Five less then f
f-5
The expression for the number of pineapples Filip has, given that Francesca has 'f' pineapples and that she always has 5 more than Filip, is 'f - 5'. This algebraic expression signifies that Filip will always have five less than whatever amount Francesca has.
Explanation:The subject of your question relates to algebraic expressions, which is an essential concept in Mathematics. To create an expression that represents the number of pineapples that Filip has, we need to understand the relationship provided in the question, which is that Francesca has five more pineapples than Filip. If Francesca has 'f' pineapples, we can express the number of pineapples Filip has as 'f - 5' because Filip will always have five less than whatever amount Francesca has.
Here's why that is: Let's say Francesca has 10 pineapples. According to the question, Filip would have 10 (Francesca's pineapples) - 5 (since he has 5 less) = 5 pineapples. No matter how many pineapples Francesca has, if you subtract five from it, you get the number of pineapples that Filip has.
This example demonstrates how algebraic expressions are used to represent relationships or scenarios mathematically. Remember, 'f - 5' is the simplified form of the expression, and it illustrates the consistent difference of 5 pineapples between Francesca and Filip.

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."

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.

[tex]F=32+\frac{9}{5} C[/tex]
Where, F is temperature in degree fahrenheit and C is temperature in degree celsius.
Since it is given that the temperature is -62 degree celsius. So put [tex]c=-62[/tex] in the above formula.
[tex]F=32+\frac{9}{5} (-62)[/tex]
[tex]F=32+\frac{(-558)}{5}\\F=32-111.6\\F=79.6[/tex]
Hence the value of temperature is -79.6 degree fahrenheit.
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

the length of a rectangle is 5 less than twice its width. if the perimeter is 26 meters, find the dimensions of the rectangle
The width of the rectangle is 6 meters and the length is 7 meters.
Explanation:To solve this problem, let's assume that the width of the rectangle is represented by w. The length of the rectangle can be written as 2w - 5. The perimeter of a rectangle is given by the formula P = 2l + 2w, where P represents the perimeter, l represents the length, and w represents the width. We are given that the perimeter is 26 meters, so we can set up the equation:
26 = 2(2w - 5) + 2w
Simplifying this equation gives:
26 = 4w - 10 + 2w
Combining like terms:
26 = 6w - 10
Adding 10 to both sides:
36 = 6w
Dividing both sides by 6:
w = 6
Therefore, the width of the rectangle is 6 meters. To find the length, substitute the value of w back into the expression for the length:
l = 2w - 5
l = 2(6) - 5
l = 7
So the dimensions of the rectangle are width = 6 meters and length = 7 meters.

The problem is solved by setting up an algebraic equation based on the given pointers about the rectangle's width, length, and perimeter. After solving it, we find that the rectangle's dimensions are: width=6 meters and length=7 meters.
Explanation:
This is a problem of algebra within the subject of Mathematics. The width and length of the rectangle are the unknowns we need to find.
Given in the problem, the length is '5 less than twice its width'. If we denote the width as 'x', the length can be expressed as '2x - 5'. The equation for the perimeter of a rectangle is '2(length + width)', which equals 26 in this case. So we can set up our equation as follows: 2(x + 2x - 5) = 26.Solving this equation step-by-step:
Firstly, unfold the parentheses - 2x + 4x - 10 = 26, Then combine like terms to simplify it into 6x - 10 = 26. Add 10 to both sides of the equation to isolate the term with 'x', which results in 6x = 36. Finally, divide by 6 on both sides to find the value of 'x', so x=6. Substituting x=6 into the expression for the length, we find the length to be 2*6 - 5 = 7.Therefore, the dimensions of the rectangle are width=6 meters and length=7 meters.

the highest average is 0.368
Answer:
0.368 is the highest average.
Step-by-step explanation:
We have been given the batting averages of the 4 top players on one major league team as 0.332, 0.361, 0.343, and 0.368. We are asked to choose the highest average from given choices.
Let us represent our given averages as fractions as:
[tex]\frac{332}{1000},\frac{361}{1000},\frac{343}{1000},\frac{368}{1000}[/tex].
Now we can see that 1st player hit 332 in 1000 at bats, 2nd player hit 361 in 1000 at bats, 3rd player hit 343 in 1000 at bats and 4th player hit 368 in 1000 at bats.

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.
