z varies inversely as w z=10 when w=0.3 find z when w=40 please show all your work...
so i can properly understand how you got the answer

Set up the equation first: z = k/w
Next plug in what is given to find k:
z = k/w
10 = k/.3
Multiply both side by .3
10*.3 = k
3 = k
Now rewrite the equation with the k we found:
z = 3/w
Last step; find z when w = 40
z = 3/40 = 0.075
