Determinar que Recipiente tiene mayor densidad; el recipiente A pesa 1.2 toneladas y tiene un volumen de 120 m³ mientras que el recipiente B pesa 2.4 toneladas y tiene un volumen de 240 m³. ¿Cuál recipiente tiene mayor densidad?

Answers

Answer:

Ambos recipientes tienen la misma densidad, es decir, 10 kilogramos por metros cúbicos.

Step-by-step explanation:

Recordamos que la densidad de un material uniforme ([tex]\rho[/tex]), medido en kilogramos por metro cúbico, está definido por:

[tex]\rho = \frac{m}{V}[/tex] (1)

Donde:

[tex]m[/tex] - Masa, medido en kilogramos.

[tex]V[/tex] - Volumen, medido en metros cúbicos.

Ahora calculamos la densidad de cada recipiente:

Recipiente A ([tex]m =1200\,kg[/tex], [tex]V = 120\,m^{3}[/tex])

[tex]\rho = \frac{1200\,kg}{120\,m^{3}}[/tex]

[tex]\rho = 10\,\frac{kg}{m^{3}}[/tex]

El recipiente A tiene una densidad de 10 kilogramos por metro cúbico.

Recipiente B ([tex]m = 2400\,kg[/tex], [tex]V = 240\,m^{3}[/tex])

[tex]\rho = \frac{2400\,kg}{240\,m^{3}}[/tex]

[tex]\rho = 10\,\frac{kg}{m^{3}}[/tex]

El recipiente B tiene una densidad de 10 kilogramos por metro cúbico.

Ambos recipientes tienen la misma densidad, es decir, 10 kilogramos por metros cúbicos.

Answer:

  (a) after 5 minutes: tower 1 -- 1550 gallons; tower 2 -- 670 gallons

  (b) 1650-20m = 570+20m; m = 27 . . . minutes

Step-by-step explanation:

(a) At the rate of 20 gallons per minute, in 5 minutes the amount of water transferred will be ...

  (20 gal/min)(5 min) = 100 gal

That is, Tower 1 will have 100 gallons less: 1650 -100 = 1550 gallons

and Tower 2 will have 100 gallons more: 570 +100 = 670 gallons.

__

(b) The quantity in tower 1 is ...

  t1 = 1650 -20m

and the quantity in tower 2 is ...

  t2 = 570 +20m

These will be equal when ...

  t1 = t2

  1650 -20m = 570 +20m . . . . . equation for finding m

  1080 = 40m . . . . . . . add 20m-570

  27 = m . . . . . . . divide by 40

The equation w = 6m+4, relates how a dog's weight varies with age, where m represents its age in months, and the w represents its weight in pounds. How many months before the dog weighed 58 pounds?

Answers

Answer:

9 months

Step-by-step explanation:

Given the relationship of the dogs weight ang its age modeled by the equation;

w = 6m+4

m represents its age in months, and;

w represents its weight in pounds

Given

w = 58pounds

Required

number of months m before the dog weigh 58pounds;

Substitute w = 58 into the function and get m as shown;

w = 6m + 4

58 = 6m + 4

subtract 4 from both sides

58-4 = 6m+4-4

54 = 6m

divide both sides by 6

54/6 = 6m/6

9 = m

m = 9

Hence it will take 9months before the dog will weigh 58 pounds

In a​ company, ​95% of the workers are men. If 125 people work for the company who​ aren't men ​, how many workers are there in​ all? Use pencil and paper. Show two different ways that you can solve this problem.


ill give you brainliesttttt

Answers

Based on the percentage of men workers in the company, the total number of workers is 2,500.

What is the percentage?

The percentage is the fractional value of a variable concerning another.

Percentages are like ratios and proportions, which show the numerical relationship between the independent and dependent variables.

The percentage of men workers = 95%

The number of non-men workers = 125

The percentage of non-men workers = 5% (1 - 95%)

If 5% of the workers are 125, the total number of workers, 100% = 2,500 (125/5% x 100%).

Check:

Men workers = 95% = 2,375

Non-men workers = 5% = 125

Total = 2,500

Thus, given the percentage of men workers as 95%, the total number of workers in the company is 2,500.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

Given,

In a​ company, ​95% of the workers are men.

125 people work for the company who​ aren't men.

We need to find number of workers working in the company.

The percentage of men workers = 95%

The number of non-men workers = 125

The percentage of non-men workers = 5% (1 - 95%)

Men workers = 95% = 2,375

Non-men workers = 5% = 125

If 5% of the workers are 125

the total number of workers, 100% = 2,500 (125/5% x 100%).

