How do you find the distance between two places?.
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

lena is sharing 36 muffins equally with some friends. She uses division to determine how many people can have a share if each person gets a particular number of muffins. For example, 36÷9=4
means that if each person gets 9 muffins, 4 people can have muffins. Here are some other calculations:
36÷9=4
36÷3=12

Answer: Disagree.
Step-by-step explanation:
Dividend = 36
Divisor = 13
36 (Dividend) ÷ 13 (Divisor) = 2 (Quotient)
Remainder = 10
Rules of division indicate,
Quotient < Dividend
Here too, 2 < 36

Square E has sides of length e cm.
Square F has sides of length f cm.
The area of square E is 44% greater than the area of square F.
Work out the ratio e:f
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

A. 100 ft B. 1/2 miles C. 1 1/2 miles D. 5 miles
It takes a train going 50 mph approximately 11/2 miles to stop safely.
The distance a train takes to come to a stop can be determined by several factors, including the speed of the train, the weight of the train, the condition of the brakes and the track, and the reaction time of the engineer.
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. It's important to note that this is an estimation, and the actual stopping distance may vary depending on the specific conditions.

You want to buy a house for 300,000 and pay 20% down. How much is your down payment? Calculate the principal for the home loan after the down payment. The bank tells you the total interest for the loan will be $232200 over 30 years. Calculate the total amount owed to the bank including principal and interest. Calculate the monthly payment for a 30 year mortgage. Calculate the total monthly cost including another 300 per month for taxes and 150 per month for insurance.
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 surface area of the rectangular prism, as a function of x, is given by:

What is the surface area of the prism?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:

How do you solve nth problems?.
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)

According to the presented question, m∢PSQ = 3y - 15 and m∢PRQ = 2y + 15, then m∢PSQ equals 97.
The term "supplementary angles" means what exactly?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.

Substituting the values in the equation , we get
( -1/4 ) x m₂ = -1
m₂ = 4
So , the slope of the line perpendicular to the line A is m₂ = 4
Hence , the slope of the line is m₂ = 4

If the graph doesn't go through the origin (0,0), the relationship is not a proportional one.
What you mean by proportional graph?A graph that represents a proportional relationship between y and x will have a straight line that passes through the point of origin (0, 0). The graph shown therefore doesn't represent a graph where y is directly proportional to x.For a graph representing a relationship where y is directly proportional to x, (y = kx), the line of the graph passes through the point of origin (0, 0).When y is directly proportional to x, the quantity of y changes along with the quantity of x.The graph shown has a line that doesn't pass through the point of origin (0, 0), so it is not a proportional graph and does not represent a relationship where y is directly proportional to x.Therefore, a graph that represents a proportional relationship between y and x will have a straight line that passes through the point of origin (0, 0). The graph shown therefore doesn't represent a graph where y is directly proportional to x.

2. In triangle ABC, the measure of angle A is 40°, and the measure of angle B
is 20°. In triangle DEF, the measure of angle D is 40°, and the measure of
angle F is 120°. Is AABC-ADEF? Explain how you know. Include any
calculations that might help you.
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.
