For the purpose of showing the solution to this item, we let the basis in which we are to determine the number of trains that passed through be 1 day. That being said, we convert 1 day to number of minutes by using the correct conversion factor and dimensional analysis as below.
(1 day)(24 hours/1 day)(60 minutes/1 hour) = 1440 minutes
Then, divide the calculated number of minutes by 20.
number of trains = 1440 minutes x (1 train / 20 minutes)
number of trains = 72 trains
Answer: 72 trains
Answer:
The correct option is C
C) 76°
Step-by-step explanation:
The question is incomplete because the figure is not given. I have attached the figure of the same question below. Consult it for better understanding.
We can see in the figure that <2 and <4 are opposite angles, therefore these are equal.
<2 = <4
126 = 7x
x = 18
Similarly we can also see that <5 and <7 are also opposite angles, therefore they are equal too.
<7 = <5
<7 = 4x+4
Substitute x=18
<7 = 4(18) + 4
<7 = 76°
Answer:
El área y volumen del prisma cuadrangular mencionado son respectivamente:
- <em>Área =</em>
- <em>Volumen =</em>
Step-by-step explanation:
Para solucionar este ejercicio debes recordar que un prisma cuadrangular tiene como base y como superficie cuadrados, por lo tanto, para calcular el área de dicho cuadrado puedes utilizar la siguiente fórmula:
- <em>Área de un cuadrado = </em>
Ya que el ejercicio nos da el valor de la arista (4 metros), podemos reemplazarla en la ecuación y calcular:
- Área de un cuadrado =
- Área de un cuadrado =
Por último, para calcular el volumen debes multiplicar el área superficial, el área del cuadrado calculado, por la altura del prisma, cuyo valor dentro del enunciado es de 6 metros, de esta forma:
- <em>Volumen de un prisma cuadrangular = área superficial * altura</em>
- Volumen de un prisma cuadrangular = *
- Volumen de un prisma cuadrangular =
Como puedes ver tras los cálculos, <u><em>el área superficial del prisma es de </em></u><u><em> y su volumen es </em></u>.
