The answer is actually 28 because if you put 5 instead of d you multiply 4 x 5 equals 20 plus 8 equals 28 :)
You could factor 4d+8. This would be 4(d+2)

In the accounting department at a university, 60% of the students are women and 250 of the students are men. How many accounting students are there in all?
Answers
There would be 625 students because 40% of students would be 250. If you divide 250 by 2 you get 125 which is 20%. Then you would multiply 125 and 5 and get 625.
In the given figure , if angel ROQ = 90 and angel POS : angel ROS = 4 : 5 , then the value of angel SOQ is
Answers
First of all, these are angles. 'Angels' don't pop up too often in math.
ROQ is 90°.
Then POR is also 90°.
POS : ROS = 4 : 5
So if you split up POR into (4 + 5) = 9 pieces, POS is 4 of them and ROS is 5 of them.
Since POR is 90°, each piece is 10° .
POS = 40° and ROS = 50° .
SOQ is ROS added onto ROQ.
ROQ = 90° ROS = 50° ------------------ SOQ = 140°
