In the given rectangle Angle ROS is 105°

Given:

Angle RPQ=30°

To find:

The angle ROS

Solution:

The angle ROS=120°.

We know that the rectangle's diagonals are having an equal length and they also divide each other into two equal halves.

So, OP=OR and OQ=OS.

Also, OP=OQ and OR=OS.

Now, in ΔPOQ,

Angle SQP=angle RPQ (corresponding to equal sides OP and OQ)

So, angle SQP=30°

Angle SQP+angle RPQ+angle POQ=180°

Using values,

30°+30°+angle POQ=180°

60°+angle POQ =180°

angle POQ=180°-60°

angle POQ=120°

Now, lines PQ and RS are parallel and PR, QS intersect at O.

So, angle POQ=angle ROS (one another's vertically opposite angle)

Angle ROS=120°

Therefore, the angle ROS=120°.

Answer:

Consider three processes, all arriving at time zero, with total execution time of 10, 20 and 30 units, respectively. Each process spends the first 20% of execution time doing I/O, the next 70% of time doing computation, and the last 10% of time doing I/O again. The operating system uses a shortest remaining compute time first scheduling algorithm and schedules a new process either when the running process gets blocked on I/O or when the running process finishes its compute burst. Assume that all I/O operations can be overlapped as much as possible. For what percentage of time does the CPU remain idle?

(A) 0%

(B) 10.6%

(C) 30.0%

(D) 89.4%
