When a liquid is boiled the liquid evaporates, while the minerals settle.
Answer:11% to 2 s.f
Step-by-step explanation:
P=sp-cp over cp ×100%
Sp=€300000 cp=€270000
P=300000-270000 over 270000 ×100%
P=11.111%
11 To 2 s. f
R + g + b = 50
r = b + 6
g = b - 4
(b + 6) + (b - 4) + b = 50
3b + 2 = 50
3b = 50 - 2
3b = 48
b = 48/3
b = 16 <=== 16 blue marbles
r = b + 6
r = 16 + 6
r = 22 <=== 22 red marbles
g = b - 4
g = 16 - 4
g = 12 <=== 12 green marbles
