Conguence is mantained, because reflection preserve distances and angles.
Orientiation is not preserved. You can check this yourself: try to look at a watch through a mirror. You will see it going counterclockwise.
Answer:
the scale factor is 25, 3000/125 scaled down,
Step-by-step explanation:
you can also explain this with a 25:1 ratio, 25 inches from the original scaled to 1 inch for the photo copy.
Answer:
It is a little bit trivial:
As we know:
Energy sink: is anything that uses energy.
Energy source: is anything that produces energy.
How the caol deposits can be energy sinks? well, you want to extract the coal from those deposits, and to do it, you need to "use energy" (the type of energy can depend on the extraction method, for example, if you use a pickaxe to extract the coal, you are using mechanical energy)
These coals are potential energy sources because coal is an energy source, potential means that, given some circumstances, something can transform into other things.
So potential energy source in this situation means that those coal deposits can be potential energy when we extract the coal and use it as an energy source.
X=invested at 10%12000-x=invested at 15% .10x+ (.15)(12000-x)=1440 ;; 12% of the total amount is 12% of $12000. .10x + 1800-.15x=1440
-0.05x=-360x=7200 12000-x=4800 $7200 at 10%=$720$4800 at 15%=$720 That is $12000 earning $1440, and that is 12%
Answer:
The correct answer is 11°F.
Step-by-step explanation:
To solve this problem, we simply need to find the change in temperature. This is modeled below:
Change in temperature = final temperature - initial temperature
Change in temperature = 57 - 46 = 11
Therefore, the correct answer is 11 degrees Fahrenheit.
Hope this helps!
