Answer:
480 students
Step-by-step explanation:
600 x .80
The answer is 2/3 because 3/8x16/9= 2/3
All the triangles are similar, so the ratio of (long leg)/(short leg) is the same. The long leg of ΔADB is
.. AD = AC -DC = 20 -4
.. AD = 16
Then
.. (long leg)/(short leg) = AD/DB = BD/DC
.. 16/h = h/4
.. h^2 = 64
.. h = 8
Selection D is appropriate.
_____
You may see this again. The altitude (h) from the right angle in a right triangle is the geometric mean of segments AD and DC. That is,
.. h = √((AD)*(DC))
The answer is d, just find the equation and then plug in the first few numbers of copies and you’ll find the correct answer
mark me brainliest if the answer is correct, thank you in advance :)
