Answer:
A.Acute angle
Step-by-step explanation:
We are given that an obtuse angle
We have to find that which type of angle of bisector of an obtuse angle.
Bisector of an obtuse angle means it is divided into two equal parts.
Obtuse angle is that angle whose measurement is greater than 90 degrees and less than 180 degrees.
Suppose, we have an obtuse angle =100 degrees
After bisection , it divides into two equal parts
Let x and x are two equal parts of given obtuse angle
[tex]x+x=100[/tex]
[tex]2x=100[/tex]
[tex]x=\frac{100}{2}=50[/tex]
Each angle measurement=50 degrees < 90 degrees
The angle which is less than 90 degrees and greater than zero degrees is called acute angle.
Hence, the bisector of an obtuse angle forms acute angles.

kelly subscribes to a service called mysongs for downloading music she pays a $7 fee each month to download an unlimited numbers of songs at $0.20 each last month kelly's bill was $23.80
subtract the fee from the total to get the amount actually spent on songs
23.80-7 = 16.80
divide that amount by price per song to get number of songs downloaded
16.80 /0.20 = 84 songs
Zeke ran 4 miles in 45 minutes. if he keeps up the same pace, how long will it take him to run 10 miles?
Final answer:
Zeke's pace is approximately 5.33 miles per hour. To run 10 miles at this pace, it will take him about 113 minutes.
Explanation:
To solve how long it will take Zeke to run 10 miles at the same pace, we need to establish his running speed. We know that Zeke ran 4 miles in 45 minutes, which we can convert to hours for simplicity. Since there are 60 minutes in an hour, this is ⅔ of an hour. So, Zeke's pace is 4 miles per ⅔ hour, or 4 miles per 0.75 hours, which is ≈ 5.33 miles per hour.
Now, we use this pace to determine how long it will take him to run 10 miles. If Zeke runs at a pace of 5.33 miles per hour, then we can calculate the time for 10 miles by dividing the distance by the speed:
Time = Distance ÷ Speed
Time = 10 miles ÷ 5.33 miles/hour
Time ≈ 1.88 hours
Since we want the time in minutes, we multiply by 60 minutes per hour:
1.88 hours × 60 minutes/hour ≈ 112.8 minutes
So, it would take Zeke approximately 113 minutes to run 10 miles at the same pace.

Given the two original statements, can a true conclusion be met? If so, what would it be? If not, why not?
1) If it is June, then it is summer.
2) It is summer.
Conclusion:
From the two original statements above, the answer would be yes, a true conclusion can be met since then It is summer.
What is a possibility?Multiply the total number of possible outcomes by the total number of events. Divide the total number of ways the event can occur by the total number of possible outcomes after determining the probability event and its corresponding consequences.
Given:
1) If it is June, then it is summer.
2) It is summer.
Based on the two original statements, a true conclusion can be made.
Statement 1) says that if it is June, then it is summer. Statement 2) says that it is summer.
Therefore, we can conclude that it is possible that it is June.
However, we cannot conclude for certain that it is June, because there could be other times of the year when it is also summer (depending on the geographic location). For example, in the southern hemisphere, December is summer, not June.
So a possible true conclusion based on these statements is "It is possible that it is June."

Which of the following equations represents a line that is perpendicular to the line that passes through the points below?
(-8, -10) (-6, -2)
Thank you!
By calculating the slope of the line passing through the given points to be 4, the slope of any line perpendicular to this would have the opposite reciprocal, -1/4. Without a specified point for the line to pass through, (0,0) is used and the equation of the perpendicular line is y = -1/4x.
Explanation:The first step to finding a line perpendicular to another is understanding the concept behind the slope of a line. The slope of a line is determined by comparing the vertical change (rise) to the horizontal change (run) between two points on a line.
For the points (-8, -10) and (-6, -2), the slope would be calculated as follows: (change in y)/(change in x), which in this case would be (-2 - (-10))/(-6 - (-8)). Simplifying that expression gives us a slope of 4.
The opposite reciprocal of 4 is -1/4 (we flipped the fraction and changed the sign). This is the slope of all lines perpendicular to the original line.
Lastly, for the equation of a line, we need a point for the line to pass through, since the question didn't specify a point, we can use (0,0), so the equation of our perpendicular line is y = -1/4x.

