A lunar </span>eclipse<span> lasts for hours as the moon slowly orbits through the Earth's shadow.</span>

Un niño compro globos, gasto 1/5 y luego 2/3 de su ahorro ¿que parte gasto y que parte le quedo?​
zlopas [31]

Answer:

El niño gastó \frac{8}{15} y le quedó \frac{7}{15} del ahorro.

Explanation:

Sea m la cantidad total inicial de su ahorro. A continuación, transformamos cada oración en una expresión matemática:

(i) <em>Un niño gasta </em>\frac{1}{5}<em> de su ahorro inicial</em>:

p_{1} = \frac{1}{5}\cdot m (1)

(ii) <em>Luego, gasta </em>\frac{2}{3}<em> de su ahorro actual</em>:

p_{2} = \frac{2}{3}\cdot (m-p_{1}) (2)

p_{2} = \frac{2}{3}\cdot \left(m-\frac{1}{5}\cdot m)

p_{2} = \frac{2}{3}\cdot \frac{4}{5}\cdot m

p_{2} = \frac{8}{15}\cdot m

Ahora, la porción remanente del ahorro es:

p_{3} = m - p_{2}

p_{3} = \frac{7}{15}\cdot m

El niño gastó \frac{8}{15} y le quedó \frac{7}{15} del ahorro.

Poema sobre la economía de Republica Dominicana
Anon25 [30]

Answer:

Pedro Mir, (born June 3, 1913, San Pedro de Macorís, Dom.Rep.—died July 11, 2000, Santo Domingo), Dominican poet, whose poems celebrate the working class and examine aspects of his country’s painful past, including colonialism, slavery, and dictatorship.

By his mid-30s Mir had developed a prominent literary reputation. His social commentary, however, angered Dominican dictator Rafael Trujillo, and Mir was forced into exile in 1947. He spent the next 15 years in Cuba (where he published what is perhaps his best-known poetry collection, Hay un país en el mundo [“There Is a Country in the World”], in 1949), Mexico, and the Soviet Union. Mir returned to the Dominican Republic in 1962, a few months after Trujillo’s assassination, and continued his prolific writing career, publishing essays and novels as well as poems.
