Answer:
Step-by-step explanation:
perp. -3/2
y + 1 = -3/2(x - 4)
y + 1 = -3/2x + 6
y = -3/2x + 5
The metallurgist must use 5.538 pounds of an alloy with 39 % copper and 42.462 pounds of an alloy with 62 % copper.
<h3>How to calculate proportions of components associated to an alloy</h3>
Herein we must create a new alloy by using correct quantities of two alloys with distinct <em>copper</em> concentrations. All required information can be found by concept of <em>weighted</em> averages:
(62/100) · (48 lb) = (39/100) · x + (65/100) · (48 - x)
62 · 48 = 39 · x + 65 · 48 - 65 · x
3 · 48 = 26 · x
x = 5.538 lb
