Breanna sold 1,200 Of Clothes At The dress shop and earned a commission of $210. What is her commission percent?

1 answer:

8 0

If we take 1200 to be the 100%, then what is 210 off of it in percentage?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
1200&100\\
210&x
\end{array}\implies \cfrac{1200}{210}=\cfrac{100}{x}\implies x=\cfrac{210\cdot 100}{1200}$

Can you simplify this?

Brilliant_brown [7]

144 - 12g^2.

Because we don't know the value of g, there's nothing else we can do.

2. Solve for y. A 10.5 B 9 C 13.5 D 12

Vera_Pavlovna [14]

It’s A
Because if you subtract 12 from 96 you’ll get 8y=84 then divide both sides by 8 you get 21/2 simplify and get 10.5 or 10 1/2

Verify that the divergence theorem is true for the vector field f on the region

schepotkina [342]

$\mathbf f(x,y,z)=5x\,\mathbf i+xy\,\mathbf j+2xz\,\mathbf k$

$\mathrm{div}(\mathbf f)=\dfrac{\partial(5x)}{\partial x}+\dfrac{\partial(xy)}{\partial y}+\dfrac{\partial(2xz)}{\partial z}=5+x+2x=5+3x$

By the divergence theorem, the flux of $\mathbf f$ across the boundary of $E$ is given by

$\displaystyle\iint_{\mathcal S}\mathbf f\cdot\mathrm d\mathbf S=\iiint_E\mathrm{div}(\mathbf f)\,\mathrm dV$

$=\displaystyle\int_{z=0}^{z=2}\int_{y=0}^{y=2}\int_{x=0}^{x=2}(5+3x)\,\mathrm dx\,\mathrm dy\,\mathrm dz=64$
