8 when volleyballs are purchased, they are not fully inflated. a partially inflated volleyball can be modeled by a sphere whose

volume is approximately 180 in3. after being fully inflated, its volume is approximately 294 in3. to the nearest tenth of an inch, how much does the radius increase when the volleyball is fully inflated

The volume of the sphere by definition is:
 V = (4/3)  \pi  * r ^ 3

 Clearing the radio we have:
 r =   \sqrt[3]{ \frac{3V}{4 \pi}}
 For the initial condition we have that the radius is:
 r1 = \sqrt[3]{ \frac{3(180)}{4 \pi}}
 r1 = 3.50
 For the final condition we have that the radius is:
 r1 = \sqrt[3]{ \frac{3(294)}{4 \pi}}
 r1 = 4.12
 Then, the difference between both values is given by:
 r2 - r1 = 4.12 - 3.50

r2 - r1 = 0.62 in
 Answer:
 
the radius increase 0.62 inches when the volleyball is fully inflated

Goshia [24]

Let the  be the time in hours, and  meters of fencing completed. 

We know that After three hours, they have 15 meters of fencing complete, our graph will go from the point (0,0) to the point (3,15). We also know that they decide to take a 2-hour break for lunch and then resume building the fence, so our graph will go from the point (3,15) to the the point (5,15). Finally, After four more hours, they have a fence that is a total of 55 meters long, so the final part of our graph will go from the point (5,15) to the point (9,55)


We can conclude that the graph of t vs y is:

lianna [129]

Answer: A

n-4(32.5) > 300;n > 430tep-by-step explanation:

given that Zack wants to make a profit of more than $300 for painting 4 identical rooms. That is

Profit > $300

Then, the profit he makes is equal to the amount he is paid minus the cost of supplies. The cost of supplies is $32.50 for each room. That is

n - 32.5 and

P + 32.5 × 4

Where 4 = number of rooms

P + 130

The minimum profit = 300 + 130 = $430

Therefore, the inequality and solution that represent the dollar amount, n, that zack must be paid for each room if he is to make a profit of more than 300$ is

n-4(32.5) > 300;n > 430

During the early 20th century, in what way was the radio better than the phonograph in encouraging the concept of crosspollinati
ololo11 [35]

C. Phonograph were inferior in sound quality.

Step-by-step explanation:

Researches have shown that plants respond to the sounds of their pollinator.

Some plants begin to produce a greater amount of nectar and some begin to vibrate to attract the attention of the pollinators towards them.

Greater the intensity of the sound of the pollinator, the faster the reaction will be.

Phonographs have a sound of lower intensity when compared to the intensity of sound produced by the radio.

Thus the radio was better than the phonograph in encouraging the concept of cross-pollination.
