We have that F is proportional to m1. Hence, we have that F=m1*c when we change the first mass. We also have that F=m2*c when we only change the 2nd mass. Since F scales inversely with the square of the distance, we have that
. Combining all of the facts above, we get that F=c*
where c is a constant.
<em>b = 36.0</em>
Step-by-step explanation:
These two triangles are similar, so they can have a ratio that is equal to one another. We need to pick a side on one of the triangles and match the corresponding side on the other triangle, an example of this would be 6/27. Something like 6/45 would be incorrect since they are totally different corresponding sides. For the other side of the ratio, you will want to keep the same pattern. So if you do the left triangle first in the first ratio, keep it the same for the other. An example of this would be 6/27 = 8/b. It would be incorrect to put 6/27 = b/8.
There are numerous different ratios you can do but this is the one I did...
Notice how I used both of the triangles corresponding sides and followed the pattern of which triangle came first.
Now we can solve by cross multiplying.
Divide.

Answer:
the first one is 0.08 second 0.06 third 0.04 fourth 0.035
Step-by-step explanation:
just divide total cost by amount
Answer:
112 $ is the original price
Step-by-step explanation:
you have to think that the original price multiplied by 0.75 (also known as 75%) gave the result of what he saves i.e 84 $. So we put up an equation with the original price multiplied by 75% which equals the 84 $ he saved on buying that item on sale
Just round them then add together
