Which composition of similarity transformations maps polygon ABCD to polygon A’B’C’D
Answers
The correct answer is option B.
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
A dilation with a scale factor less than 1 and then a reflection
To this point, we've encountered four kinds of symmetry:
Reflection, rotation, translation, and glide-reflection.
These symmetries are rigid motions as a result of they move a figure whereas conserving its size and shape.
All transformations are isometric. Dilation may be a non-isometric transformation. A stretch isn't a similarity transformation.
Dilations, rotations, reflections, and translations are all similar transformations. Since rotation, reflection, and translation are rigid motions, they preserve each size and shape, whereas dilation solely ensures that the form is preserved.
the multiplier is outlined as the magnitude relation of the dimensions of the new image to the size of the previous image.
the middle of dilation may be a mounted purpose within the plane.
supported the dimensions issue and therefore the centre of dilation, the dilation transformation is defined.

Answer:
Hey there!
Unless the smaller object was rotated 360° (in which case the rotation wouldn't have to be mentioned), you can see that all of the lines are still in the same place and that it wasn't rotated at all. This eliminated any answer option that mentions a rotation, which is A and C.
Also, if you count the units of one of the straight lines – for example, line AB and A'B' – you can see that the smaller object is four times smaller than the larger object. In the case of line AB and A'B', line AB is 8 units long and A'B' is 2 units long. This means that the scale factor is .
Lastly, the smaller object was moved from its initial location, which would be in the center of the larger object if it wasn't moved after being scaled down.
The answer will be B, "a dilation with a scale factor of and then a translation."

The ratio of the number of minutes Arnold lifted weights to the total number of minutes is 1:2 or 1 / 2.
What is ratio?
An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.
Given:
Arnold full workout consist of 10 minutes of warm-up exercises, 25 minutes of lifting weights, and 15 minutes on the treadmill,
Calculate the total time of the work-out as shown below,
Total time of workout = Time of warm-up exercises + Time of lifting weights + Time on the treadmill
Total time of workout = 10 + 25 + 15
Total time of workout = 50 minutes,
Calculate the ratio of the number of minutes he lifted weights to the total number of minutes as shown below,
The ratio of the number of minutes he lifted weights to the total number of minutes = Time of lifting weights / Total time of workout
The ratio of the number of minutes he lifted weights to the total number of minutes = 25 / 50
The ratio of the number of minutes he lifted weights to the total number of minutes = 1 / 2.

We can write everything down based on x.
Longer piece = 2x + 1
Longer piece + Shorter piece = 16
x + 2x + 1 = 16
Collect Like Terms
3x + 1 = 16
Subtract 1 from both sides
3x = 15
Divide both sides by 3
x = 5
Longer piece = 2x + 1
Longer piece = 2(5) + 1
Longer piece = 10 + 1
Longer piece = 11
11 + 5 = 16
Longer piece = 11 ft.
Shorter piece = 5 ft.
Answer: long: 11 short 5

The cost of the milk is in 1950s.
Further explanation:
The price of milk in 2013 was around a gallon.
And it is given that this was eight times as much as one can would have probably paid for a gallon of milk in the 1950s.
It is given that the price of milk in 2013 is a gallon.
Assume the price of milk in 1950 be a gallon.
Now, given that 8 times of is the price of milk in 2013.
Therefore, is the price of milk in 2013 and also
is the price of milk in 2013.
Equating and
equal as both are the price of milk in 2013 as,
Here, x is the price of milk in 1950.
Therefore, the cost of the milk is in 1950s.
