Frederick wants to save 30% of his earnings he earns $80 each week he thinks he needs to save $2.40 each week is fredrick correct justify your answer

Frederick is not correct.

Step-by-step explanation:

30% of $80 is $24, not $2.40. The math can be done by taking 80 and multiplying it by .3 (which is 30% in decimal form). This gives you $24.

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).
