Answer:
6×10⁶ cubic feet
30:1
Step-by-step explanation:
Water goes over Niagara Falls at a rate of 180 million cubic feet every 
hours.
Now, 180 million cubic feet ≡ 18×10⁷ cubic feet
and hours =30 minutes.
As the water is falling at a constant rate, hence, the unitary method of calculation can be applied.
Therefore, in 1 minute, the amount of water that goes over the falls will be
18×10⁷/30 =6×10⁶ cubic feet.
So, the amount of water passing over the falls is reduced in the ratio 30:1. (Answer)
Measure = 1/2 (120-30)
1/2(90)
45
Answer = 45°
Explicación paso a paso:
Pregunta 1
El contenido total de verduras = 220 g
La masa drenada es de 110 g.
¿Qué fracción representa la masa drenada del contenido total?
= 110/220
= 22/11
La fracción es 11/22
Pregunta 2
¿Qué fracción decimal corresponde a 1/4?
la fracción decimal que corresponde a 1/4 es 0,25
Pregunta 3
¿Cuánto porcentaje está representado por 1/4 o 0,25?
= 0,25 * 100
= 25%
Pregunta 4
¿Cuánto porcentaje del contenido total representa la masa drenada?
= 110/220 * 100
= 11/22 * 100
= 0,5 * 100
= 50%
