Step-by-step explanation:
In circle D with m \angle CDE= 122m∠CDE=122 and CD=6CD=6 units, find the length of arc CE. Round to the nearest hundredth.
Answer:
12.78 units
Step-by-step explanation:
The formula for arc length =
2πr × θ/360
From the question:
θ = 122°
r = 6 units
Therefore, the arc length =
2 × π × 6 × (122/360)
= 12.775810125 units
Approximately to the nearest hundredth = 12.78 units
Therefore, the length of arc CE is 12.78 units

–3(c – 1) = 33
please help me
Answer:
c = -10
Step-by-step explanation:
Divide both sides by -3
simplify
c - 1 = -11
add 1 to both sides
c - 1 + 1 = -11 + 1
simplify
c = -10

The green parallelogram is a dilation of the black parallelogram. What is the scale factor of the dilation?
A) 1/3
B) 1/2
C) 2
D) 3
=============================================================
Explanation:
"The green parallelogram is a dilation of the black parallelogram"
This tells us that the preimage is the black parallelogram and the image is the green one.
In short, the mapping is [tex]\text{black} \to \text{green}[/tex]
The image is smaller than the preimage (green is smaller than black), indicating the scale factor is some value of k such that 0 < k < 1. We can rule out choices C and D because of this.
--------------------
Measuring along the top, we can see that the black parallelogram goes from x = -6 to x = 8. Check out the image shown below where I've marked your given diagram, adding on helpful lines to show this going on.
The number-line distance from x = -6 to x = 8 is 14 units, so the top side of the black parallelogram is 14 units long.
The corresponding top side of the green parallelogram is 7 units long (because it spans from x = -3 and x = 4; as shown in blue in the figure below).
Divide the image length over its corresponding preimage length to get the scale factor.
scale factor = (image length)/(preimage length)
scale factor = 7/14
scale factor = 1/2
which points to choice B as our final answer.
Answer:

Circle A has center of (6, 7), and a radius of 4 and circle B has a center of (2, 4), and a radius of 16. What steps will help show that circle A is similar to circle B?
Answer:
1) Use translation to coincide the center of a circle with the center of the other circle.
2) We construct the respective loci for the circles.
3) Compare each loci by direct inspection ([tex]f(x,y)[/tex] must be the same and radii must be different but constant) to conclude the similarity of the two circles.
Step-by-step explanation:
Geometrically speaking, a circle is formed after knowing its center and radius.
1) Use translation to coincide the center of a circle with the center of the other circle. In this case, we translate the center ([tex]C_{A} (x,y) = (6,7)[/tex]) of the circle A to the location of the center of the circle B ([tex]C_{B}(x,y) = (2,4)[/tex]):
[tex]C_{A'} (x,y) = (6,7) + [(2,4) - (6,7)][/tex]
[tex]C_{A'} (x,y) = (2,4)[/tex]
2) We construct the respective loci for the circles.
By Analytical Geometric, a circle is represented by the following locus:
[tex](x-h)^{2}+(y-k)^{2} = r^{2}[/tex]
Where:
[tex]x, y[/tex] - Coordinates of a point of the circunference.
[tex]h, k[/tex] - Coordinates of the center of the circle.
[tex]r[/tex] - Radius of the circle.
3) Compare each loci by direct inspection ([tex]f(x,y)[/tex] must be the same and radii must be different but constant) to conclude the similarity of the two circles.
Then, the circles A' and B are represented by the following loci:
Circle A'
[tex](x-2)^{2} + (y-4)^{2} = 16[/tex]
Circle B
[tex](x-2)^{2} + (y-4)^{2} = 256[/tex]
Since both the [tex]f(x,y)[/tex] component of each circle is the same and radii are different but constant, then we conclude that circle A is similar to circle B.

