Answer:
18.84
Step-by-step explanation:
The formula for length of the circle is =
Therefore
Therefore the Arc length =37.68/2
=18.84
prob( it lands on open end) = 8/20 = 2/5
prob ( lands on closed end) = 4/20 = 1/5
The second choice is correct.
Answer:
Step-by-step explanation:
AD = DC and BE=EC ⇒
DE = 1/2AB
- 4x + 1 = 1/2(11x - 25)
- 2(4x + 1) = 11x - 25
- 8x + 2 = 11x - 25
- 11x - 8x = 2 + 25
- 3x = 27
- x = 27/3
- x = 9
DE = 4*9 + 1 = 36 + 1 = 37
Answer:
Its plus 5
Step-by-step explanation:
8+5= 13
13+5= 18
18+5= 23
23+5= 28
Hope this helps ;)
