Answer:
Option B
Step-by-step explanation:
To solve this, the Pythagorean Theorem is needed. For option A, to make the statement true, 4 squared plus 7 squared MUST equal 9 squared. So, if you take 16 and add 49 to it you do NOT get 81.
For option B, 5 squared plus 12 squared is the same as 25 plus 144. That equals 169, which IS 13 squared.
It is not option C because 20 squared plus 22 squared doesn't equal 24 squared
Answer:
4 hours
Step-by-step explanation:
X: Working hours by full-timer workers
Y: Working hours by Part-timer workers
Following the problem:
Y=2 and X-Y=2
so, clearing the equation and replacing Y value in it
X=2+Y => X=4 hours
The correct answer would be B because .47 is bigger than 42/100 or .42
