Answer:

Part A : 9.555 . 10^38

Part B : 7.4 . 10^-3

Step-by-step explanation:

<h3>Part A</h3>

3.9 \: . \:  {10}^{33} . \: 2.45 \: . \:  {10}^{5}  \\ 3.9 \: . \: 2.45 \: . \:  {10}^{33 + 5}  \\ 9.555 \: . \:  {10}^{38}  \\

<h3>Part B</h3>

7.4 \: . \:  {10}^{ - 3}mm  \\ 7.4 \: . \:  \frac{1}{ {10}^{3} }  \\ 0.0074mm

7.4 \: . \:  {10}^{3}mm  \\ 7.4 \: . \: 1000 \\ 7400mm

A blood cell is too small. So the more reasonable measurement is 0.0074mm.

jolli1 [7]

The values of  x are -22 and -2 and there are not extraneous solutions

<h3>How to solve the equation?</h3>

The equation is given as:

2|x + 7|= x - 8

Expand the absolute bracket

|2x + 14|= x - 8

Remove the absolute bracket

2x + 14 = x - 8 and 2x + 14 = -x + 8

Evaluate the like terms

x = -22 and 3x = -6

This gives

x = -22 and x = -2

Hence, the values of  x are -22 and -2 and there are not extraneous solutions

A partir del 1.° de diciembre, un camión de helados visita la calle de Sara cada 3 días y la calle de Ema cada 5 días. ¿Cuáles s
777dan777 [17]

Answer:

Los primeros 2 días que el camión visita ambas calles el mismo día es el 15 y 30 de diciembre.

Step-by-step explanation:

Los múltiplos de un número son todos los posibles resultados de multiplicar ese número por todos y cada uno de los números naturales.

Es decir, los múltiplos de un número natural son los números naturales que resultan de multiplicar ese número por otros números naturales.

El conjunto de los múltiplos de un número determinado (salvo el cero) es infinito, pues existen infinitos naturales para multiplicar.

Para determinar cuáles son los primeros 2 días que el camión visita ambas calles el mismo día, debes encontrar los múltiplos de 3 y 5:

múltiplos de 3: 3; 6; 9; 12; 15; 18; 21; 24; 27; 30

múltiplos de 5: 5; 10; 15; 20; 25; 30; 35; 40; 45; 50

Podes observar que los 2 primeros números comunes o que coinciden entre los múltiplos de 3 y 5 son 15 y 30. Esto quiere decir que <u><em>los primeros 2 días que el camión visita ambas calles el mismo día es el 15 y 30 de diciembre.</em></u>
