Answer:
0.4
Step-by-step explanation:
33+72+55+20=180
probability of choosing of choosing a maths teacher=72/180
=0.4
Circumference = 2 * pi * r, where r is the radius
For this circle, the circumference is 11pi, so 11pi=2*pi*radius. Divide both sides by 2pi and you get r is = to 5.5 inches.
Area of a circle is pi*r^2. Since we just saw that r = 5.5 inches, the circle has an area of 5.5 inches * 5.5 inches * pi or 30.25 pi inches squared.
C. -5y -4 = -(x+3)^2 -1/2
Hope I am right.
A. Associative property, because even tho it's grouped with different numbers it still gets the same number/total
