A cube of metal has a mass of 0.317 kg and measures 3.01 cm on a side. Calculate the density and identify the metal.

Answers

Answer 1

Answer: The volume of the cube is given by V = s^3, where s is the length of each side. Therefore, the volume of the cube is:

V = (3.01 cm)^3 = 27.28 cm^3

The density of the cube is given by the mass divided by the volume:

density = mass / volume = 0.317 kg / 27.28 cm^3

We need to convert cm^3 to kg/m^3 to get the units right:

1 cm^3 = 10^-6 m^3

1 kg/m^3 = 10^6 kg/cm^3

So, we have:

density = 0.317 kg / (27.28 cm^3 x 10^-6 m^3/cm^3)

density = 11,603 kg/m^3

Now, we need to identify the metal. The density of the cube can be compared to the densities of different metals to determine the identity. Here are the densities of some common metals:

Aluminum: 2,700 kg/m^3Copper: 8,960 kg/m^3Gold: 19,320 kg/m^3Iron: 7,870 kg/m^3Lead: 11,340 kg/m^3Silver: 10,490 kg/m^3

Since the density of the cube is closest to the density of lead, we can identify the metal as lead.

For division, we don't divide if there is a fraction, so we move the decimal place over to the right for both the numbers

Then you long divide as normal:

solve each equation by substituting. y=-3x+5

not different problems they are in the same problem

Answers

Answer:

(1, 2 )

Step-by-step explanation:

Given the 2 equations

y = - 3x + 5 → (1)

5x - 4y = - 3 → (2)

Substitute y = - 3x + 5 into (2)

5x - 4(- 3x + 5) = - 3 ← distribute and simplify left side

5x + 12x - 20 = - 3

17x - 20 = - 3 ( add 20 to both sides )

17x = 17 ( divide both sides by 17 )

x = 1

Substitute x = 1 into (1) for corresponding value of y

y = - 3(1) + 5 = - 3 + 5 = 2

solution is (1, 2 )

Answer:

x = 1 and y = 2

Step-by-step explanation:

y + 3x = 5 -------------> (1)

-4y + 5x = -3 -------------> (2)

(1) * 4

=> 4y + 12x = 20 --------> (3)

(3) + (2)

=> 0y + 17x = 17

=> 17x = 17

by dividing both sides by 17

=> x = 1

by putting x = 1 into (1)

=> y + 3*1 = 5

=> y + 3 = 5

=> y = 5 - 3

=> y = 2
