A bus company is replacing all the old seats in its buses with new ones. The company owns 13 buses and each bus has 28 seats. It costs $89.40 to purchase
each new seat, as well as an additional $31.70 to install each new seat. What is the total cost the company will pay?
Answer:
$44.236.20
Step-by-step explanation:
First, we need to calculate the cost of purchasing new seats for all the buses. The company has 13 buses and each bus has 28 seats, so the total number of seats to be replaced is 13 * 28 = 364 seats. The cost of purchasing each seat is $89.40, so the total cost of purchasing new seats for all the buses is 364 * $89.40 = $32,610.40.
Next, we need to calculate the cost of installing new seats for all the buses. The cost of installing each seat is $31.70, so the total cost of installing new seats for all the buses is 364 * $31.70 = $11,625.80.
Finally, we need to add the cost of purchasing and installing new seats to get the total cost the company will pay. The total cost of purchasing new seats is $32,610.40 and the total cost of installing new seats is $11,625.80, so the total cost the company will pay is $32,610.40 + $11,625.80 = $44,236.20.
Tanya decided to lease a car.
the lease includes a money factor of 0.00324.
What interest rate is shawna being charged in her lease? ( round to the nearest hundredth).
A. 0.78%
B. 7.78%
C. 1.35%
D. 13.5%
A correct answer is option (B) 7.78%. so, the interest rate is 7.78% being charged in her lease.
What is the interest rate?
Interest rate is the amount charged over and above the principal amount by the lender from the borrower. In terms of the receiver, a person who deposits money to any bank or financial institution also earns additional income considering the time value of money, termed as interest received by the depositor.
The interest rate in a lease can be calculated using the money factor, which is essentially a type of interest rate used in auto leasing.
To calculate the interest rate from the money factor, multiply the money factor by 2400.
In this case, the money factor is 0.00324, so the interest rate would be:
0.00324 * 2400 = 7.776%
Therefore, the correct answer is option (B) 7.78%. so, the interest rate is 7.78% being charged in her lease.

A correct answer is option (B) 7.78%. so, the interest rate is 7.78% being charged in her lease.
Which interest rate is it?The amount that the lender charges the borrower over and beyond the principal amount is referred to as the interest rate. A person who deposits money in a bank or other financial institution also earns additional income in terms of the recipient, known as interest, taking into account the time value of money.
The money factor, which is essentially a sort of interest rate utilized in auto leasing, can be used to compute the interest rate in a lease.
By multiplying it by 2400, you can determine the interest rate from the money element.
Given that the money component in this situation is 0.00324, the interest rate would be:
The result of three consecutive conversions from an interest rate to a money factor is 2400 (1/2 × 1/12 × 1/100). 6/2400 = 0.0025 money factor, which can be multiplied by the entire amount borrowed to see how much the monthly interest would be roughly.
(1/2 × 1/12 × 1/100). 6/2400 = 0.0025
0.00324 × 2400 = 7.776%
Therefore, the correct answer is option (B) 7.78%. so, the interest rate is 7.78% being charged in her lease.

for a sample of categorical data, the____for a given category is the number of sample items in that category divided by the sample size.
The relative frequency or proportion of a given category is the number of sample items in that category divided by the total sample size.
The relative frequency or proportion of a given category is a measure of how often that category appears in a sample of categorical data. It is calculated by dividing the number of sample items in that category by the total sample size. For example, if a sample contains 10 items and three of them are in category A, then the relative frequency for category A is 3/10 or 0.3. This indicates that 30% of the sample items are in category A. Relative frequencies are used to compare categories within a sample, as well as to compare samples of different sizes. This allows us to draw conclusions about the frequency of occurrence of different categories within a population.

If a translation is applied to square ABCD, the y-coordinate of B' = y_coordinate of B - 8 = -8.
What is the translation?
The translation is a term used in geometry to describe a function that moves an object a certain distance. The object is not altered in any other way. It is not rotated, reflected or re-sized. In a translation, every point of the object must be moved in the same direction and for the same distance.
When a translation of T-3, -8 is applied to square ABCD, it means that each point in the square is moved 3 units to the left and 8 units down.
The y-coordinate of B is found by moving 8 units down from the original y-coordinate of B.

An included angle is found between two sides that are under consideration.
In the image, the triangles are congruent to each other by the Side-Angle-Side Congruence Theorem (SAS).

Which relationship between x and y in the equation shows a proportional relationship?
1. y=5(x+3)
2. y = 5x + 3
3. y=x−2
4. y = 3x
Answer:
4. y = 3x
Step-by-step explanation:
A proportional relationship is one in which the ratio of two variables is always constant. This is also known as direct proportion.
Out of the given options, the equation that shows a proportional relationship is:
4. y = 3x
In this equation, the ratio of y to x (y/x) is always 3, so the relationship between y and x is proportional. As x increases, y also increases at a constant rate, and as x decreases, y decreases at a constant rate. This type of relationship is often represented by the equation y = kx, where k is the constant of proportionality.
Find n if (n + 1)! = 16n! + 16(n-1)!
Step-by-step explanation:
(n+1)! = (n+1)n(n-1)(n-2)...×3×2
16n! = 16n(n-1)(n-2)...×3×2
16(n-1)! = 16(n-1)(n-2)...×3×2
we can now divide both sides by (n-1)! and get
(n+1)n = 16n + 16
n² + n = 16n + 16
n² - 15n - 16 = 0
1×n² - 15n - 16 = 0
we try to bring this into a form
(n + a)(n - b)
one factor has to contain "-", because we have "-16".
and because -15 = 1 - 16, we see that
a = 1
b = 16
n² - 15n - 16 = (n + 1)(n - 16)
and that is 0, when at least one of the factors is 0, because 0×... = 0.
so, the solutions are
n = -1
n = 16
n = -1 does not make any sense for n!
so, n = 16 is the solution.

A 14-inch-wide conveyor unloads 4000 bushels of wheat per hour. At this speed, how many bushels per hour will an 21-inch-wide conveyor unload?
An 21-inch-wide conveyor would unload
Answer:
6000 bushels per hour.
Step-by-step explanation:
Let's assume that the rate at which the conveyor unloads wheat is proportional to its width.
If a 14-inch conveyor unloads 4000 bushels per hour, we can write this as:
Rate = 4000 bushels/hour * (Width of conveyor) / 14 inches
Now, if we want to find the rate at which an 21-inch conveyor would unload wheat, we can simply plug in the width into the equation:
Rate = 4000 bushels/hour * (21 inches) / 14 inches
Rate = 6000 bushels/hour
Therefore, an 21-inch-wide conveyor would unload 6000 bushels per hour.

by trigonometry the magnitude of the force P so that the resultant force exerted on the stake is vertical. The magnitude of the force is 196.6 N.
What is resultant force?When a force system acts on an item, the difference between the forces is referred to as the Resultant force. When an item is under the influence of two or more forces, the combined force may be calculated by adding up the separate forces. The forces in all directions will be the same for all the forces if they are all acting in the same direction. The SI unit for resultant force is the Newton.
Given that,
α = 30°
Using the triangle rule, and the law of sines:
120 N / Sin 30° = P / Sin 25°
or, P = (Sin 25° / Sin 30°) × 120
or, P = 101.428 N
or, P = 101.4 N
and also, θ = 180 - 25 - 30
θ = 125°
the value of resultant is:
