Answer:
Step-by-step explanation:
Ratio = 4 :3
Other two sides = 4x , 3x
Pythagorean theorem
(4x)² + (3x)² = 20²
16x² + 9x² = 400
25x² = 400
x² = 400 ÷ 25
x² = 16
x = √16
x = 4 cm
4x = 4*4 = 16
3x = 3*4 = 12
Sides = 16cm , 12 cm
The earth is approximately 93,000,000 miles from the sun. If it were 10x further, it would be 930,000,000
That would place it closest to Saturn which is about 890,000,00 miles away from the sun.
To achieve balance, the momentum on both sides must be
equal so that it cancels out. Momentum is simply the product of mass and
distance, therefore:
50 pounds * 6 ft = 100 pounds * X
X = 3 ft
Hence B must be placed 3 ft from the pivot.
