The numbers 1, 2, 3, and so on are called natural numbers
The numbers 1, 2, 3 and so on are commonly known as natural numbers. They are the most basic and fundamental type of numbers used in mathematics. Natural numbers are positive integers that are used for counting and measuring quantities.
They are called "natural" because they are the numbers that naturally occur when we count objects in the real world. The set of natural numbers is denoted by the symbol N and it is an infinite set that starts from 1 and continues infinitely. Natural numbers form the basis for other types of numbers, such as whole numbers, integers, rational numbers, and real numbers, and they are used in a wide range of mathematical applications.

Trinagle abc is similar to triangle def. The following ratios of corresponding sides are equal. 8/10 = 16/20 = 4x+6/4x+11
The value of x is 0. This means that [tex]8/10 = 16/20 = 4x+6/4x+11[/tex], so the corresponding sides of triangles abc and def have the same ratio.
The similarity of two triangles can be determined by the ratio of their corresponding sides. In the case of triangles abc and def, the ratio of corresponding sides is [tex]8/10 = 16/20 = 4x+6/4x+11[/tex].
To calculate the value of x, we can use the first two ratios and cross-multiply. With 8/10 = 16/20, we get 8*20=16*10, which simplifies to 160=160. Therefore, the first two ratios are equal.
To calculate the value of x using the third ratio, we can use the same method. With 4x+6/4x+11, we get ([tex]4x+6)*(4x+11)=4x^2+44x+66[/tex]. This simplifies to [tex]4x^2+44x+66=4x^2+44x+66[/tex], so the third ratio is also equal.

need the measure of angle ABC please
Answer:
∠ ABC = 38°
Step-by-step explanation:
given AB = DB then Δ ABD is isosceles with base angles congruent, that is
∠ BDA = ∠ BAD = 71°
the sum of the 3 angles in Δ ABD = 180° , so
∠ ABC + 71° + 71° = 180°
∠ ABC + 142° = 180° ( subtract 142° from both sides )
∠ ABC = 38°

Okay, I really need help, it’s a cooking need of help so I was making pasta, and I used a smaller top on a big pot (I know, I know..) and now it won’t come off, I’ve tried banging it around the edges, I put cold water on it, and I used dish soap to pry it open, nothing. I am not putting it in the freezer for it to cool off. Please help me!
Answer:
Dry your hands from the soap and try twisting the lid of the pan. This will cause it to start to turn. If you put it in the freezer it will be harder to take it off. My guess is by twisting the lid, you would be able to cause enough friction to take the lid off.
Step-by-step explanation:
If this doesn't work try tilting the lid and then lifting it
Answer:
Try soaking it in hot water. The pot only if possible. The top is smaller and if the pan expands it should loosen up

Answer:
The measure which changes the most is the mean and the new value is 84°
The correct answer option is option B
Step-by-step explanation:
How to calculate mean and median?
Given data set:
58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57
Median = (100 + 105) / 2
= 205/2
= 102.5°
Mean = (58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57) / 12
= 965 /12
= 80.4°
Range = Highest value - lowest value
= 105 - 57
= 48°
Interquartile range = Third quartile - First quatile
= 88.5° - 74°
= 14.5°
If 58° is changed to 101°
101, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57
Median = (100 + 105) / 2
= 205/2
= 102.5°
Mean = (101 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57) / 12
= 1008 /12
= 84°
Range = Highest value - lowest value
= 105 - 57
= 48°
First quartile = (71 + 77) / 2
= 148/2
= 74°
Third quartile = (95 + 82)/2
= 177/2
= 88.5°
Interquartile range = Third quartile - First quatile

find the cartesian equation
Answer:
[tex]y^2 = x^3 / 2^{3/2}[/tex] or [tex]y = x^{3/2} / 2^{3/4}[/tex]
Step-by-step explanation:
We can use the identity [tex]cos^3(t) = cos(t)*cos^2(t) and sin^3(t) = sin(t)*sin^2(t)[/tex] to rewrite the given parametric equations in terms of x and y:
[tex]x = 2cos(t)*cos^2(t) = 2x^2 - 2y^2[/tex]
[tex]y = 2sin(t)*sin^2(t) = 2xy^2[/tex]
Solving for y in terms of x, we get:
[tex]y = x^{3/2} / 2x^{3/4}[/tex]
Therefore, the cartesian equation of the curve is:
[tex]y = x^{3/2} / 2^{3/4}[/tex]

