Answer:
I'm pretty sure its 11
first orginize the numbers in numerical order
second the medj an is the middle numbe, if they are to find the mean of those two only
Answer: -42
Step-by-step explanation:
-4(n-6)+m
and then they give you the values of each
basically what you do is put the value of m into where it shows on the equation as well as the n.
-4(-5-6)+2 and then you should get
-42
Answer:
SAS
Step-by-step explanation:
GIVEN: BD=AC
angle BAD= angle ADC because they are both 90 degrees.
AB=DC because both are right triangles
Multiply both sides by 20
A nickel has a diameter of 21.21 mm and a thickness of 1.95 mm
<span>2.121 cm diameter </span>
<span>0.195 cm thickness </span>
<span>Think of a nickel as a cylinder </span>
<span>r = 2.121/2 = 1.0605 cm </span>
<span>V = pi * r^2 * h </span>
<span>V = pi * 1.0605^2 * 0.195 cubic cm </span>
<span>2 liters = 2000 cubic cm </span>
<span>2000 / (1.0605^2 * 0.195 * pi) => </span>
<span>2902.84713216 </span>
<span>Your upper limit is 2902, but it could be as little as 0 (for instance if the 2L bottle was only 1 cm wide, then you wouldn't be able to fit a single nickel in there) </span>
<span>I'd say that you could expect about a 70% packing efficiency, just off the top of my head </span>
<span>2900 * 0.7 => </span>
<span>290 * 7 => </span>
<span>300 * 7 - 10 * 7 => </span>
<span>2100 - 70 => </span>
<span>2030 </span>
<span>I'd expect around 2000 nickels would fill up the bottle quite nicely, supposing you can get the nickels into it.</span>
