Answer:
70%
Step-by-step explanation:
I'm sorry but I don't really know how to explain it other than 70% of 30 is 21 so that means that 30% of the students turned their essay in on time.
(sorry for not being able to explain it but I hope it helped)
in order to know the greatest common multiple of 84 you would have to compare it to another number
Step-by-step explanation:
It's a question of trigonometry.
You need to remember that tangent (tan) stands for Perpendicular / Base.
So, tan P = QR / PR
By Pythagoras Theorem,
34² = 30² + x²
x² = 34² - 30²
x² = 1156 - 900
x² = 256
x = 16
Now, placing the values,
tan P = 30 / 16
tan P = 1.875

Answer:
N0 solution.
Step-by-step explanation:
x=-2y+1....(1)
x+2y=9....(2)
put equation (2) to equation (1)
-2y+1 + 2y=9
combine
-2y + 2y=9-1
0=8
No solution.
