En mi familia tres primos cumplimos años el mismo día y la abuela quiere regalarnos dinero a los tres para que nos compremos lo

Dafna1 [17]

Answer:

Tu recibiste = $1714,3

Reiner recibió = $857,1

Julio recibió = $3428,6

Step-by-step explanation:

Podemos encontrar el dinero que recibieron todos mediante la siguiente expresión:

$A + R + C = 6000$

Dado que A recibió 2 veces más que el dinero que Reiner y C recibió 4 veces lo que recibió Reiner, entonces:

$2R + R + 4R = 6000$

$R = \frac{6000}{7} = 857,1$

Ahora, podemos encontar cuanto recbieron los otros dos primos:

$A = 2R = 2*\frac{6000}{7} = \frac{12000}{7} = 1714,3$

$C = 4R = 4*\frac{6000}{7} = \frac{24000}{7} = 3428,6$

Por lo tanto, tu recibiste $1714,3, Reiner recibió $857,1 y Julio recibió $3428,6.

Espero que te sea de utilidad!

According to U.S. postal regulations, the girth plus the length of a parcel sent by mail may not exceed 108 inches, where by "gi

Answer:

11,664 inches³

Step-by-step explanation:

Let 'S' be the length of the side of the square base and 'H' be height of the parcel.

The U.S postal regulations specify that:

$4S +H = 108\\H=108-4S$

The volume of the parcel is given by:

$V=H*S^2\\V=(108-4S)*S^2\\V=108S^2-4S^3$

The value of 'S' for which the derivate of the volume function equals zero yields the maximum volume:

$\frac{dV(S)}{dS}= 216S-12S^2=0\\\frac{216S-12S^2}{S}=\frac{0}{S} \\216 - 12S =0\\S=18\ inches$

Solving for 'H':

$H=108-4S = 108-(4*18)\\H= 36\ inches$

The maximum volume is:

$V_{max} = 36*18^2\\V_{max} = 11,664\ inches^3$
