Quadrilateral opqr is inscribed in circle n, as shown below. which of the following could be used to calculate the measure of ∠pqr? circle n is shown with a quadrilateral opqr inscribed inside it. angle o is labeled x plus 16. angle p is not labeled. angle q is labeled 6x minus 4. angle r is labeled 2x plus 16. (6x − 4)° + (2x + 16)° = 180° (x + 16)° + (6x − 4)° = 180° (6x − 4)° + (2x + 16)° = 360° (x + 16)° + (6x − 4)° = 360°

Aschool typically sells 500 yearbooks each year for 50 dollars each. the economic calls does a project and discovers that they can sell 100 more yearbooks for every $5 decrease in price. the revenue for yearbook sales is equal to the number of yearbooks sold times the price of the yearbook. let x represent the number of $5 decrease in price. if the expression that represents the revenue is written in the form r(x)=(500+ax)(50-bx). to maximize profit, what price should the school charge for the yearbooks? what is the possible maximum revenue? if the school attains the maximum revenue, how many yearbooks will they sell?
