Answer:
x=20 degrees
Step-by-step explanation:
So, lets recall some things.
First off, opposite angles are the same.
So this would make x equal 20.
But lets test this.
When you look at a X, or any other sort of two lines that cross each other, can you ever think of a time when one side is not the same as the other? No.
This is because when you change one angle, since the lines are crossed together, it will change the opposite angle. This change will always be constant as long as the two lines connect at the same point
So if you changed a 10 degree angle of two lines, so that it was 30, this would change for the other line.

Respuesta:
x = 20 grados
Explicación paso a paso:
Entonces, recordemos algunas cosas.
En primer lugar, los ángulos opuestos son iguales.
Entonces esto haría que x sea igual a 20.
Pero probemos esto.
Cuando miras una X, o cualquier otro tipo de dos líneas que se cruzan, ¿puedes pensar alguna vez en un momento en el que un lado no sea igual que el otro? No.
Esto se debe a que cuando cambia un ángulo, dado que las líneas se cruzan, cambiará el ángulo opuesto. Este cambio siempre será constante siempre que las dos líneas se conecten en el mismo punto
Entonces, si cambia un ángulo de 10 grados de dos líneas, de modo que sea 30, esto cambiaría para la otra línea.

-25-2x=3x
I know the answer to the problem but i´m not sure how to move the constant (-25) to the other side. When you move the constant to the right side the equation should be -2x=3x+25. How do you move a constant to the other side?

In this case I believe you would add 25 to both sides. The -25 +25 would cancel out and then +25 would be on the right.

Step-by-step explanation:
area = ½×(8.9+2.7)×4.2= ½×48.72=24.36m²
Find the surface area and round to the nearest hundredths place when necessary.
Answers
Answer:
Since your diameter is 8,
half of that is 4.
We are going to find the area now of both the bottom and the top.
4^4 = 16
16 x 3.14 = 50.24
Now we multiply by two since there are two circles (bottom and top) we only got one circle's area.
50.24 x 2 = 100.48
Now we need to find the round curved area.
In order to do that we need to find the circumference them multiply by the height:
2 x 3.14 x 4 = 25.12(circumference)
25.12 x 19Height) = 477.28
Now we need to add both the areas(surface area):
477.28 + 100.48 = 577.76 yard2 is your answer.
.25x + 0.05y = 9, x + y = 25
Answers
Answer:
x = -4
y = 29
Step-by-step explanation:
Let's take our two equations and turn the decimals into fractions for simplicity's sake. We get:
x/4 + 5y/100 = 9 x + y = 25
Simplifying a bit gives us:
x/4 + y/20 = 9 x + y = 25
Now, we will take the first equation and multiply it by 20 to get rid of the fractions. We get:
5x + y = 9
We will rearrange numbers to give us an answer to y that we can substitute in. we get:
y = 9 - 5x
Then, we will plug this into our second equation giving us:
x + 9 - 5x = 25
Combining like terms and subtracting 9 from both sides gives us:
-4x = 16
Dividing by -4 gives us:
x = -4
Then, we can substitute this into our second equation giving us:
-4 + y = 25
We will add 4 to both sides giving us:
y = 29

The lines represented by the equations y= -1/3x+2and 5y+15x=-40
Answers
The two lines are neither parallel nor perpendicular to each other.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that the two equations of the lines are y= -1/3x+2 and 5y+15x=-40.
y= -1/3x+2
5y+15x=-40.
5y = -15x - 40
y =-3x - 40/3
Here the slopes of the lines are,
m₁= -1 / 3
m₂ = -3
For the lines to be parallel the slopes should be equal and for the lines to be perpendicular the slopes should be inverse and reciprocal.
Here the slopes are neither equal nor have the inverse reciprocal.

Alex draws a diagonal in a rectangle that is 4 inches long and 3 inches wide. What is the area of one of two triangles that are formed?
Answers
Answer:
3.975 square inches
Step-by-step explanation:
Step 1
We find the length of the triangle
We solve using Pythagoras Theorem
Diagonal² = Length² + Width²
Diagonal = 4 inches
Width = 3 inches
Length² = Diagonal² - Width²
Length = √Diagonal² - Width²
Length = √4² - 3²
Length = √16 - 9
Length = √(7)
Length = 2.6457513111 inches
Length = 2.65 inches
Step 2
Area of Triangle = 1/2 × Base × Height
Base = Length = 2.65 inches
Height = Width = 3 inches
=1/2 × 2.65 inches × 3 inches
= 3.975 square inches
Therefore, the area of one of the triangles that are formed is 3.975 square inches

c) The distribution of salaries is skewed to the right.
We know that a histogram is a graph in which the x-axis is a quantitative variable split into bins, and the y-axis is the frequency.
For given distribution of salaries for individuals, the Y-axis would have the frequency i.e., the numbers of people in each salary category.
And x-axis would have income, because this is out quantitative variable of interest.
consider the following histogram.
We can observe that the graph of distribution of salaries is skewed to the right, because most income data are positively skewed. There would be a substantial number of individuals at or near the lowest salary level, but some people make a tremendously high salary.

