Pentagon CRAFT has coordinates c(-2,1) r(-5,2) a(-6,7) f(-3,9) and t(-1,6) and is dilated by a scale factor of 2/3 at the origin
Vsevolod [243]

Answer:

First, we need to know the formula when a scale factor appears:

New coordinate =  (scale factor)*(old coordinate)

So using this formula we have:

1) c' = (-2,1)*2/3  

  c' = (-4/3,2/3)

2) r = (-5,2)*2/3

   r = (-10/3,4/3)

3) a = (-6,7)*2/3

   a = (-4,14/3)

4) f = (-3,9)*2/3

   f = (-2,6)

5) t = (-1,6)*2/3

   t = (-2/3,4)

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>.
