Option B:

$\frac{9{s^2} }{4 {m^3} {p^6}}

Solution:

Given expression:

$\frac{9 m^{-3} p^{-6}}{4 s^{-2}}

To write this expression without negative exponents:

$\frac{9 m^{-3} p^{-6}}{4 s^{-2}}

Using exponent rule: a^{-b}=\frac{1}{a^b}

$m^{-3}=\frac{1}{m^3}

$p^{-6}=\frac{1}{p^6}

$s^{-2}=\frac{1}{s^2}

Substitute these in the expression.

$\frac{9 m^{-3} p^{-6}}{4 s^{-2}}=\frac{9 \frac{1}{m^3}  \frac{1}{p^6} }{4 \frac{1}{s^2} }

Denominator of fraction in denominator goes to numerator.

Denominator of fraction in numerator goes to denominator.

Therefore, s^2 goes to numerator and m^3p^6 goes to denominator.

               $=\frac{9 \times {s^2}   }{4 {m^3}\times{p^6}}

              $=\frac{9{s^2} }{4 {m^3} {p^6}}

Option B is the correct answer.

$\frac{9 m^{-3} p^{-6}}{4 s^{-2}}=\frac{9{s^2} }{4 {m^3} {p^6}}

sveta [45]

Answer:

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

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

<u>13'200,000 * 365 = 4,818'000,000 kilowatt-hours per year</u>

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)

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