Answer:   65°

<u>Step-by-step explanation:</u>

E=w(t_f-t_o)\\\\E: 10\ cubic\ feet\times \dfrac{1000\ BTU}{1\ cubic\ foot}\times \ 60\%\quad \rightarrow \quad E=6000\ BTU\\\\\\w:50\ gallons\times \dfrac{8\ pounds}{1\ gallon}\quad \rightarrow \quad w=400\ pounds\\\\\\\\E=w(t_f-t_o)\\\\6000=400(t_f-50)\\\\\dfrac{6000}{400}=\dfrac{400(t_f-50)}{400}\\\\.\quad 15=t_f-50\\\\\\.\quad 15=t_f-50\\.\ \underline{+50}\quad \underline{\quad \ +50}\\.\quad 65=t_f

Colt1911 [192]

Responder:

120 maneras.

Explicacion paso a paso:

Cinco tipos diferentes de semillas.

El numero de formas de organizar, n, a diferencia de los objetos en una linea es n!

Entonces, para sembrar 5 tipos diferentes de flores, serian 5!

5! = 5 * 4 * 3 * 2 * 1 = 120 vias.

Por lo tanto, hay 120 formas de sembrar las cinco semillas.

Hablo ingles y escribo ingles. Espero que entiendas. Acabo de utilizar el traductor de Google para intentar que la respuesta sea mas clara para ti :).

An animal shelter has a total of 350 animals comprised of cats, dogs, and rabbits. If the number of rabbits is 5 less than one-h
Andrew [12]
This is the concept of algebra, suppose that the number of cats is x;
number of cats will be x-20
number of rabbits will be 3/2x
thus the total number of animals will be:
x+(x-20)+3/2x=350
7/2x=350+20
7/2x=370
x=370*2/7
x=105.7=106
therefore we conclude that there we 106 cats in the shelter

Se tiene la sucesión 3, 8, 13, 18, 23 … ¿Cuáles son los siguientes dos términos y cuál es la regla general?
V125BC [204]

Respuesta:

28; 33

A (n) = 5n - 2

Explicación paso a paso:

A partir de los datos dados, 3, 8, 13, 18, 23…, podemos ver que cada valor sucesivo de la serie aumenta en 5;

Por lo tanto, los siguientes dos términos de la serie deberían ser:

23 + 5 = 28

28 + 5 = 33

La serie es una progresión aritmética:

Recuerde la fórmula general:

A (norte) = a + (norte - 1) d

Donde, a = Primer término = 3; d = diferencia común = 5

n = enésimo término

A (n) = 3 + (n-1) 5

A (n) = 3 + 5n - 5

A (n) = 5n - 2
