Question

For a group of objects of the same material, the weight of an object varies directly with its volume. If an object that has a volume of 30 cubic inches weighs 24 ounces, what is the constant of variation?

Answer 1

Answer:

4/5 oz / cu in

Step-by-step explanation:

The standard equation of direct variation is:

y = kx

where y varies directly with x, and k is the constant of variation.

24 oz = k * 30 cu in

k = 24/30 oz / cu in

k = 4/5 oz / cu in
