The relationship between women’s whole-number shoe sizes and foot length forms an arithmetic sequence, where an is the foot length in inches that corresponds to a shoe size of n. A women’s size 3 fits a foot 8 inches long and women’s size 7 fits a foot 91 3 inches long. What is the common difference of the arithmetic sequence?
Answer:
part 1- 1/3
part 2- a.n = 22/3+(n-1)1/3
part 3- size 12
Step-by-step explanation:
The common difference of the arithmetic sequence is 0.5 inches.
To find the common difference of the arithmetic sequence, we can use the given information about the shoe sizes and corresponding foot lengths.
Let's denote the common difference by [tex]\( d \)[/tex]. In an arithmetic sequence, the[tex]\( n \)-th[/tex] term is given by [tex]\( a_n = a_1 + (n - 1)d \)[/tex], where [tex]\( a_1 \)[/tex] is the first term.
Given that a women's size 3 fits a foot 8 inches long, we can consider this as the first term of the arithmetic sequence:
[tex]\[ a_1 = 8 \][/tex]
We are also given that a women's size 7 fits a foot[tex]\( 9\frac{1}{3} \)[/tex] inches long. Since this corresponds to the 5th term in the sequence (because [tex]\( 7 - 3 = 4 \)[/tex] and we start counting from 0), we can write:
[tex]\[ a_5 = a_1 + 4d \][/tex]
[tex]\[ a_5 = 8 + 4d \][/tex]
We know[tex]\( a_5 = 9\frac{1}{3} \),[/tex]which is [tex]\( 9 + \frac{1}{3} \) or \( \frac{28}{3} \)[/tex] inches. Now we can set up the equation:
[tex]\[ 8 + 4d = \frac{28}{3} \][/tex]
To solve for [tex]\( d \)[/tex], we first convert[tex]\( \frac{28}{3} \)[/tex] to a decimal or a fraction with a denominator of 1 to match the units of the other terms:
[tex]\[ 8 + 4d = \frac{28}{3} \times \frac{1}{1} \][/tex]
[tex]\[ 8 + 4d = \frac{28}{3} \][/tex]
[tex]\[ 8 + 4d = 9\frac{1}{3} \][/tex]
[tex]\[ 8 + 4d = 9.333... \][/tex]
Now, we solve for[tex]\( d \)[/tex]:
[tex]\[ 4d = 9.333... - 8 \][/tex]
[tex]\[ 4d = 1.333... \][/tex]
[tex]\[ d = \frac{1.333...}{4} \][/tex]
[tex]\[ d = 0.333... \][/tex]
However, we need to express[tex]\( d \)[/tex] in inches, and since [tex]\( \frac{1}{3} \)[/tex] of an inch is [tex]\( 0.333... \)[/tex]inches, we convert it to a fraction that has a denominator of 2 to match the format of the options given:
[tex]\[ d = \frac{1}{3} \times \frac{2}{2} \][/tex]
[tex]\[ d = \frac{2}{6} \][/tex]
[tex]\[ d = \frac{1}{3} \][/tex]
[tex]\[ d = 0.5 \][/tex]
Therefore, the common difference of the arithmetic sequence is[tex]\( 0.5 \)[/tex]inches."

Barbara drives between Miami, Florida, and West Palm Beach, Florida. She drives 50 mi in clear weather and then encounters a thunderstorm for the last 16 mi. She drives 18 mi slower through the thunderstorm than she does in clear weather. If the total time for the trip is 1.5 hr, determine her speed driving in nice weather and her speed driving in the thunderstorm.
Answer:
Her speed driving in nice weather is 50 mph and in thunderstorm is 32 mph.
Step-by-step explanation:
Barbara drives 50 miles in clear weather and then encounters a thunderstorm for the last 16 miles.
Suppose, her speed in nice weather is [tex]x[/tex] mph.
As she drives 18 mph slower through the thunderstorm than she does in clear weather, so her speed in thunderstorm will be: [tex](x-18) mph[/tex]
We know that, [tex]Time = \frac{Distance}{Speed}[/tex]
So, the time of driving in clear weather [tex]=\frac{50}{x}[/tex] hours
and the time of driving in thunderstorm [tex]=\frac{16}{x-18}[/tex] hours.
Given that, the total time for the trip is 1.5 hours. So, the equation will be......
[tex]\frac{50}{x}+ \frac{16}{x-18}=1.5 \\ \\ \frac{50x-900+16x}{x(x-18)}=1.5\\ \\ \frac{66x-900}{x(x-18)}=1.5 \\ \\ 1.5x(x-18)=66x-900\\ \\ 1.5x^2-27x=66x-900\\ \\ 1.5x^2-93x+900=0\\ \\ 1.5(x^2 -62x+600)=0\\ \\ x^2 -62x+600=0\\ \\ (x-50)(x-12)=0[/tex]
Using zero-product property.........
[tex]x-50=0\\ x=50\\ \\ and\\ \\ x-12=0\\ x=12[/tex]
We need to ignore [tex]x=12[/tex] here, otherwise the speed in thunderstorm will become negative.
So, her speed driving in nice weather is 50 mph and her speed driving in thunderstorm is (50-18) = 32 mph

