The answer is 110. I just took the quiz on k12
Answer:
taking away is subtracting so if you take away 10 from 67 the equation would be 67-10
the answer would be 57
Answer:
$180.00
Step-by-step explanation:
300 * .40 = 120
300 - 120 = 180.00
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: second option
Step-by-step explanation:
You know that it is a right triangular window frame.
Then, you can use the Pythagoren Theorem to find the lenght of the third side:
Where "a" is the hypotenuse (or the longest side), and "b" and "c" are the legs .
Then, you can solve for one of the legs:
Since you know the lenght of the hypotenuse and the lenght of one leg, you can substitute values.
Therefore, you get:
