The distance covered by a free-falling object in 'T' seconds after it's dropped is
D = (1/2) x (gravity acceleration) x (T²)
Gravity acceleration on Earth is 9.8 m/s². or 32.2 feet/sec² .
20-ft = (1/2) (16.1) (T²)
20 = 8.05 T²
T = √(20/8.05) = <u>1.576 seconds .</u>
Answer:
-2x - 5 (lesser than or equal to) 15
26*1/8=13/4
<span>1/8 ×2=1/4
</span><span>4×13=52
</span><span>1/4×3=3/4
</span><span>13×1/4=3/14
</span>
I'd say the answer is none <span />
Hello!
To find the perimeter you add all the sides
2l + 2w = 12
Put in numbers that work
length - 2
width - 4
length - 1
width 5
length - 1.5
width - 4.5
These are three rectangles that work
Hope this helps!
Its just simple subtract the p to 7p you will get 6p .
