In a video store, a DVD that sells for $15 is marked "10% off." What is the discount? What is the sale price of the DVD?

Discount : 1.5. Sales Price: 13.5

Step-by-step explanation: 10% of 15 is 1.5, your discount. Subtract your discount from 15, you get 13.5, your sales price.

what are the statements

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
