The measure of an angle is 18°. What is the measure of its supplementary angle?
Answers
Answer:
162
Step-by-step explanation:
180 - 18 = 162
A supplementary angle equals 180 degrees
Answer:
72 degrees
Step-by-step explanation:
Supplementary angles are angles that when added together make a right angle, or 90 degrees. So 90-18=72.

Given the following situation, determine if the data is rank data. A NFL Stadium manager wants to compare the Customer Satisfaction levels of two different stadium locations. He randomly selects 30 customers from Stadium A and Stadium B, and he compares the results. The Customer Satisfaction Survey measures responses as "Highly Satisfied", "Satisfied", "Neither", "Unsatisfied", and "Highly Unsatisfied." Is this rank data? Group of answer choices not rank data rank data
Answers
Answer:
Rank data
Step-by-step explanation:
Ranked data scale is one in which the ordering or levels in the scaling format follows or depicts a certain degree of importance or hierarchy. They are usually used in ordinal scaling method. In the scenario above, the ranking follows a defined order with the highest level of satisfaction which a customer can report being Highly Satisfied" followed by "Satisfied" then "Neither" (meaning that customer is neither satisfied nor unsatisfied) the least level of satisfaction which a customer could report is being "Highly Unsatisfied." which is worse than being "Unsatisfied".

(Constructed Response) Determine whether the binomial, 9x² - 49, is a difference of
two squares. If so, factor it. If not, explain why.
Answers
Answer: It is a difference of two squares, and it factors to (3x-7)(3x+7)
=============================================================
Explanation:
We can write the 9x^2 as (3x)^2 since
(3x)^2 = (3x)*(3x) = (3*3)*(x*x) = 9x^2
The 49 can be written as 7^2 because 7^2 = 7*7 = 49.
This means 9x^2 - 49 is the same as (3x)^2 - 7^2. We have a difference of two squares.
The difference of squares factoring rule is
a^2 - b^2 = (a-b)(a+b)
which we have a = 3x and b = 7 in this case
So,
a^2 - b^2 = (a-b)(a+b)
(3x)^2 - 7^2 = (3x-7)(3x+7)
9x^2 - 49 = (3x-7)(3x+7)
Side note: This is the same as (3x+7)(3x-7). We can multiply two numbers in any order.

Answer:
The angle measures of quadrilateral P'R'S'T are equal to the corresponding angle measures of quadrilateral PRST
Step-by-step explanation:
The transformation rule (x,y) ----> (x + 4 , y + 9 ) is an example of translation.
Translation is moving the points around.
During a translation the only thing that changes is the location of the points.
Everything else stays the same therefore the corresponding angles will be congruent.

please help find the central angle and perimeter !
Answers
Step-by-step explanation:
We will have the following
*First: We have that the area of a sector of a circle is given by the expression:
A = r²a/2
Here r is the radius and alpha is the central angle.
*Second: We determine the central angle as follows:
[tex]36\pi =[/tex]
(12)²a/2 ➡️ a = 36í•2/(12) ²➡️
[tex]a = \frac{1}{2} \pi[/tex]
So, the central angle has a measurement of 1/2 pi.
Third: We determine the perimeter of the sector as follows:
First: we determine the arc length with two times the radius, that is:
p = 2(12) +
[tex]6\pi[/tex]
➡️ p = 24 +
[tex]6\pi[/tex]
So, the perimeter of the sector is 24+ 6pi meters [ Approximately 43 meters].

At a local college, 101 of the male students are smokers and 909 are non-smokers. Of the female students, 270 are
smokers and 630 are non-smokers. A male student and a female student from the college are randomly selected for a
survey. What is the probability that both are non-smokers?
Do not round your answer. (If necessary, consult a list of formulas.)
Answers
Answer:
63% Chance
Step-by-step explanation:
Remember, to find the probability of non smokers, we must find the percentage of both male and female non-smokers, and multiply them together.
So lets take all our data from this word problem first. 101 males are smokers, 909 males are not. 270 females are smokers, 630 are not.
Now, to find the percentage of non-smokers, lets add up the total amout of males, and then divide the amount of non-smokers by that number:
909+10=
1010
Ok now we know the total amount of males. Lets divide the amount of non-smokers my 1010:
909/1010
=
0.9
So this shows you that 90% of males are non-smokers.
Now lets do the same with the females:
630+270
=
900
Ok, now we know the total amount of females. Lets divide the amount of non-smoking females by this number:
630/900
=
0.7
Ok, so now we know that 70% of females are non-smokers.
Here is the final step, multipling the numbers together to find the chances of both genders being non-smokers.(I put the percentages back into decimal form when i multiplied)
0.7x0.9
=
0.63
So now we have our answer. We know that there is a 63% chance that the survey will be about 2 nonsmoking male and females.

A man can row at 9km/h in still water. He rows 1.5km upstream and back again. The stream flows at 3km/h. What is his average speed for the whole trip?
Answers
Answer:
8km/h
Step-by-step explanation:
The computation of the average speed is shown below:
In the case of upstream, the speed is
= 9 - 3
= 6km/h
And, the time would be
= 1.5km ÷ 6
= 0.25h
In the case of downstream, the speed is
= 9 + 3
= 12
The time would be
= 1.5km ÷ 12
= 0.125h
Now the average speed is
= 3 ÷ (0.25 + 0.125)
= 8km/h
Paulo has a receipt from a restaurant. The total amount is blurred, but he knows he left a $4.25 tip, which was 20% of the cost of the meal. How much did his meal cost? How much did he spend in total?
Answers

$21.25
Step-by-step explanation:
20% of the meal (x) = 4.25

0.2 * x= 4.25
0.2x= 4.25
(divide both sides by 0.2)
