Write each fraction as a mixed number. <br> 5 3/5<br> 3 4/9 <br> 43/9<br> 32/5
AURORKA [14]

Answer:

5 3/5 is already a mixed number

3 4/9 is also already a mixed number

43/9 = 36/9 + 7/9 = 4 7/9

32/5 = 30/5 + 2/5 = 6 2/5

Solve for x 4x+ 14=6x-8
Tomtit [17]

x=11
x is equal to 11 because you subtract 4x from both sides and then add 8 to both sides where you are left with 2x=22. After dividing by 2, you get x=11

Sand is leaking through a small hole at the bottom of a conical funnel at the rate of 12cm3/s . if the radius of the funnel is 8
Bezzdna [24]

Answer:

h ≅ 16.29 cm

\mathbf{\dfrac{dh}{dt}= -0.1809 \ cm/s}

Step-by-step explanation:

From the conical funnel;

Let the adjacent line at the base of the cone be radius (r) and the opposite ( vertical length) be the height (h)

Then;

tan  \theta= \dfrac{r}{h}

tan  \theta= \dfrac{8}{16}

tan  \theta= \dfrac{1}{2}

∴

\dfrac{r}{h} = \dfrac{1}{2}

r = \dfrac{h}{2}

The volume (V) of the cone is expressed as:

V = \dfrac{1}{3}\pi r ^2 h

V = \dfrac{1}{3}\pi (\dfrac{h}{2})^2 h

V = \dfrac{\pi h^3}{3\times 4}

\dfrac{dv}{dt} = \dfrac{3 \pi h^2}{3 \times 4} \dfrac{dh}{dt}

\dfrac{dv}{dt} = \dfrac{ \pi h^2}{4} \dfrac{dh}{dt}

Given that:

\dfrac{dv}{dt} = 12 \pi

Then:

-12 \pi = \dfrac{ \pi h^2}{4} \dfrac{dh}{dt}

- \int 48 \ dt = \int h^2 \ dh

\dfrac{h^3}{3}= -48 t + c

At  \ t = 0 \  ; h = 0

∴

\dfrac{0^3}{3} = -48(0) + c

c = 0

So;

\dfrac{h^3}{3}= -48 t + 0

\dfrac{h^3}{3}= -48 t

t = 30

\implies h = (-48(30))^{1/3}

h = 16.2865

h ≅ 16.29 cm

Thus;

from -12 \pi = \dfrac{ \pi h^2}{4} \dfrac{dh}{dt}

\dfrac{-12 \pi} { \dfrac{ \pi h^2}{4} } =\dfrac{dh}{dt}

\dfrac{dh}{dt} = \dfrac{-12 \pi} { \dfrac{ \pi h^2}{4} }

\dfrac{dh}{dt}=\dfrac{-12 \times 4} { {16.29^2} }

\mathbf{\dfrac{dh}{dt}= -0.1809 \ cm/s}
