Answer:
80
Step-by-step explanation:
Initial ratio:
Teachers to students
1 : 15
Ratio after:
Teachers to students
3 : 40
The number of students did not change, so we can make the students of the initial ratio and the students of the ratio after the same.
1 : 15 = 8 : 120
3 : 40 = 9 : 120
120 units = 1200
1 unit =
Initial teachers = 8 units =

The perimeter of the kite is (10 + 2√53) units if the kite and the coordinates of the kite are point W is at (-3, 3), point X is at (2, 3), point Y is at (4, -4), and point Z is at (-3, -2).
<h3>What is quadrilateral?</h3>It is defined as the four-sided polygon in geometry having four edges and four corners. Kite is quadrilateral, in which. Two pairs of congruent sides, and it has one pair of opposite congruent angles.
The figure is missing.
On a coordinate plane, kite WXYZ is shown (please refer to the picture)
We have a kite and the coordinates of the kite are:
Point W is at (-3, 3), point X is at (2, 3), point Y is at (4, -4), and point Z is at (-3, -2).
Using the distance formula we can find the distance between coordinates:
Distance between W and X:
WX = 5 units
Similarly, distance between X and Y:
XY = √53 units
YZ = √53 units
ZW = 5 units
Perimeter = sum of the all sides
Perimeter = 5 + √53 + √53 + 5
Perimeter = (10 + 2√53) units
Thus, the perimeter of the kite is (10 + 2√53) units if the kite and the coordinates of the kite are point W is at (-3, 3), point X is at (2, 3), point Y is at (4, -4), and point Z is at (-3, -2).
