A point is equidistant from the two sides of an angle, then it is option (C) on the angle bisector is the correct answer.
What is angle bisector theorem?An angle bisector is a straight line drawn from the vertex of a triangle to its opposite side in such a way, that it divides the angle into two equal or congruent angles.
For the given situation,
Any point that is on the angle bisector is an equal distance ("equidistant") from the two sides of the angle.
A point which is always equidistant from all the sides is the point of intersection of internal angle bisectors.
Hence we can conclude that a point is equidistant from the two sides of an angle, then it is option (C) on the angle bisector is the correct answer.

Billy has 1 gallon of paint. He is going to pour it into a paint tray that measures 10 inches wide, 14 inches long, and 4 cm deep.
(1 gallon = 231 in3, 1 inch = 2.54 cm)
hich of the following scenarios will happen?
The paint will not fill the tray by 441 cm3.
The paint will not fill the tray by 10.53 in3.
The paint will fill the tray exactly.
The paint will overfill the tray by 10.53 in3.
find volume of tray:
convert 4cm to inches 4/2.54 = 1.575 inches
volume = 10*14*1.575 = 220.47 cubic inches
1 gallon = 231 cubic inches
231-220.47 = 10.53 more paint in a gallon
so the paint will over fill the tray by 10.53 in3
Answer:
The answer is:
The paint will overfill the tray by 10.53 in3 (cubic inches).
Step-by-step explanation:
In order to determine the correct option, first we have to get the volume of the tray.
The volume of the tray is a solid prism, where its formula is:
width=10 in
length=14 in
deep=4 cm=[tex]\frac{4}{2.54} =1.575[/tex] in
Volume=[tex]10*14*1.57=220.5[/tex] cubic inches
The value of the deep measure was changed from cm to inches units.
We subtract the allowed volume of the gallon with the volume tray:
231-220.5=10.5 cubic inches
It means that 1 gallon of paint is enough to paint the tray, where the remaining paint is 10.5 cubic inches.
Finally, the correct option is:
The paint will overfill the tray by 10.53 in3 (cubic inches).

what is the inverse of the function f(x) = 2x + 1
the inverse of the function [tex]\( f(x) = 2x + 1 \)[/tex] is [tex]\( f^{-1}(x) = \frac{x - 1}{2} \).[/tex]
To find the inverse of the function [tex]\( f(x) = 2x + 1 \)[/tex], we'll switch the roles of [tex]\( x \)[/tex] and [tex]\( y \)[/tex] and solve for [tex]\( y \)[/tex].
1. Start with the original function:
[tex]\[ f(x) = 2x + 1 \][/tex]
2. Swap [tex]\( x \)[/tex] and [tex]\( y \)[/tex]:
[tex]\[ x = 2y + 1 \][/tex]
3. Solve for [tex]\( y \)[/tex]:
[tex]\[ x - 1 = 2y \][/tex]
[tex]\[ \frac{x - 1}{2} = y \][/tex]
So, the inverse function [tex]\( f^{-1}(x) \)[/tex] is:
[tex]\[ f^{-1}(x) = \frac{x - 1}{2} \][/tex]
Therefore, the inverse of the function [tex]\( f(x) = 2x + 1 \)[/tex] is [tex]\( f^{-1}(x) = \frac{x - 1}{2} \).[/tex]

Find the circumference of a circle whose area is 24pi ft^2
Answer:
30.76 [tex]ft^{2}[/tex]
Step-by-step explanation:
To calculate the circumference of a circle you just have to multiply the diameter by pi.
C= D*[tex]\pi[/tex]
And in order to calculate the value of the diameter you have to clear the formula for the area.
A= [tex]r^{2} *\pi[/tex]
r=[tex]\sqrt{\frac{24 \pi }{\pi } }[/tex]
r=[tex]\sqrt{24}[/tex]
r=4,89
Once we get the radius, we only have to calculate the diameter:
D=2r=9,79
now we just calculate the circumference:
C=D*[tex]\pi[/tex]= (9.79)(3.14)= 30.76

A dogs weight increased by 50% in 3 years . By the end of the 3years , the dog weighed 45 pounds . How much did the dog weigh 3 years ago
Final answer:
To calculate the dog's weight from three years ago, we take the current weight and divide it by 1.50 since the weight increased by 50%. The equation 1.50 * x = 45 pounds results in x = 30 pounds, indicating the dog weighed 30 pounds three years ago.
Explanation:
The question concerns the original weight of a dog whose weight increased by 50% over a period of three years, bringing its weight to 45 pounds at the end of that period. To determine the dog's weight from three years ago, we use the following steps:
Understand that a 50% increase implies that the final weight is 150% of the original weight (100% + 50%).
Represent the original weight as 'x'.
Set up the equation: 1.50 * x = 45 pounds.
Divide both sides by 1.50 to solve for 'x': x = 45 / 1.50.
Calculate 'x' to find that 'x' equals 30 pounds.
Therefore, the dog weighed 30 pounds three years ago.

