Answer:
see below
Step-by-step explanation:
First we need to find the radius
r =d/2 = 15.8/2 = 7.9 cm
The area of a circle is given by
A = pi r^2
= pi ( 7.9) ^2
=62.41 pi
Using 3.14 for pi
195.9674
To the nearest hundredth
195.97
Using the pi button
196.0667975
To the nearest hundredth
196.07
Answer:
x=35
Step-by-step explanation:
2x+15+2x-10+x=180
combine factors
5x+5=180
-5 from both sides
5x=175
divide 175/5x
x=35
Answer:
C ($19.25)
Step-by-step explanation:
First, find how much 1 carton costs, which is $8.75 divided by 5, which is $1.75. So, to find how much 11 cartons cost, we just multiply by 11 to get [tex]\boxed{\$19.25}[\tex]
Answer:
70%
Step-by-step explananation:
sorry for the previous answer I was thinking u meant something else
We have
<span>Va(airplane)=150
East</span>
Vw(wind)=7.1
South East
<span>
</span><span>resulting vector R</span>
airplane
Vax=150 Vay=0 it only has component x
WindVwx=7.1*cos45=5.02
Vwy=7.1*sin45=-5.02
is negative because is South direction
|R|=(Rx^2+Ry^2) ^0.5
Rx=150+5.02=155.02
Ry=0-5.02=-5.02
<span>|R|=155.10
miles/hour South East</span>
Determine angle θ
Rx=R*cos(θ)
<span>Cos(θ)=Rx/R</span>
<span>Cos(θ)=155.02/155.10=0.9995</span>
θ =arc cos Rx/R
θ =1.8119 º
Rx represents the component in the East direction of the resultant force. Your contribution is given by both, the force of the plane and the wind. The contribution of the wind makes the airplane's speed greater
Ry represents the component in the South direction of the resulting force
Its contribution is exclusive of the wind since the airplane has no component
in this direction
|R| the force resulting from the combined action of the force of the plane and the force of the wind
θ represents the angle that forms the resultant force with respect to the x axis or east direction
