Answer:

The speed of the car is 67.77 m/s and it is moving away from the observer.

Explanation:

The apparent frequency is given as

f' = f\dfrac{ [v - vo]}{ [v - vs]}

Here

o is the  observer

s is the source which is car

v is the speed of  sound  = 343 m/s

f = true frequency emitted by the car (when stationary)

f ' = 0.835 f

so

f' = f\dfrac{ [v - vo]}{ [v - vs]}\\0.835 f= f\dfrac{ [v - vo]}{ [v - vs]}\\0.835 = \dfrac{ [343 - 0]}{ [343 - vs]}\\0.835=\frac{343}{343-x}\\x=-67.77 m/s

The speed of the car is 67.77 m/s and it is moving away from the observer.

AleksandrR [38]

Explanation:

The amount that the home needs to sell can derived from the net to seller's formula given as: Net to seller = Sale Price * (100% - commission rate)

sale price =$105263.16

For the seller to receive $100000 after 5% commission the property must e sold for $105,263.16

After losing all of this distribution, one option for it might have been a form of nonstore retailing that uses machines to offer goods for sale. This is an example of automatic vending.

Right here are the styles of retailing that exist these days – save retailing: This includes different forms of retail stores like branch shops, specialty shops, supermarkets, comfort shops, catalog showrooms, drug shops, superstores, discount stores, excessive cost stores, and so forth.

The retailing concept is an idea that examines the evolution of and transformation of the retail lifestyles cycle. This concept was first introduced by using Professor McNair from Harvard College. The retailing idea indicates new retailers will generally begin with low-value and occasional-margin operations.

Retail is the sale of products and services to purchasers, in comparison to wholesaling, that is sales to business or institutional clients. A store purchases goods in massive quantities from manufacturers, without delay or via a wholesaler, after which sells in smaller quantities to purchasers for a profit.

marysya [2.9K]

Answer:

$20,226

Explanation:

expected sales = 11,400 - 12,000 - 12,600

expected sales price = $7.20 - $7.50 - $7.80

expected variable cost = $3.072 - $3.20 - $3.328

total fixed costs = $31,000

if you use an excel spreadsheet you can calculate all the different possible simulations and combine all the expected sales x 3 different price levels x 3 different variable costs and 1 fixed cost. Once you get all the 27 possible solutions, you just get the average.

I attached it because there is no room here.

Answer:

Cookie & Coffee Creations Inc.

a) Current Portion of Note Payable:

= $4,000

b) Long-term Portion of Note Payable:

= $6,000

Explanation:

Data and Calculations:

Date of Note Payable = November 1, 2017

Period = 3 years

Interest rate = 5%

Terms of payment:

Fixed principal payments = $2,000

Payment dates = May 1 and November 1

Each year's principal repayment = $4,000 ($2,000 x 2)

From November 1, 2017 to October 31, 2018 = $4,000

At October 31, 2018, Payment made = $2,000 on May 1

Remaining Note payable = $10,000 ($12,000 - $2,000)

Current Portion = $4,000 ($2,000 x 2)

Long-term Portion = $6,000

b) The current portion of $4,000 will be payable on November 1, 2018 and May 1, 2019.  The current portion represents the short-term portion of the note payable, which is the portion that will be settled within a 12-months' period.  Since Cookie & Coffee Creations Inc. had already paid $2,000 on May 1, 2018, the long-term portion will only remain $6,000 ($12,000 - $2,000 - $4,000), which is the difference between the total note payable, the portion paid on May 1, 2018, and the current portion of $4,000 that will be payable within one year.