Total = 2,500

Thus, given the percentage of men workers as 95%, the total number of workers in the company is 2,500.

Nixon has a square piece of wrapping paper that has a total area of 200 square inches. Which point on the number line below represents the measurement closest to the side length of the piece of wrapping paper​

Answers

Answer:

x = 14 inches

Step-by-step explanation:

The area of a square piece of paper is 200 square inches.

We need to find the point on the number line below represents the measurement closest to the side length of the piece of wrapping paper​. It is shown in the attached figure.

Area of a square = x², x is the side length

[tex]x=\sqrt{A} \\\\x=\sqrt{200} \\\\x=14.142\ \text{inches}[/tex]

Answers

Answer:

  y = 5x - 7

Step-by-step explanation:

slope m = (y₂ - y₁) / (x₂ - x₁)

              = (-12 - 3) / (-1 - 2)

              = (-12 - 3) / (-1 - 2)

              = -15 / -3

          m = 5

y-intercept using slope above and anyone point, let's use (-1, -12):

y = mx + b

-12 = -5 + b

b = -7

Answer:

{12}

Step-by-step explanation:

isolate the radical expression

[tex]\sqrt{3x} = x-6[/tex]

raise both sides to the index of the radical in this case 2

[tex](\sqrt{3x} )^{2} = (x-6)^2[/tex]

[tex]3x = (x-6)^2[/tex]

foil the right hand side or multiply (x-6)(x-6)

[tex]3x = x^{2} -6x-6x+36[/tex]

subtract 3x from both sides and combine like terms

[tex]0=x^{2} -15x+36[/tex]

factor

[tex]0=(x-12)(x-3)[/tex]

set each factor equal to zero and solve for x

x - 12 = 0 and x - 3 = 0

     x = 12 and     x  = 3

Check each answer by plugging them individually into the original equation if the come out true they are a solution.

Check :

[tex]\sqrt{3(12)}+10=12+4\\\sqrt{36}+10 = 8\\6+10 = 16\\16=16[/tex]           [tex]\sqrt{3(3)}+10=3+4\\\sqrt{9}+10=7\\3+10=7\\13\neq 7[/tex]

Investors buy a studio apartment for $120,000. Of this​ amount, they have a down payment of $12,000 . Their down payment is what percent of the purchase​ price? What percent of the purchase price would a ​$42,000 down payment​ be?

Answers

Answer:

The percentage for both the cases would be 100% and 35% respectively

Step-by-step explanation:

The computation of the percentage of down payment to the purchase price would be:

In the first case, the percentage would be

= Down payment ÷ Total amount

= $12,000 ÷ $120,000

= 100%

For the second case, the percentage would be

=  Down payment ÷ Total amount

= $42,000 ÷ $120,000

= 35%

The percentage for both the cases would be 100% and 35% respectively

La factura de celular del mes pasado ascendió a un total de $239 por un consumo de 269 minutos de llamada, mientras que la de este mes ascendió a $175 por un consumo de 141 minutos. El importe es la suma de una tasa fija (renta de línea) más un precio fijo por minuto. Calcular la tasa y el precio por minuto

Answers

Answer:

Costo fijo= $104.5

Costo unitario=  $0.5 por minuto

Step-by-step explanation:

Mes pasado:

$239 por 269 minutos

Mes corriente:

$175 por 141 minutos

Primero debemos calcular el cost por minuto de llamada:

Costo unitario= (costo total más alto - costo total más bajo) / (cantidad de minutos más alto - cantidad de minutos más bajo)

Costo unitario= (239 - 175) / (269 - 141)

Costo unitario=  $0.5 por minuto

Ahora, el costo fijo:

Costo fijo= costo total más alto - (costo unitario*cantidad de minutos más alto)

Costo fijo= 239 - (0.5*269)

Costo fijo= $104.5

Costo fijo= costo total más bajo - (costo unitario*cantidad de minutos más bajo)

Costo fijo= 175 - (0.5*141)

Costo fijo= $104.5

okay so for the #1 it says that it take 1/2 (half) a day to paint 1/4 of your bedroom and we want to know how many days it would take to paint all of the bedroom, so 4/4 of the bedroom.
We can say that
1/2(number of day) = 1/4(how much you painted)
to paint all of your room you would have to have painted 4/4 of your room
to get to 4/4 i multiplied 1/4 by 4
you do the same thing to 1/2 so 1/2•4=2
So it would take 2 days to paint all (4/4) of your bed room

I dont if im clear but just think about it
