A 150 no container can hold 23.6 g of aluminum what is the density of the aluminum?
Drupady [299]

Answer:

# The density of the aluminum is 59/375 ≅ 0.157 g/cm³

# The volume of the container is 4/17 ≅ 0.235 cm³

# The mass of iron is 1225 g

Step-by-step explanation:

* Lets explain how to solve the problem

- Density is a measurement that compares the amount of matter

 of an object to its volume [ Density = mass/volume]

- Density is found by dividing the mass of an object by its volume

- The unit of measuring density is gram per centimeter³ (milliliter)

* Lets solve the problems

# A container of volume 150 cm³ can hold 23.6 g of aluminum

∵ Density = mass/volume

∵ The mass = 23.6 g

∵ The volume = 150 cm³

∴ The density = 23.6/150 = 59/375 ≅ 0.157 g/cm³

* The density of the aluminum is 59/375 ≅ 0.157 g/cm³

# The density of mercury is 13.6 g/cm³ at 23 C°

- A container can hold 3.2 g of mercury at this temperature

∵ Density = mass/volume

∵ The mass = 3.2 g

∵ The density = 13.6 g/cm³

∴ 13.6 = 3.2/volume

- By using cross multiplication

∴ The volume = 3.2/13.6 = 4/17 cm³

* The volume of the container is 4/17 ≅ 0.235 cm³

# The density of the iron is 4.9 g/cm³

- The beaker has a volume 250 ml

∵ Density = mass/volume

∵ The ml = cm³

∴ The volume of the beaker is 250 cm³

∵ The density = 4.9 g/cm³

∴ 4.9 = mass/250

- Multiply both sides by 250

∴ mass = 1225 g

* The mass of iron is 1225 g

I need help with this onehelp me please I have to show work too
adoni [48]
Correct, because $.6 per ounce works for all of the number of ounces. Times 0.6 for all of the number of ounces on the left side (5,10,15,20) to find the result (cost of detergent)

Quadrilateral QRST is a parallelogram. Solve for x (3x+5) (9x-17)
Naddika [18.5K]

Given:

Consider the below figure attached with this equation.

Quadrilateral QRST is a parallelogram.

To find:

The value of x.

Solution:

We know that the sum of two consecutive interior angles of a parallelogram is 180 degrees because they are supplementary angles.

In parallelogram QRST,

m\angle Q+m\angle T=180^\circ

(3x+5)^\circ+(9x-17)^\circ=180^\circ

(12x-12)^\circ=180^\circ

On comparing both sides, we get

12x-12=180

12x=180+12

12x=192

Divide both sides by 12.

x=\dfrac{192}{12}

x=16

Therefore, the value of x is 16.

Using coupons, you spend $120 grocery shopping. This is 80% of the total retail price of the groceries. How much would you spend
mr Goodwill [35]

Answer: The correct answer is $150.

Step-by-step explanation: If you did not use the coupons while shopping you would have spent $150. The method to calculate this is to divide the amount that you paid by the percentage that you paid.

The formula that you need to use is $120/.8 = $150.
