Answer:
1/10
Step-by-step explanation:
the friends eat 1/10 of the whole bar or 1/5 of half a bar
 
        
             
        
        
        
I think the answer is 6530 because ask yourself, what amount is in the hundreds section, which is 526. the rule is : if your number is past 5 hundred twenty five you round up to the nearest tenth, which is 5hundred thirty. so your answer is 6,530. I hope I explained it to be understandable...
        
                    
             
        
        
        
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
