Answer:
40
Step-by-step explanation:
Lets put the 3/4 at the beginning and expand this bracket :
3/4(x-4) = 27
3/4x - 3 = 27
Now we add 3 to both sides :
3/4x = 30
Now we times both sides by 4 :
3x = 120
Now we divide both sides by 3:
x = 40

Solve the proportion 60/n = 20/7
Answer:
The answer is zero there is no solving.
Step-by-step explanation:
cause you do
60/n=20/7, and then you move all the terms to the left
now it is: 60/2-(20/7)=0
the domain to this is n=0
add the numbers and variables together and get
60/n-(+20/7)=0 now get rid of the parentheses and now you got
60/n-20/7=0
and all that is 0

Each statement describes a transformation of the graph of y = ln x. Which statement correctly describes the graph of y = ln(x - 7) + 3?
The statement correctly describes the graph of y = ln(x - 7) + 3 is translated 3 units up as well as 7 units to the right.
what is the graph of logarithmic function?The graph of a logarithmic function has a vertical asymptote at x = 0. The graph of a logarithmic function will decrease from left to right
if 0 < b < 1. And if the base of the function is greater than 1, b > 1, then the graph will increase from left to right.
Given graph : y = ln(x), has a vertical and horizontal translation.
As we know, y = ln(x - h) + k | where h is the vertical shift, and k is the horizontal shift.
If ln(x - k), then the graph is translated right k units.If ln(x + k), then the graph is translated left k units.If ln(x) + h, then the graph is translated up h units.If ln(x) - h, then the graph is translated down h units.Therefore, comparing y = ln(x - 7) + 3 it with different function we can write the graph of y = ln(x - 7) + 3 is translated 3 units up as well as 7 units to the right.

Answer: 5 unitsReason:
Use the distance formula to find the distance from the origin (0,0) to the terminal point (-3, 4)
[tex](x_1,y_1) = (0,0) \text{ and } (x_2, y_2) = (-3,4)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(0-(-3))^2 + (0-4)^2}\\\\d = \sqrt{(0+3)^2 + (0-4)^2}\\\\d = \sqrt{(3)^2 + (-4)^2}\\\\d = \sqrt{9 + 16}\\\\d = \sqrt{25}\\\\d = 5\\\\[/tex]
The pythagorean theorem is a similarly related alternative path you can take.
This triangle is a 3-4-5 right triangle.
====================================================
Question 2.1.2
Answer: 1/5Reason:
r = distance from origin to terminal point
r = 5, calculated back in the previous problem above.
sin(alpha) = y/r = 4/5
cos(alpha) = x/r = -3/5
sin(alpha)+cos(alpha) = (4/5)+(-3/5) = 1/5
====================================================
Question 2.1.3
Answer: 1Reason:
Recall that tangent is the ratio of sine over cosine
tan = sin/cos
Therefore,
[tex]\tan(\alpha) *\frac{\cos(\alpha)}{\sin(\alpha)}\\\\\frac{\sin(\alpha)}{\cos(\alpha)}*\frac{\cos(\alpha)}{\sin(\alpha)}\\\\\frac{\sin(\alpha)*\cos(\alpha)}{\cos(\alpha)*\sin(\alpha)}\\\\1[/tex]
This assumes that neither sin(alpha) nor cos(alpha) are zero. Otherwise, we have a division by zero error.

rotation 180° about the origin
Answer:
The rule for a rotation by 180° about the origin is (x,y)→(−x,−y).
Step-by-step explanation:
The rotation of angle 180 degree about origin is described below.
Rotation 180° about the origin is a geometric transformation that involves rotating a figure or shape around the point (0,0),
Also known as the origin, by an angle of 180 degrees.
This means that every point on the shape is moved to an equal distance away from the origin but on the opposite side of the origin.
This transformation is a reflection where the shape is flipped along,
the x-axis or y-axis or both, depending on the shape's orientation.
The rotation 180° about the origin is a common transformation in various geometrical applications, such as computer graphics, engineering, and physics.
It is a simple transformation that can be easily represented and performed using matrices or complex numbers.
Therefore,
rotation 180° about the origin is a geometric transformation that is important in various applications and involves rotating a shape around the origin by an angle of 180 degrees, resulting in a reflection of the shape across the x or y-axis.

