Answer:
81
Step-by-step explanation:
Set up a proportion to find how many total students there are [notice how females are on top and totals are on the bottom of the ratios]
=
so cross multiply 4x = 396(9) so x = 891, if there are a total of 891 students and you need 1 teacher per 11 students then take 891/11 so you need 81 teachers.
You could set up another proportion 1/11 = x/891
Answer:
18, 72
Step-by-step explanation:
Two angles are complementary if they sum up to 90°. Call them
. From the second part,

The second angle is 
Answer:
C
Step-by-step explanation:

To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
The domain of the function g(x) is x >= 5
<h3>How to determine the domain?</h3>
The complete question is added as an attachment
From the graph, we have the smallest value of x to be 5.
And the value of x increases to the right
This means that:
x >= 5
Hence, the domain of the function g(x) is x >= 5
