Question 1085184
P varies directly as q and s but inversely as t and v.
P = {{{(kqs)/(tv)}}}
P is 360 when q = 5, s = 7, t = 4, and v = 6
360 = {{{(k*5*7)/(4*6)}}}
We can write it
{{{(35k)/24}}} = 360
multiply both sides by 24
35k = 24*360
35k = 8640
k = {{{8640/35}}}
k = 246.857
" Find P=______ when q=30, s=70, t=50, and v=60"
P = {{{(246.857*30*70)/(50*60)}}} 
P = {{{518399.7/3000}}}
P = 172.72
