Answer:
El período paleolítico corresponde a de la época prehistórica.
Step-by-step explanation:
En primer lugar, se determina la extensión de tiempo, medida en años, tanto de la época prehistórica como el período paleolítico: (Nótese que el signo negativo significa a.C.)
Época Prehistórica
Período Paleolítico
La fracción de la época prehistórica que corresponde al período paleolítico es:
El período paleolítico corresponde a de la época prehistórica.
The first thing we must do for this case is to define variables.
We have then:
x: ticket for seats in section a
y: ticket for seats in section b
z: ticket for seats in section c
We write the system of equations:
50x + 40y + 20z = 335000
x + y + z = 9500
y = x + z + 500
Solving the system we have:
x = 1500
y = 5000
z = 3000
Answer:
ticket for seats in section a = 1500
ticket for seats in section b = 5000
ticket for seats in section c = 3000
Consider this option:
1.the equation of the circle using its centre and point (0;-4) is:
x²+y²=4.
2. to substitute given point (23;2) into the equation of the circle:
23²+2²≠4
answer: this point does not belongs to the circle.
