Un bosque de 2 km2 está formado por hayas y pinos. Las hayas ocupan 380.000 m2 ¿Cuántos metros cuadrados ocupan los pinos?
Ivanshal [37]

Answer:

Los pinos ocupan \\ 1620000m^{2} o <em>1 millón seiscientos veinte mil metros cuadrados</em>.

Step-by-step explanation:

Una manera de resolver este problema es la siguiente:

\\ 1km^{2} = 1km * 1km = 1000m * 1000m = 1000000m^{2}

\\ 2km^{2} = 2km * 1km = 2000m * 1000m = 2000000m^{2} = 2 * 10^{6}m^{2}

En palabras, \\ 2km^{2} = 2000000m^{2}, o <em>dos kilómetros cuadrados</em> son iguales a <em>2 millones de metros cuadrados</em>.

Sabemos que:

  1. Estos \\ 2km^{2} = 2000000m^{2} de bosque lo ocupan hayas y pinos, y, adicionalmente,
  2. Las hayas ocupan \\ 380000m^{2}.

De esta manera, <em>la parte que ocupan los pinos es el total del bosque menos el área ocupada por las hayas</em>. Por lo tanto, el área ocupada por los pinos es:

\\ 2000000m^{2} - 380000m^{2}

\\ 1620000m^{2}

¿Cuántos metros cuadrados ocupan los pinos?

Los pinos ocupan, entonces, \\ 1620000m^{2} o <em>1 millón seiscientos veinte mil metros cuadrados</em>.

Answer:

The height = 18 inches

Step-by-step explanation:

The volume = area of the base × height

Area of the base = 40.5 inches²

The volume = 729 inches³

729 = 40.5 × height

Height = 729 ÷ 40.5 = 18 inches

ipn [44]

Answer:

1

Step-by-step explanation:

85 beads 3 bracelets

83 divided by 3 = 28.333

Rounded is 28 and adding the 0.333's you get

0.999.

0.99 is left over which rounds to 1 so I say 1 is left over

<u>im not a math whizz</u><u> but this seemed to make sense to me</u>