120 sweets are put into three different size boxes.
The sweets are put into a small box, a medium box and a large box in the ratio 1:2:5
Work out the number of sweets in a large box.
Answer:
75 sweets
Step-by-step explanation:
Given that
There is 120 sweets that are put into three different size boxis
And, the ratio of small box to medium box to large box is 1:2:5
We need to find out the no of sweets in the large box
So,
The number of sweets in a large box is
= 120 sweets × 5 ÷ (1 + 2 + 5)
= 120 sweets × 5 ÷ 8
= 75 sweets
Find the length of the rectangle.
A. 10 in.
B. 20 in.
C. 27 in.
D 70 in.
Answer:
length = 10 inches
Step-by-step explanation:
We know that the perimeter of a rectangle:
P = 2(L + W), where p= perimeter, L = length, W= width, so:
34 = 2(L + 7)
=> 34 = 2L + 14
=> 20 = 2L
=> 20/2 = L
=> 10 = L

Which alternative is the NEGATIVE reciprocal of -1/8?*
A-8
B. -1/8
C. 1/8
D. 8
Answer:
Reciprocal simply means... swap the denominator for the Numerator...
Now negative Reciprocal now means... Swap the denominator by the numerator and Multiply by -1
So
1/-8 becomes
-(-8/1)
=8.
Option D
Which of these best describes π? A The area of a circle divided by its diameter. B The circumference of a circle divided by its radius. C The circumference of a circle times 3.14 D The ratio of a circle's circumference to its diameter
Answer: D. The ratio of a circle's circumference to its diameter
Step-by-step explanation:
Pi is the ratio of the circumference of a circle to its diameter which means that we get pie by dividing the circumference by the diameter. This relationship is true regardless of the size of the circle because the relationship between the circumference and the diameter does not change regardless of size.
Pi is very useful when calculating measures related to circles such as area and circumference. It also comes in handy for shapes that have circles in them such as cones.

*PLEASE HELP* A metal ornament is being designed such that its perimeter is created by four identical three-quarter circles as shown whose centers are connected to form a square. The ornament, both circular and square portions, made of wire that weighs 1.8 grams per inch. The square has sides that are 4 inches long.
Questions :
(a) Determine the total length of the circular portions in terms of
pi. Show the work that leads to your answer.
(b) Determine the total length of wire needed, both circular and
square portions, to the nearest tenth of an inch.
G
(c) Determine the total weight of the ornament to the nearest
gram.
Answer:
12π
53.68 in
96.624g
Step-by-step explanation:
The total length of the circular portion :
Perimeter of circle = Circumference of the circle = 2πr ; r = radius = 2
Size of each circle is 3/4
Number of circles = 4
Number of complete circles :
4 × 3/4 = 3 complete circles
Perimeter of circle:
Number of circles * (2πr)
3 * 2 * π * 2 = 12π
Total wore needed :
Circular + Square
Perimeter of square = 4s
s=side length = 4
Total square 4 * 4 = 16
Perimeter of Square + perimeter of circle
16 + 12π = 16 + (12 * 3.14) = 53.68 in
Total weight of ornament :
1.8 g * perimeter
1.8 * 53.68 = 96.624g

What x and y equal to
Answer:
X = 4, Y = 3.
Explanation:
Since the length of side CK is equal to the length of WM, then you can make the equation 6y-4 = 18. then you just add 4 to each side and divide both sides by six to get 3. Same thing for the other equation. Angle (i think its an angle due to its placement) C is equal to angle M, so you can make the equation 3x + 7 = 19. Subtract seven from both sides then divide by 3 to get 4. Tell me if you have any questions :)
Answer and Step-by-step explanation:
We know the triangles are congruent, so if you were to flip one of the triangles onto the other, the will perfectly match up, allowing us to solve for x and y.
19 = 3x + 7
Subtract 7 from both sides.
12 = 3x
Divide each side by 3.
4 = x
14 = 6y - 4
Add 4 to each side.
18 = 6y
Divide each side by 6.
3 = y
x = 4
y = 3
