Answer:21 cm.

Step-by-step explanation:

Para encontrar la longitud del lado de un cuadrado con un área de 441 cm², podemos usar la fórmula del área de un cuadrado.

El área de un cuadrado se calcula elevando al cuadrado la longitud de uno de sus lados, es decir, A = L², donde A es el área y L es la longitud del lado.

Dado que el área del cuadrado es 441 cm², podemos escribir la ecuación:

441 = L²

Para encontrar L, podemos tomar la raíz cuadrada de ambos lados de la ecuación:

√441 = √L²

21 = L

Por lo tanto, la longitud del lado de un cuadrado con un área de 441 cm² es de 21 cm.

Benny (B) would win the election using the plurality method.

To determine the winner using the plurality method, we need to calculate the total number of first-place votes for each candidate and see which candidate receives the most votes.

According to the given preference schedule, the number of first-place votes for each candidate is as follows:

Abe (A): 1st - 20 votes, 3rd - 2 votes (from the 2nd preference of voter 1)

Benny (B): 1st - 19 votes, 2nd - 5 votes

Chloe (C): 1st - 5 votes, 2nd - 19 votes, 3rd - 3 votes (from the 1st and 2nd preferences of voter 1)

Now, let's calculate the total number of first-place votes for each candidate:

Abe (A): 20 + 2 = 22 votes

Benny (B): 19 + 5 = 24 votes

Chloe (C): 5 + 0 + 3 = 8 votes

Based on the plurality method, the candidate with the highest number of first-place votes wins.

In this case, Benny (B) received the most first-place votes with a total of 24 votes.

Therefore, Benny (B) would win the election using the plurality method.

The amount of cars you need to break even is 5.

To determine the number of cars you need to break even, we can set up an equation where the revenue equals the total cost.

Let's denote the number of cars as x.

Revenue = Number of cars × Price per wash

= x × $10

Total cost = Cost per car × Number of cars + One-time cost

= $3x + $35

To break even, the revenue should be equal to the total cost:

x × $10 = $3x + $35

Now, let's solve this equation to find the value of x:

10x = 3x + 35

Subtract 3x from both sides:

10x - 3x = 3x + 35 - 3x

7x = 35

Divide both sides by 7:

x = 35 / 7

x = 5

The two areas where buckeyes and monarchs have the same proportion are areas A and B.

Based on the information given, we can determine the two areas where the number of buckeye butterflies and the number of monarch butterflies are in the same proportion.

Comparing the data in the table, we can see that the ratio of buckeye butterflies to monarch butterflies is consistent in areas A and B.

In area A, there are 15 buckeye butterflies and 27 monarch butterflies, which simplifies to a ratio of 5:9.

In area B, there are 27 buckeye butterflies and 48 monarch butterflies, which also simplifies to a ratio of 5:9.

Therefore, the two areas where buckeyes and monarchs have the same proportion are areas A and B.

Hello!

13/14 x 26/49

= 169/343

Answer:

3.33 minutes

Step-by-step explanation:

h = rt - 4.9t^2

In this case, the rocket is launched upward, so the initial velocity (r) is positive 1960 m/s. The rocket will fall to the ground when the height (h) becomes zero.

0 = 1960t - 4.9t^2

To solve this quadratic equation, we can set it equal to zero and use the quadratic formula:

4.9t^2 - 1960t = 0

Using the quadratic formula:

t = (-b ± √(b^2 - 4ac)) / (2a)

Here, a = 4.9, b = -1960, and c = 0. Plugging in these values:

t = (-(-1960) ± √((-1960)^2 - 4 * 4.9 * 0)) / (2 * 4.9)

Simplifying further:

t = (1960 ± √(3841600)) / 9.8

t = (1960 ± 1960) / 9.8

t = 1960 / 9.8 = 200

So, the rocket will fall to the ground after 200 seconds. To convert this to minutes, divide by 60:

200 seconds / 60 = 3.33 minutes (approximately)

Therefore, the rocket will fall to the ground after approximately 3.33 minutes.

Answer:

three more couches are needed to increase the truckload to one ton.

