A certain region currently has wind farms capable of generating a total of 2200 megawatts (2.2 gigawatts) of power. Assuming win

sveta [45]

Answer:

The correct answer is A. 4,818'000,000 kilowatt-hours per year and B. 481,800 households.

Step-by-step explanation:

1. Let's review the information provided to us for solving the questions:

Power capacity of the wind farms = 2,200 Megawatts or 2.2 Gigawatts

2. Let's resolve the questions A and B:

Part A

Assuming wind farms typically generate 25% of their capacity, how much energy, in kilowatt-hours, can the region's wind farms generate in one year?

2,200 * 0.25 = 550 Megawatts

550 Megawatts = 550 * 1,000 Kilowatts = 550,000 Kilowatts

Now we calculate the amount of Kilowatts per hour, per day and per year:

550,000 Kw generated by the farms means that are capable of produce 550,000 kw per hour of energy

550,000 * 24 = 13'200,000 kilowatt-hours per day

13'200,000 * 365 = 4,818'000,000 kilowatt-hours per year

Part B

Given that the average household in the region uses about 10,000 kilowatt-hours of energy each year, how many households can be powered by these wind farms?

For calculating the amount of households we divide the total amount of energy the wind farms can generate (4,818'000,000 kilowatt-hours) and we divide it by the average household consumption (10,000 kilowatt-hours)

Amount of households = 4,818'000,000/10,000 = 481,800

You pick one card from a standard deck of 52 cards. What is the probability that the card will be a two?

Natali [406]

Answer:

4 out of 52 or simplified 2 out of 26

Step-by-step explanation:

There are 4 suites of cards, spades, hearts, clubs, diamonds and there is one card for two in each suite, so we therefore know that the probability of picking a two out of a 52 card deck will be four out of 52 or the simplified answer would be 2 out of 26. Hope this helps, have a great day!

Find the equation of the line with Slope = 6 and passing through (5,38). Write your equation in the form y =mx+b

laiz [17]

Hello.

We have:

A point that the line passes through
The slope of the line

Plug the values into the Point-Slope Formula:

$\mathrm{y-y_1=m(x-x_1)}$

$\mathrm{y-38=6(x-5)}$

$\mathrm{y-38=6x-30}$

$\mathrm{y=6x-30+38}$

$\Large\boxed{\sf{ \ y=6x+8}}$

I hope it helps.

Have a nice day.

If 5x-26=x+50, then the value of x is

horsena [70]

Let's work this problem out!

First: 5(x) - 26 - x + 50 = ?

Second: 4(x) - 76 = ?

Third: 4 = ?
↑
(Solve Step 3)

Fourth: x - 19 = 0
↑
(Add the number 19 to each of your sides for Step 4)

Finally we get to your answer

19 + 0 = 19 ; 19 - 19 = 0

So, therefore the value of "x" is 19

$x = 19$