Step-by-step explanation:
A magazine can layout 1/16 of an issue in 3 days.How many days dies it take to layout one issue?
To determine the time needed to layout a full magazine issue, multiply the time taken to layout 1/16 of an issue (3 days) by 16, resulting in 48 days total.
If a magazine can layout 1/16 of an issue in 3 days, then to calculate how many days it takes to layout one entire issue, we simply multiply the number of days it takes to layout 1/16 of the issue by 16.
This is because if 1/16 takes 3 days, then 1/8 (which is twice the amount of 1/16) would take twice as long
(3 days * 2 = 6 days),
and similarly, we can scale up to the full issue (1/1) by multiplying 3 days by 16.
The calculation would be:
Identify the portion of the issue completed: 1/16.
Identify the time taken for this portion: 3 days.
Calculate the time for the whole issue: 3 days * 16 = 48 days.
So, it would take 48 days to layout one full issue.

A supervisor finds the mean number of miles that the employees in a department live from work. He finds x=29 and s=3.6 . Which statement must be true?
z37 is within 1 standard deviation of the mean.
z37 is between 1 and 2 standard deviations of the mean.
z37 is between 2 and 3 standard deviations of the mean.
z37 is more than 3 standard deviations of the mean.
Answer:
Option 3 is right
z37 is between 2 and 3 standard deviations of the mean.
Step-by-step explanation:
Let X be a random variable which represents the mean number of miles that the employees in a department live from work
X is normal (N(29,3.6)
WE have to find Z score for X
Z =[tex]\frac{x-29}{3.6}[/tex]
=2.22
i.e. 37 is 2.22 std deviations from the mean.
In other words, z37 is between 2 and 3 standard deviations of the mean.
The z-score for z37 is approximately 2.22. This indicates that it lies between 2 and 3 standard deviations of the mean. Hence, the correct statement is: z37 is between 2 and 3 standard deviations of the mean.
To determine which statement is true regarding the z-score for the value z37, we need to calculate the z-score using the given mean and standard deviation.
We know the mean ( ext{x}) = 29 and the standard deviation (s) = 3.6.The z-score formula is z = (X - mean) / standard deviation. Here, X = 37.This means that z37 is approximately 2.22 standard deviations away from the mean. Therefore, the correct statement is:
z37 is between 2 and 3 standard deviations of the mean.
In a normal distribution, about 95 percent of the x values lie within two standard deviations, and about 99.7 percent lie within three standard deviations of the mean.

