Petrolyn motor oil is a combination of natural oil and synthetic oil. it contains 5 liters of natural oil for every 7 liters of synthetic oil. in order to make 672 liters of petrolyn oil, how many liters of natural oil is needed?

518,400

step-by-step explanation:

the area is multiplying all the given measurements together.

40 * 18 * 30 * 24 = 518,400

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
