18 cajas de manzanas y peras fueron llevadas a la escuela. Las peras trajeron 210 kg en 6 cajas. ¿Cuántos kilos de manzanas fuer

Katyanochek1 [597]

Answer:

504 kilos de manzanas fueron llevados a la escuela.

Step-by-step explanation:

Sean $x$ , $y$ la cantidad de cajas de manzanas y peras, respectivamente. De acuerdo con el enunciado, tenemos el siguiente sistema de ecuaciones:

Total de cajas

$x+y = 18$ (1)

Masa de cada caja de peras

$y\cdot m_{P} = 210$ (2)

$y = 6$ (3)

Masa de caja de manzanas

$m_{M} = m_{P}+7$ (4)

De (2) en (3), tenemos que la masa de cada caja de peras es:

$m_{P} = 35\,kg$

Por (4), encontramos que la masa de cada caja de manzanas es:

$m_{M} = 35\,kg+7\,kg$

$m_{M} = 42\,kg$

Finalmente, de (1) tenemos la cantidad de cajas de manzana:

$x = 18-y$

$x = 12$

La cantidad de kilos de manzanas llevada a la escuela se obtiene al multiplicar la cantidad de cajas de manzana por la masa de cada caja:

$M = (12)\cdot (42\,kg)$

$M = 504\,kg$

504 kilos de manzanas fueron llevados a la escuela.

If [infinity] cn8n n = 0 is convergent, can we conclude that each of the following series is convergent? (a) [infinity] cn(−3)n

pashok25 [27]

Answer:

a) we know that this is convergent.

b) we know that this might not converge.

Step-by-step explanation:

Given the $\sum^\infty_{n=0}C_n8^n$ is convergent

Therefore,

(a) $\sum^\infty_{n=0}C_n(-3)^n$ The power series $\sum C_nx^n$ has radius of convergence at least as big as 8. So we definitely know it converges for all x satisfying -8<x≤8. In particular for x = -3
