Answer:
15. BE = 37.5
16. AD = 62.4.
17. ED = 37.5
18. Angle CDA=79 degrees
19. Angle BCD= 101.
20. Angle DAB=101.
Step-by-step explanation:
For problems 15-20, you'll use geometry theorem the definition of a parallelogram which says they have two pairs of equal parallel sides, equal opposite angles and that the diagonals in any parallelogram bisect each other into equal segments.
15. BE is half of 75. BE = 37.5
16. Since BC = 62.4 then AD = 62.4.
17. ED is half of 75. ED = 37.5
18. 79 degrees
19. Parallelograms add to 360 degrees so if two angles are 79 then 360-79-79 = 202 which is split equally in the other two angles. 202/2 =101. Angle BCD= 101.
20. Angle DAB is equal to Angle BCD so Angle DAB=101.
Yes because each X coordinate correlate with different number on y !

Answer: 60 teachers</h3>
=========================================================
Explanation:
There are 500 female students and the ratio of boys to girls is 2:5
Multiply both parts of that ratio by 100 so that the "5" turns into "500"
The ratio 2:5 turns into 200:500 showing that for every 200 male students there are 500 female students. There are 200+500 = 700 students total.
Because of this 700 figure, we'll need to multiply both parts of the ratio 3:35 by 20 so that the 35 becomes 700.
The ratio 3:35 turns into 60:700. For every 60 teachers, there are 700 students.
----------------------
Another way to solve:
The ratio of boys to girls is 2:5 which we can write as 2/5
x = number of boys
2/5 = x/500
2*500 = 5x
1000 = 5x
5x = 1000
x = 1000/5
x = 200
There are 200 boys and 500 girls, so 200+500 = 700 total.
y = number of teachers
3/35 = y/700
3*700 = 35y
2100 = 35y
35y = 2100
y = 2100/35
y = 60
There are 60 teachers
