A 3-ply core/sheath yarn consists of a 30/1 (core) yarn, and two 20/1 (sheath) yarns. Analysis of the plied yarn showed that 1 m of the plied yarn has 1.08 m each of the two 20/1 yarns, and 1 m of the core yarn. What is cotton count of the plied yarn? Show calculations.

0.000462

Step-by-step explanation:

From the given information:

The cotton count of the piled yarn is the ratio of the simple weight in (g) with the length by the simple length with weight.

Mathematically:

b

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)