An airplane flight has 374 seats. The probability that a person who buys a ticket actually goes on that flight is about 85%. If the airline wants to fill all the seats on the flight, how many tickets should it sell?
Taking into account the definition of ratio and proportion, the airline should sell 440 tickets.
What is ratio and proportionThe ratio is the comparison of two quantities and is measured from the division of two values.
The relationship of equality that exists between two ratios, that is, between two comparisons between two determined quantities, is known as a proportion. So if [tex]\frac{a}{b}[/tex] corresponds to the ratio, then [tex]\frac{a}{b}[/tex] = [tex]\frac{c}{d}[/tex] equals a proportion.
Amount of tickets soldAn airplane flight has 374 seats. The probability that a person who buys a ticket actually goes on that flight is about 85%. The airline wants to fill all the seats (100%) on the flight.
This can be represented by the proportion:
[tex]\frac{374}{85}[/tex] = [tex]\frac{amount of tickets}{100}[/tex]
Solving:
amount of tickets= 100×[tex]\frac{374}{85}[/tex]
amount of tickets= 440
Finally, the airline should sell 440 tickets.

The angle measures of quadrilateral RSTU are shown.
m∠R = (2x)°
m∠S = (3x – 35)°
m∠T = (x + 35)°
The measure of angle U is unknown. Can quadrilateral RSTU be a parallelogram?
Yes, opposite angles R and T are congruent to each other if x = 35.
Yes, consecutive angles R and S are congruent to each other if x = 35.
No, if x = 35, all three given angles measure 70°. The fourth angle would measure 150°.
No, if x = 35, the three given angle measures make it impossible for the figure to be a quadrilateral.
The quadrilateral RSTU be a parallelogram if opposite angles R and T are congruent to each other if x = 35 option first is correct.
What is quadrilateral?It is defined as the four-sided polygon in geometry having four edges and four corners.
We have:
The angle measures of quadrilateral RSTU are shown.
m∠R = (2x)°
m∠S = (3x – 35)°
m∠T = (x + 35)°
If R and T are congruent:
2x = x + 35
x = 35 degree
Opposite angles R and T are congruent to each other if x = 35.
Thus, the quadrilateral RSTU be a parallelogram if opposite angles R and T are congruent to each other if x = 35 option first is correct.

How to calculate the area of trapezium B using the scale factor
Answer:
612.5 cm²
Step-by-step explanation:
The ratio of areas of similar figures is the square of the scale factor. The scale factor is the ratio of corresponding side lengths. Here, we must find the scale factor.
__
missing side of AThe only given side of trapezium B corresponds to an unknown side of trapezium A. We can find the length of that unknown side using the area formula.
A = 1/2(b1 +b2)h . . . . . parallel sides b1, b2; height h
98 cm² = 1/2(16 cm +b2)(7 cm) . . . . use known values
28 cm = 16 cm +b2 . . . . . . . . . . divide by 3.5 cm
b2 = 12 cm . . . . . . . . . . . . . . subtract 16 cm
The top side of trapezium A is 12 cm long.
scale factorNow we have the lengths of corresponding (top) sides, so we can find the scale factor. It is their ratio. We choose to express it as (size of B)/(size of A).,
k = (30 cm)/(12 cm) = 2.5
area of BThe area of trapezium B will be that of trapezium A multiplied by the square of the scale factor:
area B = (k²)(area A) = (2.5²)(area A)
area B = 6.25×98 cm² = 612.5 cm²
The area of trapezium B is 612.5 cm².
What is the area of this rectangle? (4 points)
A rectangle completely covered in square units is partitioned into two rectangles. The first rectangle has a measurement of four centimeters along the top and seven centimeters along the side. The second rectangle has a measurement of two centimeters along the top and seven centimeters along the side.
Answer:
42 cm
Step-by-step explanation:
The first rectangle has a length of 4 and a Width of 7. the second rectangle has a length of 2 and a width of 7.
The formula for area of a rectangle is A=l*w
SO,
Rectangle 1: A= L*W
A=4*7
A=28
Rectangle 2:
A=L*W
A=2*7
A=14
Now, add both areas since they are both part of one whole recatngle.
