For a triangle with base= 2 cm and perimeter= 10 cm, total area of the plastic triangles on the spinner is=18 square centimeters or 18 cm²
Let us assume that the two sides that are not the base of the triangle are x each.
Therefore, the perimeter of the triangle is: x + x + 2
Now,
2x + 2 = 10 cm
=> x = 4 cm
Thus, we have a right triangle with sides 2 cm, 4 cm, and a hypotenuse of =√(2^2 + 4^2)
= √20
= 2√5.
The area of a triangle is= 1/2×(base)×(height).
For the plastic triangles, the base is 2 cm and the height is 2√5. Therefore, the area is given by:
=1/2(2)(2√5)
= 2√5 square centimeters.
The spinner has four plastic triangles, so the total area is:
=4(2√5)
= 8√5 square centimeters.
Now, we need to get an approximate value for the area using a calculator or by estimating √5 as 2.24:
8(2.24) ≈ 17.92 square centimeters, which is closest to 18.
Therefore, the answer is: 18 square centimeters or 18 cm².

In an auditorium, there are 18 seats in the first row and 25 seats in the second row. The number of seats in a row, n, continues to increase by 7 with each additional row. Write an iterative rule, an, to model the sequence formed by the number of seats in each row.
The iterative rule to model the sequence of the number of seats in each row in the auditorium is given by an = 18 + 7(n - 1), where n represents the row number.
To determine the iterative rule for the sequence, we observe that the number of seats in each row increases by 7 with each additional row. We start with the first row, which has 18 seats. In the second row, there are 18 seats from the first row plus an additional 7 seats, resulting in a total of 25 seats.
To generalize this pattern, we can express the number of seats in the nth row as follows:
an = 18 + 7(n - 1).
In this formula, n represents the row number, and (n - 1) indicates the number of rows that follow the first row. By multiplying the number of additional rows by 7 and adding it to the initial number of seats in the first row (18), we can determine the number of seats in any given row in the auditorium using this iterative rule.

A rule of thumb used by nutritionist is that to lose one LB of body fat, you need to burn three, 500 cal about what you take in. If you burn 450 more calories than you take in each day, how long will it take to lose one LB? What about 10 LB?
If you consistently burn 450 more calories than you consume each day, it will take approximately 8 days to lose one pound of body fat. To lose 10 pounds, it would take around 80 days.
To lose one pound of body fat, you need to create a calorie deficit of 3,500 calories (500 calories x 7 days). If you burn 450 more calories than you consume each day, you would have a daily deficit of 450 calories. Dividing 3,500 calories by 450 calories (deficit per day) gives us approximately 7.8 days. This means it would take about 8 days to lose one pound of body fat.
To calculate the time it would take to lose 10 pounds, we multiply the time taken to lose one pound (8 days) by the desired weight loss. Therefore, 8 days x 10 pounds equals 80 days. So, if you consistently maintain a daily deficit of 450 calories, it would take around 80 days to lose 10 pounds of body fat. It's important to note that individual results may vary due to factors such as metabolism, body composition, and activity level.

Given the following diagram, let us assume that AB=DE and AD=DC. Also, suzette started a proof to show that BC=EF. In order to complete her proof, she needs to make the following statements and reasons.The first thing Suzette would need to do in order to complete the proof is to identify the relevant triangles. In this case, the relevant triangles are triangle ABD and triangle CDE. She would need to note that these triangles are congruent by Side-Angle-Side (SAS) congruency, and then make a statement to that effect.
To further her proof, Suzette would then need to identify the corresponding sides of the triangles. This would be side AB for triangle ABD, and side DE for triangle CDE. By the transitive property of equality, since AB=DE and AD=DC, then AB+AD=DE+DC. This is the same as BD=CE. Suzette can now make a statement that BD=CE as a reason for BC=EF.

Solve. 2. 5m 24 = 62 m = 1. 52 m = 15. 2 m = 34. 4 I don't know.
The equation is satisfied, confirming that m = 15.2 is the correct solution.
To solve the equation 2.5m + 24 = 62, we need to isolate the variable m.
First, let's subtract 24 from both sides of the equation:
2.5m + 24 - 24 = 62 - 24
This simplifies to:
2.5m = 38
To isolate m, we divide both sides of the equation by 2.5:
(2.5m) / 2.5 = 38 / 2.5
This gives us:
m = 15.2
Therefore, the solution to the equation 2.5m + 24 = 62 is m = 15.2.
In the given options:
m = 1.52 is not the solution since it doesn't satisfy the equation.
m = 15.2 is the correct solution, as we obtained above.
m = 34.4 is not the solution since it also doesn't satisfy the equation.
So, the correct answer is m = 15.2.
It's important to check our solution by substituting the value of m back into the original equation:
2.5(15.2) + 24 = 62
38 + 24 = 62
62 = 62
The equation is satisfied, confirming that m = 15.2 is the correct solution.

