Please answer me quickly!
Answer:
x = 35
Step-by-step explanation:
consider the triangle on the left
the left vertex and 36° are vertically opposite angles and are congruent.
the right vertex = 180° - (36 + 38)° = 180° - 74° = 106°
consider the triangle on the right
right vertex and 109° are a linear pair and sum to 180°
right vertex = 180° - 109° = 71°
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
106° is an exterior angle of the triangle on the right , that is
x + 71 = 106 ( subtract 71 from both sides )
x = 35
Point B ∈ AC so that AB : BC = 2:1. Point D ∈ AB so that AD : DB = 3:2. Find AD : DC.
Answer:
AD : DC is 2:3
Step-by-step explanation:
The parameters given are;
Point B ∈ AC
AB : BC = 2:1
Point D ∈ AB
AD : DB = 3:2
Therefore, whereby we sum the ratios, we have;
For AC
AB = 2/(2+1)×AC = 2/3×AC
BC = 1/3×AC
For AB
AD = 3/(3+2)×AB = 3/5×AB
DB = 2/5×AB
We are required to find AD:DC
Given that AD = 3/5×AB and AB = 2/3×AC
We have;
AD = 3/5×2/3×AC = 6/15 AC
DC = DB + BC = 2/5×AB + 1/3×AC = 2/5×2/3×AC + 1/3×AC = 4/15×AC + 1/3×AC
DC = 3/5×AC
AD : DC = 6/15 AC : 3/5×AC = 2:3.

profit%=15%
let Cost Price of an article be X
SP=CP+PROFIT %*CP
2300=X+15/100*X
2300=100X+15X/100
2300*100=115X
230000/115=X
2000=X
Therefore cost price of an article is Rs 2000.
find the area of the shaded region. the graph to the right depics iq scores of adults, and thoes scores are normally distrubuted with a mean of 100 and standard deviation of 15. The shade region is 125.
The area of the shaded region, representing the probability that an IQ score is greater than 125, is approximately 0.0475 or 4.75%.
To find the area of the shaded region, we need to determine the probability that an IQ score is greater than 125.
The given information states that IQ scores are normally distributed with a mean of 100 and a standard deviation of 15. We can use these parameters to calculate the z-score for the IQ score of 125.
The z-score formula is given by:
z = (x - μ) / σ
where x is the value (125 in this case), μ is the mean (100), and σ is the standard deviation (15).
Let's calculate the z-score:
z = (125 - 100) / 15
z = 25 / 15
z = 1.67
Now, we need to find the probability of obtaining a z-score greater than 1.67.
Using the standard normal distribution table, we can look up the area to the right of z = 1.67. The corresponding value is approximately 0.0475.
Therefore, the area of the shaded region, representing the probability that an IQ score is greater than 125, is approximately 0.0475 or 4.75%.

triangle ABC with verticales at A(-3,-3) B(3, 3) C(0, 3) is dilated to create triangle abc with verticles at a(-9, -9) B(9, 9) C(0,9)
We can conclude that the dilated triangle abc is similar to the original triangle ABC with a dilation factor of 3,
Dilation is a transformation that performs a proportional resize of a figure. It changes the size of the figure while maintaining its shape and orientation. To dilate triangle ABC to create triangle abc, we can multiply the coordinates of each vertex of ABC by a dilation factor of 3.
The coordinates of the vertices of the original triangle ABC are A(-3,-3), B(3,3), and C(0,3). Multiplying each coordinate by 3 gives the coordinates of the vertices of the dilated triangle abc : A(-9,-9), B(9,9), and C(0,9).
We can compare the two triangles to see how the dilation has affected them. The size of triangle abc is three times larger than that of triangle ABC. The shape and orientation of triangle abc are the same as that of triangle ABC. The vertices of the dilated triangle, abc, are located at three times the distance from the origin as the corresponding vertices of triangle ABC. That is why the coordinates of all vertices of triangle abc are three times the coordinates of the corresponding vertices of triangle ABC. since the triangle was resized proportionally and has the same shape and orientation.

There are five students standing in a line with their hats. Suddenly the wind picks up the hats and randomly assigns each hat to a student. What is the probability that no student will get his or her own hat
Answer:
The probability of a person getting their own hat is 1/5 or 20%.
Step-by-step explanation:
If each person has one hat the chances (the probability) of them getting their own hat would be 20%. The chances (the probability) of them getting a hat that belongs to one of the other four students would be 80%. Due to there being 5 hats each person owns 1 hat so there would be a 1 out of 5 chance of them getting their own hat.
: Which statements apply only to C3, C4, or CAM photosynthesis? Which statement applies to all three types of photosynthesis?

