Mathematics

Answer:

Un número racional es un número que puede expresarse como una fracción p / q donde p y q son enteros y q! = 0. Se dice que un número racional p / q tiene numerador p y denominador q. Los números que no son racionales se llaman números irracionales. La línea real consiste en la unión de los números racionales e irracionales. El conjunto de números racionales es de medida cero en la línea real, por lo que es "pequeño" en comparación con los irracionales y el continuo.

El conjunto de todos los números racionales se denomina "racionales" y forma un campo que se denota como Q. Aquí, el símbolo Q deriva de la palabra alemana Cociente, que se puede traducir como "cociente", y apareció por primera vez en Bourbaki. Algèbre (reimpreso como Bourbaki 1998, p. 671).

Cualquier número racional es trivialmente también un número algebraico.

Los ejemplos de números racionales incluyen -7, 0, 1, 1/2, 22/7, 12345/67, y así sucesivamente. Las secuencias de Farey proporcionan una forma de enumerar sistemáticamente todos los números racionales.

El conjunto de números racionales se denota Racionales en Wolfram Language, y se puede probar un número x para ver si es racional usando el comando Elemento [x, Racionales].

Las operaciones algebraicas elementales para combinar números racionales son exactamente las mismas que para combinar fracciones.

Siempre es posible encontrar otro número racional entre dos miembros del conjunto de racionales. Por lo tanto, más bien contra intuitivamente, los números racionales son un conjunto continuo, pero al mismo tiempo contables.

An elementary school buys tickets for a field trip to the zoo. The number of children going on the field trip is 2 times the num
ioda
To answer the question, let x be the number of adults going to the zoo and 2x be the number of children. The total amount gained from the ticket sales should be,
                             1650 = 6x + 4(2x)
The values of x is equal to 117.86. Therefore, the school bought approximately 118 tickets for adults and 236 for children.

Dennis_Churaev [7]

Answer:

D(h) = 55h - 2000

1670 m

Step-by-step explanation:

Given :

Starting elevation, D = - 2000 m (2000 m below sea level)

Rate, h = 55 m per hour.

The slope - intercept relation :

y = mx + c

m = slope = rate of change

c = intercept

In the scenario given :

-2000 = intercept

55 = rate of change

D(h) = 55h - 2000

After 6 hours :

D(6) = 55(6) - 2000

D(6) = - 1670 m
