Un barril de petróleo equivale a 159 litros entonces si un pozo de petróleo produce 374 barriles por minuto. ¿Cuántos litros son? * 10 puntos A) 2.35 B) 4.80 C) 59 466 D) 128 345

Answers

Answer:

374 barriles equivalen a 59466 litros de petróleo.

Step-by-step explanation:

La regla de tres simple es una forma de resolver problemas de proporcionalidad entre tres valores conocidos y un valor desconocido, estableciendo una relación de proporcionalidad entre todos ellos. Es decir, lo que se pretende es encontrar el cuarto término de una proporción conociendo los otros tres. Recuerde que la proporcionalidad es una relación o razón constante entre diferentes magnitudes.

Si la relación entre las magnitudes es directa, es decir, cuando una magnitud aumenta, también lo hace la otra (o cuando una magnitud disminuye, también lo hace la otra), se debe aplicar la regla directa de tres. Para resolver una regla directa de tres, se debe aplicar:

a ⇒ b

c ⇒ x

donde a, b y c son valores conocidos, mientras x es el valor que se desea conocer. Entonces: [tex]x=\frac{c*b}{a}[/tex]

En este caso, la regla de tres se aplica de la siguiente manera: si 1 barril de petróleo equivale a 159 litros, 374 barriles a cuántos litros equivale?

1 barril ⇒ 159 litros

374 barriles ⇒ x litros

[tex]cantidad de litros =\frac{374 barriles*159 litros}{1 barril}[/tex]

cantidad de litros= 59466 litros

374 barriles equivalen a 59466 litros de petróleo.

State the domain for the following relation.{(4, -1), (3, 2), (0, -3), (1, 4)} *
A. {0, 1, 3, 4}
C. {0, 1, 2, 4}
B. {2, 3, 4, 5}
D. {0, 1, 3, 5}

Answers

Answer:

A. {0, 1, 3, 4}

Step-by-step explanation:

For a relation with elements (x, y)

The domain is the set of the x-values, that are the input values.

Here we have the relation:

{(4, -1), (3, 2), (0, -3), (1, 4)}

Here we can see that the inputs are:

4, 3, 0, and 1.

Then the domain is:

{4, 3, 0, 1}

Now let's write this in the correct order:

{0, 1, 3, 4}

The domain of the relation is: {0, 1, 3, 4}

Then the correct option is A.

Coefficient of x = -9.9 ;

Coefficient of x = 75

Coefficient of y = 275

Step-by-step explanation:

Given :

0.8 (2x + x) + 3(7 - 4.1x) = __x + 21

0.8(3x) + 21 - 12.3x = __x + 21

2.4x + 21 - 12.3x = __x + 21

-9.9x + 21 = __x + 21

-9.9
