20(base three)-11(base three) . Carry out the operation in binary system​
bija089 [108]

20₃ - 11₃ = 20₃ - 10₃ - 1₃

… = 10₃ - 1₃

… = 2₃

Put another way, we "borrow a 1" from the 3¹ digits place:

20₃ = 1(3)₃ - 11₃ = 2₃

But this is just the number 2 (in base 10), which in base 2 would be 10₂.

Comprás 4 libras de arroz con 10$.¿Cuántos necesitas para 14 libras?​
Fofino [41]

Answer:

Alegría puede comprar 16.667 libras de arroz y 12.5 libras de azúcar con 20 pesos.

Step-by-step explanation:

Sabemos que una libra de arroz cuesta 0.60 pesos, mientras que una de azúcar cuesta 0.80 pesos. Un enfoque posible es determinar cuantas libras de arroz se obtiene por el mismo dinero para adquirir una libra de azúcar a través de una regla de tres simple:

Esto quiere decir que por cada tres libras de azúcar, se compra cuatro libras de arroz. Ahora, la cantidad de alimentos que puede comprar Alegría queda restringida al dinero disponible (20 pesos) y se describe por la siguiente ecuación:

(Ec. 1)

Donde:

- Cantidad de arroz, medida en libras.

- Cantidad de azúcar, medida en libras.

Además, la siguiente ecuación se deriva de la regla de tres del inicio del problema:

(Ec. 2)

Si aplicamos (Ec. 2) en (Ec. 1) y resolvemos la ecuación resultante, tenemos que:

De (Ec. 2) tenemos que la cantidad de arroz es:

En consecuencia, Alegría puede comprar 16.667 libras de arroz y 12.5 libras de azúcar con 20 pesos.
