A circle is 1 revolution or 360 degrees. So, the probability that a dart <span>will land in the unshaded region is
</span>

The answer is
67%.
Answer:
10
Step-by-step explanation:
because there are 20 girls and 10 boys = 30
Distance is calculated by the square root of (x2-x1)^2 + (y2-y1)^2
We simply substitute the values into this formula
Square root of (3--5)^2 + (0-1)^2
Which is 8
<h3>Explanation:</h3>
GCF: the greatest common factor of numerator and denominator is a factor that can be removed to reduce the fraction.
<em>Example</em>
The numerator and denominator of 6/8 have GCF of 2:
6/8 = (2·3)/(2·4)
The fraction can be reduced by canceling those factors.
(2·3)/(2·4) = (2/2)·(3/4) = 1·(3/4) = 3/4
___
LCM: the least common multiple of the denominators is suitable as a common denominator. Addition and subtraction are easily performed on the numerators when the denominator is common.
<em>Example</em>
The fractions 2/3 and 1/5 can be added using a common denominator of LCM(3, 5) = 15.
2/3 + 1/5 = 10/15 + 3/15 = (10+3)/15 = 13/15
