AL ouis Cas Cast to find value

A triangle ABC is enlarged, about the point O as centre of enlargement, and the scale factor is 3. Find state the value of : (C’A’)/(CA)

Let a,b and c denote the sides BC,CA and AB rind the value of ABC. If |ab1ca1bc|=0 then find the value of s in^(2)A+s in^(2)B+s in^(2)C

In the extraction of Al by Hall-Heroult's process, electrolyte contains Na^+, Ca^(2+) and Al^(3+) . However only Al is discharged at cathode because,

If a+b+c=6 and ab+bc+ca=11 find the value of a^(3)+b^(3)+c^(3)-3abc

If a+b+c=9 and ab+bc+ca=26 find the value of a^(3)+b^(3)+c^(3)-3abc

Extraction of Aluminiunt can be understood by : Electrolytic reduction of Al_(2)O_(3) : {:("Electrolyte",:(Al_(2)O_(3)+"Cryolite")),("Cathode",:"Graphite inside the Fe container"),("Anode",:"Graphite rods"):} The molten electrolytes contains Na^(+),Ca^(2+), Ca^(2+) but only Al get deposited at cathode because :

In a election 60% of voters cast their votes. Find (i) The total number of voters, if 1200 voters cast their votes (ii) The number votes cast, if the total number of voters are 800

Extraction of aluminium be understood by : Electrolytic reduction Al_(2)O_(3) : Electrolyte : Al_2O_(3) + "Cryolite" + CaF_2 Carthode : Carbon inside the Fe container Anode : Graphite rods The molten electrolytes contain Na^+, Al^(3+), "and" Ca^(2+) but only Al gets deposited at cathode because,