a circle of diameter 60cm is cut out of a square of a side 80cm,
calculate the shaded area
The shaded area can be calculated by subtracting the area of the circle from the area of the square. So the shaded area is approximately is 3574 cm².
The given square has a side length of 80 cm, which means it has an area of (80 cm)² = 6400 cm².
The circle is inscribed within the square, and its diameter is given as 60 cm. The radius of the circle is half the diameter, so the radius is 60 cm / 2 = 30 cm. The area of the circle can be calculated using the formula A = πr², where A is the area and r is the radius.
Substituting the values, the area of the circle is A = π(30 cm)² = 900π cm².
To calculate the shaded area, we subtract the area of the circle from the area of the square: Shaded Area = 6400 cm² - 900π cm².
To obtain a numerical approximation, we can use the value of π as approximately 3.14: Shaded Area ≈ 6400 cm² - 900(3.14) cm².
Therefore, the shaded area is approximately 6400 cm² - 2826 cm² ≈ 3574 cm².

A guy wire is attached to an antenna tower that is perpendicular to the ground. The wire is attached 100 feet up the tower and makes an angle of 55 degrees with the ground. What is the length of the wire?
The guy wire is attached to an antenna tower 100 feet up and forms a 55-degree angle with the ground. We need to determine the length of the wire.
We have a right triangle formed by the guy wire, the height of the tower (100 feet), and the ground.
Let's denote the length of the guy wire as "w."
Using trigonometric ratios, we can use the sine function to relate the angle and the sides of the right triangle:
sin(angle) = opposite/hypotenuse
In this case, the opposite side is the height of the tower (100 feet), and the hypotenuse is the length of the guy wire (w).
sin(55 degrees) = 100/w
To solve for w, we can rearrange the equation:
w = 100/sin(55 degrees)
Using a calculator, we can calculate the value of sin(55 degrees) ≈ 0.8192.
Substituting this value into the equation, we have:
w ≈ 100/0.8192 ≈ 122.16
Therefore, the length of the guy wire is approximately 122.16 feet.
Answer: The length of the wire is approximately 122.16 feet.

The distance between the pair of parallel lines y = -x and y = -x - 4 is 4 units.
To find the distance between two parallel lines, we can calculate the perpendicular distance from any point on one line to the other line. In this case, we can choose a point on the line y = -x, such as (0, 0), and calculate the perpendicular distance to the line y = -x - 4.
The formula to find the perpendicular distance between two parallel lines Ax + By + C1 = 0 and Ax + By + C2 = 0 is given by:
d = |C2 - C1| / sqrt(A^2 + B^2)
For the given lines y = -x and y = -x - 4, the equations can be rewritten as -x - y = 0 and -x - y - 4 = 0, respectively. Comparing the coefficients, we have A = -1, B = -1, C1 = 0, and C2 = -4.
Substituting these values into the formula, we get:
d = |-4 - 0| / sqrt((-1)^2 + (-1)^2) = 4 / sqrt(2) = 2sqrt(2) ≈ 2.83 units.

From these expressions, we can see that both 3a^2 and 3b^2 have a common factor of 3. This is because both expressions contain the factor 3.
However, when it comes to the variable terms, a^2 and b^2, we cannot directly determine their common factors based on the given information. The GCD of 3a^2 and 3b^2 will depend on the prime factors of a^2 and b^2, which are not provided in the question.
Therefore, without additional information about the prime factors of a^2 and b^2, we cannot determine the GCD of 3a^2 and 3b^2. The only common factor we can determine with the given information is 3, as both expressions have a factor of 3.

A directed line segment begins at F(-8, -2), ends at H(8, 6), and is divided in the ratio 8 to 2 by G.
What are the coordinates of G?
A- (4.8, 4.4)
B- (2.4, 5.2)
C- (2.2, 4.3)
D- None of the other answers are correct
E- (4.2, 3.4)
The correct coordinates of point G are option E: (4.2, 3.4).
To find the coordinates of point G, we need to divide the line segment FH in the ratio 8:2. This means that point G divides the line segment into 8 equal parts from F and 2 equal parts from H.
To determine the position of point G, we can use the concept of section formula. Let's denote the coordinates of G as (x, y). Using the section formula, we can calculate the coordinates of G as follows:
x = (8*x_G + 2*x_H)/(8 + 2)
y = (8*y_G + 2*y_H)/(8 + 2)
Plugging in the coordinates of F(-8, -2) and H(8, 6), we can solve for x and y:
x = (8*(-8) + 2*8)/(8 + 2) = 4.2
y = (8*(-2) + 2*6)/(8 + 2) = 3.4
Thus, the coordinates of G are approximately (4.2, 3.4).
Options A, B, C, and D are not correct coordinates based on the calculations above. Therefore, option E is the correct answer.

