Answer:
The greatest common factor (GCF) of 18 and 20 is 2.
Step-by-step explanation:
To solve this problem, first, you have to find the greatest common factor of 18 and 20.
Factors of 18:
1, 2, 3, 6, 9, and 18.
Factors of 20:
1, 2, 4, 5, 10, and 20.
So, the greatest common factor (GCF) of 18 and 20 is 2.
Answer:

Step-by-step explanation:
An apothem is a perpendicular drawn from the centre of the triangle to one of its sides.
The three apothems OD, OE, and OF divide ∆ABC into six smaller congruent triangles.
1. Area of ∆OCD
CotOCD = OD/OC
cot30 = CD/6
√3 = CD/6
CD = 6√3
A= ½bh
A = ½ × 6√3 × 6 = 18√3 in²
2. Area of ∆ABC
A = 6 × area of ∆OCD = 6 × 18√3 = 108√3 in²

0.01907407 lbs per second is the answer I think
90/105... divide the top and bottom by 5 so you get 18/21 then divide by 3 so you get 6/7 or just divide by 15 at the beginning and get 6/7. The answer is 6/7
