Step-by-step explanation:
Use the triangle bisector theorem:
"The angle bisector of a triangle divides the opposite side into two parts proportional to the other two sides of the triangle."
so 12 is to 16 as x is to 20
12/ 16 = x/20
20 * 12/16 = x = 15 units
Answer:
x = 15
Step-by-step explanation:
the segment inside the triangle is an angle bisector and divides the side opposite the angle into segments that are proportional to the other two sides , that is
\(\frac{12}{16}\) = \(\frac{x}{20}\) ( cross- multiply )
16x = 12 × 20 = 240 ( divide both sides by 16 )

if abcd is dilated by a factor of 1/3 the coordinate of A would be?
Answers
Answer:
A' = (-1, -1)
Step-by-step explanation:
Rule for the dilation of any point A(x, y) about the origin by a factor of k is given by the rule,
A(x, y) → A'(kx, ky)
From the graph attached,
Coordinates of point A are (-3, -3) and it is dilated by a scale factor of \(\frac{1}{3}\) about the origin then the coordinates of the image point A' will be,
A(-3, -3) → \(A'(-3\times \frac{1}{3},-3\times \frac{1}{3})\)
→ A'(-1. -1)
Therefore, coordinates of A' = (-1, -1) is the answer.

Answers
The rate at which the water level is rising when the water level is 5 cm is;
dh/dt = 1.6 cm/s
What is a PYRAMID?A structure with triangle outside surfaces that converge to a single step at the summit is referred to as a pyramid (from Greek: pyrams)]. This shape is roughly a pyramid in the geometric sense. A pyramid foundation might be triangular, quadrilateral, or any other type of polygon. A pyramid therefore has at least three triangular exterior surfaces (at least four faces including the base). A typical variation is the square pyramid, which has a square base and four triangular exterior surfaces.Because a pyramid is built with the pyramidion at the top and the remainder of the weight closer to the ground[3], less material will be pressing down from above. Early civilizations could build stable structures thanks to this weight distribution.Acc to our question-
length of square side; s = 4 cmheight of pyramid; h = 8 cmvolumetric rate; dV/dt = 30 cm³/sSince the base is square shaped and we know that area of a square = s², then we can say that;Volume of pyramid = ¹/₃s²hThe pyramid has a height of 8 cm and length of its' square base side is 8 cm.Now, regardless of the water height, the surface of the water will always be square shaped. This implies that the ratio of the height to the top side of square will always be the same. Thus, we can say that; s = 4/8 h = h/2Thus, Volume is;V = ¹/₃ × (h/2)² × hV = ¹/₃ × h³/4V = h³/12dV/dt = (3h²/4) dh/dtPlugging in the relevant values gives;30 = (3 × 5²/4) dh/d120 = 75 dh/dtdh/dt = 120/75dh/dt = 1.6 cm/sHence,The rate at which the water level is rising when the water level is 5 cm is; dh/dt = 1.6 cm/s

In essence, percentages are fractions with 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100). A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If need to calculate a percentage of a number, should divide it by its entirety and then multiply it by 100.
since radio buy at 3/4 th of marked price
let us assume 100 be the marked price
then he buy it in 75
and sold at 20 % profit = 120

About the circle relation C on the set of real numbers:
To determine if circle (C) is reflexive, we need to examine if for every real number x, x C x holds true. By definition of C, this means that for every real number x, x^2 + x^2 = 1.
Now, let's simplify this equation: x^2 + x^2 = 2x^2, so we get 2x^2 = 1. To satisfy this equation, x^2 must equal 1/2. However, there is no real number x for which x^2 = 1/2.
As we cannot find an example of x such that (x, x^2 + x^2) = (x, 1), we conclude that since this does not equal 1, C is not reflexive.

Tom is playing a board game.
He has rolled a six nine times in a row.
What's the probability that his 10th roll will not be a six?
금
Answers
Answer:
Step-by-step explanation:
Hello!
If you consider the 6-sided dice to be balanced, then each result has the same probability of occurrence: P(1)=P(2)=P(3)=P(4)=P(5)=P(6)= \(\frac{1}{6}\)
And each time Tom rolls the dice is independent of the other times, this means that you can disregard all previous rolls and calculate the 10nth time as if it is the 1st one.
Be the event A: "Tom rolled the dice for the 10nth time and obtained a 6"
The probability of A occurring will be P(A)= 1/6
On the other hand, the complement of "A" will be \(A^c\): "Tom rolled the dice for the 10nth time and didn't obtain a 6"
This means he could obtain a 1 or a 2 or a 3 or a 4 or a 5
You can calculate the probability pf this event by adding the probability of obtaining each value P(\(A^c\))= P(1)+P(2)+P(3)+P(4)+P(5)= 1/6*5= 5/6
Or by subtracting the probability of A to the total probability of the sample space:
P(\(A^c\))= 1 - P(A)= 1 - 1/6= 5/6

