Answer:

7.9 centimeters

Step-by-step explanation:

14.8 - 2.4 = 12.4 so you now know the new circumference

12.4/pi = 3.95 which is the new radius

3.95 x 2 = 7.9 which is the new diameter

Domain: The domain is all the x-values (-2, -5, 3, -5)

Range: The range is all the y-values (6, -1, 7, 0)

Function: It's not a function because of the x-value -5 is repeating.

A regular hexagon has an apothem of 14.7 inches and a perimeter of 101.8 inches. What is the area of the hexagon?
Neporo4naja [7]

<u>Answer</u>

748.23 in²


<u>Explanation</u>

Apothem a line from the centre of a regular polygon at right angles to any of its sides. This can be said to be the height of the triangle in a polygon.

The base of the  hexagon = 101.8 ÷ 6

                                            = 19.96666..

                                            = 19.9667 inches

Area of the  hexagon = 1/2 × height × base length × 6

                                     = 1/2 × 14.7 × 19.9667 × 6

                                      = 748.23 in²

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
