Step-by-step explanation:
Datos;
una locomotora
recorre 5 horas
a una velocidad de 82 km/h
Se asume que la locomotora lleva un movimiento rectilíneo uniforme.
Su recorrido esta descrito por la siguiente ecuación de posición;
x = x₀+ v · t
x-x₀ = d = v · t
siendo;
d = distancia recorrida
v = 82 km/h
t = 5 horas
Sustituir:
d = (82)(5)
d = 410 km
82km/h * 5h= 410km
La locomotora recorrerá 410km
Answer:
Step-by-step explanation:
Answer:
55%
Step-by-step explanation:
probability of something happening = p
probability of that thing not happening = 1 - P
45%= 45/100= 0.45
therefore, the probability of snow today = 0.45
therefore,
probability there will be no snow=1 - 0.45 = 0.55
probability there will be no snow= 0.55
convert 0.55 back to percentage= 0.55×100= 55%
probability there will be no snow= 55%
21
half the height is 3
a=7
b=x
3(7+x)=84
21+3x=84
place the like terms on one side
84-21=3x
63=3x
x=21
