The angle marked x in the regular hexagon is 120 degrees, and in the regular pentagon is 108 degrees.
The angle marked x in the regular hexagon is 120 degrees, because the sum of all the angles in a hexagon is 720 degrees (360 x 2). Each of the angles in a regular hexagon is 120 degrees, so the angle marked x must also be 120 degrees. The angle marked x in the regular pentagon is 108 degrees, because the sum of all the angles in a pentagon is 540 degrees (360 x 1.5). Each of the angles in a regular pentagon is 108 degrees, so the angle marked x must also be 108 degrees.
Regular Hexagon:
Sum of angles = 720 degrees
Number of angles = 6
Angle x = 720 ÷ 6 = 120 degrees
Regular Pentagon:
Sum of angles = 540 degrees
Number of angles = 5
Angle x = 540 ÷ 5 = 108 degrees

The sum of 9 consecutive positive integers is 99. What is the largest of these Intigers?
Answer: 15
Step-by-step explanation:
Let x be the first of the consecutive integers.
So, the consecutive integer after x would be x+1. The one after this one would be x+2. Continue this until there are nine consecutive integers.
x + (x+1) + (x+2) + (x+3) + (x+4) + (x+5) + (x+6) + (x+7) + (x+8) = 99
Simplify:
9x + 36 = 99
9x = 63
x = 7
The largest of these consecutive integers is the last one, x+8. Plug in x to this expression:
(7) + 8 = 15
The largest of these consecutive integers is 15.

In the triangle that contains x (call the other 2 angles as a and b, where a is the angle that is supplemetary to the center angle.)
a = 180 - 110 = 70 (supplemetary angles add up to 180)
b = 30 (b and the angle measures 30 are in the same segment.)
-> x = 180 - 70 - 30 = 80.
2. In triangle PRT, v = 180 - 40 - 70 = 70.
Since P,Q,S,T all lies on the circumference, PQST is a cyclic quadrilateral.
-> w = 180 - PQS = 180 - (180 - 70) = 70.

i) A 1:2 scale means that all sides of P must be shortened by twice the lengths.
Since D is the only shape with the sides shortened from P, it's the correct option.
ii) A 1:1/2 scale means that all sides of P must be enlarged by twice the lengths.
Therefore, the measures of the sides become sqrt(20),6,4,6 (clockwise from diagonal), which is B.

Either draw a full m-ary tree with 76 leaves and height 3, where m is a positive integer, or show that no such tree exists.
If and only if m is a divisor of 76, then there exists a full m-ary tree with 76 leaves and height 3. 1, 2, 4, 19, 38, and 76 are the divisors of the number 76.
One node at the root, 76 child nodes at the second level, and [tex]76^{2}[/tex] = 5776 child nodes at the third level make up the 5776 + 76 = 5852 nodes of a full 1-ary tree with 76 leaves and height 3. As a result, there is no whole 1-ary tree with 76 leaves and a height of 3.
There would be one node at the root, 38 child nodes at the second level, and [tex]38^{2}[/tex] = 1444 child nodes at the third level, making a total of 1444 + 38 = 1482 nodes in a full 2-ary tree with 76 leaves and height 3. As a result, there is a full 2-ary tree that is 3 in height and has 76 leaves.
There would be one node at the root, 19 child nodes at the second level, and [tex]19^{2}[/tex] = 361 child nodes at the third level, for a total of 361 + 19 = 380 nodes in a full 4-ary tree with 76 leaves and height 3. As a result, there is a full 4-ary tree that is 3 in height and has 76 leaves.
A full 19-ary tree with 76 leaves and height 3 would have a single node at the root, four children at the second level, and four and a half children, or 16 at the third level, for a total of 16 + four and a half and twenty nodes. As a result, there is a full 19-ary tree that is 3 in height and has 76 leaves.
A full 38-ary tree would contain a single node at the root, two child nodes at the second level, and two and a half child nodes at the third level, for a total of four + two + six nodes. Consequently, there is a complete 38-ary tree that is 3 in height and has 76 leaves.
There would be one node at the root, one child node at the second level, and [tex]1^{2}[/tex]= one child node at the third level, for a total of 1 + 1 = 2 nodes in a full 76-ary tree with 76 leaves and height 3. Consequently, there is a full 76-ary tree with 76 leaves and a height of 3.
As a result, for m = 2, 4, 19, 38, and 76, a full m-ary tree with 76 leaves and height 3 exists.

