Answer:
Length of the rectangle = 13 ft
Step-by-step explanation:
Let l be the length and w be the width of this rectangle.
Two less than three times the width of a rectangle is equal to the length, that is
3w - 2 = l---------------------------eqn 1
The area of the rectangle is 65 square ft
l x w = 65
Substituting eqn 1
(3w - 2) x w = 65
3w² - 2w -65 = 0
Solving quadratic eqn
[tex]w=\frac{-(-2)\pm \sqrt{(-2)^2-4\times 3\times (-65)}}{2\times 3}=\frac{2\pm \sqrt{4+780}}{6}\\\\w=\frac{2\pm \sqrt{784}}{6}\\\\w=\frac{2\pm 28}{6}\\\\w=\frac{2+28}{6}\texttt{ or }w=\frac{2-28}{6}\\\\w=5\texttt{ or }w=-4[/tex]
w cannot be negative
Hence width, w = 5 ft
Substituting in eqn 1
3 x 5 - 2 = l
l = 13 ft
Length = 13 ft
Length of the rectangle = 13 ft
Solve by factoring.

A shopper purchased 8 T-shirts and 5 pairs of pants for $220. The next day he purchased 5 T-shirts and 1 pair of pants for $112. How much does each T-shirt and each pair of pants cost?
By setting up a system of linear equations based on the shopper's purchases and solving it, we found that the cost of each T-shirt is $20, and the cost of each pair of pants is $12.
Explanation:To find out how much each T-shirt and each pair of pants cost based on the shopper's purchases, we can set up a system of linear equations. Let's denote the cost of a T-shirt as T and the cost of a pair of pants as P.
The two purchases give us these equations:
8T + 5P = $220
5T + 1P = $112
Next, we use a method such as substitution or elimination to solve these simultaneous equations. If we multiply the second equation by 5, we get:
5(5T + 1P) = 5($112)
25T + 5P = $560
Now subtract the first equation from this result:
25T + 5P - (8T + 5P) = $560 - $220
17T = $340
T = $20
Now that we know the cost of a T-shirt, we can substitute T in one of the original equations to find P:
5T + P = $112
5($20) + P = $112
$100 + P = $112
P = $12
So, a T-shirt costs $20 and a pair of pants costs $12.

Which distribution has the greatest spread?
Mean Standard
Deviation
Distribution 1 22 0.2
Distribution 2 21 0.8
Distribution 3 19 1.2
Distribution 4 20 3.2
Answer:
Distribution 4, mean is 20 and standard deviation is 3.2
Step-by-step explanation:
The standard deviation tells us on average how far each of our data values is from the mean. A standard deviation that is larger than the others will mean a distribution that is more spread out than the others; 3.2 is the largest standard deviation, so Distribution 4 has the greatest spread.

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.
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.

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.
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?
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".
