A large tank contains 350350 liters of a salt solution which has a concentration of 0.650.65 kilograms per liter. A salt solution which has a concentration of 0.80.8 kilograms per liter is added to the solution at a rate of 6060 liters per minute. At the same time, the solution drains from the tank at 6060 liters per minute. Find the amount SS of the salt in the solution as a function of tt:

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
