Answer:
Step-by-step explanation:
1- Un avión se desplaza a 720 km/h.¿Que tiempo tarda en recorrer 120.000.000 cm?
x = 120.000.000 cm = 1200.000 m (Dividir para 100)
v = 720 km/h = 200 m / s (Dividir para 3,6)
x = v*t
t = x / v
t = 12000000 / 200
t = 6000 segundos = 100 minutos = 1 hora 40 minutos
2-Un auto recorre 430 km en 6 h 30 min 18 s.¿Cual es su velocidad en km/h?
x = 430 Km = 430000 m
t = 6 h 30m 18 s
t = 6 * 3600 + 30 * 60 + 18
t = 21798 s
v = x / t
v = 430000 / 21798
v = 19,72 m/s = 71 km/h (Multiplica por 3,6)
3-Una moto se desplaza a 144 km/h durante 820 min. calcular la distancia recorrida
v = 144 km/s = 40 m/s
t = 820 min * 60 = 49200 s
x = v*t
x = 40 * 49200
x = 1968000 m = 1968 Km
4-un atleta corre a 9 m/s.¿Cuanto tiempo tarda en recorrer 10,9 Km?
v = 9 m/s
x = 10,9 km = 10900 m
t = x / v
t = 10900 / 9
t = 1211,11 s = 20 minutos 11 segundos
Answer:
Step-by-step explanation:
The altitude falls in the middle of the line.
So, the point at which it falls in the bottom line is the midpoint, so the length of the blue triangle would be 6/2 = 3
So, the blue triangle has length of 3 and height of H and hypotenuse of 10.
Now, we will use Pythagorean Theorem to solve for H. The theorem is:
Leg^2 + Another Leg^2 = Hypotenuse^2
We know one leg of the triangle is 3 and another leg is H and hypotenuse is 10, so we substitute and solve:
This is the exact answer for H
The answer is 60 this is the last
Answer:
1 kilometer = 1000 meters
or
0.001 kilometers = 1 meter
Answer:
y=5x+1
Step-by-step explanation:
If you look closely at each side, you will see that the x increases by one and the y increases by five.
To get to zero (0) from one (1), you need to substract one.
Every time one is subtracted for x, 5 is subtracted from y.
6-5=1
