Un móvil avanza con mru a razón de 25 m/s durante 2,54 h. Cuál es la distancia recorrida por el móvil
Brut [27]

Answer:

La distancia recorrida por el móvil es 228.600 m

Explanation:

El movimiento rectilíneo uniforme MRU es el movimiento que describe un cuerpo o partícula a través de una línea recta a velocidad constante. Es decir:, en este caso el movimiento es lineal en una única dirección  y la velocidad de desplazamiento es constante.

La velocidad es una magnitud física que expresa la relación entre el espacio recorrido por un objeto y el tiempo empleado para ello mediante la expresión:

velocidad=\frac{distancia}{tiempo}

En este caso:

  • velocidad= 25 m/s
  • distancia= ?
  • tiempo= 2,54 h= 9144 s (siendo 1 h= 3600 s)

Reemplazando:

25 \frac{m}{s} =\frac{distancia}{9144 s}

y resolviendo obtienes:

distancia= 25\frac{m}{s} *9144 s

distancia= 228.600 m

<u><em>La distancia recorrida por el móvil es 228.600 m</em></u>

List four rules for rounding numbers.
sveta [45]

Answer:

the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30

Rounding fractions works exactly the same way as rounding whole numbers. The only difference is that instead of rounding to tens, hundreds, thousands, and so on, you round to tenths, hundredths, thousandths, and so on.

By rounding off, you could easily figure out that you would need about $6.00 to pay for your groceries.
