Answer:
D. 22
Step-by-step explanation:
Con la información proporcionada sabes que el administrador puede alimentar 220 vacas durante 45 días y puedes deducir que si el número de vacas aumenta el alimento duraría menos días, lo que significa que estas magnitudes son inversamente proporcionales. Por esto, para encontrar la respuesta debes usar una regla de tres inversa:
220 vacas → 45 días
450 vacas → x
x=(220*45)/450
x= 22 días
De acuerdo a esto, la respuesta es que el administrador podrá alimentar a las 450 vacas por 22 días con la misma cantidad de alimento.

To find the area of a circle, start with the formula for the area of a circle.
Area =
Notice that we are given the radius of the circle so we can plug the radius into our formula.
Area = (4 cm)²
Area = 16π cm².
Now, remember that π is approximately equal to 3.14. We can estimate the area of the circle by plugging in 3.14 for π.
(16) (3.14) = 50.24 cm³.
Therefore, the area of the circle is approximately equal to 50.24 cm³.
It's B 29%
You know there's a 20% chance of wind and no sun.
And there must be a 70% chance of no sun. Since there's a 30% chance of sun
If you divide 0.20 / 0.70 you get .2857 which rounds to 29%.
