Durante la posguerra, Estados Unidos y Europa iniciaron una serie de negociaciones. ¿Cuál fue uno de los principales resultados de esa negociación?

Answers

Answer:

Dos resultados: Plan Marshall (1.947 - 1.952): Reconstrucción económica de Europa, la Organización del Tratado del Atlántico Norte (1.949 - ): Esquema defensivo de Europa frente a una potencial invasión soviética.

Explanation:

En esas negociaciones se establecieron dos iniciativas que marcarían el desarrollo de la Europa Occidental hasta la fecha, el primer resultado fue el desarrollo del Plan Marshall, un plan de reconstrucción de los países de Europa Occidental con dineros, empresas, bienes, servicios y especialistas estadounidenses que permitió a los gobiernos de aquellos evitar el triunfo de partidos comunistas, especialmente en Italia y Francia, además permitió que Europa recuperara sus niveles de producción de antes de la Segunda Guerra Mundial a finales de los años cincuenta y se reconstruyera plenamente a finales de los años sesenta.

Sin el Plan Marshall, no hubiera sido posible los Treinta Gloriosos en Francia (1.945 - 1.973), la Wirtschaftswunder en la Alemania Occidental (1.949 - 1.964) o el Miracolo economico en Italia (1.957 - 1.968). Tampoco habría sido posible el desarrollo de la Comunidad Económica Europea, antecesora de la actual Unión Europea.

Otra consecuencia, fue el establecimiento de una alianza de fuerzas militares con centro en unidades destacadas de las Fuerzas Armadas de los Estados Unidos en Europa, bajo el nombre de la Organización del Tratado del Atlántico Norte (O.T.A.N.) en 1.949, diseñada inicialmente para contener y combatir una invasión soviética a los países de Europa Occidental.

For the line segment whose endpoints are A(0,0) and B(4,3), find the X coordinate for the point located 2/3 the distance from a to b.

Answers

Answer:

2.7

Explanation:

Short answer: took the test

Actual explanation: Finding the coordinate means that we need to find the x distance first between the two points. So, the coordinates are A (0, 0) and B (4, 3).  

- the x distance: 0 to 4, which is 4 units.

Using the 4 units and the fraction, 2/3 because we want to find it 2/3 the distance a-b, we set it up like this

-2/3 * 4/1 (4/1 comes from the x-distance, which is 4 units) and get 8/3 (by multiplying across) which is 2.666,

and we round it to get 2.7, which is the final answer.

they are only asking for the x-distance, which is why we only solved for the x distance.

hope this helps :)
~addison~

Two unique points on a line define the boundaries of a line segment. A line segment is sometimes referred to as a section of a line that links two places.

2.7 : In order to calculate the coordinate, we must first determine the x distance between the two points. So, A (0, 0) and B are the coordinates (4, 3).

- the x distance, which is 4 units from 0 to 4.

This is how we set it up using the 4 units and the fraction 2/3 to get the distance between a and b.

-2/3 * 4/1 (4/1 is the result of the x-distance, which is 4 units), which produces 8/3 (by multiplication across), which is 2.666,

2.7 is the result after rounding, which completes the equation.

We just provided a solution for the x distance since that is all they asked for.

What is an example of a line segment?
