Answer:
6.1
Step-by-step explanation:
Draw a picture of an equilateral triangle. Cut the triangle in half, so that you get two 30-60-90 triangles. The area of these smaller triangles is 8 square inches.
The short leg of these triangles (the base) is half the side length: ½ s.
According to properties of 30-60-90 triangles, the long leg (the height) is √3 times the short leg: ½ s√3.
Area of a triangle is half the base times the height:
A = ½bh
8 = ½ (½ s) (½ s√3)
8 = ⅛ s²√3
64 = s²√3
s² = 64/√3
s = √(64/√3)
s ≈ 6.1
Step-by-step explanation:
first cirscross it come 2nˆ4X=3L4mˆ2and divide each by 2nˆ4 to make X alone and it come, X=3L4mˆ2/2nˆ4. try my best ,if i am wrong tell me.

Answer:
The profit per year will be $23916
Step-by-step explanation:
Cost price of 1 ft³ = $2.05
Selling price of 1 ft³ = $21.98
Profit = Selling price - cost price
profit = $21.98 - $2.05
Profit = $19.93
Profit on 1 ft³ is $19.93
If they sell 100 monthly, per year (12 months), profit will be
19.93*100*12
= $23916
