A 1000 gallon tank, initially full of water, develops a leak at the bottom. Given that 300 gallons of water leak out in the firs

Over [174]

Answer:

option F

Step-by-step explanation:

given,

capacity of tank = 1000 gallon

volume of water leak = 300 gallon

time = 30 min

water is leaking at the rate

formula used

$A = B e^{-kt}$

At t = 0 A = 1000 gallons

$1000= B e^{-k\times 0}$

B = 1000

$A = 1000 e^{-kt}$

at t = 30 A = 700

$700= 1000 e^{-k\times 30}$

$e^{-k\times 30}=0.7$

taking ln both side

$-k\times 30=ln(0.7)$

$k=-\dfrac{ln(0.7)}{30}$

now,

$A = 1000 e^{\dfrac{ln(0.7)}{30}t}$

$A = 1000\times 0.7 e^{\dfrac{t}{30}}$

$A = 700 e^{\dfrac{t}{30}}$

hence, the correct answer is option F

1. Analiza cada problema y realiza su diagrama.

Maru [420]

Invitamos cordialmente a leer el desarrollo del problema para mayor detalle sobre el análisis de la situación y la construcción del diagrama.

<h3>Cómo construir un diagrama a partir de un enunciado</h3>

En esta pregunta debemos elaborar un diagrama de flujo, puesto que el enunciado muestra de manera evidente una clasificación de los viajeros según las ciudades de destino.

Nótese que se trata de un diagrama bastante simple, dado que no existe evidencia de jerarquización entre las ciudades mencionadas.

Tras una lectura cuidadosa del enunciado encontramos que de 25 estudiantes de cuarto grado "C" que decidieron irse de viaje, 10 viajaron a Paracas, 15 viajaron a Arequipa, 7 viajaron a los dos lugares citados y 3 viajaron a Chosica.

A continuación, presentamos el diagrama de flujo asociado a este caso en la imagen adjunta abajo.

Evaluate <br> 1/3 ÷ 2/5 =<br> Give your answer as a fraction in its simplest form.

Softa [21]

Answer:

5/6

Step-by-step explanation:

Since 1/3÷2/5 can also be written as 1/3/2/5

So the ÷ can then be converted to × and 2/5 will change to 5/2

So let's solve

1/3×5/2

5/6

Since there is no common number that can divide the two

So the final answer is 5/6
