the length of a rectangular building is 6 feet less than 3 times t he width. The perimeter is 120 feet. Find the width and the l

garri49 [273]

Call the width x. Note that the length is 3x-6. We know that double the width plus double the length is 120, so we write an equation:

$2(x)+2(3x-6)=120$
$2x+6x-12=120$
$8x-12=120$
$8x=132$
$x=16.5$
If x is 16.5, the width is 16.5, and the length is $3 \cdot 16.5 - 6 = 43.5$ .

A 180-watt iHome® is used on an average of three hours a day. Find the cost of listening to the iHome for one week at a cost of

IgorLugansk [536]

<h2>Hello!</h2>

The answer is:

The correct option is:

A. $0.49

<h2>Why?</h2>

From the statement, we know that the iHome is used on average three hours a day, and we are asked to find the cost for a week, so first, we need to calculate the total hours that the iHome is used for, and then, calculate the kilowatt-hour consumption rate.

$TotalTime_{week}=3\frac{hours}{day} *7days=21hours$

$TotalEnergyConsumption_{week}=180watt*21hours=3780watt.hour$

Now, we must remember that:

$1Kilowatt=1000watts$

So,

$3780watts=3780watts.hour*\frac{1KiloWatt}{1000watts}=3.78KiloWatt.hour$

Then, calculating the cost, we have:

$TotalCost_{week}=0.13\frac{dollar}{killowat.hour}*3.78killowat.hour=0.49(dollar)$

Hence, we have that the correct option is:

A. $0.49