One or more answer choices are misplaced. The ribulose biphosphate in C3 plants picks up carbon directly from CO2 molecules. Oxygen can also attach to ribulose bisphosphate, but it cannot be used to construct sugar molecules. Ribulose bisphosphate's affinity for binding oxygen is most noticeable when stomata close during times of intense heat and drought. What adaptations do C4 and CAM plants have that prevent the Calvin cycle from shutting down in periods of dryness?
The statements that only apply to C3, C4, and CAM photosynthesis are:
1. C3, C4, and CAM plants all have cells that have chloroplasts which attach CO2 directly to ribulose bisphosphate to produce sugars.
2. CAM plants have one set of cells that harvests CO2 and passes the carbon to another set of cells that builds sugars.
3. Stomata open at night to allow gas exchange and sugars are produced during the day.
The statement that applies to all three types of photosynthesis is: Light energy, CO2, and H20 are needed to make sugars.
C4 and CAM plants have adaptations that prevent the Calvin cycle from shutting down in periods of dryness. These adaptations include C4 plants using a carbon concentrating mechanism that separates the fixation of CO2 from the Calvin cycle and CAM plants using a process called crassulacean acid metabolism (CAM), where CO2 is taken up at night and stored as an acid until the following morning when it is converted into sugars in the Calvin cycle.

Newsvendor: National Geographic still sells a considerable number of copies. Its demand for the August issue is forecasted to be normally distributed with a mean of 80 and a standard deviation of 25. If a store stocks 100 copies, how many copies can they expect to return to the publisher at the end of the month
Thus, the store can expect to return about 36 copies to the publisher at the end of the month.
The newsvendor problem is a classic inventory optimization problem that seeks to balance the costs of overstocking and understocking.
In this case, we have the demand for the August issue of National Geographic magazine, which is normally distributed with a mean of 80 and a standard deviation of 25.
The store stocks 100 copies of the magazine and wants to know how many copies it can expect to return to the publisher at the end of the month.
To solve this problem, we need to use the normal distribution formula, which is:
Z = (X - μ) / σ
where Z is the standard score, X is the number of copies sold, μ is the mean, and σ is the standard deviation.
We can use this formula to find the probability of selling all 100 copies, which is:
Z = (100 - 80) / 25 = 0.8
P(Z < 0.8) = 0.7881
This means that there is a 78.81% chance of selling all 100 copies.
To find the expected number of returns, we can subtract the expected number of sales from the initial stock:
Expected returns = 100 - (80 x 0.7881) = 36.36
Therefore, the store can expect to return about 36 copies to the publisher at the end of the month.

which measure of center can you most accurately estimate from this information: Median
The median divides the data into equal-sized groups. So approximately 50% of the data is above the median and approximately 50% of the data is below the median.
Calculating the median
The median is the value in a data set, implying that half of data focuses have a value more modest or equivalent to the median and half of data focuses have a value higher or equivalent to the median.
For a little data set, you first count the quantity of data focuses (n) and organize the data focuses in expanding request. Assuming the quantity of data focuses is lopsided, you add 1 to the quantity of places and separation the outcomes by 2 to get the rank of the data point whose value is the median.

The key of a basketball court is made up of a rectangle and on semicircle. the length of the rectangle is 15 feet and the width is 10 feet. find the area of the key
The area of the rectangle is 150 square feet, and the area of the semicircle is approximately 39.27 square feet. Thus, the total area of the key on the basketball court is approximately 189.27 square feet.
To calculate the area of the key on a basketball court, we need to find the area of the rectangle and the area of the semicircle separately and then sum them up.
Area of the Rectangle:
The length of the rectangle is 15 feet and the width is 10 feet.
Area of the rectangle = Length * Width = 15 feet * 10 feet = 150 square feet.
Area of the Semicircle:
The radius of the semicircle is half the width of the rectangle, which is 10 feet / 2 = 5 feet.
The formula for the area of a circle is A = π * \(r^2\), where π is approximately 3.14159 and r is the radius.
Area of the semicircle = (π *\((5 feet)^2\)) / 2 = (3.14159 * 25 square feet) / 2 ≈ 39.27 square feet.
Total Area of the Key:
To find the total area of the key, we add the area of the rectangle and the area of the semicircle:
Total area of the key = Area of the rectangle + Area of the semicircle
Total area of the key = 150 square feet + 39.27 square feet ≈ 189.27 square feet.
Therefore, the area of the key on the basketball court is approximately 189.27 square feet.

The area of the key on the basketball court is approximately 189.25 square feet.
To find the area of the key on a basketball court, we need to calculate the combined area of the rectangle and semicircle.
The rectangle's area is calculated by multiplying its length by its width:
Rectangle Area = Length × Width = 15 feet × 10 feet = 150 square feet
The semicircle's area is half the area of a full circle with a radius equal to the width of the key. Since the width of the key is 10 feet, the radius is 5 feet.
Semicircle Area = (1/2) × π × \(Radius^2\) = (1/2) × 3.14 ×\((5 feet)^2\) ≈ 39.25 square feet
Therefore, the area of the key is the sum of the rectangle's area and the semicircle's area:
Key Area = Rectangle Area + Semicircle Area = 150 square feet + 39.25 square feet ≈ 189.25 square feet
So, the area of the key on the basketball court is approximately 189.25 square feet.
