Astore sells rope by the meter. the equation p=0.8l represents the price p (in dollars) of a piece of nylon rope that is l meters long

the cost of the rope is $ .80/meter  ( or 80 cents per meter)

Step-by-step explanation:

If p = 0.8L,  

and p is in dollars

i got 10.28 but that rounds up to 10.3

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).
