COMBINED VARIATION Crossword

describes a situation where a variable on two ( or more) other variables
If y varies directly with x and inversely with z, and y = 25 when x = 10 and z = 2, find y when x = 18 and z = 9.
If y varies directly with x and inversely with z, and y = 12 when x = 100 and z = 25, find y when x = 36 and z = 12
Given the combined variation equation , find x when y = 2 and z = 10.
is a concept that is based more on the concept of ratio.
It is given that z varies directly with y and inversely with x. Also, when x = 24 and y = 48, z = 4. Find the value of z when x = 4 and y = 12
If a varies jointly as b and c and inversely as the square of d, and a = 120 when b = 5, c = 2, and d = 9, find a when b = 12, c = 9 and d = 9.
f p varies directly as the square of q and inversely as the square root of r, and p = 60 when q = 6 and r = 81, find p when q = 8 and r = 144.
the number that relates two variables that are directly proportional or inversely proportional to one another.
If xx varies directly as yy and inversely as zz , and x=10x=10 when y=5y=5 and z=3z=3 , for what value of zz will x=3x=3 and y=4y=4 ?
