Encuentre el resultado de la diferencia de las fracciones: 9 /12 - 2/3=​
Veronika [31]

Responder:

1/12

Explicación paso a paso:

Entonces multiplicamos 9 por 3 y obtenemos 27.

Luego multiplicamos 2 por 12 y obtenemos 24.

A continuación, le damos a ambos términos nuevos denominadores: 12 × 3 = 36.

Así que ahora nuestras fracciones se ven así:

27

36

-

24

36

Paso 2

Dado que nuestros denominadores coinciden, podemos restar los numeradores.

27 - 24 = 3

Entonces la respuesta es:

3

36

Paso 3

Por último, necesitamos simplificar la fracción, si es posible. ¿Se puede reducir a una fracción más simple?

Para averiguarlo, intentamos dividirlo por 2 ...

¡No! Así que ahora probamos con el siguiente número primo mayor, 3 ...

¿Son tanto el numerador como el denominador divisibles por 3? ¡Sí! Entonces lo reducimos:

3

36

÷ 3 =

<u>1/12 </u>

Antonio is a biologist studying life in a pond. He needs to know how deep the water is. He notices a water lily sticking straigh
quester [9]
For this problem we can represent the situation as a rectangle triangle.
 x: depth of water.
 40: Base. "Antonio pulls the lily to one side, keeping the stem straight, until the blossom touches the water at a spot"
 x + 8: Hypotenuse. "He notices water lily sticking straight up from the water, whose blossom is 8 cm above the water's surface." Antonio pulls the lily to one side, keeping the stem straight, until the blossom touches the water at a spot".
 By the Pythagorean theorem we have:
 x ^ 2 + 40 ^ 2 = (x + 8) ^ 2
 Clearing x:
 x ^ 2 + 1600 = x ^ 2 + 16x + 64
 x ^ 2 - x ^ 2 = 16x + 64 - 1600
 0 = 16x -1536
 1536 = 16x
 1536/16 = x
 x = 96
 answer:
 1) x ^ 2 + 40 ^ 2 = (x + 8) ^ 2
 2) the depth of the water is
 x = 96
