Classify the following triangle based on its angle measures.
A) Obtuse
B)Acute
C)right
D)equiangular
Answer:
A) Obtuse
Step-by-step explanation:
It is Obtuse due to the angle 115° being in the Triangle. This rules out Acute since the middle angle is not less than 90°. It is not Equiangular since all three angles are not equal. Furthermore it is not a right triangle either since there is no 90° angles. Making it Obtuse.
To classify a triangle based on angle measures, we need to know the specific angles. Triangles can be obtuse, acute, right, or equiangular, and each type has its own unique properties used in various applications across different fields.
Explanation:To classify the following triangle based on its angle measures, we must first understand the definitions of different types of triangles. A triangle can be classified as:
Obtuse: One angle is greater than 90 degrees.Acute: All angles are less than 90 degrees.Right: One angle is exactly 90 degrees.Equiangular: All angles are equal, and each measure 60 degrees since the sum of the angles in any triangle is 180 degrees.Considering these definitions, the seeking student must provide the angle measures of their specific triangle to accurately classify it.
Why Make These Distinctions?Making distinctions between different types of triangles is crucial because each classification has unique properties that are important in various fields such as mathematics, engineering, architecture, and physics. These properties assist in solving problems and understanding the world around us.
For instance, an obtuse triangle may be used in special construction scenarios, while right triangles are essential in trigonometry and geometry, appearing frequently in real-life applications like building and navigation.

The graphs below are both quadratic functions. The equation of the red graph is
x)= x. Which of these is the equation of the blue graph, g(x)?
Answer:
D. [tex]g(x)=\frac{1}{5}x^2[/tex]
Step-by-step explanation:
The equation of the red quadratic graph is [tex]f(x)=x^2[/tex].This is the parent quadratic function or the base of the quadratic functions.This red quadratic graph has been dilated by a certain scale factor to obtain the blue graph. Recall that, when the scale factor is a fraction, such that [tex]0\:<\:k\:<\:1[/tex] the graph is stretched horizontally.The dilated graph then becomes wider than the parent function.From the given function equations, the possible value of k can only be [tex]k=\frac{1}{5}[/tex].Therefore the blue graph has equation: [tex]g(x)=\frac{1}{5}x^2[/tex]The correct answer is D.What is the solution for in (3x-5)=in11+2?
a. x=8
b. x=9
c. x=-3
d. x=7
Answer:
x = 3.133
Step-by-step explanation:
I'm going to take a chance and assume that you meant "ln 11," not "in11."
If I'm right, then we have:
3x-5 = ln 11 + 2.
Adding 5 to both sides yields
3x = ln 11 + 2 + 5, or ln 11 + 7. Since ln 11 = 2.398,
3x = 2.398 + 7, or 3x = 9.398, and so
x = 3.133.

the number of lattes sold daily for two coffee shops is shown in the table: Lattes 12 52 57 33 51 15 46 45 Based on the data, what is the difference between the median of the data, including the possible outlier(s) and excluding the possible outlier(s)?
A. 48.5
B. 23
C. 8.4
D. 3
Answer:
Option 4 (3)
Step-by-step explanation:
The first step involved in calculating the median it to list the observations in the ascending order. This gives:
12 15 33 45 46 51 52 57.
The second step is to identify the middle number (in case the observations are in odd numbers) or numbers (in case the observations are in even numbers) after the ascending order step has been done. It can be observed that the middle numbers in this data set are 45 and 46. Since there are two numbers, so their average will be the median of this data set. Therefore, the median is 45.5.
It can be observed that that there are 2 outliers in the data set: 12 and 15. Once removed, the data set will be:
33 45 46 51 52 57.
The middle numbers are 46 and 51 and the mean of the two middle numbers is 48.5.
Therefore, the difference between the median of the data, including the possible outliers and excluding the possible outliers is given by 48.5 - 45.5 = 3. Therefore, Option 4 is the correct answer!!!

Answer:
4xy[2xy - x - 3]
Step-by-step explanation:
When finding the Greatest Common Factor [GCF], along with the coefficient, you have to factor out the least degree term possible, which in this case is 4xy. This is because although all terms have y and x, their degrees are not all similar, so we have to go with 4xy.
Let f(x) = 8x and g(x) = x - 3. What's
the smallest number that is in the domain of
fog?
Answer:
The smallest number that is in the domain of fog is 3
Step-by-step explanation:
f(x) = [tex]\sqrt{8x}[/tex] (as corrected in comments)
g(x) = x-3
we need to find fog = f(g(x))
For finding f(g(x)) we put the value of g(x) inside the f(x)
f(g(x))=[tex]\sqrt{8(x-3)}[/tex]
The domain of this function is x ≥ 3
because if value of x is less than 3 than the result would be negative and we know √f(x) ≥ 0
So, the smallest number that is in the domain of fog is 3
Say your car doesn’t run on straight gasoline and you have to mix the oil with gas together in a specific ratio of 2.4 fl oz of oil for every gallon of gasoline. If you have 1.5 gallons of gas, how much oil should you add?
Answer:
3.6 fl oz
Step- by-step explanation:
Well if one gallon equal 2.4 fl oz that would mean that half of a gallon would be half of that amount. Half of that amount would be 1.2 fl oz. we have now found how much a full gallon needs and how much half a gallon need. Now we add these 2 numbers. 2.4 fl oz + 1.2 fl oz = 3.6 fl oz.
Please give me Brainliest.
Final answer:
To get the correct oil mix for 1.5 gallons of gasoline at a ratio of 2.4 fl oz of oil per gallon, you should add 3.6 fl oz of oil.
Explanation:
To calculate the amount of oil needed for 1.5 gallons of gasoline with a mix ratio of 2.4 fl oz of oil per gallon, you follow these steps:
Determine the amount of oil needed for one gallon of gas, which is 2.4 fl oz.
Multiply this amount by the total gallons of gas. In this case, 2.4 fl oz x 1.5 gallons.
The calculation will be 2.4 fl oz/gallon x 1.5 gallons = 3.6 fl oz of oil.
Therefore, you should add 3.6 fl oz of oil to 1.5 gallons of gasoline to achieve the correct mix ratio.

0=-12
what does 0 = -12 mean regarding the solution to the system?
Answer: There are no solutions to the system because the equations represent parallel lines.
The value 0 = -12 indicates an inconsistent system with no solution.
0 = -12 means that the system of equations is inconsistent, and there is no solution. In this case, the equations represent parallel lines that never intersect, hence no common solution exists.

Step-by-step explanation:
Givens
a = 12 cm
b = 12 cm
c = ??
The triangle is isosceles with 1 right angle and 2 45 degree angles.
Formula
c^2 = a^2 + b^2
c^2 = 12^2 + 12^2
c^2 = 144 + 144
c^2 = 288
c^2 = 144 * 2
c = sqrt(144) * sqrt(2)
c = 12 * sqrt(2)
The answer isn't there. 12*sqrt(2) is the correct answer, 12sqrt(3).

A rectangular prism has a length of 2 1/4 feet, a width of 6 feet, and a height of 3 1/2 feet.
What is the volume of the prism?
Enter your answer in the box.
ft³
For this case we have by definition, that the area of a rectangular prism is given by:
[tex]V = A_ {b} * h[/tex]
Where:
[tex]A_ {b}:[/tex] is the area of the base
h: It's the height
Before finding[tex]A_ {b}[/tex]we convert the mixed numbers to fractions:
length: [tex]2 \frac {1} {4} = \frac {4 * 2 + 1} {4} = \frac {9} {4}[/tex]
width: 6
Height:[tex]3 \frac {1} {2} = \frac {2 * 3 + 1} {2} = \frac {7} {2}[/tex]
So, we have to:[tex]A_ {b} = \frac {9} {4} * 6 = \frac {54} {4} = 13.5[/tex]
Finally, the volume is given by:
[tex]V = 13.5 * \frac {7} {2} =47.25\ ft ^ 3[/tex]
Answer:
[tex]47.25 \ ft ^ 3[/tex]
ANSWER
[tex]Volume = 47\frac{1}{4} {ft}^{3} [/tex]
EXPLANATION
The formula for calculating the volume of a rectangular prism is
[tex]Volume = l \times b \times h[/tex]
Where
[tex]l = 2 \frac{1}{4} ft[/tex]
is the length of the rectangular box,
[tex]w = 6ft[/tex]
is the width and
[tex]h = 3 \frac{1}{2} ft[/tex]
is the height of the rectangular prism.
We plug in the given dimensions into the formula to get:
[tex]Volume = 2 \frac{1}{4} \times 6 \times 3 \frac{1}{2} [/tex]
Convert the mixed numbers to improper fraction to get:
[tex]Volume = \frac{9}{4} \times 6 \times \frac{7}{2} [/tex]
Multiply out to get
[tex]Volume = \frac{189}{4} {ft}^{3} [/tex]
Or
[tex]Volume = 47\frac{1}{4} {ft}^{3} [/tex]

