Answer:
D
Step-by-step explanation:
hard to explain but when you rotate 180, you can imagine that a straight line with the center of rotation as the midpoint can be drawn between the image and preimage. you want a mapped to c and you want d mapped to b. having it rotate 180 with the center of rotation being the center of the parallelogram allows you to make those imaginary lines between a and c and d and b. hope this helps

Classify the triangle based on the side lengths 7. 15 and 21
Triangle based on the side lengths 7. 15 and 21 is Obtuse triangle.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
The sides of triangle are 7, 15 and 21.
Let the largest angle be θ.
cosθ=7²+15²-21²/2×7×15
=-167/210
Since arc cos(-167/210)=142.68 degrees.
θ=142.68 degrees.
Which means θ>90 degrees.
So its a obtuse triangle.
7+15=22>21
21-7=14<15
So those angles can make a obtuse triangle.
Hence, triangle based on the side lengths 7. 15 and 21 is Obtuse triangle.

Miguel glues a ribbon border around the edges of a 5-inch by 8-inch picture to create a frame. What is the total length of ribbon Miguel uses?
[tex]\qquad[/tex] ☀️So First – we have to find the perimeter of the frame on which the glue is applied and the length of the ribbon used by Miguel. The perimeter of the frame is the total length of ribbon Miguel uses.
Length of the frame is = 5 inchBreadth of the frame is = 8 inch[tex]\qquad[/tex]____________________
According to the question:-
[tex]\qquad[/tex][tex] \pink{\bf\longrightarrow Perimeter _{(The \:frame) }= The\: total\: length\: of \:ribbon}[/tex]
The frame is in the rectangular shape, as its length and breadth are different . As we know– Perimeter of the rectangle = 2 ( length + breadth ).[tex]\qquad[/tex][tex] \purple{\bf \longrightarrow Perimeter _{(The \:frame) } = 2 ( length\: of\: the \:frame + breadth \:of \:the\: frame )}[/tex]
[tex]\qquad[/tex][tex] \sf \longrightarrow Perimeter _{(The\: frame) } = 2 ( 5 + 8 ) [/tex]
[tex]\qquad[/tex][tex] \sf \longrightarrow Perimeter _{(The \:frame) }= 2 ( 5 ) + 2 ( 8 ) [/tex]

[tex]\qquad[/tex][tex] \purple{\bf \longrightarrow Perimeter _{(The \:frame) }= 26\: inch} [/tex]
Henceforth, perimeter of the frame is 26 inch.Therefore,
Perimeter of the frame = The total length of ribbon.So, The total length of ribbon = 26 inch.[tex]\qquad[/tex]____________________

-11 + 9b² = 25
If you can help me I will be very grateful!
Answer:
b=4
Step-by-step explanation:
-11+9b^2=25
add 11 to both sides
9b^2=36
divide both sides by 9
b^2=4
take the square root of both sides
b=4

The price of petrol increased by 8% to Rs 540 per litre. Find the old price.
Answer:
The original price is Rs. 50
Step-by-step explanation:
Let the original price be Rs.x
x+8% of x=54
x+(8/100)*x=54
x+8x/100=54
(100x+8x)/100=54
108x/100=54
x=54* 100/108
x=50.
The original price is Rs. 50
Answer:
Rs 500 per literStep-by-step explanation:
Let the initial price be x.
We have:
x + 8% of x = 540Rewrite it as below and solve for x:
x + 0.08x = 5401.08x = 540x = 540/1.08x = 500PLEASE NO LINKS AND NO NEGATIVITY

We cross multiply:
q(t + 3) = 2 - 4t
qt + 3q = 2 - 4t
qt + 4t = 2 - 3q
t(q + 4) = 2 - 3q

Examine the diagram, where BD is tangent to circle M at point D, and BA is secant to the same circle at points E and A.
Answer:
19 = x
Step-by-step explanation:
The square of the tangent segment = The product of (whole secant segment) (the outside part of the secant segment)
BD²= (BA)(BE)
8² = (4 + x - 7) (4) BA = BE + EB
8² = (x - 3)(4)
64 = 4x - 12
64 + 12 = 4x
76 = 4x
19 = x

A) Total number of old plans = 3500 + 4700 = 8200
In the new month, the unlimited plans increased by 55%, which adds
0.55 • 3500 = 1925
unlimited plans, while the limited plans decreased by 25%, which subtracts
0.25 • 4700 = 1175
limited plans. Then
Total number of new plans = (3500 + 1925) + (4700 - 1175) = 8950
which corresponds to a percent change of
(8950 - 8200)/8200 ≈ 0.0915 = 9.15%
That is, percent change is given by
(new value - old value) / (old value)
B) The percent change is positive, so it's a percent increase.
On a coordinate plane, triangle R S T has points (negative 5, 6), (3, 4), and (negative 2, 2). Which expression can be used to find the area of triangle RST? (8 â™ 4) - One-half (10 12 16) (8 â™ 4) - (10 12 16) (8 â™ 4) - One-half (5 6 8) (8 â™ 4) - (5 - 6 - 8).
The area of a triangle is the amount of space on the triangle
The expression that represents the area of the triangle is [tex]A = \frac 12|-5(2 -4) +3(2 -6) -2(4 -6)|[/tex]
The coordinates of the triangle are given as:
[tex]R = (-5,6)[/tex]
[tex]S = (3,4)[/tex]
[tex]T = (-2,2)[/tex]
The area (A) of a triangle from its coordinates or vertices are:
[tex]A = \frac 12|x_1(y_3 -y_2) +x_2(y_3 -y_1) + x_3(y_2 -y_1)|[/tex]
Substitute values for x's and y's
[tex]A = \frac 12|-5(2 -4) +3(2 -6) -2(4 -6)|[/tex]
Hence, the expression that represents the area of the triangle is [tex]A = \frac 12|-5(2 -4) +3(2 -6) -2(4 -6)|[/tex]

What is a cuboid?A closed three-dimensional geometric shape called a cuboid is surrounded by six rectangular plane sections.
The given figure is a cuboid with dimensions (2x + 2), (x + 1), and (x + 3).
The volume of the cuboid is the multiplication of its dimension, therefore, the volume of the cuboid is:
V = (2x +2)(x + 1)(x + 3)
V = (2x² + 2x +2x + 2)(x + 3)
V = (2x² + 4x + 2)(x + 3)
V = 2x³ + 6x² + 4x² + 12x + 2x + 6
V = 2x³ + 10x² + 14x + 6
