Which of the following can be used to explain a statement in a geometric proof? Check all that apply.
nikitadnepr [17]

The <em><u>correct answers</u></em> are:

A-theorem ; B-corollary ; C-Postulate ; and E-Definition.

Explanation:

In a proof, we are tasked with proving one statement using other information that has already been proven.

Theorems are statements that have already been proven, and are used to prove other statements.

A postulate is a statement that is assumed to be true, and is used to prove other statements.

A corollary is a direct consequence of a proven fact, and as such, are used to prove other statements.

A definition is an absolute truth, so it can also be used to prove another statement.

El administrador de una cafetería sabe que vende diariamente 50 litros de jugo mixto. Para elaborar este jugo se emplean dos pre
Nina [5.8K]

Answer:

Se necesitan 37.5 litros del preparado que contiene 5% de jugo natural, y 12.5 litros del que contiene 25%.

Step-by-step explanation:

Primero calculamos la cantidad total de jugo natural que se necesita, a partir del volumen de jugo mixto que se quiere vender:

  • 50 L * 10/100 = 5 L

Ahora, que X sean los litros del preparado con jugo de 5%, y que Y sean los litros del preparado con jugo de 25%:

La suma de ambos preparados tiene que ser 50 L:

1.    x + y = 50

La suma del jugo natural tiene que ser 5:

2.   x*5/100 + y*25/100 = 5

Por lo que tenemos <em>un sistema de dos ecuaciones y dos incognitas</em>.

Expresamos x en términos de y:

  • x + y = 50
  • x = 50 - y

Reemplazamos x en la segunda ecuación:

  • (50-y)*5/100 + y*25/100 = 5

Y despejamos <em>y</em>:

  • 2.5 - 0.05y + 0.25y = 5
  • 0.20y = 2.5
  • y = 12.5

Usando ese valor de y, calculamos x:

  • x + 12.5 = 50
  • x = 37.5
