Como aser conjuntos​
Kryger [21]

No entiendo cuál es la pregunta, ¿qué son los conjuntos? si es la respuesta es ........

En matemáticas, un conjunto es una colección de elementos. Los elementos que componen un conjunto pueden ser cualquier tipo de objeto matemático: números, símbolos, puntos en el espacio, líneas, otras formas geométricas, variables o incluso otros conjuntos. El conjunto sin elemento es el conjunto vacío; un conjunto con un solo elemento es un singleton.

Triangle ABCTriangle ABC ​is transformed with the center of dilation at the origin. Pre-image: △ABC with vertices A(−5, −4), B(−
harkovskaia [24]

Pre Image  having vertices : △ABC with vertices A(−5, −4), B(−7, 3), C(3, −2)

Image having vertices : △A′B′C′ with vertices A′(−3.75, −3), B′(−5.25, 2.25), C′(2.25, −1.5).

As, Size of Preimage > Size of image

So, 0<Dilation Factor <1

When a triangle is dilated , the preimage and image are similar to each other .

Scale factor can be get through by finding the ratio of any of corresponding sides of triangle.

\frac{A'B'}{AB}=\frac{\sqrt{2.25 +27.5625}}{\sqrt{4+49}}=\sqrt{\frac{29.8125}{53}}=\sqrt{0.5625}=0.75=\frac{3}{4}

So, Scale Factor of Dilation = \frac{3}{4}=0.75

What times what equals 52 in mixed fractions
Softa [21]
To do this, we calculated all possible solutions to this problem:

what x what = 52

Note that "what" and "what" in the above problem could be the same number or different numbers.

Below is a list of all the different ways that what times what equals 52.

<span>1 times 52 equals 52

2 times 26 equals 52

4 times 13 equals 52

13 times 4 equals 52

26 times 2 equals 52

52 times 1 equals 52
