ONo candidate wins using the plurality method.

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.

In a college, some courses contribute more towards an overall GPA than other courses. For example, a science class is worth 4 points; mathematics is worth 3 points; history is worth 2 points; and English is worth 3 points. The values of the grade letters are as follows, A= 4, B=3, C=2, D=1, F=0. What is the GPA of a student who made a “C” in Trigonometry, a “B” in American History, an “A” in Botany, and a “B” in Microbiology?
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.
How to find the valuesTo 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.

Y=x-5
x+y=-1
What is the solution to the system of equations
Answer:
x = 2
y = -3
Step-by-step explanation:
y = x - 5
x + y = -1
To solve the given system of equations, we can use the method of substitution.
That is, you can replace y with ( x - 5 ).
x + y = -1
x + (x - 5 ) = -1
x + x - 5 = -1
Combine like terms.
2x - 5 = - 1
Add 5 to both sides.
2x = - 1 + 5
2x = 4
Divide both sides by 2.
x = 2
And now let us find the value of y by replacing x with 2.
y = x - 5
y = 2 - 5
y = -3

What is x-3(9+7)x-(-3x)
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.

Rewrite the following in the form log(c). 2log(5)
The expression 2log(5) can be rewritten as log(25) in the form log(c), representing the Logarithm to the base 10 that yields the value 25.
The expression 2log(5) in the form log(c), we can use the logarithmic property that states:
nlog(b) = log(b^n)
Applying this property, we can rewrite 2log(5) as:
2log(5) = log(5^2)
Simplifying further, we have:
2log(5) = log(25)
Therefore, the expression 2log(5) can be written in the form log(c) as log(25).
The logarithmic function log(c) represents the exponent to which a given base must be raised to obtain the value c. In this case, log(25) represents the exponent to which the base 10 must be raised to obtain the value 25.
In summary, the expression 2log(5) can be rewritten as log(25) in the form log(c), representing the logarithm to the base 10 that yields the value 25.

A rocket is launched upward with an initial velocity of 1960 m/s. After how many minutes does it fall to the ground? (in meter the formula h=rt-4.9t^2 is used
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.

¿Cual es la longitud del lado de un cuadrado de ´área 441 cm2 ?
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.

Use the law of cosines to find one angle and the law of sines to find a second angle. Then use either rule or other rules from geometry to calculate the third angle. Angles may be calculated in radians or degrees. All sides are 7.5 inches.
The value of all three angles, A , B and C is 60°
Using the cosine Rule :All sides , a,b, and c are 7.5 inches
From Cosine Rule :
CosA = (b² + c² - a²)/(2bc)
CosA = (7.5² + 7.5² - 7.5²)/(2 × 7.5 × 7.5)
CosA = 56.25/112.5
CosA = 0.5
A =
[tex] {cos}^{ - 1} (0.5) = 60[/tex]
Using Sine RuleFrom Sine Rule a/sinA = b/sinB
7.5/Sin60° = 7.5/SinB
cross multiply
7.5SinB = 7.5(Sin60°)
sinB= 6.495/7.5
SinB = 0.866
B =
[tex] {sin}^{ - 1} (0.866) = 60[/tex]
Using the Sum of Triangle RuleA + B + C = 180
60 + 60 + C = 180
C = 180 - 120
C = 60°
Therefore , all three angles A,B and C are 60° each.

The length of the variable are as follows;
x = 27.4 units
y = 12.7 units
How to find the variables in the tangent, secant and chord?When two secants intersect outside a circle, the circle divides the secants into segments that are proportional with each other.
Therefore,
5(x + 5) = 6(21 + 6)
5x + 25 = 126 + 36
5x + 25 = 162
5x = 162 - 25
5x = 137
x = 137 / 5
x = 27.4 units
Let's find variable y as follows;
If a secant and a tangent are drawn to a circle from the same external point, the product of the length of the secant and its external segment equals the square of the tangent segment.
Therefore,
y² = (21 + 6)6
y² = 27 × 6

This ultimately implies that, the dimension (size) or side lengths of the dilated geometric object would be stretched or shrunk depending on the scale factor that is applied.
In this context, we can reasonably infer and logically deduce that both figure A and figure C are congruent to figure E because they all share a common center of dilation.