The test contains 14 three-point questions and 10 five-point questions.
The test contains 20 three-point questions and 8 five-point questions.
Answer:
The test contains 10 three-point questions and 14 five-point questions
Step-by-step explanation:
Given equations are:
[tex]x+y = 24\\and\\3x+5y=100[/tex]
From 2nd equation we can deduce that x represents number of 3-point questions and y represents number of 5-point questions.
Using the substitution method:
From x+y = 24
y= 24-x
Putting this valu of y in 3x+5y=100
[tex]3x+5(24-x) = 100\\3x + 120 - 5x = 100\\-2x+120=100\\-2x = 100-120\\-2x = -20\\\frac{-2x}{-2} = \frac{-20}{-2}\\ x = 10\\Putting\ the\ value\ of\ x\ in\ x+y=24\\10+y=24\\y = 24-10\\y = 14[/tex]
Hence, the correct answer is:
The test contains 10 three-point questions and 14 five-point questions..
Which formula can be used to describe the sequence
-3, 3/5, -3/25, 3/125, -3/625
Answer:
a(n) = -3(-1/5)^(n - 1)
Step-by-step explanation:
From the first term, -3, we get the second term, 3/5, by multiplying -3 by -1/5.
Thus, the common ratio is -1/5.
The general formula in this case is a(n)=(first term)(common ratio)^(n - 1), or
a(n) = -3(-1/5)^(n - 1)

Answer:
[tex]\frac{4x^3-3x^2+5x+6}{x+6}=4x^2-27x+167-\frac{996}{x+6}[/tex]
Step-by-step explanation:
The division problem given to us is [tex](4x^3-3x^2+5x+6)\div (x+6)[/tex].
To perform the synthetic division, we write out the coefficient of the polynomial. We set the linear factor to zero and solve for x, this becomes our divisor. That is [tex]x+6=0\implies x=-6[/tex].
We carry out the synthetic division as shown in the attachment.
The result of the synthetic division is 4 -27 167 -996
The first three terms are the coefficients of the quotient and the last term is the remainder.
Therefore the quotient is [tex]q(x)=4x^2-27x+167[/tex] and the remainder is [tex]r(x)=-996[/tex].
The dividend, the quotient and the divisor are written as
[tex]\frac{4x^3-3x^2+5x+6}{x+6}=4x^2-27x+167-\frac{996}{x+6}[/tex]

ANSWER
[tex]y = 4x - 2[/tex]
EXPLANATION
The equation of a straight line can be found using the formula
[tex]y =mx + b[/tex]
We have that,the y-value increases by 4 for every x that increases by 1.
This implies that, the slope is
[tex]m = \frac{4}{1} = 4[/tex]
The line also crosses the y-axis at –2.
Hence the y-intercept is b=-2.
Therefore the equation is
[tex]y = 4x - 2[/tex]
The correct answer is A

John is putting a fence around his garden that is shaped like a half circle and a rectangle.
How much fencing will John need? Use 22/7 for pie
A)32 ft
B)39 ft
C)46 ft
D)57 ft
Answer: C)46 ft
Step-by-step explanation:
We know that the circumference of a circle can be calculated with this formula:
[tex]C=2\pi r[/tex]
Where "r" is the radius of the circle.
Since John is putting a fence around his garden that is shaped like a half circle and a rectangle, then we can find how much fencing he needs by making this addition:
[tex]Fencing=\frac{2\pi r}{2}+2l+w[/tex]
Where "l" is the lenght of the rectangle and "w" is the width of the rectangle.
Since we know that the radius of the circle is half its diameter, we can find "r". This is:
[tex]r=\frac{7ft}{2}=3.5ft[/tex]
Then, substituting values (and using [tex]\pi=\frac{22}{7}[/tex]), we get:
[tex]Fencing=\frac{2(\frac{22}{7})(3.5ft)}{2}+2(14ft)+7ft=46ft[/tex]

which is the graph of g(x)=[x+3]?
The graph of the equation y = x + 3 is a straight line with a slope of 1 and a y-intercept of 3. This means that for every increase of 1 in x, y increases by 1 and the line crosses the y-axis at y = 3.
Explanation:
The student is asking for the graph of the function g(x)=[x+3]. Please note, the symbol '[' and ']' is usually used to denote the greatest integer function or floor function, but since the context is not very clear, I'll assume that this is a simple linear function y = x + 3.
In such case, the graph of y = x + 3 is a **straight line** with a **slope** of 1 and a y-**intercept** of 3. Remember, the ^ slope is the change in y for every increase of 1 in x, and in this equation, for every increase of 1 in x, y increases by 1 . The intercept is simply where the line crosses the y-axis, and in this case it's at y = 3.

Which graph represents the linear function below? y-4= (4/3)(x-2)
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
[tex]y-4=(4/3)(x-2)[/tex]
This is the equation of a line into point slope form
The point is (2.4)
The slope is m=4/3
To plot the line find the intercepts
The y-intercept is the value of y when the value of x is equal to zero
For x=0
y-4=(4/3)(0-2)
y=(-8/3)+4
y=4/3
The x-intercept is the value of x when the value of y is equal to zero
0-4=(4/3)(x-2)
-4=(4/3)x-(8/3)
Multiply by 3 both sides
