w = km, where w is weight, m is mass and k is a constant
given: when w = 54 , m = 6
54 = k(6)
k = 9
so w = 9m, so if m = 8, w = ...
or, just use a proportion:
x/54 = 8/6
x = 54(4/3) = ... same as above
The weight of an object exerts on a scale varies directly with the mass of an object. If a bowling ball has a mass of 6 kg, the scale reads 54.
If another object has a mass of 8kg, what would the scale read?
