Answer:
1080 total inches of ribbon. 60 pieces of ribbon can be cut.
Step-by-step explanation:
Firstly, the dressmaker has 15 rolls of ribbon that are 6 feet in length. Multiply those to see how many feet in total, 90. Then multiply this by 12 (there are 12 inches in a foot) to get the amount of total inches: 1080.
This is the answer to the question below the problem.
To answer the bigger question at hand:
You would need to take 1080 divided by 18 to find how many pieces the dressmaker can cut. She can cut exactly 60 pieces from her 15 rolls of ribbon.

Round 4,929 to the place value of the underlined digit.
Raising 4,929 to the place value of the underlined digit will give a value of 4930.
What is rounding up of numbers?It should be noted that rounding up of numbers simply means raising the number to the nearest ten, hundred, or thousand.
In this case let's assume that the underlined number is 2. Therefore, raising 4929 will give 4940. It should be noted that the number beside it is more than 5. Therefore, 1 will be added to 2 making 3. The new number is 4930.

What is the remainder of the quantity 4 x cubed minus 20 x minus 50 end quantity divided by the quantity x minus 3 end quantity? Show all necessary steps.[tex]\frac{4x^{3}-20x-50 }{x-3}[/tex]
The remainder of the polynomial 4x³-20x-50 / (x - 3) would be the expression 4x²+20x+52.
What is a polynomial?A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers. A polynomial can have more than one term.
We have to determine the remainder of the quantity 4 x cubed minus 20 x minus 50 end quantity divided by the quantity x minus 3 end quantity.
4x³-20x-50 = (4x³-4x²-16x-50) + (4x²+16x)
Divide both sides by (x - 3) to get
4x³-20x-50 = (4x³-4x²-16x-50)/(x-3)+(4x²+16x)/(x-3)
⇒ 4(x²+4x+12)+(4x²+16x)/(x-3)
⇒ 4x²+16x+48+(4x²+16x)/(x-3)
⇒ 4x²+16x+48+4(x+4)
⇒ 4x²+20x+52
Therefore, the remainder of the polynomial 4x³-20x-50 / (x - 3) would be the expression 4x²+20x+52.

⇒ -6 > 5 (on subtracting 8s from both sides)
the last statement shows that variables cancel out from both sides of the inequality and we get -6>5 which is not possible. Because -6>5 is not possible or false, hence no value of s will be able to satisfy the given inequality. Thus the answer for s is NO SOLUTION.

5. Please find attached the combined graph of the two functions
The similarity is the common slope
The difference is the y–intercept
What is the slope of a straight line graph?The slope is the ratio of the rise to the run of the graph.
The given function is; 2•x + 3•y = 1470
Where;
x = The number of sandwich sold
y = The number of wraps sold
The profit per sandwich sale = $2
Profit per each wrap sale = $3
1. The slope and intercept form is; y = m•x + c
Where;
m = The slope
c = The y–intercept
Therefore, 2•x + 3•y = 1470 gives;
3•y = 1470 - 2•x
y = (1470 - 2•x)÷3 = 490 - (2/3)•x
[tex] \displaystyle{y = \frac{1470-2\cdot x}{3} = 490 - \frac{2}{3} \cdot x}[/tex]
Therefore;
[tex] \displaystyle{y = 490 - \frac{2}{3} \cdot x}[/tex]By comparison, we have;
The slope, m = -2/3The y-intercept, c = 4902. Using the slope and intercept method to graph the line involves the following steps.
Mark the point (0, 490) on the graph to represent the y–interceptFrom the point (0, 490), move 2 units downwards and 3 units to the right to represent the slope of (-2/3) then mark a point at the location arrived at, which is (3, 488)Join the two points and extend the line to complete the graph3. The equation in function notation is; [tex] \displaystyle{f(x) = 490 - \frac{2}{3} \cdot x}[/tex]
The meaning of the function is that the number of wraps sold is given by the difference between 490 and two thirds of the number of sandwiches sold, or that as the number of sandwiches sold increases by by 1, the number of wraps sold decreases by 2/3

Mimi is building a decorative fence around her garden. The first fence board will be 2 feet tall, and each successive fence board will be 25% taller than the previous fence board. If Mimi plans to have 10 fence boards, is the sequence that represents the height, in feet, of the decorative fence boards finite or infinite? Is the sequence arithmetic or geometric? Explain.
The sequence of the decorative fence boards would be 66.48 feet which is the infinite geometric sequence.
What is geometric series?The geometric series defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.
The nth term of a geometric progression is expressed as
Tₙ = arⁿ⁻¹
Where a is the first term, r is the common ratio
The first fence board will be 2 feet tall, and each successive fence board will be 25% taller than the previous fence board which is given in the question.
aₙ = arˣ⁻¹ (n ≠ 0)
a₁ = 2

