Answer:

-\frac{3}{4}  meters

Step-by-step explanation:

From the answer choices, we basically need to find which of them is between   -\frac{1}{2}  and  -1\frac{2}{3}

<em>Converting all of them to decimals would make it really easier:</em>

<em />

<em>So we need to find number between -0.5  and -1.67</em>

<em />

<em>Answer choice A is -2.33</em>

<em>Answer choice B is  -0.75</em>

<em>Answer choice C is  -0.25</em>

<em>Answer chioce D is  -1.83</em>

<em />

<em>So which number, from the choices, is between -0.5 & -1.67?</em>

Clearly, it is -0.75, or,  -\frac{3}{4}  meters

ivann1987 [24]

Answer:

$12

Step-by-step explanation:

 12 because first you need to divided 45 by 5 to get 9 which is the cost of each ticket with the price off of each next you need to add 3 to nine because each ticket was 3 dollar off so the answer would be 12

Your swimming pool containing 60,000 gal of water has been contaminated by 6 kg of a nontoxic dye that leaves a swimmer's skin a
Paul [167]

[a] Dye is removed from the pool at a rate of

(250 gal/min) * (<em>q</em>/60,000 g/gal) = -<em>q</em>/240 g/gal

where <em>q</em> denotes the amount of dye in the pool at time <em>t</em>. Clean water is pumped back into the pool, so no dye is being re-added.

So the net rate of change of the amount of dye in the pool is given by the differential equation,

\dfrac{\mathrm dq}{\mathrm dt}=-\dfrac{q(t)}{240}

with the intial value, <em>q</em>(0) = 6000 g (or 6 kg).

[b] The ODE above is separable as

\dfrac{\mathrm dq}q=-\dfrac{\mathrm dt}{240}

Integrate both sides to get

\ln|q|=-\dfrac t{240}+C

e^{\ln|q|}=e^{-t/240+C}

\implies q(t)=e^{-t/240+C}=e^{-t/240}e^C=Ce^{-t/240}

Now plug in the initial condition:

6000=Ce^0\implies C=6000

so the particular solution to the IVP is

q(t)=6000e^{-t/240}

[c] The acceptable concentration of the dy is 0.03 g/gal, which in a pool containing 60,000 gal of water corresponds to

(0.03 g/gal) * (60,000 gal) = 1800 g = 1.8 kg

of dye. Find the time <em>t</em> when this occurs:

1800=6000e^{-t/240}\implies0.3=e^{-t/240}

\implies\ln0.3=-\dfrac t{240}

\implies t=-240\ln0.3\approx288.953

so the amount of dye in the pool is within the acceptable tolerance after about 289 min have passes, or about 4.82 hrs. So no, the filtration system is not up to the task.
