Speed of the train : distance traveled / time of the travel = 10.1/(0.5)=<span>20.2 mph. Hope this helped!</span>
The following
statements are true by definition:
The side
opposite ∠L is NM.
The side
opposite ∠N is ML.
The side
opposite to the angle should not contain any letter of that side.
<span>The following
statements are not essentially true because we have no idea if triangle LNM
is a right triangle (if it is, then we do not know what the hypotenuse is):</span>
The
hypotenuse is NM.
The
hypotenuse is LN.
<span>The following
statements are not true:</span>
The side
adjacent ∠L is NM.
The side
adjacent ∠N is ML.
They are not
true because the side adjacent to an angle should have its letter on the side.
For example, the side adjacent to ∠L should be LN or LM and
for ∠N it should be NM or NL.

The correct answer to your question is:
D. The volume of the cylinder is 8 times the volume of the smaller cylinder.
Answer:
The total surface area of this square pyramid is 
Step-by-step explanation:
we know that
The surface area of a square pyramid is equal to
![SA=b^{2} +4[\frac{1}{2}(b)(h)]](https://tex.z-dn.net/?f=SA%3Db%5E%7B2%7D%20%2B4%5B%5Cfrac%7B1%7D%7B2%7D%28b%29%28h%29%5D)
we have
----> the length side of the square base
----> the height of the triangular faces
substitute the values
![SA=9^{2} +4[\frac{1}{2}(9)(12)]=297\ mm^{2}](https://tex.z-dn.net/?f=SA%3D9%5E%7B2%7D%20%2B4%5B%5Cfrac%7B1%7D%7B2%7D%289%29%2812%29%5D%3D297%5C%20mm%5E%7B2%7D)
Answer:
x = - 71
Step-by-step explanation:
x - 12 = - 83
+12 +12 (adding 12 to both sides)
x = - 71
