Answer:
0.16 π
Step-by-step explanation:
Using the area formula pi*r^2 we can find the area of the circle, plugging in the numbers gets us pi*(0.4)^2 = 0.16 π
Answer:
D. 2 to 1
Step-by-step explanation:
I calculated it logically
There can be 6 teams because 2 is the lowest number that can go into both 12 and 18. (12/2) = 6...and I know (18/2 = 9) but there wouldn't be enough boys to make 9 teams
there will be 6 teams each containing (12/6) = 2 boys and (18/6) = 3 girls
Y=-2/3 x-2
y=-2x+2
We solved this equations system by equalization method.
-2/3 x -2=-2x+2
Least common multiple: 3
-2x-6=-6x+6
-2x+6x=6+6
4x=12
x=12/4=3
y=-2x+2
y=-2(3)+2=-6+2=-4
Solution: x=3; y=-4
To chek:
y=(-2/3)3-2=-4
y=-2(3)+2=-6+2=-4
