how many lines of symmetry does the quadrilateral below have.
A. 0
B. 1
C. 2
Which of the following are magnitudes for rotational symmetry of the quadrilateral below about the marked point.
A.30
B.90
C.180
D.None of the above
Answer:
C; A
Step-by-step explanation:
(coming from an 8th grader :)
1. should be A, because on each side of the quadrilateral there are two lines being mirrored.
2. should be C, because the angles are acute and not right or straight. you may be thinking “but there is a straight line” yes, you are right there’s a straight line, but there’s multiple angles consisted in making one whole angle.

I used the quadratic formula
Answer:
B
Step-by-step explanation:
Given
(x + 5)² = 48 ( take the square root of both sides )
x + 5 = ± [tex]\sqrt{48}[/tex] = ± [tex]\sqrt{16(3)}[/tex] = ± 4[tex]\sqrt{3}[/tex] ( subtract 5 from both sides )

What is the area of the shaded sector of the circle?
a. 20
b. 25
c. 100
d. 72
Answer:
i think its 25 because like if 72 is the shaded part then it can't be the answer 100 wouldn't be the answer because it is too high and 20 wouldn't be the answer because it is too low so 25 is my reasonable answer.
Step-by-step explanation:
Since the area to me is 25 then we would do 360 x 25 = 9000
the you do 9000 / 36 i got 36 by doing 360 / 10
After that you you do 9000 / 36 which gives you 2.5
Last i did 2.5 x 10 which gave me 25
Hope this helpsBrainliest plzhope you get this right
The amount Amanda earns babysitting in a month is represented by the equation a=9.5h. In the equation, a
represents the total amount Amanda earns. The number of hours she babysits is represented by h. What is the
constant of proportionality (unit rate) of a to h?
Answer:
9.5
Step-by-step explanation:
Well the constant proportionality is 9.5 because that is what makes p directly proportional to a, because when h increases, a increases, and when h decreases, a decreases.

To apply frosting to a cake, a baker twists a plastic bag containing the frosting into a cone shape with a diameter of 4.2 inches and a length of 6 inches. How many cubic inches of frosting is in the bag? Use 3.14 for pi.
Answer:27.7
Step-by-step explanation:
the formula for a cone is V=1/3πr*2h
it is 1/3 because a cone is one-third of a sphere.
you then put the information from the text in the formula and you get this
V=1/3x 3.14 (pi) x 2.1 to the power of 2 (radius is half of a diameter)x 6 (height)
then you get the answer 27.6948
round to the nearest 10th and you get
A. 27.7
Also, I took the test.
There are 27.77 in³ of frosting is in the bag.
What is volume?The amount of space, measured in cubic units, that an object or substance occupies.
Given that, To apply frosting to a cake, a baker twists a plastic bag containing the frosting into a cone shape with a diameter of 4.2 inches and a length of 6 inches.
Volume of cone = ¹/₃πr²h
r = 4.2/2 = 2.1 in
h = 6 in
Volume = ¹/₃x2.1x2.1x6
= 27.77
Hence, the volume of the cone is 27.77 in³

Half of a sphere is stacked on top of a cone. They both share a circular base. The radius of the circle is 6 millimeters. The height of the cone is 14 millimeters.
What is the volume of the composite figure? Express the answer in terms of π.
144π mm3
168π mm3
312π mm3
456π mm3
Answer:
312π mm3
Step-by-step explanation: yes
The required volume of the composite figure of the sphere on the top of the cone is 312π mm³. Option c is correct
The sphere is stacked on top of a cone. They both share a circular base. The radius of the circle is 6 millimeters. The height of the cone is 14 millimeters. The volume of the composite figure is to determine.
Volume is defined as the ratio of the mass of an object to its density.
Volume of composite figure = Volume of semi-sphere + Volume of cone
= 2/3πr³ + 1/3πr²h
= 2/3*6³π + 1/3*6²*14π
= 312π mm³
Thus, the required volume of the composite figure of the sphere on the top of the cone is 312π mm³.

Pythagorean Theorem: Jason only has room for a TV that is less than 30” wide.
Can he fit the TV in his room?
Answer:
No
Step-by-step explanation:
Using the Pythagorean Theorem, make 40 = c, 24 = b and the remaining side (the width) = a.
Solving for a we get a = [tex]\sqrt{c^2-b^2}[/tex]. Then plugging in the values for c and b, we get a = [tex]\sqrt{1024}[/tex] = 32
Since the width of the TV needs to be less than 30" wide, it will not fit since the width of the TV is 32" wide.
Answer:
No, the tv is 32 inches wide.
Step-by-step explanation:
[tex]a^{2} +b^{2} = c^{2} \\24^{2} +b^{2} =40^{2} \\40^{2} -24^{2} =b^{2} \\1600-576=b^{2} \\1024=b^{2} \\\sqrt{1024} =b\\b=32[/tex]

Consider this dilation.
(a)
Is the image of the dilation a reduction or an enlargement of the original figure? Explain.
(b)
What is the scale factor? Explain.
The letters M,S,V are the original image.
The letters M’, S’, V’ are the displayed image.
You can see that M’, S’,V’ is a smaller image, so it was a reduction.
The length of line MS is 9 units.
The length of M’S’ is 6 units.
The dialation is 6/9 = 2/3
Answer:
(a) reduction
(b) 2/3
Step-by-step explanation:
(a) The original figure is called ΔMSV, while the dilation is called ΔM'S'V'. Because we can see that M'S'V' is clearly much smaller than MSV, we know that the image is a reduction of the original.
(b) We simply need to find the ratio of one side of M'S'V' to one side of MSV. Look at M'S': the length is just 4 - (-2) = 6 (this is because it's a completely horizontal line). The length of MS is 6 - (-3) = 9.
So, the scale factor is: 6 / 9 = 2/3.
