Habiendo salido el 84% de los alumnos de un colegio, permanecen en el mismo 20 alumnos. ¿Cuántos alumnos salieron del colegio?

Answers

Answer 1

Answer:

105 students

Step-by-step explanation:

The computation of the number of students left the school is given below:

Let us assume the total students be  x  and 100%

Left percentage = 84%

Remaining percentage = 100% - 84% = 16%

Now according to the question

16% of x = 20

0.16x = 20

x = 20 ÷ 0.16

x = 125

Total students 125

Those who left is

= 84% of 125

= 105 students

The upper-left coordinates on a rectangle are (-6,0)(−6,0)left parenthesis, minus, 6, comma, 0, right parenthesis, and the upper-right coordinates are (-4,0)(−4,0)left parenthesis, minus, 4, comma, 0, right parenthesis. The rectangle has an area of 121212 square units. Draw the rectangle on the coordinate plane below.

Answers

Answer:

See attachment for rectangle

Step-by-step explanation:

Given

[tex]A = (-6,0)[/tex]

[tex]B = (-4,0)[/tex]

[tex]Area = 12[/tex]

Required

Draw the rectangle

First, we calculate the distance between A and B using distance formula;

[tex]AB = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

So, we have:

[tex]AB = \sqrt{(-6 - -4)^2 + (0- 0)^2}[/tex]

[tex]AB = \sqrt{(-2)^2 + (0)^2}[/tex]

[tex]AB = \sqrt{4 + 0}[/tex]

[tex]AB = \sqrt{4}[/tex]

[tex]AB = 2[/tex]

The above represents the length of the triangle.

Next, calculate the width using:

[tex]Length * Width = Area[/tex]

[tex]2* Width = 12[/tex]

Divide both sides by 2

[tex]Width = 6[/tex]

This implies that, the width of the rectangle is 6 units.

We have:

[tex]A = (-6,0)[/tex]

[tex]B = (-4,0)[/tex]

Since A and B are at the upper left and right, then the ther two points are below.

6 units below each of the above point are:

[tex]C = (-6,0-6)\\[/tex] => [tex]C = (-6,-6)[/tex]

[tex]D = (-4,0-6)[/tex] => [tex]D = (-4,-6)[/tex]

Hence, the points of the rectangle are:

[tex]A = (-6,0)[/tex]

[tex]B = (-4,0)[/tex]

[tex]C = (-6,-6)[/tex]

[tex]D = (-4,-6)[/tex]

Can you guys please answer this is really important

Answers

Answer:

B) BC'= 8, m A'= 28°

Step-by-step explanation:

When dilating a figure, it increases its size or decreases. In this case, as it is dilating by a factor of 1/2, you can assume it decreases.

To find the value of the new figure, A'B'C', you have to multiply the factor times the lengths of the triangle, or, the only one they are asking for in this case, the length BC':

BC' = BC×1/2BC' = 16×1/2BC' = 8

The angles, otherwise, do not change. When figures are dilated, they are similar. The properties of similar figures are that they have congruent angles, therefore, the same angles. They do not have any effect caused by the factor, so m A' stays at 28°.

What is the area of this regular pentagon that has been divided into five congruent triangles?

48 [tex]cm^{2}[/tex]

120 [tex]cm^{2}[/tex]

100 [tex]cm^{2}[/tex]

24 [tex]cm^{2}[/tex]

Answers

Answer:

120 cm^2.

Step-by-step explanation:

The area of one triangle = 1/2 * base * height

= 1/2 * 8 * 6

= 1/2 * 48

= 24 cm^2

So area of the pentagon = 5 * 24

= 120 cm^2.

0, 5, 5, 10, 10, 10, 15, 15, 15, 20, 20, 20, 25, 25, 30.

Because there are 15 values in the data set, the first quartile is the 4th value, which is 10, and the third quartile is the 12th value, which is 20.
