De qué manera relacionas lo que escuchas o lees en tu vida​
nika2105 [10]

Answer:

La forma en que relaciono lo que escucho o leo en mi vida es a través de la interpretación de la información, es decir, todo aquello que leo o escucho es procesado, evaluado e interpretado conforme a mi experiencia, vivencias, estudios e ideología, lo que me permite obtener una conclusión de la información que percibo.

Así, no considero todo lo que leo y escucho como hechos comprobados, sino que lo someto a un análisis exhaustivo y completo respecto de su validez y sus implicancias respecto de mi persona.

stealth61 [152]

Answer:

The percentage decrease of the shirt's price is 15%.

Step-by-step explanation:

1) divide 36.15 by 30.75

30.75/36.15=0.85

2) Multiply 0.85 by 100 to find the percentage between the original and sale costs of the shirt

0.85(100)= 85%

3) Find the difference between 85% and 100% to find the percentage difference

100%-85%= 15%.

Therefore, the answer is 15%.

Hope this helps!

If person a and person b go fishing and both catch fish. If person a gives half their fish to person b and then they have equal
Alik [6]

Answer:

The number of fishes person b initially has is 0

The number of fishes person a initially has is x, where x is any natural number

Step-by-step explanation:

The given parameters are;

let x represent the number of fish person a catches and let y represent the number of fishes that person b catches, we have;

x - x/2 = y + x/2

2·x - x = 2·y + x

2·x = 2·y + 2·x

∴ y = 0

Therefore;

The number of fishes person b initially has = 0

The number of fishes person a initially has = x, where x is any natural number.
