Answer:
c
Step-by-step explanation:
180-24-30=126
3x-9=126
3x=135
x=45
5/6, 5/12, 19/45, 13/14, 19/21, 1/2, 4/9
Most of the information's required for finding the perimeter of the rectangle is already given in the question. Based on those details the answer to the question can be easily determined.
Length of the rectangle in question = 11 meters
Width of the rectangle in question = 4 meters
Then
Perimeter of a rectangle = 2 ( Length + Width)
= 2 (11 + 4) meters
= 2 * 15 meters
= 30 meters
So the perimeter of the rectangle in question is 30 meters as can be seen from the above deduction.
9514 1404 393
Answer:
48.6%
Step-by-step explanation:
Efficiency of energy conversion is the quotient of output energy and input energy.
(3291 J)/(6771 J) × 100% ≈ 48.6%
The solar panel's conversion efficiency is about 48.6%.
_____
<em>Additional comment</em>
With current (2021) technology, the best efficiency one can expect from a solar panel is in the neighborhood of 23%.
265.22 or 265 2/10 or 265 1/5
