441ft² (i believe this is the answer, idk though, i might be wrong sorry)
14.99 *3 = 44.97
44.97*1.06 =47.6682, round off to $47.67 with tax
To multiply two fractions, you simply multiply numerators and denominators together.
2 can be read as the fraction 2/1
So, the multiplication is

Question 14 is (1,4)
15 rectangle
hope I helped
Answer:
Power generated = 4.315 kW
Step-by-step explanation:
Given,
- speed of wind when enters into the turbine, V = 12 m/s
- speed of wind when exits from the turbine, U = 9 m/s
- mass flow rate of the wind, m = 137 kg/s
According to the law of conservation of energy
Energy generated = change in kinetic energy
Since, the air is exiting at same elevation. So, we will consider only kinetic energy.
Energy generated in one second will be given by,


=4315.5 J
= 4.315 kJ
So, energy is generated in one second = 4.315 kJ
Power generated can be given by,

And the energy is generated is already in per second so power generated will be 4.315 kW.
