Let the marks of Devi be x and Ali be y.
So, the equations:
2y = x <em>and</em> y + 16 = x
So,
2y = y + 16. [ because we know equals are equal to equals]
=> 2y - y = 16
=> y = 16
Check
Ali's marks are half of Devi's marks.
Devi's marks are 16 more than alis.
So, Devi's marks will be 16×2 = 32 and 32 is 16 greater than 16 (16+16=32).
The answer is 21 because I added 8 + 10+3=and I got 21
To make a frequency table, you will need to find the lowest and highest average number of movies.
Numbers go from 0.5 to 4.5.
And example of frequencies you could use are:
0-0.9 (1)
1-1.9(5)
2-2.9(5)
3-3.9(2)
4-4.9(1)
The frequencies are in parentheses beside the intervals.
The total measure of the interior angles of each figure will be:
180 (n-2) = 180 (4 - 2) = 360
Now add all those angles and set them equal to 360.
41 + 133 + 86 + x = 360
x is the unknown angle.
260 + x = 360
x = 100
The missing angle that is Not labeled in any of the figure is 100°
Hope this helps :)
The answer is 40.
1000/25 will give you the new ratio
Simple way of thinking about it
25 enlisted men = 1 officer
1000enlisted men = X officer
Cross multiply (25 by X officer and the 1 officer by the 1000)
25x = 1000
X= 40.
