10.)
A certain drug is made from only two ingredients: compound A and compound B . There are 7 milliliters of compound A used for every 5 milliliters of compound B. If a chemist wants to make 924 milliliters of the drug, how many milliliters of compound B are needed?
11.)
On a given planet, the weight of an object varies directly with the mass of the object. Suppose that an object whose mass is 7 kg weighs 14 N . Calculate the mass of another object that weighs 16 N .
12.)
When a constant force acts upon an object, the acceleration of the object varies inversely with its mass. When a certain constant force acts upon an object with mass 2 kg , the acceleration of the object is 33ms2. If the same force acts upon another object whose mass is 11 kg , what is this object's acceleration?
