Answer:
<u>The correct answer is 58.82 square meters of solar panels will be needed to supply 2 kilowatts</u>
Step-by-step explanation:
Solar cell energy supply = 34 watts per square meter
Therefore, 100 square meters will supply 3400 watts which is 3.4 kilowatts.
How many square meters of solar panels would you need to 2 kilowatts?
Total energy = 2 kilowatts = 2,000 watts
Number of square meters = Total energy/Solar cell energy supply
Number of square meters = 2,000/34
<u>Number of square meters = 58.82</u>
<u>It will be necessary 38.82 square meters of solar panels to supply 2 kilowatts</u>
Answer:
(2, - 4 )
Step-by-step explanation:
Given the 2 equations
10x + 7y = - 8 → (1)
7x + 7y = - 14 → (2)
Subtract (2) from (1) term by term to eliminate y
(10x - 7x) + (7y - 7y) = - 8 - (- 14) , that is
3x = 6 ( divide both sides by 3 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (1)
10(2) + 7y = - 8
20 + 7y = - 8 ( subtract 20 from both sides )
7y = - 28 ( divide both sides by 7 )
y = - 4
solution to the system of equations is (2, - 4 )
Answer:
I think it's alternate interior, cause both the angle are inside..
