Step-by-step explanation:

because area of a rectangle is L × B

or length × width

since the length is expanded by x

10.5 (12x)

Answer:

Option C

Step-by-step explanation:

The original length of the room = 12 feet

After expansion, the new length = [tex](12 + x)[/tex] feet

Width of the room = 10[tex]\frac{1}{2}[/tex] feet = 10.5 feet

Area of a rectangle = Length × Width

The shape of the living room is a rectangle.

∴Area of living room = [tex](12 + x)[/tex] feet × [tex](10.5)[/tex] feet  
                                     [tex]= 10.5(12 + x)[/tex] square feet

Expand the brackets or parenthesis by applying the Distributive Law:

                                  [tex]= (12)(10.5) + (10.5)(x)[/tex] square feet

                                  = [tex](125 + 10x)[/tex] square feet

∴Option C

The volume of the rectangular prism will be (4x - 3)(x + 1)( x+2) cubic feet.

The volume of the rectangular prism is defined as the space in three-dimension covered by the rectangular prism having the sides Length, Width, and Height.

Given that the length, width, and height of the rectangular prism are,

The volume of the rectangular prism will be calculated as,

Volume = Length x width x Height

The total weight of the liquid in the tank which is hemisphere in shape is 16,415 pounds.

The density and mass are related to each other with the formula -

Density = mass/volume

So, we have the density. We need to calculate the volume of hemisphere which will be accomodating the liquid. Then we will find the mass.

Volume of hemisphere = 2/3πr³, where r represents radius.

Volume = 2/3×π×5³

Performing multiplication, division and taking cube

Volume = 261.8 feet³

Now, mass = density × volume

Mass = 62.7 × 261.8

The probability of getting three heads when tossing three coins is 1/2 x 1/2 x 1/2 = 1/8.

1/8

The probability of getting a head or a tail when flipping a coin is 1/2.  

Therefore, the probability of getting two heads when tossing two coins is 1/2 x 1/2 = 1/4.

The probability of getting three heads when tossing three coins is 1/2 x 1/2 x 1/2 = 1/8.

Since each person is tossing three coins, the probability that they both obtain the same number of heads is 1/8.

The probability of getting n heads when tossing n coins is 1/2^n. Therefore, the probability of getting the same number of heads when two people toss n coins is 1/2^n. This means that if two people each toss a coin, the probability that they both get heads is 1/4; if they each toss two coins, the probability that they both get two heads is 1/16; if they each toss three coins, the probability that they both get three heads is 1/64; and so on.

The solution to the given differential equation is y = e⁽ˣ³⁾⁽²⁸ˣ ⁺ ᶜ⁾, where C is a constant.

To solve the first-order linear differential equation of the form y' + p(x)y = q(x), where p(x) and q(x) are functions of x:

Find the integrating factor (IF) = e⁽∫ᵖ⁽ˣ⁾ᵈˣ⁾

Multiply both sides of the equation by the IF.

Apply the product rule to the left side and simplify the right side.

Integrate both sides with respect to x.

Solve for y.

Using this method, for the given equation:

y' - 3x²y = 28e⁽ˣ³⁾

Find the integrating factor (IF):

IF = e⁽∫ᵖ⁽ˣ⁾ᵈˣ⁾ = e⁽⁻³/¹ * ∫ˣ²ᵈˣ⁾ = e⁽⁻ˣ³⁾

Multiply both sides by the IF:

e⁽⁻ˣ³⁾y' - 3x²e⁽⁻ˣ³⁾y = 28

Apply the product rule to the left side and simplify the right side:

d/dx (e⁽⁻ˣ³⁾y) = 28

Integrate both sides with respect to x:

e⁽⁻ˣ³⁾)y = 28x + C, where C is the constant of integration.

Solve for y:

y = e⁽ˣ³⁾(28x + C)

Therefore, the solution to the given differential equation is y = e⁽ˣ³⁾(28x + C), where C is a constant.

Therefore, the temperature at midnight would be -12°C.

Temperature is a measure of the degree of hotness or coldness of a body or an environment. It is a physical quantity that expresses the amount of thermal energy in a substance or a system, typically measured using a thermometer in units such as Celsius (°C) or Fahrenheit (°F).

Step-by-step explanation:

o solve the compound inequality, we'll start by solving each inequality separately, and then find the intersection of their solutions.

For the first inequality: 8r - 3 ≥ 7r - 7

Adding 7r to both sides: 8r - 3 + 7r ≥ 7r - 7 + 7r

Combining like terms: 15r - 3 ≥ 14r

Subtracting 14r from both sides: 15r - 14r - 3 ≥ 0

Combining like terms: r - 3 ≥ 0

Adding 3 to both sides: r ≥ 3

For the second inequality: 2r + 4 ≤ r - 3

Subtracting 2r from both sides: 2r + 4 - 2r ≤ r - 3 - 2r

Combining like terms: 4 ≤ -r - 3

Adding r and 3 to both sides: 4 + r + 3 ≤ -r

Combining like terms: 7 ≤ -r

Multiplying both sides by -1: r ≤ -7

The solution to the compound inequality is the intersection of the solutions to each inequality, which is the range of r that satisfies both conditions. So, the solution is 3 ≤ r ≤ -7.

The actual distance between the basketball court and the pool is 37.5 feet

Distance refers to the amount of space between two objects or points. It is a measure of how far apart two things are from each other.

The scale of the model is 3 inches = 5 feet. This means that every 3 inches on the model represents 5 feet in actual size. We are given that the distance between the basketball court and the pool on the model is 22.5 inches. To find the actual distance between these areas, we need to use the scale.

We can start by setting up a proportion using the scale. We know that 3 inches on the model represents 5 feet in actual size. Therefore, we can say that:

3 inches / 5 feet = 22.5 inches / x

We are trying to solve for x, which represents the actual distance between the basketball court and the pool. To solve for x, we can cross-multiply and simplify the equation:

3 inches x x = 5 feet x 22.5 inches

3x = 112.5

The system of equations 5x+2y=-7 and 10x+4y= -14 has unique solution which is (-7/5,0).

In general, a system of linear equations can have one of three possible outcomes:

One unique solution (as in this case)

No solution (if the equations are inconsistent)

Infinitely many solutions (if the equations are dependent)

To solve this system of equations, we can use the method of elimination or substitution. Let's use the method of elimination, which involves adding or subtracting the equations to eliminate one variable.

First, we need to choose a variable to eliminate. Looking at the coefficients of x and y, we see that we can eliminate y by multiplying the first equation by -2 and adding it to the second equation:

-10x - 4y = 14

5x + 2y = -7

-5x = 7

Now we can solve for x:

-5x = 7

x = -7/5

We can substitute this value of x into one of the equations to solve for y. Let's use the first equation:

5x + 2y = -7

5(-7/5) + 2y = -7

-7 + 2y = -7

2y = 0

y = 0

Therefore, the solution to the system of equations is (x,y) = (-7/5,0).

This is called a unique solution, meaning there is only one possible solution for the system of equations.
