Answer:

<h2>They are proportional.</h2>

Step-by-step explanation:

The ratios are

\frac{48}{72} and \frac{6}{9}

To demonstrate if they are proportional, both must be equivalent. So, let's find out:

\frac{48}{72}=\frac{6}{9}

If we simplify each fraction, we have:

\frac{6}{9}=\frac{6}{9}\\\frac{2}{3}=\frac{2}{3}

As you can see, both ratios are equivalent, this mean that they are proportional, and the constant of proportionality is \frac{2}{3}.

Therefore, they are proportional.

Show that the maximum rate of change, with respect to radius, of the volume of a deflating balloon is four times the sphere's in
dmitriy555 [2]

Step-by-step explanation:

Let's say R is the initial radius of the sphere, and r is the radius at time t.

The volume of the sphere at time t is:

V = 4/3 π r³

Taking derivative with respect to radius:

dV/dr = 4π r²

This is a maximum when r is a maximum, which is when r = R.

(dV/dr)max = 4π R²

This is 4 times the sphere's initial great circle area, but not the great circle circumference.  The problem statement contains an error.

Allen traveled for 7 hours at a constant rate of 40 miles per hour. Anna traveled the same distance at a constant rate of 50 mil
TEA [102]

Here is the correct order of the step:

Identify: Anna's time is the unknown

Strategize : let x = Anna's time

Set up : 7(40) = x(50)

Solve: x = 5.6

Check: 7(40) = 5.6(50)

<h3>What is Anna's time?</h3>

The first step is to determine the distance Allen travelled:

Distance = average speed x time

40 x 7 = 280 miles  

The second step is to determine the time it took Anna to travel 280 miles.

Time = distance / average speed

280 / 50 = 5.6 hours
