Answer:
40% gain.
Step-by-step explanation:
Suppose he bought 100 fruit at a cost of $40.
He sold 1/2 ($20 ) for 20 * 1.6 = $32.
He sold 1/4 ($10) for 10*1.2 = $24.
Total revenue = $56 dollars so he made 56 - 40 = $16 profit.
percent gain = 16 * 100 / 40
= 40 %.
Answer:
single solution : (4 ; 6)
Step-by-step explanation:
hello :
4x-y=10.....(1)
y=2x-2.....(2)
put the value for y in (1) :
4x-(2x-2)=10
4x-2x +2 = 10
2x=8
x=8/2 =4
but : y = 2x-2
so : y =2(4)-2=6
single solution : (4 ; 6)
b.100.48 m^3
c.33.49 m^3
d.25.12 m^3
Answer:
c.33.49 m^3
Step-by-step explanation:
Diameter = 4 meters
Radius = 4/2 = 2 meters.
Volume of sphere = (4/3)πr³
= (4/3)* 3.14 * 2 * 2 * 2
= (4 * 3.14 * 2 * 2 *2 ) / 3 = 100.48/3
= 33.49 m³
