There are approximately 113 million TVs in the United States. Each uses, on average, 76 W of power and is turned on for 6.3 hour

ioda

Answer:

$76 W *\frac{1kW}{1000 W}= 0.076 kW$

$0.076 kW * 6.3 \frac{hours}{day}= 0.4788 \frac{kWh}{day}$

$113x10^6 people * \frac{0.4788 kWh}{people}= 54104400 kWh$

And finally we can convert this into money like this:

$54104400 kWh *\frac{0.089 dollars}{1 kWh}= 4815291.6$

So they spent every day approximately in total $ 4815291.6 dollars

Step-by-step explanation:

For this case we can convert the average power into Kw like this:

$76 W *\frac{1kW}{1000 W}= 0.076 kW$

Now on average we know that one person use on average this power over 6.3 hours per day so then we have the following consumption rate:

$0.076 kW * 6.3 \frac{hours}{day}= 0.4788 \frac{kWh}{day}$

And now we know the total population so then the total consumption per day would be:

$113x10^6 people * \frac{0.4788 kWh}{people}= 54104400 kWh$

And finally we can convert this into money like this:

$54104400 kWh *\frac{0.089 dollars}{1 kWh}= 4815291.6$

So they spent every day approximately in total $ 4815291.6 dollars

Suppose you need to minimize the cost of fencing in a rectangular region with a total area of 450 square feet. The material that

natta225 [31]

Answer:

The problem is stated as:

Min C = 15*(2*x +y) + 21*y

subject to x*y = 450

Step-by-step explanation:

Given that the region is rectangular, it has two opposite sides called x and two other opposite sides called y (both measured in feet). Then, the area (in square feet) is:

A = x*y = 450

One of the sides called y costs $21 per linear foot. The other 3 sides (two x and one y) costs $15 per linear foot. Then, the cost function is:

C = 15*(2*x +y) + 21*y