Create a set of data that contains 11 test scores and satisfies each condition below:
Mean: 83
Median: 81
Mode: 80
Range: 26
Answer:
An example of a data set that satisfies each of these conditions is:
[72, 75, 79, 80, 80, 81, 82, 84, 88, 94, 98]
Step-by-step explanation:
Let's start by defining the terms:
Mean: Average of all numbers
Median: Middle score in a set of given numbers
Mode: Most frequently occuring number
Range: Difference between the lowest and highest number
There are many possible data sets for these conditions, but these are the numbers I found work. I'm sure there is a simpler way to figure this out, but this way makes the most sense to me. This was my process.
We know that all of our numbers need to add up to 913. We know this because our mean is 83 and there are 11 numbers (83X11=913). We can check this by taking 913/11 (the number of scores)=83 (mean)
We know that the median needs to be 81. When the numbers are in order lowest to highest, we would need to have 5 numbers below 81 and 5 numbers above 81. The sixth number in the set should be 81.
We know the mode is 80, so 80 has to be in our data set at least twice with all other numbers appearing less often. This is why I put two 80s and one of every other number in my data set.
I then picked the lowest number in my data set, ensuring that a range of 26 would allow me enough space on both sides of the median. Since I have my lowest number, I can add 26 and get the highest number in my data set.
Once I have the main numbers, I just need to put other numbers before and after the median that would give me a sum of 913 (see the section about the mean). These can be any numbers that go in the right order as long as they don't change any of the numbers we've already established and they total 913.

Which best describes the range of the function f(x) = 2(1/4) after it has been reflected over the y-axis? all real numbers all real numbers less than 0 all real numbers greater than 0 all real numbers less than or equal to 0
Answer:
All real numbers greater than 0.
Step-by-step explanation:
We have the function, [tex]f(x) = 2(\frac{1}{4})^{x}[/tex].
'Reflection over y-axis means to flip the graph over y-axis', which changes the function by f(x) becomes f(-x).
So, after reflection, the given function transforms into,
[tex]g(x)=f(-x)[/tex]
i.e. [tex]g(x)=2(\frac{1}{4})^{-x}[/tex]
According to the graph of the function g(x), we see that,
Range of [tex]g(x)=2(\frac{1}{4})^{-x}[/tex] is the 'Set of all real non-negative numbers' i.e. {x | x > 0} i.e. [tex](0,\infty)[/tex]

The graph of f(x) = (0.5)x is replaced by the graph of g(x) = (0.5)x − k. If g(x) is obtained by shifting f(x) down by 2 units, the value of k is ________. Numerical Answers Expected!
Answer: The value of k is 2.
Step-by-step explanation:
Given : The graph of [tex]f(x)=(0.5)x[/tex] is replaced by the graph of [tex]g(x)=0.5)x-k.[/tex]
If g(x) is obtained by shifting f(x) down by 2 units, then [tex]g(x)=(0.5)-2[/tex]
[since f(x)shifted down down by 2 , so only the value of dependent variable effect]
When we compare both functions of g(x), we found that k=2.
Hence, the value of k is 2.
The value of [tex]k[/tex] is 2.
The following information should be considered:
when [tex]g(x)[/tex] is obtained by shifting f(x) fall by 2 units so [tex]g(x) = (0.5) - 2.[/tex]Since [tex]f(x)[/tex] shifted down by 2 so there is the effect on the dependent variable. Now at the time of comparing both functions of g(x) the k should be 2.Learn more: brainly.com/question/17429689

simplify square root of 1.69
In the given problem, the square root of 1.69 is 1.3.
The square root of a non-negative real number is a value that, when multiplied by itself, results in the original number. In mathematical notation, the square root of the number "x" is represented by the symbol "√x."
The square root is an inverse operation of squaring, which means that if one squares a number and then take its square root, he or she gets back to the original value. The concept of the square root is nearly related to obtaining the side length of a square with a given area or obtaining the magnitude of a vector in mathematics.
1.69 also can be written as [tex]\dfrac{169}{100}[/tex] in fraction form.
[tex]\sqrt{\dfrac{169}{100}} = \sqrt{\dfrac{13^2}{10^2} }[/tex]
[tex]= \sqrt{(\dfrac{13}{10} )^2}\\= \dfrac{13}{10} \\= 1.3[/tex]
Thus, 1.3 is the square root of 1.69.
