Govan Limited expects to purchase 40 000 components during 2021 with a purchase price of R20 per unit, an ordering cost of R2 per order and a carrying cost of 20 percent of the unit purchase price. Use this information given below to calculate the number of orders that should be placed during 2021 using the most advantageous quantity to order each time.

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).
