Answer:
Possible lengths of the silk fibre 'x' are 100, 75, 60, 50 and 30 yards respectively.
Step-by-step explanation:
Let the length of the silk fiber = x yards.
Let the number of silk fibres = a.
It is given that the silk fibers between 3 to 10 yards are combined to form a silk thread of 300 yards.
So, we get the equation,
, where 
i.e. 
,
So, the possible values of 'a' are 3, 4, 5, 6 an 10.
Thus, the possible lengths of the silk fibre 'x' are 100, 75, 60, 50 and 30 yards respectively.
3 I'm pretty sure because it can go into both if I remember correctly that's how I was taught
Answer:
a = 16.13 ft²
Step-by-step explanation:
Triangle
a = (1/2)bh
a = (1/2)6 * 4
a = 12
Semicircle
a = (1/2)πr²
a = (1/2)(3.14)(3²)
a = 14.13
Combined figure
a = 12 + 14.13
a = 16.13 ft²

2 Simplify.
−9≤3x≤2
3 Divide the whole equation by 3.
9/3 ≤x≤ 2/3
4 Simplify.
−3≤x≤ 2/3
-3<x<4
Answer:
The last one
Step-by-step explanation:
Simply because if you have a higher negative number, the smaller the quantity.
