Answer:
Step-by-step explanation:
The ration of weight of nickel, zinc, and copper in an alloy is 4:1:2
The weight of alloy can be written as
4x + x + 2x = 35 Kg
7 x = 35 Kg
X = 35 Kg/7
X = 5kg
The weight of nickel the alloy = 4 x 5 = 20 Kg
The weight of zinc in the alloy= 1 x 5 = 5kg
The weight of copper in the alloy = 2 x 5 = 10 kg
Answer:
Let X be the amount of each metal needed to make 35 Kg of this alloy.
We know that an alloy is composed of nickel, zinc and copper in a proportion
4:1:2. Therefore, we have:
[tex]4X+1X+2X = 35[/tex]
[tex]7X = 35[/tex]
[tex]X=\frac{35}{7}[/tex]
[tex]X=5[/tex] Kg
Therefore, there are [tex]5 \times 4 =20[/tex] kg of nickel, [tex]1 \times 5 =5[/tex] kg of zinc, and [tex]2 \times 5 = 10[/tex] kg of copper needed to make 35 kg of this alloy
