Step-by-step explanation:

No. It is not possible to reflect a triangle in such a way that the result is quadrilateral with any consecutive sides that are congruent.

Answer:

y = 25.20 m

Step-by-step explanation:

By applying tangent rule in ΔABC,

tan(25)° = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

             = [tex]\frac{y}{BC}[/tex]

BC = [tex]\frac{y}{\text{tan}(25)}[/tex] --------(1)

Now we apply tangent rule in ΔABD,

tan(15)° = [tex]\frac{y}{BC+CD}[/tex]

tan(15)° = [tex]\frac{y}{BC+40}[/tex]

BC + 40 = [tex]\frac{y}{\text{tan}(15)}[/tex]

BC = [tex]\frac{y}{\text{tan}(15)}[/tex] - 40 -------(2)

From equation (1) and (2),

[tex]\frac{y}{\text{tan}(25)}=\frac{y}{\text{tan}(25)}-40[/tex]

[tex]\frac{y}{\text{tan}(25)}-\frac{y}{\text{tan}(25)}=-40[/tex]

[tex]y[\frac{1}{\text{tan}(25)}-\frac{1}{\text{tan}(25)}]=-40[/tex]

y(2.1445 - 3.7321) = -40

1.5876y = 40

y = 25.1953

y ≈ 25.20 m

Therefore, measure of y is 25.20 m.

Answer:

If you know the area of one triangle, then you can multiply it by 2 to get the area of the parallelogram, because the other triangle is congruent.

Answer: 2.25 or 2 1/4 or 9/4

Answer:

Se pueden llenar 4 vasos nuevos de segunda clase con agua de 1 vaso previamente llenado.

Step-by-step explanation:

Spanish

Hay 6 vasos llenos.

Quiere llenar 24 vasos con la misma agua que en los 6 vasos.

El número de vasos nuevos llenados por cada vaso viejo será = 24/6 = 4

Se pueden llenar 4 vasos nuevos de segunda clase con agua de 1 vaso previamente llenado.

English

There are 6 glasses filled.

He wants to fill 24 glasses with the same water as in the 6 glasses.

The  number new glasses  filled for each old glass will be= 24/6= 4

4 new second class glasses can be filled by water from 1  previously filled glass.

Answer:

[tex]\frac{52887}{9900}[/tex]

Step-by-step explanation:

We require 2 equations with the repeating 21 placed after the decimal point.

let x = 5.34212121 ( multiply both sides by 100 and 10000 )

100x = 534.2121... → (1)

10000x = 53421.2121... → (2)

Subtract (1) from (2) thus eliminating the repeating 21

9900x = 52887 ( divide both sides by 9900 )

x = [tex]\frac{52887}{9900}[/tex]

Y = 8000/1000= 8

Y= 8*20

Y= 160

Step-by-step explanation:

A Dilation is defined as  a transformation in which the image and the pre-image have the same shape, but their sizes are different.

When the scale factor is greater than 1, the image obtained after the  dilation is greater than the pre-image and it is an "Enlargement".

When the scale factor is is between 0 and 1,  the image obtained after the  dilation is smaller than the pre-image and it is an "Reduction".

In this case you know that the triangle ABC was dilated by this scale factor:

With the origin as the center of dilation.

Since:

It is a Reduction.

You can identify that the vertices of the triangle ABC are:

So you need to multiply the coordinates of each vertex  of the triangle ABC by , in order to get the coordinates of the triangle A'B'C. Then, you get:

Answer:

950, 1121.00, 1322.78, 1,560.88, 1,841.84

Step-by-step explanation:

Calculation to determine the sequences that describes his increasing monthly balance

Based on the information given in order for us to determine the sequence we have to multiply the amount owes by the interest rate and then add back the answer you got to the previous amount you multiplied the interest rate to.

First sequence will be the amount he owes on a credit which is $950

Second sequence

950 * .018 = 171.00

950 + 171.00 = 1121.00

Third sequence

1121.00 * .018 = 201.78

1121.00 + 201.78 = 1322.78

Fourth sequence

1322.78*0.18=238.10

1322.78+238.10=1,560.88

Last sequence

1,560.88*0.18=280.96

1,560.88+280.96=1,841.84

Therefore the sequences that describes his increasing monthly balance are:

950, 1121.00, 1322.78, 1,560.88, 1,841.84

Answer:

1.5

Step-by-step explanation:

To find out the gradient (or the slope), we can use the formula

Gradient = (y2-y1)/(x2-x1), where (x1,y1) and (x2,y2) are any two points lying on the line.

Looking at the graph, we can take any two points and simply plug the coordinates in the equation. For instance, take (0,-2) and (2,1)

Therefore we get the gradient as (1- -2)/(2-0) = 3/2 or 1.5.

Feel free to ask any doubts you may have.

Answer:

x = 5, y = 4

Step-by-step explanation:

Solve for one variable. x will be simpler using the second equation.

3x = 15

Divide by 3.

x = 5.

Now put that into the other equation.

4x + 5y = 40

Substitute variable.

4(5) + 5y = 40

20 + 5y = 40

Subtract 20 from both sides.

5y = 20

Divide by 5.

y = 4.
