$\frac{3}4$ of $540$ is $\frac{3\cdot540}4=405$ miles. Those will hence be traveled in $\frac{405}{45}=\boxed{9\text{ hours}}$

One week, Moussa earned $273.00 at his job when he worked for 13 hours. If he is paid the same hourly wage, how many hours would

Anarel [89]

Answer:

18 hours

Step-by-step explanation:

Hello!

Let x equal the amount of money Moussa earns per hour of work.

Let y equal the number of hours Moussa works.

Given the one week where he earned $273 for working 13 hours, we can find the amount of money earned per hour of work.

<h3>Solve</h3>

$273 = 13x$
$273/13 = x$
$21 = x$

Moussa earns $21 per hour.

We are now asked to find how many hours it will take to earn $378.

We can create an equation and solve.

<h3>Solve</h3>

$21y = 378$
$y = 378/21$
$y = 18$

Moussa needs to work 18 hours to earn $378.

Use Green's Theorem to evaluate the line integral along the given positively oriented curve. C 3y + 5e x dx + 8x + 9 cos(y2) dy

Andrei [34K]

By Green's theorem,

$\displaystyle\int_C(3y+5e^x)\,\mathrm dx+(8x+9\cos(y^2))\,\mathrm dy$

$\displaystyle=\iint_D\left(\frac{\partial(8x+9\cos(y^2))}{\partial x}-\frac{\partial(3y+5e^x)}{\partial y}\right)\,\mathrm dx\,\mathrm dy=5\iint_D\mathrm dx\,\mathrm dy$

where $D$ is the region enclosed by $C$ . Equivalently, the line integral is equal to 5 times the area of $D$ , which is

$\displaystyle5\iint_D\mathrm dx\,\mathrm dy=5\int_0^1\int_{x^2}^{\sqrt x}\mathrm dy\,\mathrm dx=5\int_0^1(\sqrt x-x^2)\,\mathrm dx=\boxed{\frac53}$