In the given groups of Relative Frequencies the best represented by a pie chart would be Option D. 25%; 24%; 26%; 25%.
What are Relative Frequencies?Relative frequencies are more commonly used because they allow you to compare how frequently values occur relative to the overall sample size. They are calculated by dividing the total number of responses by the number of responses for each category. Pie charts depict relative frequencies by showing how much of the total pie each category represents. Raw frequencies and relative frequencies can be displayed in frequency tables and bar charts.
According to the question we can get,
25% = [tex]\frac{1}{4}[/tex]
[tex]\frac{1}{4}[/tex] × 360° = 90°
24% approach 25%

suppose f(x)=4x-2 and g(x)=-2x+1
find the value of f(3)/g(-4)
Answer:
10/9
Step-by-step explanation:
We can calculate f(3) and g(-4)
f(3) = 4*3 - 2 = 12 - 2 =10
and g(-4) = -2 * (-4) + 1 = 8 + 1 = 9
Then it is easy to calculate f(3)/g(-4):
f(3)/g(-4) = 10/9
where we use the values which we calculated before.
⇒In the equation f(x) given f(3) plug in the value 3 in the place of x and simplify
[tex]f(3)=4(3)-2\\f(3)=12-2\\F(3)=10[/tex]
⇒For g(-4) in the place of x plug in -4 in the equation of g
[tex]g(-4)=-2(-4)+1\\g(-4)=8+1\\g(-4)=9[/tex]

The 95% confidence interval for the mean of the population lies between
(17.61, 62.39)
Construct a 95% confidence interval for the mean:
To construct a 95% confidence interval for the mean of the population, we must start with finding the following:
Mean
n=4
Mean=(25+47+32+56)/n
=(160)/4
=40
Mean is 40
Standard deviation σ
= [tex]\frac{1}{n-1}( \sum x^{2} -n(mean)^{2} )[/tex]

σ= 14.07
Now, we construct 95% confidence interval CI:
Confidence interval=mean± t-table value*(standard deviation/√n)
Given a t-table value of 3.1824 from z-distribution table, mean=40, n=4, and standard deviation=14.07, we have:
Confidence interval=(40±3.1824(14.07/√4)

volume=length x width x height
volume=3 ft * 3 ft * 1 ft=9 ft³
Therefore:
A machine can fill 9 ft³ in 3 seconds.
2) we calculate the volume of the second carton.
volume=length x width x heigth

Step-by-step explanation:
We have from #14 that
T = r + nh
where T = amount charged, n = hours worked, r = fixed rate and h = hourly rate
Subtract r from both sides:
T - r = r + nh - r
The r terms on RHS of the equation cancel out
T - r = nh
Divide both sides by n:
(T - r)/n = h
Or we can write it as
h = (T - r)/n
If r = 20, , T = 200 and n =4 we get by substitution
h = (200-20)/4
h = 180/4
h = 45
So hourly rate = $45
Before the pandemic liana can sanitize their guest room in 45minutes, and gab her brother can do the work in 30 minutes how long will take them finish the same work
They will together take 18 minutes to finish the sanitization work together.
It is mentioned that Liana can sanitize the guest room in 45 minutes only and Gab, her brother, can do the same in 30 minutes.
Let they take y minutes to finish the work together.
Let the total work be m
Workdone by Liana in 45 mintues = m
∴Workdone in 1 minute = m / 45
Workdone by Gab in 30 minutes = m
∴Workdone by Gab in 1 minute = m / 30
Let the total time taken by them = x minutes.
Total time taken by them together = m / 45 + m / 30
∴ [tex]\frac{m}{45} +\frac{m}{30} = \frac{m}{x}[/tex]
⇒ [tex]\frac{1}{45} +\frac{1}{30} = \frac{1}{x}[/tex]
LCM of 45 and 30 is 90
⇒ [tex]\frac{2}{90} +\frac{3}{90} = \frac{1}{x}[/tex]
⇒ [tex]\frac{5}{90}= \frac{1}{x}[/tex]
⇒ [tex]\frac{1}{18}= \frac{1}{x}[/tex]
⇒ x = 18 minutes
Hence they both can do the same given work in 18 mintues.
