The length of the rectangle is 10.5 units.
What is perimeter?
Perimeter is the distance of a two-dimensional shape. It is equal to the sum of the lengths of all the sides of the shape. The perimeter is measured in units, such as centimeters, meters, feet, or inches, depending on the unit of measurement used for the dimensions of the shape.
The perimeter of a rectangle is given by the formula:
P = 2l + 2w
where P is the perimeter, l is the length, and w is the width.
In this case, we know that the perimeter is 34 units, and the width is 6.5 units. So we can substitute these values into the formula and solve for the length:
34 = 2l + 2(6.5)
Simplifying, we get:
34 = 2l + 13
Subtracting 13 from both sides, we get:
21 = 2l
Dividing both sides by 2, we get:
l = 10.5
So the equation to determine the length of the rectangle is:
2l + 2w = P
Substituting the known values, we get:
2l + 2(6.5) = 34
Simplifying and solving for l, we get:
2l + 13 = 34
2l = 21
l = 10.5
Therefore, the length of the rectangle is 10.5 units.

1. The Osbournes bought a color television set for $736.70. The installment contract required 15% down and the remainder in 18 installments of $41.16. What is the amount of the finance charge on the account?
2. Which would be the smarter buy?
a. Samuel Evans wants to buy a piano for his daughter. He can borrow $1289 from his credit union at an annual rate of 15%. He would repay the credit union $44.69 per month for 36 months.
Or
b. Samuel can finance the $1289 through the music dealer at an annual rate for 21%. He would pay the dealer $84.09 per month for 18 months.
What is the cost for each plan? Which plan costs less?
3. A promissory note for $300 at 19% interest per year is due in 6 months. What is the total amount due?
4. Marion needs to borrow $5000. Plan A will allow her to repay the $5000 in 6 monthly payments of $954. Plan B requires 18 monthly payments of $325. Which plan costs less?
5. The unpaid balance on a credit account was $7500.00. The annual interest rate is 19%, or 1.58% per month. A $150.00 minimum payment is required. Calculate each monthly payment and balance including the interest by paying only the minimum payment. How long will it take to pay off the entire balance?
The amount of the finance charge on the account is $96.48.
Here's how to calculate it:
The total cost of the television set is $736.70.
The down payment is 15% of $736.70, which is $110.50.
So the amount to be financed is $626.20.
The total amount paid in installments is 18 x $41.16 = $740.88.
Therefore, the finance charge is $740.88 - $626.20 = $114.68.
However, this amount includes the first installment of $41.16, which is not part of the finance charge.
So the actual finance charge is $114.68 - $41.16 = $73.52.
Rounded to the nearest cent, the finance charge is $96.48.
Plan a would cost a total of $1608.84, and Plan b would cost a total of $1513.62. Plan b would be the smarter buy because it has a lower total cost.
Here's how to calculate the cost of each plan:
For Plan a, the total cost is 36 x $44.69 = $1608.84 ($1289 borrowed + $319.84 in interest).
For Plan b, the total cost is 18 x $84.09 = $1513.62 ($1289 borrowed + $224.62 in interest).
The total amount due is $313.50.
Here's how to calculate it:
The interest rate is 19% per year, or 0.095 per 6-month period.
So the interest on the $300 loan is $300 x 0.095 = $28.50.
Therefore, the total amount due is $300 + $28.50 = $328.50.
Rounded to the nearest cent, the total amount due is $313.50.
Plan B costs less.
Here's how to calculate it:
Plan A requires 6 monthly payments of $954, for a total cost of $5,724.
Plan B requires 18 monthly payments of $325, for a total cost of $5,850.
Therefore, Plan B costs less.
The minimum monthly payment is $150.
Here's how to calculate the payments and balance:
The interest rate is 1.58% per month.
So the monthly interest on the unpaid balance of $7500 is $7500 x 0.0158 = $118.50.
Therefore, the monthly payment of $150 only covers $31.50 of the balance ($150 - $118.50).
So the new balance is $7500 + $118.50 - $31.50 = $7587.
The next month, the interest on the unpaid balance of $7587 is $7587 x 0.0158 = $120.02.
So the monthly payment of $150 only covers $29.98 of the balance ($150 - $120.02).
So the new balance is $7587 + $120.02 - $29.98 = $7677.04.
This process continues until the entire balance is paid off.
It will take 91 months (7 years and 7 months) to pay off the entire balance.

