Answer:
ways
Step-by-step explanation:
Given that a shelf contains n separate compartments. There are r indistinguishable marbles
The marbles are identical so they can be placed in any order.
Let us consider the places available for placing these r marbles
No of compartments available =n
Marbles to be placed = r
Since marbles are identical and order does not matter
number of ways the r marbles can be placed in the n compartments
= nCr
=
The angle of elavation would be 45°, this is because straight up would be represented by 180°, and 90°, would remain as 1200 ft traveled, and half of 90°, is 45° which would double the distance traveled
Answer: D. 3/2
Step-by-step explanation:
Answer:
1017 square ft.
Step-by-step explanation:
pi x r x r x h
