Answer:
answer is b
Step-by-step explanation:
Presuming the rooms are connected to each other by a door and that each room has two doors, you will potentially check in;

= 756 rooms
We are subtracting 1 since the last door doesn't lead to another room.
1.Move the decimal place to the left to create a new number from 1 up to 10.
2.Determine the exponent, which is the number of times you moved the decimal.
3.Put the number in the correct form for scientific notation
A) 0.955 and 199/200
B) 1.40 or 1.4 and 1 2/5
C) 0.90 or 0.9 and 9/10
The answer is
-5/8+9/2=3 7/8 or 31/8
so you should put 31 in the green box
