How many sides do 2 octagons, 4 pentagons, and 5 triangles have in all?
Answer: 51
Step-by-step explanation:
2 octagons have 16 sides because an octagon has eight sides. So, 8x2=16.
4 pentagons have 20 sides because a pentagon has 5 sides. So, 4x5=20.
5 triangles have 15 sides because a triangle has 3 sides. So, 5x3=15.
In all, 16+20+15= 51

Students in an Algebra 1 class will perform the following experiment and then model it mathematically. They begin with 128 two-colored counters (a chip that has a yellow side and a red side) in a bag and complete the following steps:
Pour the counters from the bag onto the floor.
Count the number of counters that land on yellow.
Record the trial number and the number of counters that landed on yellow.
Put the counters that landed on yellow back into the bag and leave the rest on the floor (off to the side).
Steps 1 to 4 constitute one trial of the experiment. Repeat trials until no counters land on yellow.
Question 1
POSSIBLE POINTS: 1
Part A
Select the equation that best represents f(n), the number of yellow counters that land on yellow (and are put back into the bag) at the end of trial n, when n≥1?
A f(n)=128(12)nf of n is equal to 128 times 1 half to the n th power
B f(n)=128−12nf of n is equal to 128 minus 1 half n
Question 2
Part B
How many trials would the students most likely need to run until exactly one counter lands yellow side up (and is put into the bag)? Use mathematics to justify your response.
The number of counters is an illustration of a linear function
The number of counters that land on yellow is: [tex]f(n) = 128 - \frac 12n\\[/tex]The students need 254 trials to have one yellow side upHow to determine the equation
The number of counters is given as:
Count = 128
Each counter is two-colored (i.e. 1/2 yellow and 1/2 red)
So, the equation that represents the number of counters that land on yellow is:
[tex]f(n) = 128 - \frac 12n\\[/tex]
The number of trials to have one yellow side upWhen one yellow side is up, we have:
f(n) = 1
So, we have:
[tex]1 = 128 - \frac 12*n[/tex]
Subtract 128 from both sides
[tex]-127 = - \frac 12*n[/tex]
Multiply both sides by -2
[tex]n =254[/tex]
Hence, the student needs 254 trials to have one yellow side up

What is0.54¯¯¯¯ expressed as a fraction in simplest form?
Enter your answer in the box.
Answer:
0.54 as a fraction is 54/100 and simplified it would be 27/50
Answer:
27 / 50
Step-by-step explanation:
You can find this out by re-stating it as 54 / 100 and removing common factors between the numerator and denominator. In this case, only the number 2 can be factored out:
54 / 100
= 27 / 50
27 is a perfect cube (three cubed), and 50 is not divisible by 3, so we can't factor it further.
Find a polynomial f(x) of degree 5 that has the following zeros. 1, 8, -7, 5, -4. Leave your answer in factored form
Answer:
f(x) = (x-1) (x-8) (x +7)(x-5) ( x+4)
Step-by-step explanation:
The zeros of the function are written in the form
f(x) = (x-a)(x-b)..... where the a,b are the zeros
f(x) = (x-1) (x-8) (x - -7)(x-5) ( x--4)
Rewriting
f(x) = (x-1) (x-8) (x +7)(x-5) ( x+4)

The data modeled by the box plots represent the battery life of two different brands of batteries that Mary tested. A) What is the median value of each data set? B) Compare the median values of the data sets. What does this comparison tell you in terms of the situation the data represents? ( Answer A and B) Will Mark Brainliest if correct answer.
Answer:
Part A:
Median value for Brand X = 13
Median value for Brand Y = 16
Part B: Brand Y has a longer battery life
Step-by-step explanation:
Part A:
Median value is depicted on a box plot by the vertical line that divides the rectangular box. Therefore:
Median value for Brand X = 13
Median value for Brand Y = 16
Part B:
Brand Y has a higher median value (16) than Brand X (13).
This implies that brand Y has a battery life that last longer than brand X.
Answer:
Brand X median: 13
Brand Y median: 16
Brand Y has a longer battery life than Brand X.

