Answer: A. 9
Step-by-step explanation:
In the given tree diagram , there are 3 branches , to each branch there are 3 leaf nodes.
By using Fundamental counting principal ,
Number of possible outcomes for the tree diagram = (Number of branches) x (Number of leaf nodes)
Hence, the number of possible outcomes for the tree diagram = 9
So, the correct option is A. 9.
Answer:
Round 4264 to the nearest hundred so the answer is 4300.
As per the problem
The escalator make a 30° angle with the floor .
The escalator have a vertical height of 36 feet.
Now draw the diagram with the given information, the diagram is attached below
From the diagram,
Horizontal length=AB=d
Distance traveled by the person on the escalator stairs=AC=l
In triangle ABC,
Again in triangle ABC, Using Pythagoras Theorem
The horizontal length needed is
The distance a person would travel on the escalator stairs is 72 ft
