Answer:
<em>8 more men are needed to complete the job</em>
Step-by-step explanation:
<u>Proportions</u>
This problem can be solved by step-by-step reasoning applying proportions:
- 16 men working 9 hrs a day complete the job in 14 days
- 16 men working 1 hr a day complete the job in 14*9 days
The above statement stands because the fewer hours of work, the more time the job needs to be completed. Let's continue.
- 1 man working 1 hr a day complete the job in 14*9*16 days
The same reasoning applies here, fewer men=more days.
Now for the second condition. Increase the hours/day:
- 1 man working 7 hrs a day complete the job in 14*9*16/7 days
More hours/day=less days to complete the job
- x men working 7 hrs a day complete the job in 14*9*16/(7*x) days
We know this last time is 12 days, thus:
Solving for x:
24 men are needed now, this is an increase of 24-16=8 more men
8 more men are needed to complete the job
The intersection of the perpendicular bisector of GF and the angle bisector of ZE inside the quadrilateral.
What is a quadrilateral?
quadrilateral is a plane mathematical closed figure consist of four side and four edges. There are 7 types of quadrilateral
a) Trapezium,
b) Parallelogram,
c) Rectangle,
d) Rhombus,
e) Square,
f) Kite
as the given figure is unknown with dimension it is difficult to find the measurement but it is be to noted that the perpendicular bisector of GF and angle bisector of angle E will intersect at some point inside the given quadrilateral.

I'm not going to give you the answer, but I'm going to give really obvious hints to you.
Supplementary angles are when two angles add up to 180 degrees.
Complimentary is when two angles add up to 90 degrees.
I'm not sure how you find angles m<y and m<v, I can't even see the letter m on the attachment.
There are two angles that are adjacent to <GXF, and you are free to choose which ever ones you like: <FXE and <CXG
The correct answer is it is a figure with at least 3 straight sides. When you think of a square or a triangle they both have at least 3 sides that are straight. A circle doesn't have any straight sides so it is not a polygon.
You can prove that the other answer is wrong because of two things:
The definition of a polygon is a plane figure with at least three straight sides.
Also, when you think of most shapes what do they all have in common? The have at least three straight sides
So, since averages are defined as:
So, since P are the total number of elements and P_k is the P_kth student. This is saying if we sum over each student's score and divide it by the number of students, we should get P, which is true.
So, using that logic, the other class can be represented as:
We can take both of these equations and multiply them by N:
So, if we want to find the average of this we should add both our equations then divide by P+N, which is the number of all the students.
To make this simpler we can replace our LHS with 86, since that's the average of both classes combined.
Simplified we would have P/N=3/8.
