Solution:
30% of the employees are managers.
Explanation:
We have been given that there are 80 employees, and 24 of the employees are managers.
We have to find the percentage of the employees that are managers.
We can find this percentage with the below formula

On substituting the known values, we get

Therefore, 30% of the employees are managers.
27
you multiply .30 times 90 and you get 27
We know that
in a right triangle
Applying the Pythagoras Theorem
c²=a²+b²
in this problem
c=√87 yd
a=√23 yd
b=?
so
b²=c²-a²-----> b²=(√87)²-(√23)²----> b²=87-23----> b²=64----> b=8 yd
the answer is
8 yd
