Answer:
A
Step-by-step explanation:
First we need to find the perimiter of a parallelogram
Side A is the slanted line,
Side B is the 2 horizontal lines.
The equation for this is 2(a+b)
Let's plug in the measurements:
2(18+27) =
2(45) =
90
So the parallelogram is 90 now we have the perimeter of the semi cirlce already which is 18
90 + 18 = 108
Hope this helps :)

(geometry) This zigzag crystal vase has a height of 12 inches. The cross sections parallel to the base are always rectangles that are 5 inches wide by 4 inches long.
(a) If we assume the crystal itself has no thickness, what would be the volume of the base?
(b) The crystal is actually half an inch thick on each of the sides and on the bottom. Approximately how much space is contained within the vase?
Answers
Answer:
A. 9
B. 7
Step-by-step explanation:
a) The volume of the base of the crystal is 240 inches³
b) The space contained by the vase of the crystal is 24 inches³
What is the volume of a Cuboid?A cuboid is defined as a three-dimensional shape, that has six rectangular faces, eight vertices and twelve edges
The volume of a cuboid is the product of its length , width and height
The volume of the cuboid is given by
Volume of Cuboid = Length x Width x Height
Given data ,
(a) Since the cross sections are always cuboids that are 5 inches wide by 4 inches long, the area of each cross section is 5 x 4 = 20 square inches. Since the vase has a height of 12 inches, the volume of the vase is equal to the product of the area of the base and the height, which is 20 x 12 = 240 cubic inches.
(b) If the crystal is half an inch thick on each of the sides and on the bottom, then the dimensions of each cross section are 5 inches by 4 inches by 1 inch (since each side of the crystal adds half an inch to the length and width of the rectangle). The volume of each cross section is therefore 5 x 4 x 1 = 20 cubic inches.
However, since the crystal takes up half an inch on each side, the actual space contained within the vase is reduced by 2 x (5 + 4 + 0.5 + 0.5) x 12 = 216 cubic inches (where 5 + 4 is the sum of the lengths and widths of the rectangle, and 0.5 + 0.5 is the thickness of the crystal on each side).
Hence , the approximate space contained within the vase is 240 - 216 = 24 cubic inches

Can someone please help I asked earlier but no one is answering!
Answers
Answer:
a) 4x+6
b) 28
Step-by-step explanation:
The perimeter is equal to 1+x+1+x+1+1+1+x+1+x.
Simplifying we have 4x+6.
If we plug in 5.5 for x, we get 4*5.5+6=28

Answers
Answer:
8/20*6/20=3/25
the probability is 3/25
For Oreos, you have 8 in the basket so you divide 8 by how many is in the basket to get 2/5.
Then you divide 6 by the total amount which is 6/20 to get 3/10.
What is the value of x and the measure of ∠WZX, respectively?
A. x = 34 ; ∠WZX = 43
B. x = 43 ; ∠WZX = 34
C. x = 50 ; ∠WZX = 41
D. x = 41 ; ∠WZX = 50
Answers
Answer:
x = 43
Step-by-step explanation:
Supplementary angles = 180°
So,
(3x + 17) + (x - 9) = 180°
Combine like terms:
4x + 8 = 180
Subtract 8 on both sides
4x = 172
Divide 4 on both sides
x = 43
Consider the following statement: Two sets of data with the same mean will also have the same variability. Do you agree or disagree with this statement? Explain.
Answers
The statement is false and same mean can have different variability
What is Mean?The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Mean = Sum of Values / Number of Values
Given data ,
Let the mean of the data be represented as M
Now , The mean is a measure of central tendency that represents the average value of a set of data, but it does not provide information about the variability or spread of the data.
For example, consider the following two sets of data:
Set 1: 1, 2, 3, 4, 5 (mean = 3)
Set 2: 0, 2, 3, 4, 6 (mean = 3)
Both sets have the same mean of 3, but Set 1 has a smaller range (4) compared to Set 2 (6). The range is a measure of variability that represents the difference between the maximum and minimum values in a set of data.
Hence , two sets of data with the same mean can have different variability,

C. x = 45 ; ∠LNM = 135
D. x = 135 ; ∠LNM = 45
Pls dont put nonsense answer thank you
Answers
Linear pair of angles are of 180°. So,
45°+3x = 180°
=> 3x = 180°-45°
=> 3x = 135°
=> x = 135°/3
=> x = 45°
Answer:
Option C: x = 45, ∠LNM = 135
Step-by-step explanation:
Both the angles are supplementary which means they both add up to a straight angle or 180°;
45 + 3x = 180
=> First subtract 45 on each side of "="
3x = 135
=> Now divide both sides of "=" by 3
x = 45Now to find measure of angle LNM, substitute in 45 for x
3x = ∠LNM
3(45) = ∠LNM
135 = ∠LNMHope this helps!
