Problem 8
The triangles are congruent, which means their corresponding pieces must also be congruent.
angle A = angle Dangle B = angle Eangle C = angle FFocus on the second equation above. We can further say
angle B = angle E
E = B
12x+30 = 50
12x = 50-30
12x = 20
x = 20/12
x = 10/6
----------------
Now move to the equation involving C and F to get
F = C
(y/2) - 10 = 40
y/2 = 40+10
y/2 = 50
y = 2*50
y = 100
----------------
And finally,
D = A
sqrt(z) = 90
z = 90^2
z = 8100
=======================================================
Problem 11
The radius of the circle is r = 5.
The area of the circle is A = pi*r^2 = pi*5^2 = 25pi
The diameter of the circle is 2*r = 2*5 = 10, which is the side length of the square because the circle is fit perfectly inside the square.
Since the square side length is 10, the area is 10^2 = 100
Subtract the two areas: large-small = square - circle = 100 - 25pi
We subtract the areas because we're basically kicking out the circle area when we don't shade it. Think of it like sawing out that portion of a wooden block perhaps.
=======================================================
Problem 19
Part (a)
The point P is directly below the center and it is on the circle.
The location of point P is (18,0) because the x coordinates of both points are the same (so that P is directly below the center) and P resides on the x axis. All points on the x axis have y coordinate 0.
------------------------------
Part (b)
The radius of the circle is r = 10 which is the distance from the center to point P.
The area of the circle is therefore A = pi*r^2 = pi*10^2 = 100pi
Answer: 100pi

Step-by-step explanation:
By Order of Operations, You read it left to right since Multiplication and Division are of the same importance. You would start with 15/3, which is 5.
Then your equation would be: 5*7/20.
Again, you would just read it left to right, 5*7=35
Then divide by 20, which is 1.75.

Find the quotient. 6 1/2 divided by 3 2/3
Answers
Answer:
Multiply both numbers by 10 and create a fraction. Then simplify that fraction by dividing both top and bottom by the greatest common factor.
Step-by-step explanation:
Treating 3 1/2 as 3.5 you could set up the fraction as such.
3.5 x 10 = 35
21 x 10 = 210
so you have the fraction 35/210. The GCF of the top and bottom is 35. There is one 35 in 35 and six 35s in 210
So the fraction in the simplest form is 1/6. So the quotient is 1/6.

Answer:
Jason would have to work 60 hours.
Step-by-step explanation:
The equation you would use would be 450 + 12.50t = 1200.
1200 is the money needed, 450 is a constant factor, but the 12.50 changes depending on how many hours Jason works.
You will have to use inverse operations so you would go 450 + 12.50t - 450 = 1200 - 450. That equals 12.50t = 750. Then you divide 12.50 by 750 because 12.50t is multiplying. 750 ÷ 12.5 = 60. So Jason has to work 60 hours!