Sharon wants to put lace around the edge of the circular mirror shown.
12 in.
C = TD, where C is the circumference, and D is the diameter. Use 3.14 for the value of .
How many inches of lace will Sharon need to cover the edge of the mirror exactly once?
A. 3.82 in.
B. 18.84 in.
C. 37.68 in.
D. 75.36 in.
Answer:
37.68in
Step-by-step explanation:
Circumference = πd
d is the diameter = 12in
To get the number of lace that will cover we will find the circumference
C = 12 * 3.14
C = 37.68in
Hence the amount of lace needed is 37.68in
find the slope of the line through each pair of points (19,-2) (-11,10)
Answer:
[tex]\huge\boxed{-\frac{2}{5}}[/tex]
Step-by-step explanation:
The slope of a line can be determined from two points via the slope formula. This is usually defined as the change in y divided by the change in x. It’s commonly represented using this formula:
[tex]\displaystyle \frac{\Delta y}{\Delta x}[/tex]Where [tex]\Delta[/tex] represents “change in.”
The slope is basically just saying the rate of increase/decrease a function has when x increases by 1 - how much does y change when x increases by 1? We can find this by taking larger values and dividing by the rate at which we took the larger values. This derives the slope formula.
We can find the change in y and x in this function by analyzing the two points given. If we look at the change between each point, we can get the change since this is a line and thus has a constant slope.
The change in y will be 12. This is because from -2 to 10 is 10 units - [tex]10 - (-2) = 12[/tex] The change in x will be -30. This is because from 19 to -11 is -30 units - [tex]-19 -11 = -30[/tex]Now that we have our change in x and y, we can substitute these values into the slope formula.
[tex]\displaystyle \frac{\Delta y}{\Delta x}[/tex] [tex]\displaystyle \frac{12}{-30}[/tex] [tex]\displaystyle -\frac{12}{30}[/tex] Simplify - divide numerator and denominator by 6 [tex]\displaystyle -\frac{2}{5}[/tex]Therefore, the slope of this line is [tex]-\frac{2}{5}[/tex].

Your local dry cleaners is running a special. The dry cleaner is offering a 13% discount for any drop off that is over $40. Also, they are running a neighborhood special of an additional 5% off. Given this information, determine the decay factor corresponding to each percent decrease.

34.8; 33.06
c.
0.87; 0.95
b.
0.384; 0.3306
d.
87; 95
Answer:
a. 34.8; 33.06
Step-by-step explanation:
The computation is shown below;
since in the question it is mentioned that that if the price is $40 so if offered the 13% discount
So the 13% discount on $40 is
= $40 - 13% of $40
= $34.80
Now additional 5% is also provided
So,
= $34.80 - 5% of $34.80
= $33.06

65 people use the track.
27 people use the gym and the pool.
23 people use the pool and the track.
31 people use the gym and the track.
4 people use all three facilities.
How many people use at least two facilities
Answer: 54 people
Step-by-step explanation:
Given:
There are 135 people.
There are 3 facilities - Gym, Swimming Pool and Track.
Gym = 77
Swimming Pool = 62
Track = 65
Gym and pool = 27
Pool and track = 23
Gym and track = 31
All 3 facilities = 4
To FInd:
The number of people who use exactly one facilities.
Explanation:
Such question is easiest solved by using a Venn diagram. See attached.
Solution:
Find the number of people who goes to Gym and Swimming Pool only:
Gym and Swimming Pool only = 27 - 4
Gym and Swimming Pool only = 23
Find the number of people who goes to Swimming Pool and Track only:
Gym and Swimming Pool only = 23 - 4
Gym and Swimming Pool only = 19
Find the number of people who goes to Gym and Track only:
Gym and Swimming Pool only = 31 - 4
Gym and Swimming Pool only = 27
Find the number of people who goes to Gym only:
Gym only = 77 - 23 - 27 - 4
Gym only = 23
Find the number of people who goes to Swimming Pool only:
Swimming Pool only = 62 - 23 - 19 - 4
Swimming Pool only = 16
Find the number of people who goes to Track only:
Track only = 65 - 27 - 19 - 4
Track only = 15
Find the total number of people who goes to one facility only:
One Facility = 23 + 16 + 15
One Facility = 54
Answer: 54 people.

What are the period and amplitude of the function?
period: 4; amplitude: 3
period: 4; amplitude: 2.5
period: 5; amplitude: 3
period: 5; amplitude: 2.5
The period is the distance between one peak and the next peak ( the two highest points)
One peak is at x= 0, the next peak is at x = 5 then the third peak is at x = 10.
Subtract to find the distance: 10-5 = 5 and 5-0 = 5 so the period is 5.
The amplitude is the distance from the centerline to the peak. First find the highest and lowest points to finch the center:
Highest = 3 lowest = -2. The distance between the highest and lowest is 5 so the centerline would be 5/2 = 2.5
The amplitude would be the distance from center to peak which would be 2.5
The answer is:
Period = 5, amplitude = 2.5