Step-by-step explanation:
1 )
A.P : - 15, - 7, 1, ...
Here,
a = - 15
d = - 7 - ( - 15 )
= - 7 + 15
d = 8
65th term is t65.
t65 = a + ( 65 - 1 )d
= a + 64 d
= - 15 + 64 ( 8 )
= - 15 + 512
t65 = 597
Therefore,
65th term = 597
2 )
A.P = 3, 10, 17, 24, ...
Here,
a = 3
d = 10 - 3 = 7
50th term is t50.
t50 = a + ( 50 - 1 )d
= a + 49d
= 3 + 49 ( 7 )
= 3 + 343
t50 = 346
Therefore,
50th term = 346
Answer:
65ᵗʰ Term of the sequence is 479
50ᵗʰ Term of the sequence is 346
Step-by-step explanation:
1.)Here,
First Term = a₁ = 3
Second Term = a₂ = 10
Third Term = a₃ = 17
Now,
Common Difference (d)
d = a₂ - a₁ = (-7) - (-15) = -7 + 15 = 8
d = a₃ - a₂ = 1 - (-7) = 1 + 7 = 8
Here, Common Difference is same everywhere
Now, For 65ᵗʰ term, n = 65
aₙ = a + (n - 1)d
a₆₅ = (-15) + (65 - 1) × 8
a₆₅ = (-15) + 64 × 8
a₆₅ = (-15) + 512
a₆₅ = 479
Thus, 65ᵗʰ Term of the sequence is 479
2.)Here,
First Term = a₁ = -15
Second Term = a₂ = -7
Third Term = a₃ = 1
Now,
Common Difference (d)
d = a₂ - a₁ = 10 - 3 = 7
d = a₃ - a₂ = 17 - 10 = 7
Here, Common Difference is same everywhere
Now, For 50ᵗʰ term, n = 50
aₙ = a + (n - 1)d
a₅₀ = 3 + (50 - 1) × 7
a₅₀ = 3 + 49 × 7
a₅₀ = 3 + 343
a₅₀ = 346
Thus, 50ᵗʰ Term of the sequence is 346

Find the derivative of the function. y = arctan √[(1 − x) /(1 + x)]
y' = ?
Answers
The derivative of the function y = [tex]tan^{-1}[/tex] √[(1 - x)/(1 + x)] is given by
y' = -1/[(1 + x)²× √[(1 - x)/(1 + x)]].
To find the derivative, we use the chain rule. The derivative of the outermost function, arctan, is
1/[1 + (√[(1 - x)/(1 + x)])²], and the derivative of the innermost function, the square root, is
-1/2×(1 - x)/[[tex](1+x)^{3/2}[/tex])]. Multiplying these two derivatives together gives us the final result.
1/[1 + (√[(1 - x)/(1 + x)])²]×-1/2×(1 - x)/[[tex](1+x)^{3/2}[/tex])]
=-1/[(1 + x)²× √[(1 - x)/(1 + x)]].
When we take the derivative of a function, we are essentially finding the slope of the tangent line of a function at a given point. This derivative will tell us the rate at which y changes with respect to x. The derivative of the function y = [tex]tan^{-1}[/tex] √[(1 - x)/(1 + x)] is a negative value, which means that as x increases, y decreases. Therefore, this function has a negative slope.

If a baseball player gets a hit 42% of his at bats, what is the probability that the baseball player will get a hit in 4 at bats in a row?
Answers
Answer:
Probability of one hit in 4 in a row = 42% = 42/100
Probability of 4 hits in a row = 3.1% = 31/1000
Step-by-step explanation:
Since all throws are independent events;
If 4 hits in a row
You can make a fraction and square by the amount of hits so if the questions asking 4/4 hits see below or change to the amount of hits you need.
(42/100)^4 = 0.03111696
This is 3.1%
42/100^1 stays 42% = 42/`100
42/100^2 becomes 17.64% = 441/2500
42/100^3 becomes 7.4% = 37/500
The probability that the baseball player will get a hit in 4 at-bats in a row is 0.0313 or about 3.13%.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
Assuming each at bat is independent of the others.
The probability of getting a hit in any one at bat = 0.42
The probability of not getting a hit = 0.58.
The probability of getting a hit in 4 at bats in a row is the product of the probabilities of getting a hit in each of the 4 at bats.
= P(hit in 4 at bats)
= 0.42 × 0.42 × 0.42 × 0.42
= 0.0313
Therefore,
The probability that the baseball player will get a hit in 4 at-bats in a row is 0.0313 or about 3.13%.

By what percentage did the total number of students on the honor roll increase
Answers
The total number of students on the honor roll increased by 20%.
Given that, 75 boys and 50 girls on the honor roll
=> boys increased by 24% = 75*24/100 = 18
So, the number of boys is increased by 18.
=> girls increased by 14% = 50*14/100 = 7
So, the number of girls is increased by 7.
After the increment, the number of boys and girls on the honor roll is 93 and 57, respectively.
Thus, the total number of students increased = 18+7 = 25
Therefore, the percentage increment in total = 25 / 125 * 100 = 20%
Hence, The total number of students on the honor roll increased by 20%.
