The density of lead is 11.4g/cm^3 at 25 degrees C. Calculate the volume occupied by 25.0g of lead

ElenaW [278]

Answer:

2.193 cm³

Step-by-step explanation:

density is mass divided by volume:

$density = \frac{mass}{volume}$

you can manipulate the formula by multiplying with volume:

$density \times volume = mass$

then dividing by density:

$volume = \frac{mass}{density}$

in this case:

$volume = \frac{25g}{11.4 \frac{g}{cm} } = 2.193 { \: cm}^{3}$

A certain kind of bacteria growing on your kitchen counter doubles every 30 mins.. Assuming that you start with only one bacteri

natali 33 [55]

What you can do is start with the key details in it... the main ones are that the bacteria grows every 30 minutes, you start with 1 bacteria, and the end time is 180 minutes. Basically you know that 3 goes into 18 6 times so 30 goes into 180 6 times which means that if you started with 1 bacteria you will end up with 7. Understand?

Por qué crees que el valor de la media no aparece en la tabla y es un número decimal?

vovikov84 [41]

La media no aparece en la tabla ya que se requiere un calculo para encontrarla, además, es un número decimal pues corresponde a la suma de los resultados dividida en el número de días.

<h3>¿Qué es la media?</h3>

En matemáticas, la media o promedio corresponde a la suma de todos los valores dividida en el número total de valores. En este caso la media corresponde a la suma de las temperaturas dividida en el número de días.

Calcular la media:

Usando la formula anterior, calculemos la media:

16 + 19 +17 + 20 + 22 + 18 +15 = 127/7 = 18.7

El valor de la media es 18.7, al respecto se puede observar que:

Este valor no aparee en la tabla pues no corresponde a la temperatura de ningún día sino que debe ser calculado.
Este valor es decimal, lo que se común al hallar la media ya que se suman todos los valores y se dividen por un número determinado.

Nota: Esta pregunta esta incompleta. Aquí esta la parte faltante:

-4k^2-8k-3 = -3-5k^2

mel-nik [20]

$-4k^2-8k-3 = -3-5k^2 \\ \\ -4k^2 - 8k = -5k^2 \\ \\ 4k^2 + 8k - 5k^2 = 0 \\ \\ -k^2 + 8k = 0 \\ \\ 8k - k^2 = 0 \\ \\ k(8 - k) = 0 \\ \\ k = 0,8 \\ \\$

The final result is: k = 0, 8.