Find the distance, c, between (3, –4) and (–7, 1) on the coordinate plane. Round to the nearest tenth if necessary.
Answer:
c ≈ 11.2
Step-by-step explanation:
Using the distance formula, we have:
c = √[(x2 - x1)² + (y2 - y1)²]
c = √[(-7 - 3)² + (1 - (-4))²]
c = √[(-10)² + 5²]
c = √(100 + 25)
c = √125
c ≈ 11.2
Therefore, the distance between the two points is approximately 11.2 units.
[tex]\sqrt{(-7-3)^{2} + (1-(-4))^{2} } = \sqrt{(-10)^{2} + (5)^{2} } = \sqrt{100 + 25} \\[/tex]

ivy received a bank statement reposrting the recent changes to her account. the statement showed an overall increase in the account balance of $1,692.45. during the time shown on the statement, ivy was paid twice and withdrew a total of $1,876.23 to cover all her bills and expenses. how much (x) is each of ivay's paychecks? help me please
if Ivy received two Paychecks during the time period shown on the statement, each paycheck would be $1,784.34.
To find out how much each of Ivy's paychecks is, we need to subtract the amount she withdrew from her account from the overall increase in her account balance.
So, the calculation would be:
Overall increase in account balance - Total amount withdrawn = Total amount deposited
$1,692.45 - $1,876.23 = -$183.78
This means that Ivy actually spent more than she earned during the time period shown on the statement. Therefore, we cannot determine the amount of each of her paychecks with the given information.
However, if we assume that Ivy did not have any other income or expenses during the time period, we can use the following equation:
2x - $1,876.23 = $1,692.45
where x is the amount of each paycheck.
Simplifying the equation, we get:
2x = $3,568.68
x = $1,784.34
Therefore, if Ivy received two paychecks during the time period shown on the statement, each paycheck would be $1,784.34.

What is a Circle?
A circle is simply a round shape that has no corners or line segments. It is a closed curve shape in geometry. The points of circle are at a fixed distance from the center.
So now, to calculate the surface area of each jar, we need to find the area of the circular top and the area of the rectangular side.
The area of the circular top can be calculated using the formula for the area of a circle:
[tex]A=\pi r^{2}[/tex], where r is the radius of the circle.
The diameter of the jar is given as 7 cm, so the radius is half of that:
r = [tex]\frac{7}{2}[/tex] cm = 3.5 cm
Therefore, the area of the circular top is:
A_top = [tex]\pi r^2[/tex] = π[tex](3.5)^{2}[/tex] = 38.48 [tex]cm^{2}[/tex]
The area of the rectangular side can be calculated using the formula for the area of a rectangle:
A_side = base x height
The base of the rectangle is the circumference of the circular top, which can be calculated using the formula:
C = 2πr
C = 2π(3.5) = 22 cm
So the base of the rectangle is 22 cm, and the height is 11 cm, since that is the height of the jar.
Therefore, the area of the rectangular side is:
A_side = base x height = 22 cm x 11 cm = 242 [tex]cm^{2}[/tex]
To find the total surface area of each jar, we can add the area of the circular top and the area of the rectangular side:
A_total = A_top + A_side = 38.48 [tex]cm^{2}[/tex]+ 242 [tex]cm^{2}[/tex] = 280.48 [tex]cm^{2}[/tex]
For 12 jars, the total surface area of plastic wrap needed would be:
Total area = 12 x A_total = 12 x 280.48 [tex]cm^{2}[/tex] = 3365.76 [tex]cm^{2}[/tex]

Mr Cobb says that increasing something by 10% then decreasing it by 10% will just give you the original amount. Mr Pathuis says the new amount will be bigger. Mr Drake says the new amount will be smaller. Who is right and why?
Answer:
Mr Drake is right.
Step-by-step explanation:
Because you first decreased it by 10% of the ORIGINAL value.
You then increased it by 10% of the DECREASED value.
The percentages are the same percentages, but on different base amounts.
Simple example:
$100 decreased by 10% of $100 ($10) is $90.
$90 increased by 10% of $90 ($9) is $99.
Answer:
Mr Drake Is correct
Step-by-step explanation:
When you increase something by 10%, you multiply the original value by 1.1. When you decrease it by 10%, you multiply the increased value by 0.9. So the final amount is:
original value x 1.1 x 0.9 = 0.99 x original value
Therefore, the new amount will be slightly smaller than the original amount, and Mr. Drake is correct.

The couple asked the architect to add a square garden shed to the plans that she
drew. She added a square garden shed with coordinates (-2,8), (1,8), (1, 11), and
(-2, 11) to the plans. Discuss the following with a partner:
• How could you find the perimeter and area of the shed without graphing
the coordinates?
• How is this problem different from finding the perimeter and area of the
base of the house?
. Can you use the same strategy to solve both problems? Why or why not?
Answer:
To find the perimeter and area of the square garden shed without graphing the coordinates, you can use the distance formula to calculate the length of one side of the square. The distance formula is d = √((x2 - x1)^2 + (y2 - y1)^2), where (x1, y1) and (x2, y2) are the coordinates of two points. Using this formula with the coordinates of two adjacent corners of the square, such as (-2,8) and (1,8), we find that the length of one side of the square is 3 units. Since all sides of a square are equal in length, the perimeter is 4 times the length of one side, or 12 units. The area of a square is equal to the length of one side squared, so the area of the square garden shed is 9 square units.
This problem is different from finding the perimeter and area of the base of a house because it involves a square shape rather than a more complex shape. However, you can use similar strategies to solve both problems by calculating distances between points and using geometric formulas to find perimeter and area. The specific formulas used may vary depending on the shape of the base of the house.

