The measure of the two angles will be x > 25° and y = 180° - x°.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
The two lines are parallel and the third line is a transversal line.
If one angle is greater than 25°. Then the other angle is given as,
Let the angles be 'x' and 'y'. Then angles are supplementary angles. Then the inequality is given as,
x > 25° ...1
x + y = 180°
y = 180° - x ...2
From equations 1 and 2, then we have
y = 180° - x
The measure of the two angles will be x > 25° and y = 180° - x°.

What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
We know the sum of linear pair of angles is equal to 180°,
(4x + 9)° +(3y)° = 180°.
We also know that pair of alternate interior angles are equal,
3y° = 75°.
y = 25°.

do teenagers prefer yellow candy or pink candy? two different supplements, which have no effect on taste, are used on identical candies to produce a yellow or pink candy. volunteer teenagers are randomly assigned to either pink candy or yellow candy. the participants are then asked to rate the candy on a 1- to 10-point scale. is blinding demonstrated in this experiment? no, because the volunteers do not know the color candy they are getting no, because the volunteers know whether they are eating yellow candy or pink candy yes, by having the experimenter in a separate room pick one of the two containers at random and having a candy pulled from that container remotely yes, by having the statistician analyzing the results not know which volunteer sampled which candy yes, by having the volunteers wear a blindfold while they eat the candy out of the container so they don't know the color of the candy they are tasting
No, blinding was not demonstrated in the experiment because the volunteers knew whether they are drinking purple juice or yellow juice.
What is blinding in an experiment?Blinding is the process of hiding a participant's group assignment from one or more other participants in a clinical research study, most frequently a randomized controlled trial (RCT).
Although the candy has the same flavour as the drink, participants can tell the difference based on colour. No, because the participants are aware of whether they are consuming yellow or purple juice.
To create a yellow or pink candy, two separate additives that don't affect flavour are added to identical sweets.
In each experiment, group allocations are concealed from data analyzers by blinding or masking. This experiment is not a blinding demonstration since the subject is aware of the juice.
As a result, adolescent volunteers are at random allocated either pink candy or yellow candy, both of whom are aware of the juice.

2-5x=2x-2+3x is this equation a 1 solution a no solution or in infinite solution
The linear equation has only one solution, and it is x = 2/5.
How many solutions does the linear equation has?Here we want to see how many solutions does the linear equation have.
The equation is:
2 - 5x = 2x - 2 + 3x
To check that, let's try to solve the equation.
We can simplify the right side to get:
2 - 5x = (2x + 3x) - 2
2 - 5x = 5x - 2
Nowwe canadd 5x in both sides to get:
2 - 5x + 5x = 5x -2 + 5x
2 = 10x - 2
Now add 2 in both sides:
2 + 2= 10x - 2 + 2

A z-score of -2 means that the income of $40,000 is 2 standard deviations below the mean income of $64,000.
The z-score is a standard measure of how many standard deviations a data point is away from the mean. To determine the z-score, we need to use the formula:
z = (x - μ) / σ
Where x is the data point of interest ($40,000), μ is the mean ($64,000), and σ is the standard deviation ($12,000).
Substituting the values:
z = (40000 - 64000) / 12000
z = -2
Therefore, the z-score for someone with an income of $40,000 is -2.
In conclusion, a z-score of -2 means that the income of $40,000 is 2 standard deviations below the mean income of $64,000.

the base of a solid is the region bounded by the ellipse $$. find the volume of the solid given that cross sections perpendicular to the $$-axis are:
The volume of the solid is 16.75 unit³ in the given line x+2y=8 intercseting the x-axis, the y-axis.
What is volumes of Solids?
We shall encounter several solids and their corresponding volumes when discussing the concept of the volume of combination of solids. As is common knowledge, the surface areas and volumes of all three-dimensional shapes depend on their dimensions. As we can see in reality, numerous shapes are created by fusing a variety of shapes. For instance, the combination of a cone and cylinder shapes creates a tent. Similar to how a cone and a hemisphere combine to form an ice cream cone. As a result, the volume of the solids combined will equal the total of the volumes of the individual solids.
The line x+2y=8.
y = (8-x)/2
Volume will be V = π/2 ∫(r²) dr
So we have 1/3 π * r² * h
Here h = 8, r=2.
So V = 1/3 π * r² * h = 1/3 π * 2² * 8
V = 16.75 unit³
Hence ,the volume of the solid is 16.75 unit³

a small apartment has a 11ft by 11ft bedroom, a 4ft by 6ft bathroom, and a single multi-use 15ft by 16ft living room/kitchen. what is the total square footage (area) of the apartment?
The total square footage (area) of the apartment is 385 square feet.
The total square footage, also known as the area, of an apartment is a measure of how much space the apartment has.
First, let's find the area of the 11ft by 11ft bedroom. To do this, we multiply the length and the width of the room. In mathematical terms, the area of a rectangle is equal to the length times the width. So, for the bedroom, the area is
=> 11ft * 11ft = 121 square feet.
Next, let's find the area of the 4ft by 6ft bathroom. The formula for the area of a rectangle is still the same, so the area of the bathroom is
=> 4ft * 6ft = 24 square feet.
Finally, we'll find the area of the multi-use living room/kitchen, which is 15ft by 16ft. The area of this room is
=> 15ft * 16ft = 240 square feet.
Now that we have the area of each room, we can add them together to find the total area of the apartment. So, the total area is
=> 121 square feet + 24 square feet + 240 square feet = 385 square feet.

The population will be 40 thousnd after 22.5 years,and 60 thousand after 34.4 years.
How to estimate the number of years?First, we want to estimate the number of years that takes to reach 40 thousand, to estimate that we need to look at the graph.
We can see that when y = 40, the value of x is between 20 and 25 (almost in the middle)
So here we estimate that the answer is 22.5
b) Now we want to estimate it using the equation
p(x) = 18*e^(0.035*x)
We want to find how many years it takes to reach a population of 60 thousand, then we need to solve:
p(x) = 18*e^(0.035*x) = 60
e^(0.035*x) = 60/18
Using the natural logarithm in both sides:
ln( e^(0.035*x)) = ln(60/18)
0.035*x = ln(60/18)
x = ln(60/18)/0.035 = 34.4

Step-by-step explanation:
Given equation,
→ y = 4x - 2
Now we have to use,
→ y = 18
Then the value of x will be,
→ y = 4x - 2
→ 18 = 4x - 2
→ 18 + 2 = 4x
→ 20 = 4x
→ 4x = 20
→ x = 20 ÷ 4
→ [ x = 5 ]
Hence, the value of x is 5.
