0.660 divided by 4.775 is roughly 0.1382
Answer: I don’t understand
Step-by-step explanation:
Next time actually ask something about college math
2x-6=0
2x-6+6=0+6
2x=6
2x/2=6/2
x = 3
Un objeto cae accidentalmente de un vehículo con una velocidad de
50 km / hy recorra 20 m antes de detenerse.
Calcular:
a) La aceleración:
b) El tiempo que tarda en detenerse:
Responder:
1.439 s
-9,645 m / s²
Explicación paso a paso:
Dado que:
Velocidad en m / s = (50 * 1000) / 3600 = 13.899 m / s
Distancia (d) = 20
Tiempo = distancia / velocidad
Tiempo = 20 / 13.889
Tiempo = 1.439 s
Aceleración (a):
Cambio de velocidad / tiempo empleado
= (0 - 13,889) / 1,439
- 13.889 / 1.439
= -9,645 m / s²
Answer:
2770.9 in³
Step-by-step explanation:
A cylinder has a base radius of 7in and a height of 18in. What is its volume in cubic inch to the nearest tenths place?
The formula for the volume of a cylinder is given as:
πr²h
r = radius = 7 in
h = height = 18 in
Hence:
Volume of the cylinder = π × 7² × 18
= 2770.88472 in³
Approximately to the nearest tenth = 2770.9 in³
