Principal, P = $ 300,000

Rate, R =  20%

Time, T = 30 years

The down payment would be 300,000 x 20% = $60,000.

The principal for the home loan after the down payment would be 300,000 - 60,000 = $240,000.

The total amount owed to the bank including principal and interest would be 240,000 + 232200 = $462200.

To calculate the monthly payment for a 30 year mortgage, you would use the formula:

(principal + interest) / (number of months in 30 years)

which would be ($462200) / (360 months) = $1283.33

To calculate the total monthly cost including another 300 per month for taxes and 150 per month for insurance, you would add the mortgage payment to the additional costs:

1283.33 + 300 + 150 = $1733.33.

The distance between two places cab be found using distance formula if you know the coordinates of the places.

The distance formula is a mathematical equation that can be used to find the distance between two points in a two-dimensional or three-dimensional space. The formula is as follows:

Distance = √((x₂ - x₁)² + (y₂ - y₁)² + (z₂ - z₁)²)

Where x₁, y₁, and z₁ are the coordinates of the first point and x₂, y₂, and z₂ are the coordinates of the second point. The formula is based on the Pythagorean theorem, which states that the square of the distance between two points is equal to the sum of the squares of the differences in their coordinates.

For example, if you have the coordinates of two places on a map, you can use the distance formula to calculate the distance between them. Let's say the coordinates of place A are (x₁, y₁) = (4, 5) and the coordinates of place B are (x₂, y₂) = (9, 12). The distance between place A and place B would be:

Distance = √((x₂ - x₁)² + (y₂ - y₁)²)

= √((9 - 4)² + (12 - 5)²)

= √(5² + 7²)

= √(25 + 49)

= √(74)

= 8.6

The first waiter with $60 tips share $15 dollar to the second waiter and the second waiter with $80 share $20 to the first waiter.

As per data given is two different earned from tips, there will be two different amount of share from each. For a waiter that earned $60 from tip, the share will be:

First waiter share = tips earned x 1/4

First waiter share = $60 x 1/4

First waiter share = $60 x 0.25

First waiter share = $15

The share of the second waiter that earned $80 from tip will be:

Second waiter share = tips earned x 1/4

Triangle ABC and triangle DEF are not congruent.

What does a math congruent mean?

Congruent refers to things that are exactly the same size and shape. Even if we flip, turn, or rotate the forms, the shape and size should remain the same.

The measure of angle A and angle D are both 40 degrees, but the measure of angle B and angle F are not equal. The measure of angle B is 20 degrees, while the measure of angle F is 120 degrees.

In a triangle, the sum of all three angles is 180 degrees. So in triangle ABC, the measure of angle C is 180-40-20 = 120 degrees.

In triangle DEF, the measure of angle E is 180-40-120 = 20 degrees.

Therefore, angle B and angle E are not congruent, so the triangles are not congruent.

In order for two triangles to be congruent, they must have corresponding sides and angles of the same measure. Since the measure of angle B and angle E are not equal, then triangle ABC and triangle DEF are not congruent.

To solve nth problems we use the formula stated as  aₙ = a + (n – 1)d.

A series in which the differences between each pair of following terms are the same is known as an arithmetic progression (AP). A formula for the nth term of the AP could be derived from this kind of progression. Because it follows a pattern where each number is acquired by adding 4 to the preceding term, the sequence 2, 6, 10, 14,... is an example of an arithmetic progression (AP). In this series, the nth term equals 4n-2. By changing the nth term to n=1,2,3,..., the sequence's terms can be obtained. i.e.,

First term when n = 1 is 4n-2 = 4. (1)

-2 = 4-2=2

second term = 4n-2 = 4 when n = 2 (2)

-2 = 8-2=6

The third term is 4n-2 = 4 for n = 3. (3)

y = [tex]\dfrac{ x + 8}{x^2 + 3x + 2}[/tex]  is the rational function  that has a horizontal asymptote of y = 0.

When the denominator of a polynomial has a degree of at least 1, it is said to be a rational function. Or to put it another way, the denominator must contain a variable.

When p(x) and q(x) are polynomials and q(x) ≠ 0, the general form of a rational function is p(x)/q(x).

Asymptotes are lines that the function graph approaches but never crosses. Both the x and y axes are asymptotes in the parent function f(x)=1x. The parent function's graph will approach the asymptotes steadily but never actually touch them.

If the degree of the denominator > degree of the numerator, there is a horizontal asymptote at y = 0.

Here, only y = [tex]\dfrac{ x + 8}{x^2 + 3x + 2}[/tex] has the degree of the denominator > degree of the numerator.  

Thus, y = [tex]\dfrac{ x + 8}{x^2 + 3x + 2}[/tex]  is the rational function  that has a horizontal asymptote of y = 0.

The surface area of the rectangular prism, as a function of x, is given by:

A = 2*( (x - 2)*(x + 4) + (x + 4)*(2x + 1) + (x - 2)*(2x + 1))

For a prism whose dimensions are X, Y, and Z, the surface area is:

A = 2*(X*Y + X*Z + Z*Y)

In this case we know that the dimensions of the rectangular prism are:

X = x - 2

Y  =x + 4

Z = 2x + 1

Replacing that on the surface area equation we will get:

A = 2*( (x - 2)*(x + 4) + (x + 4)*(2x + 1) + (x - 2)*(2x + 1))

In other words, corresponding angles are any pair of angles which occur on the same side of the parallel lines which are cut by another line. As shown in the given figure, a transversal line intersects two parallel lines which produces eight angles. It contains four pairs of corresponding angles, i.e., 1 and 5, 2 and 6, 3 and 7, and 4, and 8. Corresponding angles are congruent angles.

The ratio of e:f from 2 different squares are 1.2:1.

From the case, we have 2 squares that:

Square E side = e

Square F side = f

Area of E = (1 + 44%) Area of F

Using the area of square formula, we know that:

Area of square = side x side

Area of square = side²

Area of E = e x e

Area of E = e²

Area of F = f x f

Area of F = f²

We will compare the area of both squares:

Area of E = (1 + 44%)Area of F

e² = (1 + 44%) f²

e² = 1.44 f²

√e² = √(1.44 f²)

e = 1.2 f

Answer:

Yes, an acute angle is an angle that measures less than 90 degrees.

Step-by-step explanation:

The main difference between a true solution and a colloidal solution is the particle size of the dispersed substance. In a true solution, the particles are so small that they cannot be seen with the human eye, while in a colloidal solution, the particles are intermediate in size and are visible under microscope.

A true solution is a homogeneous mixture of two or more substances where one substance is completely dissolved in the other. The particles of the dissolved substance, called solute, are so small that they cannot be seen with the human eye and are evenly distributed throughout the solution. A true solution is transparent, and the particles of the dissolved substance do not scatter light, thus not visible under a microscope. Examples of true solutions are sugar dissolved in water, and salt dissolved in water.

On the other hand, a colloidal solution is a type of mixture where one substance is dispersed throughout another substance in small particles that are not large enough to settle out but are large enough to scatter light. The particles of the dispersed substance, called the dispersed phase, are intermediate in size between those of a true solution and a suspension. The particles are visible under microscope, but not to the human eye, and the mixture is usually cloudy or opaque. Examples of colloidal solutions are milk, fog, and blood.
