Answer:

I am pretty sure it's 495

Step-by-step explanation:

The context of this problem makes me think that the order in which the sites are in does not matter

if that's the case we can solve this using combinations

the combinations formula is as follows:

ACB= \frac{A!}{(A-B)!*B!}

so 12C4= \frac{12!}{(12-4)!*4!}=495

nasty-shy [4]
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
Yes, the 3 feet are important. 
<span>You can consider the datum (y=0) at 3' from the ground, and the ground is therefore at -3 feet. </span>

<span>The vertical initial velocity, vy, is u*sin(θ), so it gives </span>
<span>vy=55sin(44°)=38.21 approx. </span>

<span>The (vertical) distance travelled is given by: </span>
<span>S=vy*t-(1/2)gt² </span>
<span>where </span>
<span>S=-3 (ground) </span>
<span>vy=55sin(44°), and </span>
<span>g=32.2 ft/s² </span>
<span>Solve for t. </span>
<span>I get -0.08 and 2.45 s.</span>

Tennis balls are packed into a square box 23cm on one side. The tennis balls can be touching, but they can't be compressed. (1in
victus00 [196]

Answer:

The problem stats you cannot compress the balls; so you can not round up. You must round down. That means 4 x4 x4. There will be 16 balls per layer and 4 layers. So 48 balls.

The volume of the box is 12%5E3 inches.

 

You are told the diameter of a ball is 2.5 inches. So the radius of a ball is 1.25 inches

The volume of each ball is %284%2F3%29pi%2Ar%5E3

Subtract the volume of 16 balls from the volume of the box to get the volume of the packing bead material

To get the percentage of beads to box, divide the bead volume by the box volume and multiply by 100%