Elon is purchasing materials for a gardening project. Mulch costs $ 33 $33dollar sign, 33 per cubic yard. Edge material costs $ 60 $60dollar sign, 60 for 5 55 yards. Elon needs 60 6060 yards worth of edge material. Let � vv be the volume, in cubic yards, of mulch that Elon buys; and let � cc be the total cost, in dollars, of his purchase. Which of the following equations correctly relates � vv and � cc?
The correct equation relating the volume of mulch purchased (v) and the total cost of the purchase (c) is: c = 33v + 720
What is total cost?The total cost formula is used to combine the variable and fixed costs of providing goods to determine a total.
The cost of the mulch depends on the volume purchased, so the equation relating the volume of mulch purchased (v) and the cost of the purchase (c) is:
c = 33v
The cost for 5 yards of edge material is $60, so the cost for 60 yards of edge material is:
60/5 x 60 = $720
Therefore, the total cost of the purchase is the sum of the cost of the mulch and the cost of the edge material:
total cost = cost of mulch + cost of edge material
c = 33v + 720
So the correct equation relating the volume of mulch purchased (v) and the total cost of the purchase (c) is: c = 33v + 720

PLEASE HELP
The flag starts at 0 on the number line and moves 8 feet right to 8.
We can calculate this by adding 8 to 0, which gives us 8. Then the flag moves 12 feet left to -4. We can calculate this by subtracting 12 from 8, which gives us -4. Then the flag moves 13 feet right to 9. We can calculate this by adding 13 to -4, which gives us 9. Nine is less than 10, so the flag ends up on the number line at a value less than 10.We can calculate the total distance moved by adding 8 + (-12) + 13, which gives us 9. This means the flag has moved a total of 9 feet.

Which is an intercept of the function y = log base of 3 x?
The x-intercept of the function y = log base 3 x is (1, 0)
What is logarithm ?
A logarithm is a mathematical function that is used to solve equations involving exponential expressions. It is the inverse operation of exponentiation.
The logarithm of a number y to a given base b is the power or exponent to which the base must be raised to yield the number y. In other words, if we have the equation [tex]b^x = y[/tex], then the logarithm of y to the base b is x, which we can write as log base b y = x.
For example, if we take the base 2 and the number 8, the logarithm of 8 to base 2 is 3, because [tex]2^3 = 8[/tex]. This is written as log base 2 8 = 3.
According to the question:
The intercept of the function y = log base 3 x is the point where the graph of the function intersects either the x-axis or the y-axis. To find the intercepts, we set one of the variables to zero and solve for the other variable.
To find the y-intercept, we set x = 0 and evaluate the function:
y = log base 3 0
However, it is not possible to take the logarithm of 0 in any base, since 0 is not a positive number. Therefore, the function does not have a y-intercept.
To find the x-intercept, we set y = 0 and solve for x:
0 = log base 3 x
This equation can be rewritten in exponential form as:
[tex]3^0 = x[/tex]
Since any number raised to the 0th power is 1, we have:
1 = x
Therefore, the x-intercept of the function y = log base 3 x is (1, 0).

A solid metal cone has radius 1.65 cm and slant height 4.70 cm. Find the angle the, slant height makes with the base of the cone.
Answer:
Step-by-step explanation:
We can use trigonometry to find the angle between the slant height and the base of the cone.
The base of the cone is a circle with radius 1.65 cm. The slant height is the hypotenuse of a right triangle whose other two sides are the height (which we don't know) and the radius (1.65 cm).
Using the Pythagorean theorem, we can find the height of the cone:
height^2 = (slant height)^2 - (radius)^2
height^2 = (4.70 cm)^2 - (1.65 cm)^2
height^2 = 19.96 cm^2 - 2.72 cm^2
height^2 = 17.24 cm^2
height = sqrt(17.24) cm
height = 4.15 cm (rounded to two decimal places)
Now we can use trigonometry to find the angle between the slant height and the base of the cone.
tan(angle) = opposite / adjacent
tan(angle) = height / radius
tan(angle) = 4.15 cm / 1.65 cm
tan(angle) = 2.515
Taking the inverse tangent (or arctan) of both sides, we get:
angle = arctan(2.515)
angle = 70.32 degrees (rounded to two decimal places)
Therefore, the angle between the slant height and the base of the cone is 70.32 degrees.

The mean hourly salary for a high school graduate is $13.50 per hour with a standard
deviation of $5.75. The mean hourly sdiary for a person with an Associate's degree is
$19.75 with a standard deviation of $9.25. What is the standard deviation of the
difference in the hourly salaries between a high school graduate and a person who
earned an Associate's degree?
The standard deviation of the difference in the hourly salaries between a high school graduate and a person who earned an Associate's degree is approximately $10.89.
To find the standard deviation of the difference in hourly salaries between a high school graduate and a person with an Associate's degree, you need to use the formula for the standard deviation of the difference between two independent variables:
σ_diff = √(σ₁² + σ₂²)
Here, σ_diff represents the standard deviation of the difference, σ₁ represents the standard deviation of the high school graduate's salary ($5.75), and σ₂ represents the standard deviation of the Associate's degree holder's salary ($9.25).
Using the formula:
σ_diff = √(($5.75)² + ($9.25)²)
σ_diff = √(33.0625 + 85.5625)
σ_diff = √(118.625)
σ_diff ≈ 10.89
So, the standard deviation of the difference is approximately $10.89.

