Answer:
20
Step-by-step explanation:
The cost of the x mangoes was ...
c = 10(x/4)
The revenue from the sale of mangoes was ...
r = 20(x-5)/5
The profit is the difference between revenue and cost:
10 = r - c = 20(x -5)/5 -10(x/4) = 1.5x -20 . . . . substitute and simplify
30 = 1.5x . . . . . add 20
20 = x . . . . . . . .divide by 1.5
The trader bought 20 mangoes.
_____
<em>Check</em>
He paid 20(10/4) = 50 naira. He sold the 15 good mangoes for 20/5(15) = 60 naira, so made a 10 naira profit.
The complete question in the attached figure
we know that
radius r of a circle=4 units
in the triangle OST
OT=OS=4 units
m∠OST = 60°
cos 60°=(ST/2)/r-------> ST=2*r*cos 60°-----> 2*4*(1/2)----> 4 units
so
triangle OST
<span>it's an equilateral triangle
</span>
the answer Part a) is ST=4 units
Part b)
Find PT
in the triangle POT
m∠POT = (180°-60°)---------> 120°
m∠OTP = 30°
cos 30°=(PT/2)/r------> PT=2*r*cos 30°------> 2*4*√3/2----> 4√3 units
the answer Part b) isPT=4√3 units