You and nine friends have decided to take a few days to go camping. You plan a budget of $50 per day for activities. On one of the days you will rent canoes and tubes to explore the river. Tube rentals cost $5 and canoes cost $10. Each person would need a tube, but canoes hold up to three people. In order to budget for your day on the river, write an equation that shows how many tubes (t) and canoes (c) you would need to accommodate your group, then write an equation that expresses how much the tubes and canoes will cost and remain within the confines of your budget. Using the equations, find how many tubes and canoes can be rented.
y=10x+5 because x=3 so 10*3=30 and 30+5=35 which would mean that $35 is the lowest amount you can spend.
To stay within a $50 daily budget for activities, equations are created to determine the number of tubes (t) and canoes (c) that can be rented. With tube rentals at $5 and canoe rentals at $10, the group of ten can only rent tubes (t = 10), as renting canoes would exceed the budget (c = 0).
The question involves creating and solving a budget constraint problem similar to the examples provided for Janet Bain and Mr. Higgins. To accommodate the group of 10 people with a budget of $50 per day for activities, we need to write equations to determine how many tubes (t) and canoes (c) can be rented. We know that tube rentals cost $5 and canoe rentals cost $10. Each canoe holds up to three people.
First, we write an equation that represents the number of tubes and canoes needed:
Everyone needs a tube: t = 10
Canoes can hold three people: 3c ≥ 10 (since not everyone needs to be in a canoe at the same time)
Next, we write an equation for the total cost to remain within the budget: 5t + 10c ≤ 50 (cost of tubes plus canoes must be less than or equal to $50)
Using t = 10, we can substitute t in the cost equation: 5(10) + 10c ≤ 50
50 + 10c ≤ 50
10c ≤ 0
From the final inequality, c = 0; meaning you cannot rent any canoes if you're buying a tube for each person and staying within a $50 budget. Therefore, the group can only rent tubes, with 0 canoes.
Describe the dilation needed to map each pre-image onto each image.
Answer:
(1)- 1/3 (2)- 2 (3)- 1/2 (4)- 4.
Step-by-step explanation:
We have been given four images and their pre-images and we are asked to find out the factor of dilation.
(1) We have been given a triangle ABC, whose center of dilation is A. In order to find out factor of dilation we will see lengths of two corresponding sides. AB is 6 units long and A'B' is two units long. To map triangle ABC on triangle A'B'C' we have to dilate triangle ABC by a factor of 1/3 as 2 is 1/3 of 6.
Therefore, factor of dilation is 1/3.
(2) Let us find the lengths of two corresponding sides of our image and pre-image. Side ST is 6 units long and S'T' is 12 units long. To map our image of quadrilateral on pre-image we have to dilate our image by a factor of 2 as S'T' is 2 times of ST.
Therefore, factor of dilation is 2.
(3) Side QR is 6 units long and its corresponding side Q'R' is 3 units long. We can see that Q'R' is 1/2 of QR so in order to map our triangle QRS on triangle Q'R'S' we have to dilate our pre-image by a factor of 1/2.
Therefore, our factor of dilation is 1/2.
(4) Length of side AB of our image is 2 units and A'B' is 8 units long. 8 is 4 times 2. To map our pre-image ABC on our image A'B'C' we have to dilate our mage by a factor of 4.
Therefore, factor of dilation is 4.

For this item, any answers that are not whole numbers should be entered as a decimal, rounded to the hundredths place. Nicole started the day with $63.44 in her bank account. Later in the day, Nicole's bank processed a check that Nicole mailed last week to pay her electric bill. When this happened, the bank deducted $186.56 from Nicole's balance which caused her account to be overdrawn. Before the bank closed, Nicole made a deposit equal to the amount her account was overdrawn. What was Nicole's bank balance at the end of the day? At the end of the day, Nicole's bank balance was how many dollars?
-92.34 is the answer
Final answer:
After Nicole's check for her electric bill was processed, her account was overdrawn. She then made a deposit equal to the overdraft amount, bringing her end-of-day balance to $0.00.
Explanation:
To determine the bank balance that Nicole had at the end of the day, we need to consider the transactions that affected her account. She started with $63.44. After her electric bill check of $186.56 was processed, her account would have been overdrawn by $186.56 - $63.44 = $123.12. To cover this overdraft, Nicole made a deposit equal to the amount her account was overdrawn. Therefore, she deposited $123.12, which brought her balance back to $0.
At the end of the day, Nicole's bank balance was $0.00.
The Fall Festival charges $0.75 per ticket for the rides. Kendall bought 18 tickets for rides and spent a total of $33.50 at the festival. She only spent her money on ride tickets and admission into the festival. The price of admission is the same for everyone. Use y to represent the total cost and x to represent the number of ride tickets.
(a) Define your variables.
(b) Write a linear equation to calculate the cost for anyone who only pays for festival admission and rides
(c) Explain your answer to Part B.
Step-by-step explanation:
The Fall Festival charges $0.75 per ticket for the rides. Kendall bought 18 tickets for rides and spent a total of $33.50 at the festival
0.75 per ticket. So cost of 18 tickets= 0.75 * 18 = $13.5
Kendall spent $13.50 for tickets . Total spent = $33.50
Total spent = ticket cost + admission cost
33.50 = 13.50 + admission
Admission cost = 33.50 - 13.50 = $20
(a) y to represent the total cost , x to represent the number of ride tickets.
'b' represents the admission cost
(b) General form of linear equation is y=mx+b
m = 0.75 and b = admission cost = 20
So equation becomes y = 0.75x + 20
(c) Initially, she has to pay the admission price $20. then 0.75 per ticket.
The value of x changes depends on the number of tickets she wants to buy.
y is the total cost she has to pay for x tickets with admission price
