Answer:

Ok, la distancia inicial entre los trenes es de 200 km:

IPa(0s) - P(0s)I = 200 km.

donde Pa representa la ubicación del tren A y Pb representa la ubicación del tren B.

La velocidad del tren A es:

Sa = 50 km/h

Sb = 65 km/h

Recuerda la relación:

Distancia = Velocidad * tiempo.

<pAsí, en una hora, la distancia recorrida por el tren A es:

Distancia = 50 km/h * 1 h = 50 km

<pLa distancia recorrida por el tren B es:

distancia = 65 km/h * 1 h = 65 km.

<pSi al inicio el tren A está 200 km adelante del tren B, entonces tenemos:

Pa - Pb = (Pa(0s) + 50 km) - (Pb(0s) + 65 km)

= (Pa(0s) - Pb(0s)) + (50 km - 65 km) = 200 km - 15 km = 185 km.

<pAhora, si el tren B estaba 200 km por delante del tren A, tenemos:

Pb - Pa = (Pb(0s) + 65 km) - (Pa(0s) - 50 km) =

(Pb(0s) - Pa(0s)) + (65 km - 50 km) = 200 km + 15 km = 215 km

He dot plots show the number of hours a group of fifth graders and seventh graders spent playing outdoors over a one-week period
babunello [11817]
In the seventh-grade data, the left side appears similar to the right side, unlike in the fifth-grade data. In seventh grade, we can divide the dots into two equal segments, one ranging from 0 to 3 and the other from 4 to 7. The distribution in the first segment is {2, 2, 3, 5}, while the second segment has {5, 3, 3, 1}. These sides mirror each other. When attempting a comparable division in the fifth-grade data, we find one segment from 1 to 4 with a distribution of {2, 3, 1, 4}, and another from 5 to 8 with a distribution of {5, 5, 2, 2}. In this case, the left side does not reflect the right side, indicating a lack of symmetry.

AnnZ [12381]

Answer:

According to my cupcake recipe, it yields $12$ cupcakes and calls for $1\frac{1}{2}$ sticks of butter. I can only purchase whole sticks of butter.

Consequently, a single whole stick of butter will suffice to prepare $100$ cupcakes.

Which pair represents the same complex number?
tester [12383]
In this scenario, we have the complex number:
1 + i
The corresponding pair is represented as:
root (2) * (cos (pi / 4) + i * sin (pi / 4))
By rewriting this, we have:
root (2) * (root (2) / 2 + i * (root (2) / 2))
(2/2 + i * (2/2))
(1 + i)
Answer:
option A shows a pair representing the same complex number
