Romashka [77]

Answer:

SA = 680 units^2

V =1200 unit^3

Step-by-step explanation:

If the radius is 5 then the diameter is 2r = 2*5 = 10

The height would remain the same

Surface area of a prism is given by

SA = 2 (lw+lh+hw)

l =d = 10   w = d = 10   h = 12

SA = 2 ( 10*10 + 10 * 12+ 12* 10)

SA = 2( 100+120+120)

SA = 2(340)

SA = 680 units^2

V = l*w*h = 10*10*12 =1200 unit^3

A 140 gallon tank initially contains 5 lbs salt dissolved in 40 gallons of water. Brine containing 1 lb salt per gallon begins t
laiz [17]

Answer:

96.46

Step-by-step explanation:

Volume of the Gallon =140 gallons

At time t=0, V(0)=40 gallons

\frac{dV}{dt}=Rate \:In - Rate \:Out \\\frac{dV}{dt}=3\frac{gal}{min}  - 1\frac{gal}{min}  =2\frac{gal}{min}

V(t)=2t+k, Where K is a constant.

Since V(0)=40

V(0)=2(0)+k=40

k=40

V(t)=40+2t

The Change in Salt Concentration

\frac{dC}{dt}=Rate \:In - Rate \:Out \\\frac{dC}{dt}=1\frac{lb}{gallon}*3\frac{gallon}{minute}-1\frac{lb}{gallon}*\frac{C}{40+2t} \frac{gallon}{minute}\\\frac{dC}{dt}=3-\frac{C}{40+2t}

Rearranging

\frac{dC}{dt}+\frac{C}{40+2t}=3

Using Integrating Factor: e^{\int\frac{1}{40+2t} dt} =e^{ln|40+2t|}=40+2t

\frac{dC(40+2t)}{dt}=3(40+2t)

\int d[C(40+2t)]=\int(120+6t)dt\\C(40+2t)=120t+3t^2+k_0\\C(t)=\frac{120t+3t^2}{40+2t}+\frac{k_0}{40+2t}

At t=0, C(0)=0.125, k_0=5

C(t)=\frac{120t+3t^2}{40+2t}+\frac{5}{40+2t}\\C(t)=\frac{120t+3t^2+5}{40+2t}

At V(t)=140

V(t)=40+2t=140

t=50

C(50)=96.46

Just  the tank  overflows, C(t)=96.46