We are given a triangle JKL.
<J =5x°
<K = 2x°
<L = 3x°.
Note: Sum of angles of a triangle is 180°.
Therefore, <J +<K+<L = 180°.
5x +2x+3x = 180°.
10x = 180
Dividing both sides by 10, we get
10x/10=180/10
x = 18.We need to find the m<L.
m<L =3x° = 3(18) = 54°.
Therefore, m<L = 54°.How do you solve for percent increase and percent decrease?
for increase:
Increase = New Number - Original Number
Then divide the increase by the original number and multiply the answer by 100
For decrease:
Decrease = Original Number - New Number
Then divide the decrease by the original number and multiply the answer by 100

Which equation in point-slope form contains the points (8, 10) and (–4, 2)?
The equation in point-slope form containing the points (8, 10) and (-4, 2) is y - 10 = (2/3)(x - 8).
Explanation:The point-slope form of a linear equation is given by where (x1, y1) represents the given point and m represents the slope. To find the equation in point-slope form containing the points (8, 10) and (-4, 2), we need to calculate the slope first. The slope m can be calculated using the formula m = (y2 - y1) / (x2 - x1).
Using the given points (8, 10) and (-4, 2), we can substitute the values into the formula to find the slope:
Now that we have the slope, we can use one of the given points to write the equation in point-slope form. Let's use the point (8, 10):

What is the area of a parallelogram whose vertices are A(−12, 2) , B(6, 2) , C(−2, −3) , and D(−20, −3) ?
Enter your answer in the box.
To solve this, we simply have to get the length and the width. Based from the graph, we can see that the length is connected by 2 points (-12, 2) and (6, 2) or (-20, -3) and (-2, -3). The height between the two lengths is 5 which can be counted manually.
We use the distance formula to calculate the length from either pair of points.
length^2 = [(-12 – 6)^2 + (2 – 2)^2]
length = 18
Therefore the area is:
Area = length * height
Area = 18 * 5
Area = 90

Which of the following number lines represents the solution set of 11 + x ≥ 14?
Answer:
The line that represents the solution set of [tex]11+x\geq 14[/tex] is the second one.
Step-by-step explanation:
If we want to find the line, we need to solve the inequality.
The inequality is [tex]11+x\geq 14[/tex]
If we solve it in terms of x :
[tex]11+x\geq 14[/tex]
[tex]x\geq 14-11[/tex]
[tex]x\geq 3[/tex]
This means that the solution of the inequality [tex]11+x\geq 14[/tex] are all real numbers greater or equal to 3.
The line that represents [tex]x\geq 3[/tex] is the blue line in the second number line.
It is important to notice that [tex]x>3\neq x\geq 3[/tex] because in the second expression the number 3 is included.
In the second line the number ''3'' is included because there is a blue point in the number 3 instead of the first number line where in the number ''3'' the blue point is empty.
The line parallel to y=9x+4 that passes through (2,7)
The equation of the line parallel to y=9x+4 that passes through (2,7) is y = 9x - 11
The equation of a line in point-slope form is expressed as:
y - y0 = m(x-x0)
m is the slope of the line
(x0, y0) is any point on the line
Given the equation y = 9x + 4, the slope of the line is expressed as:
mx = 9x
m = 9
We will use the same slope since the lines are parallel
Substitute the slope and the given point into the formula;
y - 7 = 9 (x -2)
y - 7 = 9x - 18
y = 9x -18 +7
y = 9x - 11
Hence the equation of the line parallel to y=9x+4 that passes through (2,7) is y = 9x - 11
