Answer:

Step-by-step explanation:

14+Sale tax=14.98

14.98-14=sale tax

14.98-14=0.98

0.98 is the sale tax now we need to find the percent

Let represent t percent

14 of t%=0.98

14*t/100=0.98

we need to use inverse operation to isolate T on one side so if its multiplication we need to do division on both sides to un-due multiplication.

So to move 100 we need to multiply on both sides and we will get

14*t=0.98*100

0.98*100=98

14*t=98

to move 14 we need to divide

14/14=1

we dont need to put 1t becuase t is =1

so we just write it as t

98/14=7

t=7

so Sale tax percent is 7%

Evaluate the integral Find the volume of material remaining in a hemisphere of radius 2 after a cylindrical hole ofradius 1 is d

algol13

You want to find the volume inside the hemisphere $x^2+y^2+z^2=4$ (i.e. inside the sphere but above the plane $z=0$ ) and outside the cylinder $x^2+y^2=1$ . Call this region $R$ .

In cylindrical coordinates, we have

$\displaystyle\iiint_R\mathrm dV=\int_0^{2\pi}\int_1^2\int_0^{\sqrt{4-r^2}}r\,\mathrm dz\,\mathrm dr\,\mathrm d\theta$

$\displaystyle=2\pi\int_1^2 r\sqrt{4-r^2}\,\mathrm dr$

$\displaystyle=-\pi\int_3^0\sqrt u\,\mathrm du$

(where $u=4-r^2$ )

$\displaystyle=\pi\int_0^3\sqrt u\,\mathrm du$

$=\dfrac{2\pi}3u^{3/2}\bigg|_0^3=2\sqrt3\,\pi$

Solve this problem please <br> x/3+6-2x=-6

Nikolay [14]

Answer:

36/5

Step-by-step explanation:

x/3 + 6 -2x = -6

multiply the whole equation by 3 to get rid of the denominator of the first x term.

x+18-6x = -18

move x terms to one side and numerical terms to the other, subtract 18 from both sides in this case

x+18-6x-18=-18-18

x-6x = -36

simplify

-5x = -36

divide both sides by -5 to isolate x

x = -36/-5

=36/5
