A unit of measure used in surveying is the link; 1 link is about 8 inches. about how many links are there in 9 feet.
Answers
1 link = 8 inches
1 inch = 0.083 feet
108 inches = 9 feet
To find how many links:
108/8= 13.5 links
To find out how many links are there in 9 feet, we can use the conversion factor that 1 link is about 8 inches.
Explanation:To find out how many links are there in 9 feet, we can use the conversion factor that 1 link is about 8 inches. First, we need to convert 9 feet to inches by multiplying it by 12 (since there are 12 inches in 1 foot). So, 9 feet = 9 x 12 = 108 inches. Next, we can divide 108 inches by 8 (since 1 link is approximately 8 inches) to find the number of links. 108 inches ÷ 8 = 13.5 links. Therefore, there are approximately 13.5 links in 9 feet.

The are of a rectangle is 525 square centimeters. The ratio of the length to the width is 7: 3. Find the length and the width.
Answers
width 3x
length 7x
3x.7x =525
21.x^2 =21.25
x^2=5^2
x=5
length 7x=7.5 =35
width 3x=3.5=15
To solve for the rectangle's dimensions, the area 525 cm² is divided by the ratio of length to width (7:3), revealing a width of 15 cm and a length of 35 cm.
To find the length and width of a rectangle with an area of 525 square centimeters and a length-to-width ratio of 7:3, we can use proportions. Let's define the width as w centimeters. Then, since the ratio of the length to the width is 7:3, the length can be represented as (7/3)w centimeters.
The area of a rectangle is given by length imes width. Therefore, we can set up the equation (7/3)w × w = 525 to represent the area. To find w, we solve for w² = (525 × 3) / 7, which gives us w² = 225.
By taking the square root of both sides, we see that w = 15 centimeters. Now to find the length, we use the ratio: length = (7/3) × 15 = 35 centimeters.

Lines with equations y=−4x−3 and 4x+y=−1 are neither parallel nor perpendicular to the line −x+4y=20. The line y=−14x+6 is also neither parallel nor perpendicular to the given line. The line −x+4y=8 is parallel to the given line.
Explanation:To determine whether lines are parallel, perpendicular, or neither to the given line −x+4y=20, we'll need to look at their slopes. If the slopes are the same, the lines are parallel. If the product of the slopes is -1, the lines are perpendicular.
First, we should rewrite the given equation in y = mx + b format to identify the slope. The equation becomes y = 1/4x + 5. The slope for the given line is 1/4.
The first equation, y=−4x−3, has a slope of -4. This is neither equal to 1/4 nor its negative reciprocal, so the line is neither parallel nor perpendicular. The second equation, y=−14x+6, has a slope of -14. This is not equal to 1/4 or a negative reciprocal of 1/4, so this line is also neither parallel nor perpendicular. The third equation, −x+4y=8, can be rewritten as y = 1/4x + 2, which shares a slope with the given line and is therefore parallel. The last equation, 4x+y=−1, can be rewritten as y = -4x - 1, also has a slope of -4, thus it is neither parallel nor perpendicular to the given line.

A new drug has been found to be effective in treating 75% of the people afflicted by a certain disease. If the drug is administered to 400 people who have this disease, what are the mean and the standard deviation of the number of people for whom the drug can be expected to be effective? (Round your standard deviation to two decimal places.)
Answers
Answer:
The mean is 300 and the standard deviation is 8.67.
Step-by-step explanation:
It has been given that the drug has been found to be effective in treating 75% of the people afflicted by a certain disease.
Therefore, probability of success is given by p = 0.75
Now, total number of people affecting from the disease, n = 400
We know the formula for mean, which is given by
[tex]\mu=np\\\mu=400\times 0.75\\\mu=300[/tex]
And the standard deviation is
[tex]\sigma=\sqrt{np(1-p)}\\\sigma=\sqrt{400\cdot0.75(1-0.75)}\\\sigma=8.67[/tex]
Therefore, the mean is 300 and the standard deviation is 8.67.

