Distribute 6 thru the parenthesis=
198 pie plus 6 pie
Factor out the perfect square=
Pie 3 to the second power times 22 plus 7 pie 6
Calculate the square root =
3 pie 22 plus 7 pie 6
Which equals to 31.2177
-1 is the answer or your answer is gonna be false
Is there more context to the question?
We know that
[length of a circumference]=2*pi*r
diameter=10 cm
r=10/2-----> 5 cm
[length of a circumference]=2*pi*5-----> 10*pi cm
if 360° (full circle) has a length of -----------> 10*pi cm
X°---------------------------> pi cm
X=pi*360/10*pi------> 36°
the answer is 36°
Total no. of buttons = 300 + 700 + 1000
+ 500 = 2500
Possibility for a person to pick a pink button = 300/2500 = (3/25)%
Amount of pink buttons she can expect her friends to pick = 50(3/25) = 6
She can expect to make 6 pink barrettes.
