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]

Why would a bank be more likely to make a loan to someone with a FICO score of 750 rather than someone with a score of 500? a) The higher the score, the greater the interest rate the lender can charge the borrower b) The closer the score to zero, the less the person owes in debt to other companies c) The higher the score, the less risk to the lender that the borrower will be past due on their payments d) None of the above
Answers
Answer:
c) The higher the score, the less risk to the lender that the borrower will be past due on their payments
Explanation:
Fair Isaac Corporation scores are used to measure the creditworthiness of a borrower. The higher the credit scores, the higher the chances of the borrower paying back what was borrowed. Credit scores are in ranges. Credit scores below 500 are rated as Poor and indicates that the borrower's chances of returning what was borrowed are very low.
Credit scores between 740-799 are rated as very good and indicate that the borrower would be prompt in the repayment of his loan.
Answer: the higher the score, the less the risk to the lender that the borrower will be past due on their payments

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.

Sung must charge 5.5% sales tax on all items sold? What is the balance on Village Plumbers’ charge account?
Answers
Answer:
$297.66
Explanation:
The total costs of the items would be
200 feet pipe : 200 x $0.40 = $80.00
150 elbow joints: 150 x $0.75 = $112.50
36 outdoor faucets: 36 x $2.49 =$ 89.64
Total cost =$282.14
add 5.5% tax
=5.5/100 x $282.14 =$15.52
Total $297.66
The balance on Village Plumbers’ charge account =$297.66

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
which causes US GDP to increase? a.japan exports more goods to US b.US government reduces government expenditure c. US sells more goods to japan d.there is a fall in consumption level in US
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.

Jim and Lisa are buying their first home together. The purchase price is $157,500.00 and they are putting a 20 percent down payment on the home. They have been approved for a 20-year loan at a 6 percent interest rate. What is the total amount of interest that they will pay during the entire loan?
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.

What is the minimum down payment they can make to reach the conforming loan limit but still retain savings
Answers
Answer:
$35,900
Explanation:
The computation of the down payment is as follows:
= Purchase price of the home - loan limit
= $546,300 - $510,400
= $35,900
Hence, the minimum down payment they can make to reach the conforming loan limit but still retain savings is $35,900
The same is to be considered by applying the above formula

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