b) price to max profit = $125
c) Suppose that a 5 dollar per drill tax is imposed. Determine the number of drills that should be produced and sold in order to maximize profit under these new circumstances. ???
Answers
Revenue x * p = 220x - x^2/30
d/dx = 220 * 15 = 3300
B.
Profit = Revenue - Cost
= 220x - x^2/30 - 72000 - 80x
d/dx = 220 - x/15 - 80 = 0
x = 15 * 140 = 2100
p = 220 - 2100/30 = 220 - 70 = $150
C.
With $5 tax the price-demand equation should be
p = 220 - x/30 + 5
Profit = 225x - x^2/30 - 72000 - 80x
d/dx = 225 - x/15 - 80 = 0
x = 15 * 145 = 2175
A refrigerator is priced at $1,250. There are two options offered to reduce the price: either a 25% discount off the price or a rebate of $300. Which is the better choice, and what is the extra amount saved?
A.The 25% discount is better; it saves $12.50.
B.The rebate is better; it saves $12.50.
C.The 25% discount is better; it saves $75.
D.The rebate is better; it saves $75.
Answers
Answer:
A.The 25% discount is better; it saves $12.50.
Step-by-step explanation:
Here, the given marked price of the refrigerator = $ 1250,
In first option,
Discount percentage = 25 %,
Thus, total discount = 25 % of the marked price
= 0.25 × 1250
= 312.5
Thus, the selling price = 1250 - 312.5 = $ 937.5,
In second option,
Discount = $ 300,
Thus, the selling price = 1250 - 300 = $ 950,
Since, 937.5 < 950
Hence, First option is better than that of second.
Also, total saving = 950 - 937.5 = $ 12.5
⇒ The 25% discount is better; it saves $12.50

An equation for this problem- The cable company charges a monthly fee of $45. Each movie rental is $1.99. You owe $68.88/ How many movies did you rent?
Answers
Answer:
12 movies
Step-by-step explanation:
If you have to pay 1.99 per movie and that is our unknown, we can express that as 1.99x, where x is the number of movies (our independent variable). If you rent 0 movies, you still have to pay the company $45. So the equation for the number of movies you rent:
y = 1.99x + 45 where y is the total cost of your cable for that month. We know the cost for a certain month was 68.88 so our equation becomes
68.88 = 1.99x = 45 and
23.88 = 1.99x so
x = 12 movies
To calculate the number of movies you rented, first subtract the monthly fee of $45 from the total amount owed of $68.88, which leaves $23.88 for movie rentals. Since each movie costs $1.99, divide $23.88 by $1.99 to get approximately 12 movies rented.
Explanation:
The subject of this question is a simple algebraic problem involving a basic equation. To find out how many movies were rented, we first need to understand what charges make up the total charge of $68.88. Given that the cable company charges a monthly fee of $45 and each movie rental costs $1.99, we know that the total charge of $68.88 includes both the monthly fee and the cost of movie rentals.
To find out how many movies were rented, we subtract the monthly fee from the total owed: $68.88 - $45 = $23.88. This is the total cost for movie rentals. Since each movie costs $1.99, we divide the total cost of rentals by the cost per movie: $23.88 / $1.99. The answer is about 12, "so you rented approximately 12 movies".

The length of a rectangle is 6 inches longer than its width. the perimeter of the rectangle is 28 inches. if x represents the width of the rectangle, which equation can be used to find its value?
Answers
I hope choice must be given so that we can select which equation can be used to find its value.
I am showing the steps for this problem.
Given that, x represents the width of the rectangle and the perimeter of the rectangle is 28 inches.
Let's assume y represent the length of the rectangle.
Formula to find the perimeter of a rectangle is,
p= 2 * length + 2 * width.
Hence, we can set up an equation as following.
2 y + 2x = 28.
Hope this is your question, if not I think you will, still be able to
find an answer of your question based on this solution.
Hope this helps you!.
Answer: The answer is 2 × (6 + x) + 2 × x = 28.
Step-by-step explanation: Given that the length of a rectangle is 6 inches longer than its width. the perimeter of the rectangle is 28 inches. if x represents the width of the rectangle, then we are to find the equation that finds the value of 'x'.
Since width of the rectangle is 'x' inches and length is 6 inches longer than the width, so length will be (6 + x) inches.
Also, perimeter is 28 inches, therefore, we have
[tex]2\times(6+x)+2\times x=28\\\\\Rightarrow 6+x+x=14\\\\\Rightarrow 2x=8\\\\\Rightarrow x=4.[/tex]
Thus, the value of x is 4 inches, hence width = 4 inches and length = 4 + 6 = 10 inches.
11 + (6-x/2) = 26