We have 5 points in our situation, thus n = 4. We get the following results by plugging the provided points into the Lagrange polynomial formula:
[tex]L(x) = 1*(x-2)(x-3)(x-4)(x-5)/(-1123) + 2(x-1)(x-3)(x-4)(x-5)/(1123) + 4(x-1)(x-2)(x-4)(x-5)/(1123) + 4(x-1)(x-2)(x-4)(x-5)/(1123) (2123)+ 12(x-1)(x-2)(x-3)(x-4)/(432*1)[/tex]
When we simplify this expression, we get:
[tex]L(x) = x^3/3 - 3x^2/2 + 11x/6 - 1[/tex]
As a result, the equation of the curve passing through the given locations is:
[tex]y = x^3/3 - 3x^2/2 + 11x/6 - 1[/tex]

Given the pre-image ABCD and the image after a dilation, A'B'C'D', what is true about the polygons? Check all that apply.
The length AB is 2.
The length A'B' is 3.
The image is smaller than the pre-image.
The scale factor is Three-halves.
The scale factor is Two-thirds.
For the given dilation of the polygons the correct answer are The length AB is 2. The length A'B' is 3. The scale factor is Three-halves.
What is dilation?Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is a picture with the same shape as the original. Yet, there is a variation in the shape's size. The initial form should be stretched or contracted during a dilatation. The phrase "scale factor" describes this transition.
The distance formula for the coordinates is given as:
d(A, B) = |x1 - x2|
From the figure we observe that,
d(A, B) = |2 - 4|
d(A, B) = |-2|
d(A, B) = 2 units.
Hence, option A is correct.
Also, the length of A'B' is:
d(A', B') = |3 - 6| = |-3| = 3 units.
Hence, option B is correct.
The original shape is called the pre-image in a transformation (in this example, a dilation), and the transformed shape is called the image.
The third response is untrue since the picture is larger than the pre-image.
The scale factor of the images is:
2k = 3
k = 3/2.
Hence, option 4 is correct.
The last option is also false, as the scale factor is already determined.
Hence, for the given dilation of the polygons the correct answer are The length AB is 2. The length A'B' is 3. The scale factor is Three-halves.

The complete question is:
You are currently at point A on a circle, and you want to get to point B on the circle. You are trying to minimize the distance walked. You can either walk into the middle of the circle and then out of the circle, or you can walk around the edge of the circle. At what minimum distance between A and B do you walk in and then out of the circle in order to minimize the distance walked? State the answer as a % of total circumference.
To minimize the distance walked, and the minimum distance is 31.8% of the total circumference of the circle.
What is the minimum distance between A and B?
If we draw a line segment from A to B, it will intersect the circle at two points, C and D. We can find the distance AC and the distance BD by using the Pythagorean theorem.
Let r be the radius of the circle, and let x be the distance we walk in and then out of the circle.
Then, we have:
AC = √(r^2 - (x/2)^2)
BD = √(r^2 - (x/2)^2)
The total distance we walk is AC + BD + AB. Since AB is fixed, we want to minimize AC + BD.
AC + BD = 2√(r^2 - (x/2)^2)
To minimize this expression, we need to maximize the value inside the square root. That means, we need to set (x/2)^2 to be as small as possible.
In other words, we want x to be as large as possible.
The maximum value of x is the diameter of the circle, which is 2r.
If we walk in and out of the circle along the diameter, then AC and BD are both equal to r, and the total distance we walk is 2r + AB.
Therefore, the percentage of the total circumference that we walk in and out of the circle is:
2r / (2πr) * 100% = 100/π ≈ 31.8%
So, we need to walk in and out of the circle at two points that are opposite to each other, along a diameter, to minimize the distance walked, and the minimum distance is approximately 31.8% of the total circumference of the circle.

The reading on the thermometer is -20 degrees Fahrenheit and the temperature rises with 20 degrees Fahrenheit. What will be the new reading be?
As per the given temperature, the new reading is 0°F
The formula for converting Fahrenheit to Celsius is (°F - 32) x 5/9 = °C. We can use this formula to determine the new temperature in Celsius and then convert it back to Fahrenheit.
First we have to convert the initial temperature to Celsius
(-20°F - 32) x 5/9 = -28.89°C
Now we have to add 20 degrees Fahrenheit to the initial temperature
-20°F + 20°F = 0°F
And then we have to convert the new temperature to Celsius
(0°F - 32) x 5/9 = -17.78°C
When we convert the new temperature from Celsius back to Fahrenheit
-17.78°C x 9/5 + 32 = 0°F
Therefore, the new reading on the thermometer will be 0 degrees Fahrenheit, which indicates that the temperature has risen by 20 units on the Fahrenheit scale.
