Answer:
85 hours
Step-by-step explanation:
Multiply 13 by 6 to know how much she worked in those 6 days and then add 7 more hours to that and you should get 85 hours in total.
Answer: 85 hours
Step-by-step explanation:
Donna worked for 13 hours every day for 6 days:
This means that she worked 13 hours each day so what we have to do is this:
13·6 = 78 <------- That is the amount of hours she worked for 6 days
Now we have to figure the last day:
Donna worked 7 hours.
This part is simple, all we have to do is add 78 from our previous equation and add it to 7 hours which gives us a total of 85 hours!

Belle Corp. has a selling price of $50 per unit, variable costs of $40 per unit, and fixed costs of $100,000. What sales revenue is needed to break-even?
The sales revenue needed to break even for Belle Corp. is $500,000. This revenue will cover the fixed costs of $100,000 and the variable costs of $40 per unit, leaving a contribution margin of $10 per unit towards the break-even point.
To calculate the sales revenue needed to break even, we need to consider the fixed costs and the contribution margin per unit. The contribution margin per unit is the selling price per unit minus the variable cost per unit.
In this case, the selling price per unit is $50, and the variable cost per unit is $40. Therefore, the contribution margin per unit is $50 - $40 = $10.
To break even, the total contribution margin must cover the fixed costs of $100,000. The number of units needed to cover the fixed costs can be calculated by dividing the fixed costs by the contribution margin per unit:
Break-even point (in units) = Fixed costs / Contribution margin per unit
= $100,000 / $10
= 10,000 units
Finally, to calculate the sales revenue needed to break even, we multiply the break-even point (in units) by the selling price per unit:
Sales revenue needed to break even = Break-even point (in units) * Selling price per unit
= 10,000 units * $50
= $500,000
Therefore, the sales revenue needed to break even is $500,000.

(Round intermediate calculations to at least 4 decimal places and final answer to 3 decimal places.) I
Answer:
a. 1.00 minute (rounded to 2 decimal places)
b. 0.7568 (rounded to 4 decimal places)
c. 0.2432 (rounded to 4 decimal places)
Step-by-step Explanation:-
a. To calculate the expected arrival time, we multiply the total time range (3.7 minutes) by the probability of the elevator arriving at any given time within that range. Since the arrival time is equally likely at any time, the probability is uniformly distributed. Thus, the expected arrival time is:
Expected arrival time = (3.7 minutes) * (1/3.7) = 1.00 minute (rounded to 2 decimal places)
b. To find the probability that the elevator arrives in less than 2.8 minutes, we divide the desired time range by the total time range:
Probability = (2.8 minutes) / (3.7 minutes) = 0.7568 (rounded to 4 decimal places)
c. To find the probability that the wait for an elevator is more than 2.8 minutes, we subtract the probability from 1 since it is the complement event:
Probability = 1 - 0.7568 = 0.2432 (rounded to 4 decimal places)
Therefore, the probability that the wait for an elevator is more than 2.8 minutes is 0.243 (rounded to 3 decimal places).

Riya purchased a machine for Rs36000 and spent Rs2400 on its repair. She then sold it for Rs42000. Find the gain or loss percent
Step-by-step explanation:
Cost Price= ₹36,000
Repair Price=₹2,400
Actual Cost Price= CP + Repair Price
= ₹36,000 + ₹2,400
= ₹38400
Selling Price = ₹42000
Profit = SP - CP
= ₹42000 - ₹38400
= ₹3600
Profit% = Profit/CP × 100
= ₹3600/₹38400 × 100
= 9.375%
Answer:
gain%=9.37%(approximately)
Step-by-step explanation:
C.P.= 36000+2400
C.P.=Rs38400
S.P.=Rs42000
gain=S.P.-C.P.
gain=42000-38400
gain=Rs3600
gain%=(gain/C.P.)*100
gain%=(3600/38400)*100
gain%=9.37%(approximately)

Solve the following cash flow diagram (determine both the factors and the NPV), given: V1=$2,000.0, V2=$3,679.1,D=$305.4 at year 5, A=$287.5, and g=2.7% per year Enter "1" below and submit your full work in the dropbox submission. Full marks will only be provided for a complete solution that has: all the factors shown in the solution ( X,i,N) format, as well a correct NPV. Use an i of 6%
To solve the cash flow diagram and determine the factors and NPV, we have the following information:
V1 = $2,000.0 (Initial cash inflow)
V2 = $3,679.1 (Cash inflow at year 5)
D = $305.4 (Cash outflow at year 5)
A = $287.5 (Annual cash inflow)
g = 2.7% per year (Growth rate)
i = 6% (Discount rate)
Let's calculate the factors for each cash flow using the X, i, and N format:
Factor for V1: X = V1
i = 6%
N = 0 (Year 0)
FV = V1
Factor for V2: X = V2
i = 6%
N = 5 (Year 5)
FV = V2
Factor for D: X = -D
i = 6%
N = 5 (Year 5)
FV = -D
Factor for A: X = A
i = 6%
N = 1, 2, 3, 4 (Years 1 to 4)
FV = A * (1 + g)^N
Now, let's calculate the future value (FV) for the annual cash inflow using the growth rate:
FV = A * (1 + g)^N
FV = $287.5 * (1 + 2.7%)^1 + $287.5 * (1 + 2.7%)^2 + $287.5 * (1 + 2.7%)^3 + $287.5 * (1 + 2.7%)^4
Once we have the factors and the FV for each cash flow, we can calculate the Net Present Value (NPV) using the formula:
NPV = (Factor for V1 * FV for V1) + (Factor for V2 * FV for V2) + (Factor for D * FV for D) + (Factor for A * FV for A)
By substituting the respective factors and FV values into the NPV formula, we can calculate the NPV of the cash flow diagram.

