If 18 copies cost $1.08, then 30 copies will cost how much?

2.70$

Step-by-step explanation

If you take 1.08$ and divied it by 18 you will get 0.135$, and you need 12 more copies to make 30 copies so you multiply 0.135$ by 12 and get 1.62$ and then you add 1.62$ to 1.08$ and you get 2.70$.

54.864 meters

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).
