A new alloy is made by mixing 8 parts of iron, 3 parts of zinc, and one part of tungsten. how much of each metal is needed to make 420 m3 of the alloy

Iron: 280m³

Zinc: 105m³

Tungsten: 35m³

Step-by-step explanation:

8+3+1 = 12

(8/12)×420 = 280

(3/12)×420 = 105

(1/12)×420 = 35

answer: i believe its b. if you sound out the sentences that sounds wrong.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
