Answer:
The volume of water needed=0.86 liters
Explanation:
Step 1: Form an equation
The equation can be expressed as follows;
(Ac×Va)+(Wc+Vw)=Fc(Va+Vw)
where;
Ac=initial concentration of antifreeze
Va=volume of antifreeze in liters
Wc=concentration of water
Vw=volume of the water in liters
Fc=final concentration of the antifreeze
This expression can be written as;
(concentration of antifreeze×volume of antifreeze in liters)+(concentration of water×volume of the water)=final concentration of the antifreeze(volume of antifreeze in liters+volume of the water in liters)
In our case;
Ac=45%=45/100=0.45
Va=3 liters
Wc=0
Vw=unknown
Fc=35%=35/100=0.35
Replacing;
(0.45×3)+(0×Vw)=0.35(3+Vw)
1.35=1.05+0.35 Vw
0.35 Vw=1.35-1.05
0.35 Vw=0.30
Vw=0.3/0.35=0.86
Vw=0.86 liters
The volume of water needed=0.86 liters
The answer is: the system is owned by the banks.
Even though the name contain the word 'federal' , the federal reserves are not entirely owned by the government. Several banks owned percentage of ownership to the federal reserve. Government officials only acted as the Board of Directors, not the owner. Because of this dis attachment, the federal reserve could had high degree of political independence