None of these are true e. It is not possible to determine this from the information given
Based on the given information, the amount of capital this year (K1) could be something less than 25 (option c).
To determine the amount of capital this year based on the given information, we can use the investment and depreciation rates.
Let's denote the amount of capital this year as K1.
According to the information provided:
People invest 55% of income, but we don't have any information about income. Therefore, we cannot determine the exact investment amount.
10% of capital depreciates. Based on this, the capital at the beginning of this year (K1) can be calculated as follows:
K1 = K - 0.1K
= 0.9K
Since we know that the capital last year was equal to 25, we substitute K = 25 into the equation above:
K1 = 0.9 * 25
= 22.5
Therefore, based on the given information, the amount of capital this year (K1) could be something less than 25 (option c).

A rectangluar prism has volume of 2,610 cubic inches, length 3 inches, and width 29 inches . Find its height, in inches
Step-by-step explanation:
To find the height of the rectangular prism, you will need to use the formula for the volume of a rectangular prism, which is:
Volume = Length × Width × Height
In this problem, you have:
Volume = 2,610 cubic inches
Length = 3 inches
Width = 29 inches
You'll need to solve for Height. Using the formula:
2,610 = 3 × 29 × Height
First, multiply the length and width together:
2,610 = 87 × Height
Next, divide both sides by 87 to isolate Height:
Height = 2,610 / 87
Height = 30 inches
So, the height of the rectangular prism is 30 inches.
Answer:
30 inches.
Step-by-step explanation:
Given:
Volume=2610 cubic inches,
length=3 inches
width=29inches
Volume of a rectangular prism is given by.
Volume = length * width * height
We know the volume, length and width. So, we can find the height as follows:
Substituting value
2610=3*29*height
2610=87*height
height=2610/87
height=20 inches
Therefore, the height of the rectangular prism is 30 inches.

The weekly sales data for ten-grain bread at Whole Foods Market is provided for eight weeks. To forecast the demand for week 6 using a 4-week moving average (MA), we will calculate the average sales of the previous four weeks and use that as the forecast.
A 4-week moving average is a forecasting technique that involves taking the average of a specific number of previous data points to predict future values. In this case, we want to forecast the demand for week 6 using the sales data from weeks 3, 4, 5, and 6.
To calculate the 4-week MA forecast for week 6, we add the sales from weeks 3, 4, 5, and 6 and divide the sum by 4:
(420 + 382 + 410 + 432) / 4 = 411
Therefore, the forecasted demand for week 6 using the 4-week MA is 411. This means that, based on the average sales of the previous four weeks, it is estimated that Whole Foods Market will sell approximately 411 units of ten-grain bread in week 6. It's important to note that moving averages smooth out fluctuations in the data, providing a trend estimate rather than capturing short-term variations.

The following statements are true generalizations. Imagine an exceptional case for each(that is, a situation in which the rule would not apply). 1. You should return what your borrow
1. The exceptional case where the rule "You should return what you borrow" would not apply is when the borrowed item is a consumable or disposable product.
In general, when you borrow something, it is expected that you will return it to the owner once you are done using it. This principle applies to various scenarios, such as borrowing books, tools, or household items. However, there are situations where returning what you borrow may not be applicable or practical.
For instance, consider borrowing a consumable item like a pack of disposable plates or a bottle of shampoo. These items are designed for one-time use and are meant to be consumed or disposed of. In such cases, returning what you borrow wouldn't make sense because the borrowed items are not intended for reuse. Instead, it is understood that the borrower will consume or utilize the entire item and will not be expected to return it.
Similarly, if you borrow something that is meant to be temporary or perishable, such as food items or fresh flowers, returning them would not be feasible or appropriate. These items have a limited lifespan and are not intended for long-term ownership or reuse.
It's important to note that the general rule of returning what you borrow primarily applies to items that are intended for multiple uses or have a longer lifespan. Exceptions arise when dealing with consumable or perishable goods, where the expectation of returning the borrowed item does not hold due to their nature of one-time use or limited lifespan.
