Answer:

Option C. 1,024 bacteria

Step-by-step explanation:

We are given that a bacteria culture begins with 4 bacteria which double in size every hour. And we have to find that how many bacteria exist in the culture after 8 hours;

So, Number of bacteria after one hour = 4 * 2 = 8

     Number of bacteria after two hours = 8 * 2 = 16

     Number of bacteria after three hours = 16 * 2 = 32

     Number of bacteria after four hours = 32 * 2 = 64

     Number of bacteria after five hours = 64 * 2 = 128

     Number of bacteria after six hours = 128 * 2 = 256

     Number of bacteria after seven hours = 256 * 2 = 512

     Number of bacteria after eight hours = 512 * 2 = 1,024

Therefore, 1,024 bacteria exist in the culture after 8 hours .

RSM HOMEWORK HELP!!!
Gnesinka [82]

Answer:

Step-by-step explanation:

∠CAB = 33       {alternate interior angles}

5x = 33 + 2x    { exterior angle equals sum of opposite interior angles}

5x - 2x = 33

3x = 33

x = 33/3

x = 11

∠B = 2x = 2* 11 = 22

∠ECB = 5x = 5*11 = 55

3x/2y=11 x+y/2=7 igualacion<br> Alguien me puede ayudar
bearhunter [10]

La solución del sistema de ecuaciones es igual a (x, y) = (308/47, 42/47).

<h3>¿Cómo resolver un sistema de ecuaciones linear por igualación?</h3>

Los sistemas de ecuaciones basadas en entidades algebraicas se resuelven mediante procedimientos algebraicos. Grosso modo, el método de resolución por igualación consiste en despejar una variable en dos ecuaciones del sistema para eliminarla y reducir el número de ecuaciones <em>lineales</em> y el número de variables.

A continuación, presentamos una aplicación del método de eliminación:

\frac{3\cdot x}{2\cdot y} = 11

x = \frac{22\cdot y}{3}

x + \frac{y}{2} = 7

x = 7 - \frac{y}{2}

\frac{22\cdot y}{3} = 7 - \frac{y}{2}

\frac{47\cdot y}{6} = 7

y = 42/47

x = 7 - \frac{y}{2}

x = 308/47

La solución del sistema de ecuaciones es igual a (x, y) = (308/47, 42/47).
