The measure of ∠AKG is 133°.
What is m∠AKD?
Enter your answer in the box.
m∠AKD =
Answers
133° = mes ∠ AKD + 87°
133° - 87° = mes ∠AKD
∠AKD = 46°
To find m∠AKD, subtract the measure of ∠AKG from 180 degrees.
Explanation:To find the measure of ∠AKD, we need to use the fact that the sum of the measures of angles in a triangle is 180 degrees. Since we know that ∠AKG is 133 degrees, we can subtract this from 180 to find the remaining angle.
180 - 133 = 47 degrees
Therefore, m∠AKD = 47 degrees.

Roni and Allie are mowing the grass at the soccer field. Roni has a riding lawn mower and can mow the field in 30 minutes. Allie is pushing a lawn mower and can mow the field in 75 minutes.
If Roni and Allie work together to mow the field, what part of the field would Roni mow?
A. about 0.52 of the field
B. about 0.64 of the field
C. about 0.71 of the field
D. about 0.87 of the field
Answers
Answer: C. about 0.71 of the field
Step-by-step explanation:
Since, Roni can mow the field in 30 minutes.
Thus, the work done by Roni in one day = 1/30
And, Allie can mow the field in 75 minutes.
Thus, the work done by Allie in one day = 1/75
⇒ The total work done by Roni and Allie in one day when they worked simultaneously,
= [tex]\frac{1}{30} + \frac{1}{75}[/tex]
= [tex]\frac{5}{150} + \frac{2}{150}[/tex]
= [tex]\frac{7}{150}[/tex]
[tex]\implies \text{The part of work done by Roni} = \frac{\text{the work done by her in one day}}{\text{Total work they done in one day}}[/tex]
[tex]= \frac{1/30}{7/150}[/tex]
[tex]= \frac{5}{7}=0.714285714\approx 0.71[/tex]
⇒ Option C is correct.

The equation of a parabola is given.y=1/8x^2+4x+20 What are the coordinates of the focus of the parabola?
Answers
You may write the equation as
(y-1)^2 = (1) (x+4)
(y-k)^2 = 4p(x-h), where (h,k) is the vertex
4p=1
p=1/4
k=1
h=-4
The directrix is a vertical line x= h-p
x = -4-1/4
x=-17/4
-------------------------------
What is the focal length of the parabola with equation y - 4 = 1/8x^2
(x-0)^2 = 8(y-4)
The vertex is (0,4)
4p=8
p=2 (focal length) -- distance between vertex and the focus
-------------------------------
(y-0)^2 = (4/3) (x-7)
vertex = (7,0)
4p=4/3
p=1/3
focus : (h+p,k)
(7+1/3, 0)
y = 1/8(x + 16)^2 - 12
so the vertex is at (-16,-12) and the x coordinate of the focus will be -16)
The focus will be at (-16, k + p) Here k = -12 from the vertex equation and p = 1 / 4a where a = 1/8 so p = 1 / 1/2 = 2 So k + p = -12 + 2 = -10
So the coordinates of the focus are (-16, -10) answer

Because the triangle is a right angle (indicated by the figure), we can determine the lengths of BC and AC easily.
The length of BC is the change in the x-coordinates, and AC is the change in the y-coordinates.
BC = 2 - (-2) = 4
AC = 4 - 1 = 3
To find AB, use the distance formula (the same as the Pythagorean theorem).
AB = √[(2-(2)) ²+ (4-1)² ] = √(4²+3²) = √25 = 5
The area of the triangle is (1/2)*BC*AC = (1/2)*4*3 = 6

A total of 231 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was two times the number of adult tickets sold. How many adult tickets were sold?
Answers
Final answer:
To determine the number of adult tickets sold for the school play, an equation was set up using algebra with x representing adult tickets, which turned out to be 77 after solving the equation x + 2x = 231.
Explanation:
The student has asked to find out how many adult tickets were sold when a total of 231 tickets were sold for a school play, with the number of student tickets being two times the number of adult tickets. To solve this, we can use algebraic methods and set up an equation.
Let x be the number of adult tickets sold, then the number of student tickets sold would be 2x. Given that the total number of tickets is 231, we can write the equation as:
x + 2x = 231
Simplifying, we get:
3x = 231
Dividing both sides by 3, we find that:
x = 77
Therefore, 77 adult tickets were sold.

Use the premises and conclusion to answer the questions.
Premises:
If a quadrilateral has two pairs of parallel sides, then it is a parallelogram.
If a quadrilateral is a parallelogram, then its opposite angles are congruent.
Conclusion:
If a quadrilateral has two pairs of parallel sides, then its opposite angles are congruent.
Which statement best describes this argument?
The argument is valid by the law of syllogism.
The argument is invalid because the conclusion does not follow the premises.
The argument is valid by the law of detachment.
The argument is invalid because the premises are not true.
Answers
Answer:
The argument is valid by the law of syllogism.
Step-by-step explanation:
The law of syllogism is also called the law of transitivity. It is based on the transitive property, which states "if a = b and b = c, then a = c."
In our problem, our statement a would be "A quadrilateral has two pairs of parallel sides". Our statement b would be "It is a parallelogram." Our statement c would be "Its opposite angles are congruent."
That would make "if a = b"
"If a quadrilateral has two pairs of parallel sides it is a parallelogram."
Then "b = c" would be
"If a quadrilateral is a parallelogram, its opposite angles are congruent."
"a = c" would then be
"If a quadrilateral has two pairs of parallel sides its opposite angles are congruent."
This is the conclusion we were given, so this is the law of syllogism.

The iq scores of the five members of the duluth family are 100, 82, 104, 96, and 118. for this distribution of scores, the range is:
Answers
The range is the difference between the biggest and smallest number.
Let R = range
R = 118 - 82
R = 36
The range is 36.
Final answer:
The range of the IQ scores (100, 82, 104, 96, and 118) for the Duluth family is calculated by subtracting the lowest score from the highest (118 - 82), resulting in a range of 36 points.
Explanation:
The IQ scores of the five members of the Duluth family are 100, 82, 104, 96, and 118. To find the range of this distribution of scores, you first identify the highest and lowest scores in the set. The highest IQ score is 118, and the lowest is 82. The range is the difference between the highest and lowest scores, so:
Range = Highest score - Lowest score
Range = 118 - 82
Range = 36
Therefore, the range of the distribution of IQ scores for the Duluth family is 36 points.