The LCD (Least Common Denominator) of 10t2 is 10t2. To determine the equivalent expression is the sum of the fractions is 8t2.
A/B = C/D
Where A and B are the two fractions, and C and D are the equivalent fractions.
We will use this formula to determine the equivalent expression of the given fractions:
3t/20 = C/10t2
We can solve for C by multiplying both sides by 10t2, yielding:
30t2/20 = C/10t2
We can solve for C by multiplying both sides by 10t2, yielding:
30t2/20 = C/10t2
We can then simplify by cancelling out the 10t2 on the denominator, yielding:
C = 30t2/20
The equivalent expression for the given fractions is therefore 30t2/20.
To find the sum of the fractions, we first need to convert all fractions to equivalent fractions with a common denominator. In this case, the LCD is 10t2.
The equivalent expressions for the fractions are therefore:
3t/20 + 5/10t2 = 30t2/20 + 50/10t2
The sum of the fractions is then the sum of the numerators divided by the denominator, or:
30t2/20 + 50/10t2 = 80t2/10t2
We can simplify this expression by cancelling out the 10t2 on the denominator, yielding:
80t2/10t2 = 8t2

He finds the least common divisor (LCD) of 7t/5t^2 and (t + 8)/2t which 10t^2
He uses multiplication to find an equivalent expression.
7t/5t^2 = 7t/5t^2 * 2/2
= 14t/10t^2
and (t + 8)/2t = ((t + 8) * 5t)/(2t * 5t)
= (5t^2 + 40t)/10t^2
We need to find the sum 14t/10t^2 + (5t^2 + 40t)/10t^2
We know that if the base of two rational expressions a/b and c/b then the denominator of the result is same and we just add numerators i.e., a/b + c/b = (a + c)/b
So, 14t/10t^2 + (5t^2 + 40t)/10t^2
= [14t + (5t^2 + 40t)]/10t^2
= (5t^2 + 54t)/10t^2

Given right triangles efg and hjk. find the value of a that satisfies the congruency of the triangles. in two or more complete sentences, explain the relevance between the congruency of the triangles and the calculations made in finding the value of a.
The given triangles GEF and HKJ are congruent by the AAA test of congruency and the value of a = √2.
The two triangles are proved to be congruent and the value of a is to be determined.
Both triangles are right-angled triangles.
We know that similar triangles are those triangles that have similar properties,i.e. angles and proportionality of sides.
In triangle GEF,
since the sum of the angles in a triangle is 180
∠ G + ∠ F + ∠ E =180
90 + 45 + E = 180
∠ E = 45
similarly, ∠ J = 45
In Triangle GEF and Triangle HKJ,
∠ G = ∠ K (both are 90)
∠ F = ∠ H (both are 45)
∠ E = ∠ J (both are 45)
So, Triangle GEF and Triangle HKJ are congruent triangles by AAA congruency.
Now in triangle GEF,
cos 45 = 3a/6

a = √2
Thus, the given triangles are congruent by AAA . and the value of a = √2.

E) The null space of a 3 × 6 matrix cannot have dimension 2.
F) If A is 5x4 and null(A) = x for some column x ≠ 0, dim(im A) cannot be 2.
Matrix Linear Independence RulesA) A 3 × 4 matrix can have independent columns but not independent rows. This is because a column vector can be linearly independent, meaning no linear combination of other columns in the matrix can create it, but a row vector can't be linearly independent because it can always be written as a linear combination of the columns.
B) If A is 4 × 3 and rank A = 2, it cannot have independent columns but it can have independent rows. This is because if rank A = 2, the number of linearly independent columns is 2, which is less than the number of columns, meaning that not all columns can be linearly independent. However, since rank A = 2, the number of linearly independent rows is also 2, which is less than the number of rows, meaning that some rows can be linearly independent.
C) If A is an mxn matrix and rank A = m, it follows that m ≤ n. This is because the rank of a matrix is the maximum number of linearly independent columns, which cannot be greater than the number of columns.
D) A nonsquare matrix can have its rows independent and its columns independent, as long as the number of rows is not equal to the number of columns.
E) The null space of a 3 × 6 matrix cannot have dimension 2. This is because the dimension of the null space is always less than or equal to the number of columns of the matrix, which is 6 in this case.
F) If A is 5x4 and null(A) = x for some column x ≠ 0, dim(im A) cannot be 2. This is because the dimension of the image of A is equal to the rank of A, which cannot be less than the dimension of the null space. Therefore, dim(im A) must be greater than or equal to the dimension of the null space, which is at least 1.

