What is the measure of an interior angle of a regular 12-gon?
a-30
b-216
c-150
d-112.5
Answer:
The measure of an interior angle of a regular 12-gon is 150°.
Hence, option 'C' is correct.
Step-by-step explanation:
We need to determine the measure of an interior angle of a regular 12-gon.
We know that the number of sides in a regular 12-gon = n = 12Thus,
Using the formula to determine the measure of an interior angle of a regular 12-gon is given by
(n - 2) × 180° = n × interior angle
substitute n = 12
(12 - 2) × 180 = 12 × interior angle
10 × 180 = 12 × interior angle
Interior angle = (10 × 180) / 12
= 1800 / 12
= 150°
Therefore, the measure of an interior angle of a regular 12-gon is 150°.
Hence, option 'C' is correct.

The City Sights tour company had the same ratio of tourists to guides on both days this weekend. On Saturday, there were 120 tourists and 18 guides. OnSunday, there were 40 tourists.
Answer: 6 guides
Step-by-step explanation:
Question wants to know the number of Guides present on Sunday.
On Saturday there were 120 tourists and 18 guides. The ratio was therefore:
120 : 18
On Sunday, the ratio must be the same and there are 40 tourists. You can solve this using direct proportion and multiplying:
120 : 18
40 : x
120x = 18 * 40
x = 720/120
x = 6 guides

Vito is picking up coffee and pastries for his friends. At a local coffee shop, each cup of coffee costs $2.50, and each pastry costs $4.00. If he buys a total of nine items at the coffee shop and spends a total of $28.50, how many pastries does he buy?
Group of answer choices
Answer: He bought 4 pastries.
Step-by-step explanation:
Let x = Number of cups of coffee
y= Number of pastries.
As per given,
x+y=9 ....(i)
2.5x+4y=28.50 ...(ii)
Multiply 4 to (i), we get
4x+4y=36 ...(iii)
Eliminate (ii) from (iii), we get
[tex]1.5x=7.5\\\\\Rightarrow\ x=5[/tex]
Put x=5 in (i) , we get
5+y=9
y= 4
Hence, He bought 4 pastries.

The box plots below show student grades on the most recent exam compared to overall grades in the class:
Two box plots are shown. The top one is labeled Class. Minimum at 70, Q1 at 74, median at 83, Q3 at 92, maximum at 100. The bottom box plot is labeled Exam. Minimum at 60, Q1 at 81, median at 87, Q3 at 91, maximum at 95.
Which of the following best describes the information about the medians?
The exam outlier at 60 makes the IQR narrower and the median higher.
The class data are more evenly spread, which pulls its median down.
The class median is lower than the exam median.
The class Q3 is lower than the exam Q3.
Answer:
The actual answer is D.
Step-by-step explanation:
The class Q3 is lower than the exam Q3,
i dont know why it is correct but my older sister said it is so I trust her
edit: Nvm the answer was wrong :(, I really don't know what the answer is
The correct description about median is class median is lower than the exam median.
What is Box plot?An illustration of variation in a set of data is called a box and whisker plot. A histogram analysis usually gives an adequate display, but a box and whisker plot can add more detail while enabling the display of different sets of data on the same graph.
We have,
Box plot 1:
Minimum= 70
Q1 = 74
Median = 83
Q3 = 92
Maximum = 100
Box plot 2:
Minimum= 60
Q1 = 81
Median = 87
Q3 = 91
Maximum = 95
So, the class median is lower than the exam median.

The ratio pages read to minutes for hang is 5 : 8. Who has the greater ratio of pages read to minutes than hang?
Answer:
Option B, C, and D
Step-by-step explanation:
This is the complete question below;
The ratio of pages read to minutes for Hang is 5 : 8. Who has a greater ratio of pages read to minutes than Hang? Select all that apply. A. Kira:2 pages read every 4 minutes B. Joe:6 pages read every 9 minutes C. Quon:5 pages read every 7 minutes D. Lulu:10 pages read every 13 minutes E.
EXPLANATION:
We are given, The ratio of pages read to minutes for Hang as 5 : 8. Which means 5/8= 0.625, then we can say he read 0.625 of a page per minute.
Let us do this for each of the given options;
A. Kira:2 pages read every 4 minutes
Kira's rate= 2/4= 0.5page per minute.
B. Joe:6 pages read every 9 minute
Then Joe's rate = 0.667page per minute.
C. Quon:5 pages read every 7 minute
Quon's rate = 5/7 = 0.7143page per minute.
D. Lulu:10 pages read every 13 minutes
Lulu's rate= 10/13= 0.76923page per minute.
Those that that has a greater ratio of pages read to minutes than Hang are
Joe(0.667page per minute)
Quon( 0.7143page per minute)
and Lulu (0.76923page per minute.)
Because their rate is higher than HANG(0.625 of a page per minute.)

Zach is 23 years old. Sax age is 3 years older than twice Maya's age. Let m represent Maya's age. Which equation can be used to solve Maya's age?
Step-by-step explanation:
Let Maya's age is m.
Sax age is 3 years older than twice Maya's age
Sax age = 2m +3
Zach age = 23 years
We need to find the equation that is used to solve Maya's age. ATQ,
2m + 3 = 23
If we solve,
2m = 23-3
2m = 20
m = 10
Hence, this is the required solution.
(PLEASE HELPPP GIVING BRAINILEST) The dot plots show the number of hours a lightbulb lasts from two different brands Which of the following statemens is correct ?
Answer:
The answer is A
Step-by-step explanation:
Answer:
C. The mean for brand B is higher than brand A.
Step-by-step explanation:
What we're looking for is the true statement of these 4.
We already know B is out, because there were 11 lightbulbs on brand B, and 10 on brand A.
Because of that, A is also out, because the means cannot be the same.
As a result, only C and D remain.
Now, add the 10 dots on brand A.
((1000 * 1) + (1100 * 2) + (1200 * 3) + (1300 * 4))/10
(1000 + 2200 + 3600 + 5200)/10
(3200 + 3600 + 5200)/10
(6800 + 5200)/10
12000/10
Brand A has an average of 1200 hours/lightbulb
Then, add the 11 on brand B
((1400 * 1) + (1500 * 4) + (1600 * 2) + (1700 * 1) + (1800 * 1) + (1900 * 1))/11
(1400 + 6000 + 3200 + 1700 + 1800 + 1900)/11
(7400 + 3200 + 1700 + 1800 + 1900)/11
(10600 + 1700 + 1800 + 1900)/11
(12300 + 1800 + 1900)/11
(14100 + 1900)/11
16000/11
Brand B has an average of 1454 hours 27 minutes 16 seconds 364 milliseconds/lightbulb
Comparing the two averages, we come to the realization that D is out because Brand A's average was less than Brand B's.
That leaves C as our answer.