A. The Early Ages
B. The Roman Ages
C. The Black Ages
D. The Dark Ages
The time period from 500 A.D. to 1000 A.D. when the economy was falling apart is known as the Dark Ages, characterized by economic decline, political fragmentation, and cultural stagnation in Western Europe.
The correct term for the time period from 500 A.D. to 1000 A.D. when the economy was falling apart is "D. The Dark Ages." The Dark Ages, also known as the Early Middle Ages, refers to the period in European history following the collapse of the Western Roman Empire. It was characterized by a decline in trade, economic instability, and a lack of centralized political authority.
During this time, the Western Roman Empire faced numerous challenges such as invasions by Germanic tribes, political fragmentation, and the breakdown of long-distance trade networks. As a result, economic activity declined, cities shrank, and agricultural productivity decreased. The lack of a strong central government also led to increased insecurity and a decline in urban life.
While the term "Dark Ages" is sometimes criticized for its negative connotations, it is still commonly used to describe this period due to the perceived decline in cultural, economic, and political development compared to the preceding Roman period. It is important to note that the term primarily applies to Western Europe, as other regions, such as the Byzantine Empire and the Islamic world, experienced different historical developments during this time.

henry gets pic 'n mix when at the cinema and makes his bag up with 3 types of sweet. He picks 3 times as many smarties as cola bottles. He also picks twice as many marshmallows as smarties. What proportion of the bag of sweets are marshmallows
Marshmallows make up 2/7 or approximately 28.6% of the bag of sweets.
Let's denote the number of cola bottles as x. According to the information given, Henry picks three times as many smarties as cola bottles, so the number of smarties would be 3x. Additionally, he picks twice as many marshmallows as smarties, resulting in the number of marshmallows being 2(3x) = 6x.
To determine the proportion of marshmallows in the bag, we need to calculate the total number of sweets in the bag. The bag consists of cola bottles (x), smarties (3x), and marshmallows (6x), making a total of x + 3x + 6x = 10x sweets.
To find the proportion of marshmallows, we divide the number of marshmallows by the total number of sweets:
Proportion of marshmallows = (6x) / (10x) = 6/10 = 3/5 = 2/7.
Therefore, approximately 28.6% (2/7) of the bag of sweets are marshmallows.

what is the answer?
The ratio of the time taken by Brian and Colin to mark exam papers is 43 minutes to 1 hour. Hence, the simplified ratio of the time taken by Brian and Colin to mark exam papers is 43:60.
To express the times taken by Brian and Colin as a ratio, we need to convert their times to a common unit. Since both Brian and Colin's times are given in minutes and hours respectively, we need to convert Colin's time to minutes.
We know that 1 hour is equal to 60 minutes. Therefore, Colin's time of 1 hour can be expressed as 60 minutes.
Now, the ratio of Brian's time to Colin's time is 43 minutes to 60 minutes. However, we can simplify this ratio by dividing both numbers by their greatest common divisor, which is 1.
Dividing 43 and 60 by 1 gives us the simplified ratio of 43:60. This ratio cannot be further simplified since there is no common factor greater than 1 between 43 and 60.
Hence, the simplified ratio of the time taken by Brian and Colin to mark exam papers is 43:60.

if Z is the centroid of LMN, wz = 4, ZN = 14, and zy = 10, find each missing measure
Therefore, we have found that LY = 18 units, MY = 21.5 units, and ZY = 10 units.
Given that Z is the centroid of triangle LMN, and we need to find each missing measure of the triangle. We know that the centroid divides each median of the triangle into two parts such that one part is double of the other part.
Using the above property of centroid, we can find the value of LY as follows:
ZY = 10
(Given)
ZL = ZN + NY => NY = ZL - ZN (1)
Also, LY = 2 NY => NY = LY/2 (2)
From equation (1) and (2), we get:
LY/2 = ZL - ZN => LY/2 = (14 + 4)/2 => LY/2 = 9 => LY = 18
From the above derivation, we have found that LY = 18 units.
Now, we can find the value of MY using the same property of the centroid as follows:
ZX = 2 XM => XM = ZX/2 => XM = 14/2 = 7
Also,
LM = 2 LY => LM = 2 x 18 = 36
Therefore, MN = LM
Now, MN = MY + YN => 36 = MY + YN => YN = 36 - MY
Therefore, MY = XM + YN => MY = 7 + (36 - MY) => MY + MY = 43 => 2 MY = 43 => MY = 43/2
Thus, MY = 21.5 units.

Tim uses 9 liters of water (w) to water 24 flower pots (f). If this relationship is proportional, what equation represents this relationship? *
The relationship between the amount of water (w) and the number of flower pots (f) is proportional.
In a proportional relationship, the ratio between the two quantities remains constant. In this case, the amount of water used (w) is directly proportional to the number of flower pots (f) that need to be watered. To find the equation that represents this relationship, we can set up a proportion using the given information.
Let's assume that x represents the constant ratio between the amount of water used and the number of flower pots. The equation can be written as:
w/f = x
Substituting the given values, we have:
9/24 = x
Simplifying the equation, we find:
x = 9/24
To find the final equation, we can multiply both sides of the equation by 24:
24x = 9
Therefore, the equation that represents the proportional relationship between the amount of water (w) and the number of flower pots (f) is 24x = 9. This equation shows that for every 24 flower pots, 9 liters of water are required.
