Which expression is equivalent to (10x)^-3?

Mathematics

(10x)^(-3)
= 1/[(10x)^3]
= 1/[10^3 * x^3]
= 1/(1000x^3)

The final result is 1/(1000x^3), and none of the given choices seem correct. (Option C would be correct if it used round brackets.)

Hope this helps~

tester [11989]

Answer:

The constant pay of $25 signifies the intercept

Step-by-step explanation:

To address this query, we first need to comprehend and relate it to the formula for a straight line.

i.e y= mx+c  this represents the line's equation

where m= slope

           y= dependent variable

           x= independent variable

          c= intercept

Given

y= 25+5h

by comparing the two expressions, we can observe that

25 is equivalent to c, which denotes the intercept

Un globo vuela entre dos ciudades A y B, que distan entre sí 1.500 m. Los tripulantes del globo ven la ciudad A con un ángulo de
Inessa [12248]

Respuesta:

La altitud del globo por encima del nivel del suelo es de 449,6 metros.

Explicación paso a paso:

El enunciado no está completo. El texto completo es: "Un globo se desplaza entre las ciudades A y B, que se encuentran a 1.500 m de distancia. Los ocupantes del globo observan la ciudad A con un ángulo de depresión de 27°, mientras que, para la ciudad B, el ángulo es de 36°. ¿Cuál es la altura aproximada del globo con respecto al suelo?"

El diagrama que ilustra esta situación está en el archivo adjunto. Para calcular la altura del globo, se pueden emplear las funciones trigonométricas, siendo recomendable hacer uso de la función tangente para los ángulos de depresión mencionados:

Ciudad A

\tan 27^{\circ} = \frac{h}{1500\,m-x}

0,510 = \frac{h}{1500\,m-x}

Ciudad B

\tan 36^{\circ} = \frac{h}{x}

0,727 = \frac{h}{x}

Donde h y x representan la altura desde el suelo y la distancia horizontal desde la ciudad A.

Luego, se igualan las alturas en ambas ecuaciones para calcular la distancia horizontal del globo en relación a la ciudad A:

0,727\cdot x = 0,510\cdot (1500\,m-x)

1,237\cdot x = 765\,m

x = 618,432\,m

Por último, la altura del globo sobre el suelo se calcula como:

h = 0,727\cdot x

h = 0,727\cdot (618,432\,m)

h = 449,600\,m

La altura del globo respecto al nivel del suelo es 449,6 metros.

The gas tank in felizs car is 5/6 full each time he drives to or from work he uses 1/12 of a full tank of gas which equation rep
babunello [11394]

Answer:

\frac{1}{12}x = \frac{5}{6}\\ \\

Step-by-step explanation:

Given:

  • Fuel volume = 5/6
  • Each trip uses fuel = 1/12
  • Number of trips to work = x

Since 1/12 of the tank is used for each trip and the starting volume is 5/6, the equation can be represented as:

  • \frac{1}{12}x = \frac{5}{6}\\ \\

By solving the equation, we find:

  • x = \frac{5}{6}÷\frac{1}{12}
  • x = \frac{5}{6} × 12
  • x = 10

This means Felitz can make 10 trips to/from work with a tank filled to 5/6.