Compare the second line with the first line. How much more money does Diego have after 1 hour of babysitting? 2 hours? 5 hours? x hours?
Answers
The second line should be compared to the first line to determine how much more money Diego has after a certain number of hours of babysitting. The amount of money earned by Diego per hour should be taken into account to calculate the difference in earnings after 1, 2, 5, or x hours of babysitting.
To determine how much more money Diego has after a certain number of hours of babysitting, we need to compare the earnings per hour mentioned in the first and second lines. Let's denote the amount of money earned by Diego per hour as "p" in the first line and "q" in the second line.
After 1 hour of babysitting, Diego would have earned an additional "q - p" amount of money compared to the first line. After 2 hours of babysitting, Diego would have earned a total of "(2 * q) - (2 * p)" more money compared to the first line.
After 5 hours of babysitting, Diego would have earned a total of "(5 * q) - (5 * p)" more money compared to the first line. If we want to calculate the difference in earnings after x hours of babysitting, the formula would be "(x * q) - (x * p)".
In summary, to determine how much more money Diego has after a certain number of hours of babysitting, we compare the earnings per hour mentioned in the first and second lines. The difference in earnings can be calculated by subtracting the earnings per hour in the first line (p) from the earnings per hour in the second line (q), and then multiplying that difference by the number of hours of babysitting.

Galaxy A has a cosmological redshift in its spectrum of z = 0.01 indicating it is moving away from us at 3000 km/s. Galaxy B has z = 0.08. a) How fast is Galaxy B moving away from us?
Answers
Galaxy B is moving away from us at a speed of 24,000 km/s.
The speed at which Galaxy B is moving away from us would be 24,000 km/s. Here's how we arrived at this conclusion:
Given: Galaxy A has a cosmological redshift in its spectrum of z = 0.01 indicating it is moving away from us at 3000 km/s.
Galaxy B has z = 0.08.We know that the redshift z is directly proportional to the speed at which the galaxy is moving away from us.
In other words, z ∝ v, where z is the redshift, and v is the speed.
Therefore, we can write:z₁/v₁ = z₂/v₂where z₁ and v₁ are the redshift and speed of Galaxy A, and z₂ and v₂ are the redshift and speed of Galaxy B.
Rearranging the formula, we get:v₂ = (z₂/z₁) x v₁
Substituting the values of z₁, v₁, and z₂ into the formula, we get:v₂ = (0.08/0.01) x 3000 km/sv₂ = 24,000 km/s
Therefore, Galaxy B is moving away from us at a speed of 24,000 km/s.

Step-by-step explanation: When line AB and CD intersect at point E, angle AEC equals BED so you set them equal to each other and find what x is. 5x -20 = x + 50, solving for x, which gives you 17.5. Finding x will tell you what AEC and BED by plugging it in which is 67.5. Angle BED and BEC are supplementary angles which adds up to 180 degrees. So to find angle CEB, subtract 67.5 from 180 and you get 112.5 degrees.

A tank has a height of 10 feet. The area of the horizontal cross section of the tank at height h feet is given by the function A, where A(h) is measured in square feet. The function A is continuous and decreases as h increases. Selected values for A(h) are given in the table above. (a) Use a left Riemann sum with the three subintervals indicated by the data in the table to approximate the
volume of the tank. Indicate units of measure.
Answers
To approximate the volume of the tank using a left Riemann sum, we can use the provided data in the table. The left Riemann sum is obtained by multiplying the width of each subinterval by the corresponding height value of the function A.
Given that the height of the tank is 10 feet and the function A is decreasing as the height increases, we can divide the height interval into three subintervals: [0, 2], [2, 6], and [6, 10].
Using the left endpoint of each subinterval, we can calculate the approximate volume as follows:
Volume ≈ (width of subinterval 1) * (A(0)) + (width of subinterval 2) * (A(2)) + (width of subinterval 3) * (A(6))
Let's assume the width of each subinterval is 2 feet based on the given data. Using the values from the table, we can substitute the corresponding height values:
Volume ≈ (2) * (8) + (2) * (6) + (2) * (4)
