Answer:
Los pinos ocupan 
o <em>1 millón seiscientos veinte mil metros cuadrados</em>.
Step-by-step explanation:
Una manera de resolver este problema es la siguiente:
En palabras, 
, o <em>dos kilómetros cuadrados</em> son iguales a <em>2 millones de metros cuadrados</em>.
Sabemos que:
- Estos de bosque lo ocupan hayas y pinos, y, adicionalmente,
- Las hayas ocupan
.
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:
¿Cuántos metros cuadrados ocupan los pinos?
Los pinos ocupan, entonces, o <em>1 millón seiscientos veinte mil metros cuadrados</em>.
Answer:
y = -2/5x + 3
Step-by-step explanation:
Start with your given:
2x + 5y = 15
Isolate y:
5y = -2x + 15
Divide 5 on both sides:
y = -2/5x + 3
Hope that helped. Hang in there! :)
La of sine:
sinC/c = sinB/b==> sin 37°/8 = sin B/12 ==> sin B = 0.903
arcsinB or sin⁻¹ B = 64.5°, & sin (B°) = sin (180° - B°), then
sin(64.5) = sin(180°-64.5°) ==> B = 64.5° or 115.5°
For the answer to the question above, to solve these questions, use this formula: X3= F(X1-X2) Y3= F(Y1-Y2)
Where X3 is the X value in the coordinate your solving for, F is the fraction,
X1 is the first X and X
2 is the second X Plug in your numbers to fit this: X3= 1/4 x (0--2) Y3= 1/4 x (4- -3) By solving you get: (-.5, 1.75)
bearing in mind that 1Kg ≈ 2.2lbs.
so, if a baby is say 2.2lbs, and then it doubles in weight, to 4.4lbs.
well, we know when the baby was 2.2lbs it was exactly 1Kg, but when it went up to 4.4lbs, is it 2Kgs? well, yes, 2Kgs = 2.2 + 2.2 or 2(2.2).
so, multiplying the lbs value by some factor, will retain the Kg:lbs ratio.
