I was wondering what is 9/2 divided by 1/2

liubo4ka [24]

Answer:

$\frac{18}{2}$ or 9

Step-by-step explanation:

1. Set up the problem: $\frac{9}{2}$ ÷ $\frac{1}{2}$

2. Replace the division sign with a multiplication sign: $\frac{9}{2}$ × $\frac{1}{2}$

3. Find the reciprocal by swapping the numerator and denominator on the second fraction: $\frac{9}{2}$ × $\frac{2}{1}$

4. Multiply fractions: $\frac{9}{2}$ × $\frac{2}{1}$ = $\frac{18}{2}$ or 9

Which expression is equivalent to:1/m6

Valentin [98]

Answer:

A

Step-by-step explanation:

6 is a power. So both C and D are wrong because 6 is being treated as an ordinary integer.

So the answer must be either A or B.

B is not correct because to move an expression from the denominator to the numerator changes the sign in the base (which is m in this question).

A is correct. the power is changed from 6 in the denominator to -6 in the numerator. m is shifted to the numerator as well.

A tank with a capacity of 500 gal originally contains 200 gal of water with 100 lb of salt in solution. Water containing 1 lb of

saw5 [17]

Let A(t) denote the amount of salt in the tank at time t.

Salt flows in at a rate of

(1 lb/gal) * (3 gal/min) = 3 lb/min

and flows out at a rate of

(A(t)/(200 + t) lb/gal) * (2 gal/min) = 2 A(t)/(500 + t)

(in case you're unsure about the denominator: the tank starts off with 200 gal of solution, and each minute solution flows in at a rate of 3 gal/min and thus the tank gains (3 gal/min) * (1 min) = 3 gal. At the same time, solution flows out at a rate of 2 gal/min and thus the tank loses 2 gal, giving a net change in volume of (3 - 2)*t = t gal)

Then the net rate of salt flow is given by the ODE,

$\dfrac{\mathrm dA(t)}{\mathrm dt}-\dfrac{2A(t)}{200+t}=3$

Multiply both sides by $(200+t)^{-2}$ :

$(200+t)^{-1}\dfrac{\mathrm dA(t)}{\mathrm dt}-2(200+t)^{-3}A()=3(200+t)^{-2}$

$\implies\dfrac{\mathrm d}{\mathrm dt}\bigg((200+t)^{-2}A(t)\bigg)=3(200+t)^{-2}$

Integrating both sides and solving for $A(t)$ gives

$(200+t)^{-2}A(t)=-\dfrac3{200+t}+C$

$A(t)=-2(200+t)+C(200+t)^2$

The tank starts off with 100 lb of salt in solution, so $A(0)=100$ and we find

$100=-2(200)+C(200)^2\implies C=\dfrac1{80}$

and so

$A(t)=-2(200+t)+\dfrac{(200+t)^2}{80}=\dfrac{(200+t)(40+t)}{80}$

The tank will begin to overflow once the volume of solution reaches 500 gal; this happens when

$500=200+t\implies t=300$

or 300 minutes or 5 hours after solution starts flowing. At this point, the tank will contain

$A(300)=2125$

or 2125 lb of salt.

Theoretically, the amount of salt in the tank will increase forever, since $A(t)\to\infty$ as $t\to\infty$ .
