30lbs of onions
1 onion=6lbs per 10 kg
30 * 6=180
180/10=80
80
I hope this is correct
You would move the decimal over until there is one number left. So the answer would be 1 • 10 to the 6th power.
Answer:
Step-by-step explanation:
Lets suppose the one side be x and the other side of the rectangle be y
given area ![x*y=650ft^2](https://tex.z-dn.net/?f=x%2Ay%3D650ft%5E2)
implies x = 650/y
Cost = 2*4*x+2*3*y=8x+6y
= 8*650/y + 6y
= 5200/y + 6y
upon differentiating we get
=![-5200/y^2 + 6=0](https://tex.z-dn.net/?f=-5200%2Fy%5E2%20%20%2B%206%3D0)
= 2600/3
y=
= 43.3
x= 15
C(43.3)=
>0 hence it is a minima value
optimizing the result we get
Cost = 8*15+6*43.3 =$ 379.8