Step-by-step explanation:

First, let's calculate the weight of the five couches:

5 couches * 250 pounds/couch = 1250 poundsSince one ton is equal to 2000 pounds, we can subtract the weight of the couches from one ton to find out how much additional weight is needed:

2000 pounds - 1250 pounds = 750 poundsEach couch weighs 250 pounds, so we can divide the additional weight needed by the weight of each couch to determine how many more couches are needed:

750 pounds / 250 pounds/couch = 3 couches Therefore, three more couches are needed to increase the truckload to one ton.

The GPA of the student who earned a "C" in Trigonometry, a "B" in American History, an "A" in Botany, and a "B" in Microbiology is 3.

To calculate the GPA, we need to assign point values to each grade and then calculate the weighted average.

Given:

Trigonometry (C) = 2 points

American History (B) = 3 points

Botany (A) = 4 points

Microbiology (B) = 3 points

To calculate the GPA, we'll sum the total points earned and divide by the total number of courses:

Total Points = 2 + 3 + 4 + 3 = 12

Total Courses = 4

GPA = Total Points / Total Courses = 12 / 4 = 3

Therefore, the GPA of the student who earned a "C" in Trigonometry, a "B" in American History, an "A" in Botany, and a "B" in Microbiology is 3.

The sum or difference that is modeled by the algebra tiles is option D. (-x² + 2x + 3) + (-x² - 2x - 1) = -2x² + 2

Algebra tiles are physical manipulatives used to teach and visualize algebraic concepts. They consist of small, square-shaped tiles that represent different algebraic expressions or values. The tiles come in different colors to represent positive and negative numbers, variables, and constant terms.

Here are the common types of algebra tiles:

1. Unit Tiles: These tiles represent the number one. They are typically square-shaped and are often the base tiles used to build other expressions.

2. Variable Tiles: These tiles represent variables or unknowns. They are usually rectangular in shape and may have different colors to distinguish between different variables.

3. Positive and Negative Tiles: Tiles of different colors, usually red and blue, are used to represent positive and negative values. These tiles can be combined or separated to illustrate operations like addition and subtraction.

4. Area/Rectangle Tiles: These tiles are used to represent quadratic expressions or algebraic expressions involving products or factoring. They are rectangular in shape and can be arranged to model multiplication, factoring, or area representation of polynomials.

Answer:

1. Group B has the lowest age range out of both groups. Group B has at least 18 students under 16 and Group A has ages from 5 through 30.

2. Group A has more of a variability of ages because it is more scrambled than Group B. Group B had more students that had ages that were all close to each other.

3. I think it's best to use the median because it measures the age above which is found. If we use the mean, it will only be calculated by adding all numbers together and then dividing the sum of the numbers by the number of numbers.

x - 3(9+7)x-(-3x) equals -43x, which is the answer we get after applying the order of operations.

To simplify this expression, we need to use the order of operations, which is PEMDAS (parentheses, exponents, multiplication and division, and addition and subtraction). We can simplify the expression step-by-step, following the rules of PEMDAS.
First, we need to simplify the parentheses, which contain an addition operation. We have:
x - 3(9 + 7)x - (-3x)
= x - 3(16)x + 3x   (remember that -(-3x) is the same as +3x)
= x - 48x + 3x     (multiplying 3 by 16 gives us 48)
= -44x + x
= -43x

Therefore, the expression x - 3(9+7)x-(-3x) simplifies to -43x.
In summary, x - 3(9+7)x-(-3x) equals -43x, which is the answer we get after applying the order of operations. Remember to follow the rules of PEMDAS carefully, and take your time simplifying each part of the expression.

The graph that represents the motion of Joe on his bike is: Graph D

A speed time graph is defined as a graph that shows the motion of an object against time. They can also be referred to as even a velocity-time graph.

In a speed-time graph, we note that the speed is always plotted on the vertical axis and time is always plotted on the horizontal

Now, since Joe started at a constant rate, then it means that the line will be horizontal.

When he picks up the pace, the graph line will ascend upwards and when he maintains the peak speed, it means that the graph line remains horizontal.
