Como se saca el volumen de una piscina rectangular mide 10 m de largo y 4 m de ancho y se necesita lennar con 100000 litros e agua
Answers
Complete Question
En una piscina con forma rectangular mide 10 metros de largo y 4 metros de
ancho y se sabe que para llenar la piscina se necesitan 100 000 litros de agua.
a) ¿Cuál es el volumen de la piscina?
b) ¿Cuál es la profundidad de la piscina?
Answer:
a) ¿Cuál es el volumen de la piscina?
= 100 m³
b) ¿Cuál es la profundidad de la piscina?
= 2.5m
Step-by-step explanation:
a) Se nos da la cantidad de litros de agua necesarios para llenar la piscina = 100000 litros
Conversión a cm³
1 litro = 0.001 m³
100000 litros = x
x = 100000 × 0.001 m³
x = 100 m³
b) La profundidad de la piscina se calcula como:
Volumen de la piscina ÷ (Largo × Alto)
Longitud = 10 m
Altura = 4 m
Por eso,
100 m³ ÷ (10 m × 4 m)
100 m³ ÷ 40 m²
= 2.5 m
Respuesta:
a) 1000m³
b) 25m
Explicación paso a paso:
Pregunta completa;
Piscina de forma rectangular, mide 10 metros de largo por 4 metros de alto.
de ancho y se sabe que se necesitan 100.000 litros de agua para llenar la piscina.
a) ¿Cuál es el volumen de la piscina?
b) ¿Cuál es la profundidad de la piscina?
Dado que 1m³ = 1000litros
x = 100.000 litros
Cruz multiplicar
100.000 * 1 = 1000x
100.000 = 100x
x = 100.000 / 100
x = 1000
Por lo tanto, el volumen de la piscina es de 1000 m³.
Voume = largo * ancho * profundidad
1000 = 10 * 4 * d
1000 = 40 días
d = 1000/40
d = 25
Por lo tanto, el tanque tiene 25 m de profundidad.
Jeanne goes to the city park every 7 days for walk. Susan goes to the park every 10 days. If they both went to the park today and met each other, after how many days again will they be in the park and meet again?
Answers
Answer:
70 days
Step-by-step explanation:
We solve using Lowest Common Denominator method
Find and list multiples of each number of days for a walk until the first common multiple is found. This is the lowest common multiple.
Jeanne goes to the city park every 7 days for walk. Susan goes to the park every 10 days.
Hence:
Multiples of 7:
7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84
Multiples of 10:
10, 20, 30, 40, 50, 60, 70, 80, 90
Therefore,
LCM(7, 10) = 70
Therefore, the number of days in which they will they be in the park and meet again is 70 days

How does the range of g(x)=6/x compare with the range of the parent function f(x)=1/x?
Answers
Answer:
The range of both [tex]f(x)[/tex] and [tex]g(x)[/tex] is all nonzero real numbers.
Step-by-step explanation:
The range of the function is the set of real number for [tex]y[/tex]. The rational function of the form [tex]y = \frac{a}{x}[/tex], where [tex]a[/tex] is a constant, has a range represented by the subset of nonzero real numbers. This is: [tex]Ran\{f(x)\} = \mathbb{R}-\{0\}[/tex]
Hence, the correct answer is: The range of both [tex]f(x)[/tex] and [tex]g(x)[/tex] is all nonzero real numbers.

Una maestra esta comprando lapices para su salon de clases. Si una docena de lapices cuesta $0.79 puede comprar lapices con $5?
Answers
Answer:
Cantidad total de lapices= 76
Step-by-step explanation:
Dada la siguiente información:
Costo por docena= $0.79
Presupuesto total= $5
Para calcular la cantidad total de lapiceras que se pueden comprar con $5, debemos usar la siguiente formula:
Cantidad total de lapices= presupuesto total / costo por docena
Cantidad total de lapices= 5 / 0.79
Cantidad total de lapices= 6.33
Para ser mas exactos:
0.33*12= 4
Cantidad total de lapices= 6*12 + 4
Cantidad total de lapices= 76

For the arithmetic sequence beginning with the terms {-2, 0, 2, 4, 6, 8...}, what is the sum of the first 18 terms?
Answers
Answer:
The sum of the first 18 terms is 270.
Step-by-step explanation:
First the 18th term is calculated which is gotten using the following steps below:
an = a1 + d ( n - 1 )
Where, an =18th term
a1= first term (-2)
d = difference
n = 18
Therefore, 18th term
an= -2 + 2 (18 - 1)
= -2 + 2 (17)
= -2 + 34
18th term = 32
To calculate the sum of the first 18th terms the following steps are used,
Sn = n(a1 + an)/2
Where,
Sn = sum of 18th term
n = 18
a1 = -2
an = 18 term
Therefore,
Sn = 18 (- 2+ 32)/2
= 18 (30)/2
= 18 ×30 /2
= 540/2
= 270

B) x=3, y = 0
C) No solution
D) Infinitely many solutions
Answers
Answer:
no solution.
Step-by-step explanation:
given that, y = 3x-1
so,
in equation, 3x-y = 9
putting the value of y here,
3x-(3x-1) = 9
3x-3x+1 = 9
3x and 3x is cancelled.
hence, no solution
