Answer:

The construction of a wind turbine costs around 1.3 to 2.2 MILLION dollars, Most of the commercial-scale turbines installed today are 2 MW in size and cost roughly $3-$4 million installed. Depending on the individual terms of the Power Purchase Agreement, the average wind farmer can make $3,000 to $8,000 per year for the electricity that is produced by each turbine. This amount can be increased to upwards of $10,000 for larger utility-scale turbines with a capacity of two megawatts or more. So it would take around 400 years to just pay OFF a wind turbine if it costs 4 million and the farmer made 10000.

WITCHER [35]

1/4 foot = 3 inches.
The area of a 1/4-ft square is (3" x 3") = 9 square inches.

1/3 foot = 4 inches.
The area of a 1/3-ft square is (4" x 4") = 16 square inches.

The 1/3-ft square tile covers more area than a 1/4-ft square tile
covers. So she won't need as many 1/3-ft tiles to cover the floor
in her room. She will use fewer of those.

A leaky faucet is losing water and is filling a 5-gallon bucket every 20 hours. At that rate how many gallons of water will the

Nesterboy [21]

To solve this problem, let's set up a proportion, letting x represent the unknown number of gallons the faucet loses in 48 hours.

5 gallons / 20 hours = x gallons / 48 hours

To solve this proportion, we are going to use cross-products. This is the products of numerator of one fraction and the denominator of the other fraction set equal to one another. It results in the equation:

5 * 48 = 20 * x

Next we simplify by performing the operations.

240 = 20x

Finally, we divide both sides by 20 to get x alone on the right side of the equation.

12=x

Therefore, 12 gallons of water will be lost in 48 hours.

$s(av) = \frac{∆x}{∆t} \\$

$s(av) = average \: \: speed$

$∆x = covered \: \: distance$

$∆t = time \: \: of \: \: the \: \: covered \: \: distance \\$

The question is incomplete, the complete question is below:

Scientists have found a relationship between the temperature and the height above a distant planet's surface. , given below, is the temperature in Celsius at a height of kilometers above the planet's surface. The relationship is as follows: T(h) = 30.5 -2.5h.

a) Calculate T^-1(x)

b) T^-1(15)

Answer:

a) $T^{-1} (x)= \frac{30.5-x}{2.5}$

b) 6.2 °C

Step-by-step explanation:

a) $T(h) = 30.5 - 2.5h\\2.5h = 30.5-T(h)\\h = \frac{30.5-T(h)}{2.5}\\ T^{-1} (x)= \frac{30.5-x}{2.5}$

b) $T^{-1} (x)= \frac{30.5-x}{2.5}\\\\T^{-1} (15)= \frac{30.5-15}{2.5}=6.2$
