The outer edge of a circular running track is 330m long. If it is widened by 7m all around, find the cost of widening it at 8 per square metre.
Answers
Answer:
Here given that perimeter of circular running track =330m
Let radius=r
As we know that in a circle
[tex]{\boxed{\sf Perimeter=2\pi r}}[/tex]
Substitute the values[tex]\qquad \quad{:}\longmapsto\tt 2\times\dfrac {22}{7}×r=330 [/tex]
[tex]\qquad \quad{:}\longmapsto\tt \dfrac {44}{7}r=330 [/tex]
[tex]\qquad \quad{:}\longmapsto\tt r=\dfrac {330×7 }{44}[/tex]
[tex]\qquad \quad{:}\longmapsto\tt r=\dfrac{2310}{44}[/tex]
[tex]\qquad \quad{:}\longmapsto\tt r=52.5 [/tex]
[tex]\therefore\sf r=53m (Approx)[/tex]
Again
[tex]{\boxed{\sf Area=\pi r^2 }}[/tex]
Substitute the values[tex]\qquad \quad{:}\longmapsto\tt Area=\dfrac{22}{7}×(53)^2 [/tex]
[tex]\qquad \quad{:}\longmapsto\tt Area=8828.2m^2 [/tex]
[tex]\therefore\sf Area=8828m^2 (Approx)[/tex]
Nowthe radius is increased by 7m
Hence
New radius=(x+7)m=53+7=60m
New Area=
[tex]\qquad \quad{:}\longmapsto\tt \pi. r^2 [/tex]
[tex]\qquad \quad{:}\longmapsto\tt \dfrac {22}{7}(60)^2 [/tex]
[tex]\qquad \quad{:}\longmapsto\tt \dfrac {22}{7}×3600 [/tex]
[tex]\qquad \quad{:}\longmapsto\tt 11314.28m^2 [/tex]
[tex]\therefore\sf AREA=11314m^2 (Approx).[/tex]
nowArea of widened Area=New area-Old Area
[tex]\qquad \quad{:}\longmapsto\tt 11314-8828 [/tex]
[tex]\qquad \quad{:}\longmapsto\tt 2486m^2 [/tex]
Cost of widening per square=8Total cost=
[tex]\qquad \quad{:}\longmapsto\tt 2486×8 [/tex]
[tex]\qquad \quad{:}\longmapsto\tt 19888[/tex]
[tex]\therefore\sf Total\:cost\:is\: 19888.[/tex]

Answers
Answer:
the supply of labor faced by an individual firm is perfectly elastic.
Explanation:
In the case of the pure or perfectly competitive market when the wage rate is calculated instead by an individual firm so the each and every firm is wage taker this implies that the real equilibrium wage would be set in the market and the labor supply that faced by an individual firm would be perfectly elastic at the market rate

Multiple choice question. sell more of one input when the price of another input falls and less of that particular input when the price of the other input rises purchase more of one input when the price of another input falls and less of that particular input when the price of the other input rises purchase less of one input when the price of another input falls and less of that particular input when the price of the other input rises purchase more of one input when the price of another input rises and less of that particular input when the price of the other input rises
Answers
Answer: Purchase more of one input when the price of another input falls and less of that particular input when the price of the other input rises
Explanation:
The Output effect is meant to explain what happens when the price of an input changes. If an input price increases for instance, production costs will rise and the company will have to buy less of other inputs to keep costs stable.
Conversely, if the price of other inputs fall, the company will see production costs fall which will enable them to purchase more of inputs which didn't change in price.