The relationship between altitude and the boiling point of a liquid is linear. At an altitude of 8100 ft, the liquid boils at 197.04°F. At an altitude of 4500 ft, the liquid boils at 202.8°F. Write an equation giving the boiling point b of the liquid, in degrees Fahrenheit, in terms of altitude a, in feet. What is the boiling point of the liquid at 2300 ft?
Write an equation.
b= ??
The equation giving the boiling point b of the liquid, in degrees Fahrenheit, in terms of altitude a, in feet is b = -0.0016a + 210
The boiling point of the liquid at 2300 ft is 206.32°F
How to determine the equation giving the boiling point b of the liquidFrom the question, we have the following parameters that can be used in our computation:
At an altitude of 8100 ft, the liquid boils at 197.04°F. At an altitude of 4500 ft, the liquid boils at 202.8°FThese parameters mean that
(a, b) = (8100, 197.04) and (4500, 202.8)
The relationship is a linear equation
So, we have
slope = (b2 - b1)/(a2 - a1)
Substitute the known values in the above equation, so, we have the following representation
slope = (202.8 - 197.04)/(4500 - 8100)
Evaluate
slope = -0.0016
The equation is then represented as
b = slope * a + c
Using one of the points, we have
197.04 = -0.0016 * 8100 + c
So, we have
197.04 = -12.96 + c
Evaluate
c = 210
This gives
b = -0.0016a + 210
What is the boiling point of the liquid at 2300 ft?This means that
a = 2300
So, we have
b = -0.0016 * 2300 + 210
Evaluate
b = 206.32
Hence, the boiling point is 206.32°F

How do you dilate a line segment by 1 2?
In order to dilate a line segment by 1/ 2, every coordinate point of the end point of the line segment is multiplied by the scale factor ½.
Dilation refers to a process of changing the size of an object or shape by either increasing or decreasing its dimensions by some scaling factors. It is a type of transformation, which is used to resize the object, making the objects larger or smaller. This transformation produces an image that is the same in shape as the original but there is a difference in the size. A dilation should either stretch or shrink the original shape and is expressed by the term “scale factor.”
When a dilation creates a larger image, it is called enlargement and when a dilation creates a smaller image, it is called reduction. If the scale factor is 1/2, every coordinate point of the original segment line is multiplied by the scale factor 1/2.

The number of blue tickets is 50 tickets. The result is obtained by using the concept of operation with fractions.
How to add or subtract fractions?Find the least common denominator.Write the equivalent fraction with the least common denominator.Add or subtract the nominator without changing the denominator.In a hat, we have:
1/10 of the tickets are green.1/2 of the tickets are white.1/4 of the tickets are blue.The remaining, 30 tickets are pink.Find the number of blue tickets!
Let's say all tickets is a. Then,
Green tickets = 1/10 aWhite tickets = 1/2 aBlue tickets = 1/4 aThe remaining section (pink tickets) is
= 1 - (green + white + blue) tickets
= 1 - (1/10 + 1/2 + 1/4)
= 1 - (2/20 + 10/20 + 5/20)
= 20/20 - 17/20
= 3/20
All tickets are
3/20 = 30/a
a = (20 × 30)/3
a = 20 × 10
a = 200 tickets
The blue tickets are
= 1/4 a
= 1/4 (200)
= 50 tickets
Hence, the blue tickets in the hat are 50 tickets.
