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>.

Help please I need it!!

First find the slope of A.

Slope=(y2-y1)/(x2-x1)=(4-0)/(0--7)=4/7

For a line to be perpendicular to line A, it must have a slope that is the negative reciprocal of the slope of A.  Mathematically:

m1*m2=-1 and in this case the perpendicular line will have a slope of:

4m/7=-1

4m=-7

m=-7/4 

So the slope of the line perpendicular to A is -7/4