Answers
Answer:
5% higher in year 1 than in year 2.
Explanation:
As we know that the GDP deflator in year 1 or in base year it should always be 100
Also the GDP deflator in year 2 is 95
Now as we can see that the GDP for year 1 is more than GDP for year 2 by 5%
Therefore in year 1, it is 5% higher than in year 2
So, the last option is correct
hence, the same is to be considered
On January 1, 2019, Wasson Company purchased a delivery vehicle costing $45,200. The vehicle has an estimated 7-year life and a $3,900 residual value. What is the vehicle's book value as of December 31, 2020, assuming Wasson uses the straight-line depreciation method
Answers
Answer: $33,400
Explanation:
The annual depreciation using the straight-line method is;
= (Cost - Residual value) / Useful life
= (45,200 - 3,900) / 7
= $5,900
On December 31, 2020, the vehicle would have depreciated by 2 years so the book value would be;
= Cost - Accumulated depreciation
= 45,200 - (5,900 + 5,900)
= $33,400

Russell United has 28,500 shares of stock outstanding and has two open seats on its board of directors. Each share of common stock is granted one vote. How many additional votes are required to guarantee a seat on the board if the company were to use straight voting rather than cumulative voting
Answers
Answer:
4,750
Explanation:
Calculation for How many additional votes are required to guarantee a seat on the board
First step is to Calculate for STRAIGHT VOTING
Using this formula
Additional Votes= ((Shares of stock outstanding/2)+1)
Let plug in the formula
Additional Votes=((28,500/2)+1)
Additional Votes=14,251
Second step is to calculate for CUMULATIVE VOTING
Using this formula
Additional Votes= ((Shares of stock outstanding/(Number of seats +1))+1)
Let plug in the formula
Additional Votes=((28,500/(2 +1))+1)
Additional Votes=9,501
Last step is to calculate How many additional votes are required
Using this formula
Additional votes =STRAIGHT VOTING additional vote-CUMULATIVE VOTING additional Votes
Let plug in the formula
Additional votes = 14,251-9,501
Additional votes = 4,750
Therefore How many additional votes are required to guarantee a seat on the board if the company were to use straight voting rather than cumulative voting is 4,750

Answers
The US sells more goods to japan which causes US GDP to increase. The correct option is C.
Why was the US occupation of Japan successful?Japan's land reform was a major success of the US-led occupation. Agricultural land became so cheap as a result of this reform that all tenant farmers who worked for rent were able to buy their own lands by becoming landlords.
Not only did the US absorb Japanese exports and tolerate Japanese protectionism, but it also subsidized the Japanese economy and converted technology to Japanese firms. When a company sells goods, it sells them to a foreign market, which includes consumers, businesses, and governments in other countries. These exports bring money into the country, increasing the GDP of the exporting nation.
Thus, the ideal selection is option C.

A. $84,724.16
B. $86, 518.40
C. $88,724.16
D. $90,518.40
Answers
Answer: D. $90,518.40
Explanation:
They are putting a 20% down payment on the home which means they are paying 80%;
= 80% * 157,500
= $126,000
First find the monthly payments;
Present value = Payment * ((1 - (1 + r)^-n) / r)
n= 20 * 12 = 240 months
r = 6/12 = 0.5%
126,000 = Payment * (( 1 - ( 1 + 0.5%)⁻²⁴⁰) / 0.5%)
126,000 = Payment * 139.58077168292915831291691663652
Payment = 126,000/139.58077168292915831291691663652
Payment = $902.70313
They'll pay that for 240 months;
= 902.70313 * 240
= $216,648.7512
Interest = 216,648.7512 - 126,000
= $90,648.7512
= $90,648.75

The graph represents price and output quantities under a monopoly. What price will the monopolist firm set? A. $5 B. $10 C. $15 D. $20
Answers
The correct answer is C.
A monopoly is a market structure where a single firm serves the whole demand of a specific good or service. It does not face competitors, therefore, such firm has absolute market power to decide the price charged for its products.
So, the monopoly is able to charge a higher price than in a perfect competition scenario where the price would be set at the intersection betweeen the demand function and the marginal cost function.
Instead, the quantity sold in the monopoly (q*) is determined by the intersection of the marginal revenue and marginal cost curves, and the monopoly price is computed by substituting q* in the expression of the demand function (because the demand function relates price and quantity).
The result is 15$ as the picture shows.
