The numerator represents the chance of landing on the colour, and the denominator represents the number of spots you could land on. You have a 2 out of 7 chance to land on blue because there are 2 blue spots. This means that for every 2 times out of 7 spins you would land on blue.

The answer to this is C I think, I'm usually always correct so trust me k?
Central angle of a regular polygon:
Ф = 360° : n.
If n=12: Ф = 360° : 12 = 30°
At the angle of rotation Ф = 30° the image of the polygon will coincide with the preimage.
Hey there!
To start, first let's assign a variable to each person:
A to represent the miles biked by Albert
B to represent the miles biked by Bob
Now, let's set up a system of equations:
A=3B
A + B = 72
Next, use substitution (plug 3B in for A in the second equation since A is equal to 3B):
3B + B = 72
Then, simplify and solve:
3B + B = 72
(combine like terms)
4B = 72
(divide both sides by 4)
B=18
Now that you know the amount that Bob biked, you can plug his miles into the equation for Albert: A=3B
B=18
A=3(18)
A= 54
Your final answer would be that Albert biked 54 miles.
Hope this helps!
