18.) Your answer is A.). 1,000 m is in one kilometer.

Anyone wanna help out?​
Olegator [25]

Answer:

To find out the length of AB you are trying to figure out how long it is

If B is at 45, and A is at 16

You need to figure out how far it is from 16 to 45

In order to do this the easiest way, you would go 45-16

45-16=29

AB=29

Hope this helps ;)

If I varies inversely with R and I = 0.25 when R = 18, which equation should be used to show this relationship?
pashok25 [27]
Inverse relationships are of the form xy=k or if you prefer  y=k/x so to find the constant we can say:

18(0.25)=k=4.5

So you could say: IR=4.5 or I=4.5/R
