area of this mini triangle (rsin(30)*2rcos(30)/2=r/2*rsqrt(3)/2=r^2sqrt(3)/4). Now multiply this by 3 because you have 3 mini triangles... to get...
