Find 3 consecutive odd integers whose sum is 225, explain please

1 answer:

5 0

3 odd integers have a property that they average up to the middle large one. Let's say we have 3, 5, and 7. 3 is 2 less than 5 and 7 is 2 more than 5. so when you add them it equals 2 times 5.
After we know that, the sum of 3 odd integers is just 3 times the middle number. ex. 3+5+7 = 3 times 5 = 15
Then we know the some number times three = 225. we find out that the middle number is 75, so the other two are 73 and 77

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 1 millón seiscientos veinte mil metros cuadrados.

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 dos kilómetros cuadrados son iguales a 2 millones de metros cuadrados.

Sabemos que:

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

De esta manera, la parte que ocupan los pinos es el total del bosque menos el área ocupada por las hayas. 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 1 millón seiscientos veinte mil metros cuadrados.
