Point Q is the midpoint of segment PR. QR = 18 and PR = 5x+6.
Answers
Applying the definition of the midpoint of a segment, we have:
x = 6
PR = 36 units
What is the Midpoint of a Line Segment?If point Q is the midpoint of segment PR, it therefore means that point Q bisects (divides) line segment PR into two equal parts, namely: PQ = QR.
Also, PQ + QR = PR
Given the following:
QR = 18
PR = 5x + 6
Thus, we can create the following equation:
2(QR) = PR
Substitute
2(18) = 5x + 6
36 = 5x + 6
36 - 6= 5x + 6 - 6
30 = 5x
30/5 = 5x/5
6 = x
x = 6
PR = 5x + 6
Plug in the value of x
PR = 5(6) + 6
PR = 36 units

what is the greatest common factor of 72 and 54 ?
in other words, what is the biggest number that divides both numbers without remainder ?
I use a prime factor analysis (identify all the prime factors).
72 :
72 ÷ 2 = 36
36 ÷ 2 = 18
18 ÷ 2 = 9
9 ÷ 2 no
9 ÷ 3 = 3
3 ÷ 3 = 1 finished
72 = 2⁴×3²
54 :
54 ÷ 2 = 27
27 ÷ 2 no
27 ÷ 3 = 9
9 ÷ 3 = 3
3 ÷ 3 = 1 finished
54 = 2×3³
the largest number that can divide them both without remainder is the combination of the prime factors they have in common :

b) 32cm
a) A pentagon is 6.4cm to 1 decimal place it can see that the answer.
b) A pentagon has 5 sides.
The Pentagon was originally intended to be built on ground that had five sides surrounded by roadways, therefore the architects created a five-sided structure. The Pentagon serves as the Department of Defense of the United States' administrative center. During World War II, it was built on an accelerated schedule.
Any five-sided polygon or 5-gon is referred to as a pentagon in geometry (from the Greek word pente meaning five and gonia meaning angle). In a straightforward pentagon, the interior angles add up to 540°. A pentagon could be straightforward or self-intersect. A pentagram is a self-intersecting regular pentagon (sometimes known as a star pentagon).

Argyle wants to make T-shirts for students. Customink is willing to offer a deal with the school that each shirt will cost $5 plus a $50 fee for each shirt color. Argyle wants to make a teal and a purple shirt.
Write an equation that shows the total cost (t) for the shirts (s) made on two different colors. Also explain what the variables and constraints are.
Answers
Answer:
See explanation
Step-by-step explanation:
c=different number of colors
t=5s+50c ==> c=2
t=5s+50(2)
t=5s+100
5 is the cost of making each shirt and 50 is the cost of making shirts in one color. Hence, 50c is the cost of making shirts in c number of colors and 5s is the cost of making s number of shirts. 50c translates to 50(2) since shirts are made in two colors, so 50(2)=100. 100 dollars is the total cost of making shirts in 2 different colors.

Consider the following polygon. Determine the measure of both angles A and B. Show your work. (Note: image is not drawn to scale)
Answers
Considering the sum of the internal angles of the polygon, it is found that the measures of the angles A and B are given as follows;
Angle A: 119º.Angle B: 93º.What is the sum of the internal angles of a polygon?The sum of the internal angles of a polygon with n vertices is given by the following equation:
S = (n - 2) x 180º.
For this problem, the polygon has 6 vertices, hence n = 6 and the sum is given by:
S = (6 - 2) x 180º = 720º.
Considering each internal angle, we can solve for x as follows:
13x + 2 + 16x + 7 + 88 + 155 + 170 + 95 = 720
29x + 517 = 720
29x = 203
x = 203/29
x = 7.
Then the measures are given as follows:
Angle A: 16 x 7 + 7 = 119º.Angle B: 13 x 7 + 2 = 93º.More can be learned about the sum of the internal angles of a polygon at https://brainly.com/question/224658

The correct answer is 5.5.
Numerator and denominator are the two components of a fraction. The denominator, which is not zero, comes below the line dividing the numerator from the denominator.
The simplest way to answer this question is to multiply the mixed number and fraction together after converting them to decimals.
We are aware that we must divide the numerator by the denominator in order to convert a fraction to a decimal.
1 ÷ 3 Equals 0.3... (This decimal repeats itself.)
0.3... + 7 Equals 7.3... (Continues to repeat)
7/3 equals 7.(3) in decimal form.
3 ÷ 4 = 0.75
As a decimal, 3/4 is 0.75.

Answer:
A. 26 = 13.5 + m/2.5; m = 5 is the correct equation and solution.
To explain, the word "quotient" indicates that we need to divide a number by 2.5. Let the unknown number be represented by the variable "m". Then, the quotient of a number and 2.5 can be written as m/2.5. The math sentence can be written as: 26 = 13.5 + m/2.5
To solve for "m", we can isolate it by subtracting 13.5 from both sides and then multiplying both sides by 2.5:
26 - 13.5 = m/2.5
12.5 = m/2.5
m = 12.5 * 2.5
m = 5
Therefore, the equation that represents the given math sentence is 26 = 13.5 + m/2.5, and the solution is m = 5. Option a is correct.

Using the normal distribution, the z-score of the height of a women 5.5 feet tall is 0.51.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.Considering that each feet has 12 inches, the parameters are given as follows:
[tex]X = 5.5 \times 12 = 66, \mu = 64.1, \sigma = 3.7[/tex]
Hence the z-score is found as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (66 - 64.1)/3.7
Z = 0.51

What is the y-intercept of a function?The y-intercept of a function is the value of f(x) when x = 0, that is, the value of y for which the function crosses the y-axis.
If the function crosses the y-axis at y = 0, it will have a y-coordinate of 0, hence:
