Answer:

[tex] = (3209) - (1893) \\ = 1.32 \times {10}^{3} \\ = 1320[/tex]

[tex] \small{ \star{ \underline{ \blue{becker}}}}[/tex]

Answer:

1320

Step-by-step explanation:

round off

3209 ≈ 3210

1893 ≈ 1890

estimated difference = 3210 - 1890 = 1320

un cuadrilátero es un polígono con cuatro aristas y cuatro vértices

Los elementos o características de un cuadrilátero son los siguientes:

4 vértices: puntos de intersección de los lados que conforman el cuadrilátero.

4 lados: segmentos que unen los vértices contiguos.

2 diagonales: segmentos cuyos extremos son dos vértices no contiguos.

4 ángulos interiores: el determinado por dos lados contiguos.

4 ángulos exteriores: el determinado por la prolongación de uno de los lados sobre un vértice y el contiguo en el mismo vértice.

Un incentro, centro de la circunferencia inscrita.

La suma de sus ángulos interiores es igual a 360º

Los cuadriláteros se clasifican según el paralelismo de sus lados, sus longitudes y sus ángulos interiores:

Paralelogramo: sus lados opuestos son paralelos.

Cuadrado: todos sus lados son iguales, todos sus ángulos interiores son rectos, sus diagonales son iguales y perpendiculares entre sí, tiene una circunferencia inscritas y otra circunscrita, además todos los cuadrados son semejantes entre sí .

Rombo: todos sus lados son iguales, cada par de ángulos agudos y obtusos son opuestos, sus diagonales son distintas y perpendiculares entre sí, son bisectrices, tiene una circunferencia inscrita.

Rectángulo: sus lados opuestos son iguales dos a dos y los paralelos, todos sus ángulos interiores son rectos, sus dos diagonales son iguales pero no son perpendiculares entre sí y tiene una circunferencia circunscrita.

Romboide: sus lados opuestos son iguales dos a dos, cada par de ángulos agudos y obtusos son opuestos, sus dos diagonales son de distinta longitud y no son perpendiculares entre sí.

Trapecio: En geometría, se llama trapecio a un cuadrilátero que tiene dos lados no consecutivos paralelos llamados bases del trapecio, y el segmento perpendicular entre las dos bases y su propia longitud son llamadas altura del trapecio

Trapezoide: En geometría euclídea plana, un trapezoide es un cuadrilátero convexo sin lados paralelos.

Answer:

45.5 u²

Step-by-step explanation:

first we need to find the base of the triangle so we subtract 8-5=3, now since its 2 triangles we divide by 2 and we get 1.5 for each base of the triangles

area for a triangle: A=bh/2

A=(1.5)(7)/2

since its 2 triangles then multiply by 2

A= 10.5 u²

area for a rectangle: A=bh

A=(7)(5)

A= 35 u²

35+10.5 = 45.5 u²

Answer: x > 20

Step-by-step explanation:

9 - x < - 11

In this scenario, we've to collect like terms in order to.wolve for x. This will be:

9 - x < - 11

- x < - 11 - 9

- x < - 20

Divide both side by -1

-x/-1 < -20/-1

When we divide by a coefficient with minus sign, the sign changes too from less than to greater than

-x/-1 < -20/-1

x > 20

Answer:

225

Step-by-step explanation:

Some other numbers that would work are:

255, 525, 555

Answer:

252, 522, 222, and 552

Step-by-step explanation:

For a number to be divisible by 6, it needs to be divisible by both 2 and 3. For a number to be divisible by 2, it needs to end in an even number, and the only even number we can use is 2.

So far our number is _ _ 2.

For a number to be divisible by three, its digits have to add up to a multiple of three. As of now we need to fill in the hundreds and tens place, and there are 4 combinations to check: 2, 5; 5, 2; 2, 2; and 5, 5.

Case #1: 2, 5

We are checking to see if the number 252 is divisible by six.

2 + 5 + 2 = 9

Since the numbers add up to a multiple of 3, 252 is divisible by 6.

Case #2: 5, 2

We are checking to see if the number 522 is divisible by six.

5 + 2 + 2 = 9

Since the numbers add up to a multiple of 3, 522 is divisible by 6.

Case #3: 2, 2

We are checking to see if the number 222 is divisible by six.

2 + 2 + 2 = 6

Since the numbers add up to a multiple of 3, 222 is divisible by 6.

Case #4: 5, 5

We are checking to see if the number 552 is divisible by six.

5 + 5 + 2 = 12

Since the numbers add up to a multiple of 3, 552 is divisible by 6.

Answer:

x = 21.52

Step-by-step explanation:

Given:

hypotenuse (That has to be found out)

Side adjacent to the given angle

and an angle,

Hence we can say that Cos ratio would be used;

Cos(28) = 19 / x

x = 19 / Cos(28)

x = 21.52

Answer:

  (x, y) = (4, 5)

Step-by-step explanation:

We notice that the coefficients of y are opposites, so we can eliminate y by adding the two equations together.

  (4x -3y) +(x +3y) = (1) +(19)

  5x = 20 . . . . . . simplify

  x = 4 . . . . . . . . .divide by 5

Substituting into the second equation gives ...

  4 +3y = 19

  3y = 15 . . . . . . . subtract 4

  y = 5 . . . . . . . . . divide by 3

The solution is (x, y) = (4, 5).

Answer: circle

Step-by-step explanation:

The shape of the cross-section is formed when a cylinder intersects the plane is a circle option (A) is correct.

In geometry, it is defined as the three-dimensional shape having two circular shapes at a distance called the height of the cylinder.

We know the volume of the cylinder is given by:

[tex]\rm V = \pi r^2 h[/tex]

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

As we know, the circle is a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

As we can see in the picture the cylinder is cut by a plane that is parallel to the base of the cylinder.

The base of the cylinder is a circle.

the shape of the cross-section is formed when a cylinder intersects a

the plane is a circle.

Thus, the shape of the cross-section is formed when a cylinder intersects the plane is a circle option (A) is correct.

so in the union formula: AUB=A+B-A∩B

A∩B=0
