The mass of the ball is 278.1 g, the material used to make the ball must be brass which having density of 8.6 g/cm³.

To determine the material used to make the ball, we need to first calculate the volume of the ball.

The volume of a sphere with radius r is given by:

V = (4/3) * π * r^3

Plugging in the given values, we get:

V = (4/3) * π * (2 cm)^3

= (4/3) * π * 8 cm^3

= (4/3) * 8π cm^3

= 32π cm^3

We can then use the density of each material (given in g/cm³) to calculate the mass of the ball if it were made of that material:

Copper: 8.3 g/cm³ * 32π cm³ = 266.4 g

Brass: 8.6 g/cm³ * 32π cm³ = 275.2 g

Iron: 7.8 g/cm³ * 32π cm³ = 250.4 g

Since the mass of the ball is 278.1 g, the material used to make the ball must be brass.

The decibel level of the noise from a motorcycle with intensity 10⁻² watts per square inch (W/in²) is equal to 50 dB.

In Science, sound intensity can be defined as a measure of the power of a sound wave per unit area. This ultimately implies that, sound intensity is a quantity that is typically be used for measuring the energy of sound and its unit of measurement is Watts per square meter (W/m²) or .

Mathematically, sound intensity level or decibel level can be calculated by using this formula:

[tex]\beta = 10 log(\frac{I}{I_{ref}} )[/tex]

Note: The reference value of sound intensity is equal to 1.0 × 10⁻¹² watts per square inch (W/in²).

Since the intensity of the noise from this motorcycle is 10⁻² W/in², the decibel level (in dB) would be calculated as follows:

Decibel level, β = 10 × log(10⁻²/10⁻¹²)

Decibel level, β = 10 × log(10¹⁰)

Decibel level, β = 10 × 10

Using the elimination method, the solution to the system of equations is as follows:

x = 19 / 13  and y = - 74 / 13

System of equations can be solved using different methods such as the elimination method, substitution method, and graphical method.

Let's use the elimination method to solve the system of equations as follows:

The elimination method is the process of eliminating one of the variables in the system of equations using the addition or subtraction methods in conjunction with the multiplication or division of coefficients of the variables.

Therefore,

4x - 7y = 10

3x + 2y = -7

multiply equation(ii) by 3.5

4x - 7y = 10

10.5x - 7y = 24.5

subtract equation(i) from equation(ii)

6.5x = 14.5

x = 14.5 / 6.5

x =  145 / 65

x = 19 / 13

Let's find y

3(19 / 13) + 2y = -7

57 / 13 + 2y = -7

2y = - 7 - 57 / 13

2y = -91 - 57  / 13

2y = - 148 / 13

cross multiply

26y = - 148

y = - 148 / 26

y = -  74 / 13

The system of linear equations have no solution

The system of linear equations is the set of two or more linear equations involving the same variables. Here, linear equations can be defined as the equations of the first order, i.e., the highest power of the variable is 1. Linear equations can have one variable, two variables, or three variables. Thus, we can write linear equations with n number of variables.

In the problem, given the system of linear equations are

y = 4/5x - 3 ...eq(i)

y = 4/5x + 1 ...eq(ii)

a) Since there are two unknown variables(x, y) the number of solutions expected is 2.

b)

From equation (i)

y = 4/5x - 3

Put eq(i) into equ(ii)

4/5x - 3 = 4/5x + 1

0 = 4

There's no solution for x and y

In the calculation, there's no solution for both x and y because the variables in both equation are equal to one another and hence cancel out.

Answer:

68 feet tall

Step-by-step explanation:

Imagine the shadows for both the tree and the person are set up like right triangles. The length of their shadows are the bases of the triangles, while the actual heights of the tree and person are the heights of the triangle. We can set up proportions since  "height of the person" divided by " their shadow's length" should equal "height of tree" divided by "tree shadow length".

Set up a proportion of the person's high height relative to their shadow's length (which is 6/4.5). Set this equation equal to the tree's proportion (which is x/51).

Solve for x.

[tex]\frac{6}{4.5} = \frac{x}{51}\\Isolate x by multiply 51 to both sides\\\\(306/4.5)=x\\68=x[/tex]

The proportion is solved and the height of the tree is A = 68 feet

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion be represented as A

Now , the value of A is

Now , we can set up the following proportion:

Height of tree / length of tree's shadow = height of person / length of person's shadow

On simplifying , we get

A / 51 = 6 / 4.5

Now we can solve for A by cross-multiplying and simplifying:

A = 51 x 6 / 4.5

A = 68 feet

Therefore, the tree is 68 feet tall

Hence , the proportion is solved

The equation to model the cost 'y' based on the number of movies streamed 'x' would be 14 = 2x and 20 = 6x.

What is a linear equation in one variable?

The linear equation in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

For the first case:

If 2 movies are streamed, the cost is $14 per month

So the cost = number of movies * cost per movie

            y = 2*x

           14 = 2x

For the second case:

If 6 movies are streamed, the cost is $20 per month

So the cost = number of movies * cost per movie

            y = 6*x

           20 = 6x

Hence the equation to model the cost 'y' based on the number of movies streamed 'x' would be 14 = 2x and 20 = 6x.

The value of the shortest of the three sides of the triangle is 13 cm.

A triangle is a polygon with threes sides. The perimeter of a triangle is the sum of the whole three sides.

The lengths of the three sides of a triangle (in centimetres) are consecutive odd integers. The perimeter is 45 cm.

The shortest side of the three sides can be calculated as follows:

let

the first side = x

second side = x + 2

third side = x + 4

Hence,

perimeter = x + x + 2 + x + 4

45 = 3x + 6

45 - 6 = 3x

3x = 39

divide both sides by 3

x = 39 / 3

x = 13

Therefore,

shortest side = 13 cm

The exact value of the logarithmic expression 12 · ㏒₃ [z⁷ / (y⁵ · t²)] is equivalent by logarithm properties to -711 / 5.

In this question we must determine the exact value of a logarithmic expression by means of logarithm properties, which are described below:

Logarithm of a product

㏒ (a · b) = ㏒ a + ㏒ b

Logarithm of a division

㏒ (a / b) = ㏒ a - ㏒ b

Logarithm of a power

㏒ aⁿ = n · ㏒ a

The intersection region of every solution in the system of inequalities is the system's solution. Inequality y≤x2 should be graphed first. y=x2 serves as the related equation.

Example

Graph the inequalities and solve the system:

y≤x−2y>−3x+5

Inequality yx2 should be graphed first. y=x2 serves as the related equation.

The border line is solid due to the inequality's, which is not a rigid one.

The inequality yx2 should be substituted in for a point that is not on the line, such as (0,0).

0≤0−20≤−2

It's untrue. The point (0,0) is therefore not part of the solution. Subtract from the line's lower half.
