An alloy composed of nickel, zinc, and copper in a 4: 1: 2 ratio. how many kilograms of each metal are needed to make 35 kg of this alloy?

the required amount of nickel is
kg .
the required amount of zink is
kg .
the required amount of copper is
kg .

Step-by-step explanation:

The total number of parts is 4 + 1 + 2 = 7.

Nickel is 4/7 of the mass: 4/7 × 35 kg = 20 kg.

Zinc is 1/7 of the mass: 1/7 × 35 kg = 5 kg.

Copper is 2/7 of the mass: 2/7 × 35 = 10 kg.

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

it is 10.6 according to my calculations
