Una empresa fabrica dos modelos de DVD: el modelo A y el modelo B. Se dispone de 50 kilogramos de caucho y de 80 horas de mano d
alexandr1967 [171]

Answer:

¿Cuántos DVD de cada tipo debe fabricar y vender para que la utilidad sea máxima?

Se debe fabricar y vender 20 DVD del modelo A y 30 DVD del modelo B. La utilidad máxima es de de S/. 1 800

Step-by-step explanation:

x : Número de DVD del modelo A

y : Número de DVD del modelo B.

                               MODELO A MODELO B TOTAL

Cantidad de caucho                  1x 1x                 50 kg.

Horas de mano de obra           1x 2x                 80 horas

U : Utilidad mensual.

La función objetivo, que se debe maximizar, es:

U=30   + 40y

x+ y \leq 50\\  

x + 2y \leq 80

x\geq 0

y\geq 0

Las coordenadas de los vértices de la región factibles son:

A (0, 0) B (50, 0) C (20, 30) D(0, 40)

Entonces, se evalúa la función objetivo en cada punto:

U (0, 0) = 30 (0) + 40 (0) = 0

U (50, 0) = 30 (50) + 40(0) = 1500

U (90, 0) = 30 (20) + 40 (30) = 1800

U (0, 40) = 30 (0) + 40 (40) =1600

Por consiguiente U tiene un valor máximo en C , en donde: x =20 ,  y = 30 .

Se debe fabricar y vender 20 DVD del modelo A y 30 DVD del modelo B. La utilidad máxima es de de S/. 1 800.

En una tienda venden pepitas de chocolate y nueces. 2 libras de pepitas de chocolate y libras de nueces cuestan $20 en total. 8
SVETLANKA909090 [29]

Responder:

$ 2.5 y $ 3

Explicación paso a paso:

Paso uno:

datos dados

Sea xey el costo por libra de chispas de chocolate y nueces, respectivamente

por lo tanto

2x + 5y = 20 ------ 1

y

8x + 3y = 29 ------ 2

resolviendo 1 y 2 simultáneamente tenemos

2x + 5y = 20 (multiplicar la ecuación por 4)

8x + 20y = 80 ------------- 3

restar eqn 2 de 3

8x + 20y = 80 ------------- 3

8x + 3y = 29 ----------------- 2

0 + 17 años = 51

divide ambos lados por 17

y = 51/17

y = 3

El costo de las nueces por libra = $ 3

poner y = 3 en 8x + 3y = 29 ------ 2

8x + 3 (3) = 29 ------ 2

8x + 9 = 29

8x = 29-9

8x = 20

divide ambos lados entre 8

x = 20/8

x = 2,5

El costo del chocolate por libra = $ 2.5

Alisiya [41]

\bf \textit{equation of a circle}\\\\ (x- h)^2+(y- k)^2= r^2 \qquad center~~(\stackrel{4}{ h},\stackrel{1}{ k})\qquad \qquad radius=\stackrel{2}{ r} \\\\\\ (x-4)^2+(y-1)^2=2^2\implies (x-4)^2+(y-1)^2=4
