Answer:
Sweater =400 grams
Hat =80 grams
Scarf =75 grams
Step-by-step explanation:
The amount of wool used to make a sweater, a hat and a scarf=555 grams
Let the amount of wool used to make a sweater be = x
The amount of wool for the sweater =x/5
The amount of wool used for the scarf=x/5 -5
Total amount of wool used = x+(x/5)+(x/5-5)
x+x/5 +x/5-5=555
Multiply all through by the LCM 5
5x+x+x-25=2775
7x=2800
x=400
Sweater =400 grams
Hat=400/5=80 grams
Scarf =400/5 -5=75 grams

Find the least common multiple of 10, 35:

The side length must be 3.454 inches, so the exact area is 11.999 inches.
<h3>
What side length the squares must have?</h3>
For a square of side length S, the area is given by:
A = S^2.
In this case, we know that the squares have an area of 12 square inches, replacing that in the area equation we get:
12 in^2 = S^2
If we apply the square root on both sides, we get:
√(12 in^2) = √S^2
3.464 in = S
This is an approximation to the side length, if each side measured this, the exact area would be:
A = (3.464 in)^2 = 11.999 in^2
Which is almost what we wanted to get.
