Answer:
9x - 3y = 18
Step-by-step explanation:
Answer:
1/2
Step-by-step explanation:
there is a total of 12 people
6/12 people have red hair
if you simplify, it is 1/2
therefore there would be a 1/2 chance that someone with red hair would be chosen.
Outer radius: Ro = 11 m
Inner radius: Ri = 9 m
Area of the sidewalk: A = <span>π (Ro^2 - Ri^2)
A = </span><span>π ( (11 m)^2 - (9 m)^2 )
A= </span><span>π ( 121 m^2 - 81 m^2 )
A = </span><span>π ( 40 m^2 )
A= 40</span><span>π m^2
The exact area of the sidewalk is 40</span><span>π square meters
A = 40 (3.14) m^2
A = 125.6 m^2
The approcimate area of the sidewalk is 125.6 m^2</span>
82÷2=2÷2(1-8p)
41=(1-8p)
41=1-8p
41-1=1-1-8p
40=8p
40÷8=8p÷8
5=p
