Answer:
260%
Step-by-step explanation:
For the coffee;
cost price () = $5/kg
selling price () = $18/kg
Percentage profit (%P) = %
Substitute the right values into the above;
%P = %
%P = %
%P = 260%
Therefore, the percentage profit compared to the original cost of the coffee is 260%
Answer:
m∠B = 43°
b = 26.1
c = 38.3
Step-by-step explanation:
By applying triangle sum in the given triangle,
47° + 90° + m∠B = 180°
137° + m∠B = 180°
m∠B = 43°
By applying sine ratio to the angle measuring 47°.
sin(47°) =
=
c =
c = 38.28
c ≈ 38.3
By applying cosine rule,
cos(47°) =
=
=
b = 38.3[cos(47°)]
b = 26.1
