11 is 40% of
27.5Change the percentage to a decimal by dividing it over 100:
![\frac{40}{100} = 0.4](https://tex.z-dn.net/?f=%20%5Cfrac%7B40%7D%7B100%7D%20%3D%200.4)
Divide 11 over 0.4:
Answer:
![-1\°](https://tex.z-dn.net/?f=-1%5C%C2%B0)
Step-by-step explanation:
Let
x -----> the wind speed in mi/h
y ----> the wind chill in °F
we have
![y=-0.36x+12.6](https://tex.z-dn.net/?f=y%3D-0.36x%2B12.6)
so
For x=38 mi/h
substitute in the linear equation and solve for y
![y=-0.36(38)+12.6=-1.08\°](https://tex.z-dn.net/?f=y%3D-0.36%2838%29%2B12.6%3D-1.08%5C%C2%B0)
Round to the nearest degree
![-1.08=-1\°](https://tex.z-dn.net/?f=-1.08%3D-1%5C%C2%B0)
Answer:
d =13 cm
r = 6.5 cm
Step-by-step explanation:
The diameter is the distance across the circle, going through the center
d = 13 cm
The radius is 1/2 of the diameter
r = d/2 = 13/2 = 6.5 cm
Answer:
8
Step-by-step explanation:
![\frac{23}{2} = 11.5](https://tex.z-dn.net/?f=%20%5Cfrac%7B23%7D%7B2%7D%20%20%3D%2011.5)
