Answer:
592 hours
Step-by-step explanation:
Given


Required
Determine the time taken to cover the area
Since, the oil formed a circular pattern; the question will be answered using area of a circle

Let t represent the time take to cover 11000m²;
The relationship between these parameters is:

Substitute 3.14 for π

Divide both sides by 3.14



Take square root of both sides



Divide both sides by 0.10




<em>(</em><em>Approximated)</em>
<em>Hence, it'll take approximately 592 hours to cover the given area</em>
The answer for your question is going to be. 2^((3)/(2)) I know this cause I just took a quiz with this question on it
Answer:
Angle EFG = 104 degrees
Angle GFH = 76 degrees
Step-by-step explanation:
Angle EFG and Angle GFH are a linear pair, which means that they add up to 180 degrees.
Angle EFG = 4n + 20 and Angle GFH = 2n + 34, so 4n + 20 + 2n + 34 = 180.
We can then combine like terms, getting 6n + 54 = 180.
Then, we can subtract both sides by 54, getting 6n = 126.
Lastly, we can divide both sides by 6, getting n = 21.
EDIT - solve for EFG and GFH:
Angle EFG = 4n + 20 = 4(21) + 20 = 104 degrees
Angle GFH = 2n + 34 = 2(21) + 34 = 76 degrees
