How to multiply 4 x 0.27

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

Hence the ratio of e : f would be:

e : f = 1.2f : f

e : f = 1.2 : 1

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.

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.

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

According to the presented question, m∢PSQ = 3y - 15 and m∢PRQ = 2y + 15, then m∢PSQ equals 97.

Supplementary angles are a pair of angles that always sum to 180 degrees. These two viewpoints are referred to as complements to one another. The English word "supplementary" is derived from the Latin words "Supplere" and "Plere," which respectively mean "supply" and "fill." As a result, the term "supplementary" designates something that is added to complete a task.

In this lesson, we will study about supplementary angles and how they can be applied to various geometry problems. As we explore supplementary angles, we'll discover how they differ from complimentary angles.

We know that the measure of an angle is supplementary to its adjacent angle. That means that the measure of an angle and its adjacent angle add up to 180 degrees.

Given that m∢PSQ = 3y - 15 and m∢PRQ = 2y + 15, we can set up the equation:

m∢PSQ + m∢PRQ = 180

Plug in the values for the angles:

(3y - 15) + (2y + 15) = 180

Simplifying, we get:

5y = 180

Now we can find the value of y by dividing both sides by 5:

y = 36

Therefore, m∢PSQ = 3y - 15 = 3(36) - 15 = 97

So, the measure of angle PSQ is 97 degrees.

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)

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

Rules of division indicate,

Thus, the answer to 36÷13 does NOT represent a number greater than 36.

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 general, a train going 50 mph will take about 1 1/2 miles or 8,000 feet to stop safely. This is because a train moving at 50 mph is traveling at about 75 feet per second, and it takes a significant distance to slow down a heavy object moving at such a high speed.
