Responder:
Después de 40 días (11 de febrero)
Explicación paso a paso:
Dado que :
El avión 1 sale cada 8 días
El avión 2 sale cada 10 días
El avión 3 sale cada 20 días
Si todos se van el 2 de enero; La próxima fecha en que se irán juntos se puede obtener obteniendo el mínimo común múltiplo de los días de cada avión:
___8____10_____20
2 | _4____5______10
2 | _ 2____5______ 5
2 | _ 1 ____5______ 5
5 | _ 1 ____ 1 ______ 1
El mínimo común múltiplo es, por tanto;
2 * 2 * 2 * 5 = 40
Todos se irán juntos nuevamente después de 40 días:
(2 de enero + 40 días) = 11 de febrero

Answer:
+ 1) is an even number.
Take any n ∈ N, then n is either even or odd.
• Suppose n is even ⇒ n = 2m for some m ⇒ n(n + 1) = 2m(n + 1) ⇒ n(n + 1) is even.
• Suppose n is odd ⇒ n+ 1 is even ⇒ n+ 1 = 2m for some m ⇒ n(n+ 1) = 2nm ⇒ n(n+ 1)
is even. QED

Step-by-step explanation:
a>50A is greater than 50
a<50a<50
a≥50A is greater than or equal to 50
a≤50
Answer:
36 degrees =x
Step-by-step explanation:
If the polygon has 4 angles then it is a quadrilateral and must have 360 degrees. you can see that all angles in that polygon added up are 10x. If 10x=360 then x= 36 degrees, 2x=72 degrees, 3x=108 degrees, 4x=144 degrees
Answer:
n = 15
Step-by-step explanation:
A straight line equals 180 degrees
Angle SWT is congruent to angle XWV meaning:
SWT (55 degrees) = XWV (55 degrees)
Set up an equation:
3n + 80 + 55 = 180
Combine like terms
3n + 135 = 180
Subtract both sides by 135 to isolate variable n
3n = 45
Divide both sides by 3 to isolate variable n
n = 15