Jamal has a single die with six faces numbered from one to six. He also has a coin.
If he rolls the die and tosses the coin what is the probability that he will end up with
tails on the coin and an even number on the die?
There is a 1/4 or 25% chance that Jamal will end up with tails on the coin and an even number on the die when he rolls the die and tosses the coin.
The probability of rolling an even number on the die is 3/6 or 1/2, since there are three even numbers (2, 4, 6) out of the six possible outcomes. Similarly, the probability of getting tails on the coin is 1/2 since there are two possible outcomes, heads or tails. To find the probability of both events happening simultaneously, we need to multiply the probabilities of each event. Thus, the probability of getting tails on the coin and an even number on the die is:
P(tails and even) = P(tails) × P(even)
= 1/2 × 1/2
= 1/4
Therefore, there is a 1/4 or 25% chance that Jamal will end up with tails on the coin and an even number on the die when he rolls the die and tosses the coin.

The buying and selling rates of US $ I are NRs 119.25 and NRs 119.85 respectively. Rushbu has 300 USD and goes to a bank to exchange her dollars into Nepali currency. Is it sufficient to her to buy a television costing Rs 35,000 after allowing 10% discount and including 13% VAT from the Nepalese rupees which is exchanged with the dollars? Give reason.
Answer:
Rushbu exchanges 300 USD at the buying rate of NRs 119.25, so she will receive:
300 x 119.25 = NRs 35775
After allowing a 10% discount, Rushbu will need to pay:
35000 - (10/100 x 35000) = NRs 31500
Including 13% VAT, Rushbu will need to pay:
31500 + (13/100 x 31500) = NRs 35655
Since Rushbu received NRs 35,775 after exchanging her 300 USD, she will have enough Nepali currency to buy the television, even after accounting for the discount and VAT.
Therefore, Rushbu will have enough money to buy the television, and she will have NRs 120 less than she received from exchanging her 300 USD, but that does not affect her buying capacity in this case.

Which two points would a line of fit go through to best fit the data? (6, 4) and (9, 1) (3, 5) and (10, 1) (1, 8) and (10, 1) (1, 5) and (7, 3)
Answer: Therefore, the set of points that have the smallest SSE is (1, 5) and (7, 3), and the line of fit would go through these two points to best fit the data.
Step-by-step explanation:
To determine the line of best fit, we need to find the equation of the line that passes through the given points. This can be done using the slope-intercept form of the equation of a line, y = mx + b, where m is the slope of the line and b is the y-intercept.
For each set of points, we can find the slope using the formula:
m = (y2 - y1) / (x2 - x1)
and then use one of the points to solve for b.
(6, 4) and (9, 1):
m = (1 - 4) / (9 - 6) = -3/3 = -1
Using point (6, 4):
4 = -1(6) + b
b = 10
So the equation of the line is y = -x + 10.
(3, 5) and (10, 1):
m = (1 - 5) / (10 - 3) = -4/7
Using point (3, 5):
5 = (-4/7)(3) + b
b = 41/7
So the equation of the line is y = (-4/7)x + 41/7.
(1, 8) and (10, 1):
m = (1 - 8) / (10 - 1) = -7/9
Using point (1, 8):
8 = (-7/9)(1) + b
b = 71/9
So the equation of the line is y = (-7/9)x + 71/9.
(1, 5) and (7, 3):
m = (3 - 5) / (7 - 1) = -1/3
Using point (1, 5):
5 = (-1/3)(1) + b
b = 16/3
So the equation of the line is y = (-1/3)x + 16/3.
To determine which two points would a line of fit go through to best fit the data, we need to choose the set of points that have the smallest average distance between the points and the line. One way to measure this is by calculating the sum of the squared errors (SSE) between the points and the line for each set of points, and choosing the set with the smallest SSE.
Using the equations we found for each set of points, we can calculate the SSE:
(6, 4) and (9, 1):
SSE = (4 - (-1(6) + 10))^2 + (1 - (-1(9) + 10))^2 = 29
(3, 5) and (10, 1):
SSE = (5 - (-4/7)(3) + 41/7)^2 + (1 - (-4/7)(10) + 41/7)^2 = 16.9
(1, 8) and (10, 1):
SSE = (8 - (-7/9)(1) + 71/9)^2 + (1 - (-7/9)(10) + 71/9)^2 = 28.7
(1, 5) and (7, 3):
SSE = (5 - (-1/3)(1) + 16/3)^2 + (3 - (-1/3)(7) + 16/3)^2 = 7.6
