If the area of the rug in this den 80 square feet and the width of the carpet is 8’,what is the perimeter of the rug?
lesya692 [45]
The area is 80 square ft and they give us the width which is 8’ so 8 times 10 gives us 80 square feet which is the area meaning 10 is the length now we add 8+8= 16 and then 10+10= 20 20+16= 36 so the answer is 36 for the question.

Rick Mendez bought stock for $5,000, using $2,500 of his own money and $2,500 borrowed from the broker. One month later, the sto
-BARSIC- [3]

Answer:

It is 6%

Explanation:

The stock that is bought by Rick Mendez: 5,000

Own money used to buy: 2,500

Borrowed money: 2,500

Interest on borrowed money : 30

Brokerage commissions: 300

The stock is sold after one month: 5,650

Now first calculate the net profit = Selling price of stock – cost price of stock – Interest on borrowing – commission

5,650-5,000-30-300=320

Now calculate the rate of return = Net profit / cost of stock

320/5,000=.06

.06 or 6%

A homeowner is installing a swimming pool. You have been asked to install a circuit to operate a 600-watt underwater light and a
insens350 [35]

Answer:

The answer is given below

Step-by-step explanation:

The loads in the circuit are continuous duty, so the circuit can only loaded to 80% of its current rating.

Calculate 80% current rating of the circuit breaker.

Icb = [ 80/100] (20 A)

     =  (O.8) (20 A )

     = 16 A

Now we assume that the value of supply voltage is 120 V

Now we will calculate current flows via under water light which will be taken as  Load 1

<em>Ii = </em>500 W/120 V

  = 4.167 A

Current via the circulating pump which will be taken as Load 2 IS 8.5 A

<em>I = </em>load1 + load 2

<em>    = 4.167 A + 8.5 A</em>

<em>   = 12.67 A</em>

The total current in the circuit obtained which is less than the circuit breaker rating current. Therefore, the power can be operated for both the loads.
