1. a.$1.09, b. $2.18, c. $3.27, d. $4.36

Step-by-step explanation:

They tell you the price for 1 of something. When they ask for 2 of that same thing, you multiply that price x 2. When they ask for 3 of that same thing, you multiply that price (for 1) x 3. Same if they are asking for 7 or 11, you multiply that number times the price for one.

Does that make sense?

the first one, all those points on the line just make a strait line.

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).
