yuradex [85]

So if she still has $27.12, then during her call, she used a total of $2.88.

$2.88 = 288 cents.

Therefore 288 divided by 6 = 48

Therefore the answer is 48 minutes.

Arnoldo needs to write this system in slope-intercept form. Which shows how he could do that? 3 x minus 2 y = 6. 0.4 (20 y + 15)

kotegsom [21]

Answer:

y = three-halves x minus 3

Step-by-step explanation:

Subtract 3x from both sides of the original equation.

-2y = -3x +6

Divide by -2

y = 3/2x -3

The formula for the volume of a sphere is S = 4 3 πr3, where r (in feet) is the radius of the sphere. Suppose a spherical snowba

Soloha48 [4]

Answer with Step-by-step explanation:

We are given that

Volume of sphere= $\frac{4}{3}\pi r^3$

Where r= Radius of sphere in ft

a. $r=\frac{1}{(t+1)^2}-\frac{1}{15}$

$\frac{dr}{dt}=\frac{-2}{(1+t)^3}$

$\frac{dS}{dt}=\frac{dS}{dr}\cdot \frac{dr}{dt}=4\pi r^2\frac{dr}{dt}$

$\frac{dS}{dt}=4\pi(\frac{1}{(1+t)^2}-\frac{1}{15})^2\times \frac{-2}{(1+t)^3}$

$\frac{dS}{dt}=\frac{-8\pi}{(1+t)^3}(\frac{1}{(1+t)^2}-\frac{1}{15})^2$

b.Substitute t=1

Then, we get

$\frac{dS}{dt}=\frac{-8\pi}{8}(\frac{1}{4}-\frac{1}{15})^2$

$\frac{dS}{dt}=-0.1056 ft^3/min$
