A full circle is 360 deg.
A full circle is 2 pi radians.
That gives us a conversion equation:
2 pi radians = 360 deg
which can be reduced to
pi radians = 180 deg
Divide both sides by pi radians to get
1 = (180 deg)(pi radians)
Now we can convert:
11 pi/4 radians * (180 deg)/(pi radians) = 11/4 * 180 deg = 495 deg
Answer: 240 boys and 160 girls
Step-by-step explanation: 3 + 2 = 5
400/5 = 80

Answer:
1) y=18
2)y=-0.18
Step-by-step explanation:
1) y-15=3. Add 15 on both sides.
y=18
2)-2.1+5y=-3. Add 2.1 on both sides
5y=-0.9. Divide 5 on both sides
y=-0.18
