Answer:

<em>x = 437.3 ft</em>

Step-by-step explanation:

<u>Right Triangles</u>

In right triangles, where one of its internal angles measures 90°, the trigonometric ratios are satisfied.

We have completed the figure below with the missing internal angle A that measures A = 90° - 29° = 61° because the lines marked with an arrow are parallel.

Given the internal angle A, we can relate the unknown side of length x with the known side length of 500 ft, the hypotenuse of the triangle. We use the sine ratio:

\displaystyle \sin 61^\circ=\frac{\text{opposite leg}}{\text{hypotenuse}}

\displaystyle \sin 61^\circ=\frac{x}{500}

Solving for x:

x = 500 \sin 61^\circ

Calculating:

x = 437.3 ft

What does n equal in this equation? n+4/-2=-9
myrzilka [38]

So basically you just want to isolate the variable. So you want n on a side all by itself. so first you multiply by -2 to both sides, that will leave you with the equation n+4=18, then you subtract 4 from both sides, this will give you the equation n=14. To make sure this solution is correct, you can plug it back into the equation filling 14 in for n, this equation is 14+4/-2=-9, and this solution works. Hope this helped :)

A newly constructed fish pond contains 3000 liters of water. Unfortunately the pond has been contaminated with 5 kg of a toxic c
Paraphin [41]

Answer:

\frac{dm}{dt}=-\frac{m}{30}

Step-by-step explanation:

We are given that

Volume of water in fish pond,V=3000 L

Mass of toxic  chemical=5 kg

Rate=200L/min

Removes chemical=50%

We have to find the differential equation for the time.

Let mass of toxic at any time t= m kg

Rate=Rate in-Rate out

\frac{dm}{dt}=200\times 0-\frac{m}{3000}\times 200\times \frac{50}{100}

\frac{dm}{dt}=0-\frac{m}{30}

\frac{dm}{dt}=-\frac{m}{30}
