Answer: Co-planar
Step-by-step explanation:
There are different types of relation between circles,
Congruent circles: Two circles are congruent to each other if they have same size( radius, diameter or circumference).
Concentric circles: If two circles have the same center,
Co planar : When the two circles lie on the same plane.
Tangent circle : Circles in a common plane that intersect in a single point.
In the given diagram, AC and BD are the radius of the circle having centers A and B respectively lying on the same plane, but neither they have same size nor they have same center, Also, they are not touching to each other that's why they are not congruent, concentric and tangent,
⇒ They are only co-planer circles.
7/12 - ( 1/3 + 1/6 ) = 7/12 - 1/3 - 1/6
= 7/12 - 1/3(4) - 1/6(2)
= 7/12 - 4/12 - 2/12
= (7 - 4 - 2)/12
= 1/12
Answer: 1/12
Ok done. Thank to me :>
Problem 1
Draw a straight line and plot X anywhere on it.
Use your compass to trace out a circle with radius 1.5 cm. The circle intersects the line at two points. Let's make Y one of those points.
Also from point X, draw a circle of radius 2.5
This second circle will intersect another circle of radius 3.5 and this third circle is centered at point Z.
Check out the diagram below to see what I mean.
=====================================================
Problem 2
Draw a straight line and plot L anywhere on it.
Adjust your compass to 4 cm in width. Draw a circle around point L.
This circle crosses the line at two spots. Focus on one of those spots and call it M.
Draw another circle centered at point M. Keep the radius at 4 cm.
The two circles intersect at two points. Focus on one of the points and call it N.
The last step is to connect L, M and N to form the equilateral triangle.
See the image below.
=====================================================
Problem 3
I'm not sure how to do this using a compass and straightedge. I used GeoGebra to make the figure below instead. It's a free graphing and geometry program which is very useful. I used the same app to make the drawings for problem 1 and problem 2 earlier.
Using proportions, it is found that Monique must pay $115 on her own.
<h3>What is a proportion?</h3>
A proportion is a fraction of total amount.
In this problem, for Monique bill, we consider that:
- She has a $1,000 deductible, hence $1,000 is removed from the bill, which is now of $350, as 1350 - 1000 = 350.
- She has a 10% co-pay after the deductible, hence 0.1 x 350 = $35 is deducted from the bill, which is now of $315, as 350 - 35 = 315.
- She has already spent $200 on approved health care costs this year, which is also deducted, and the bill will be of $115, as 315 - 200 = 115.

I believe the answer would be A. 96in2
