Answer:
BD and BE are tangents to the circle
Step-by-step explanation:
Given
See attachment
Required
What does BD and BE represent?
From the attachment, we have:
The measure of angles between a tangent and the radius of a circle is always 
So, because and AD is a radius, then BD is a tangent to circle.
Similarly,; and AE being a radius implies that BE is a tangent to circle.
Answer:
Step-by-step explanation:
The<em> theoretical </em>frequency would be 1/4, and if spun 60 times, 15/60.
The <em>relative</em> frequency is how many times it <em>actually</em> landed on each color.
So green is 6/60
Blue is 24/60
Yellow is 9/60
Red is 21/60
I don't know if they want these in their simplest form (sometimes the test says one way or the other), but here they are, reduced:
Green: 1/10
Blue: 4/10
Yellow: 3/20
Red: 7/20

1. Find the Greatest Common Factor (GCF)
GCF = 3
2. Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF)
3(9/3 + 3p/3)
3. Simplify each term in parentheses
3(3 + p)
0.2x+10-6 = 12x +80
0.2x-12x = 80-10+6
-11.8x = 76
x = -6.44 (around)
