Answer:
is this science?
Step-by-step explanation:
120% of 12 is 14.4.I got this by doing this:
12/x=100/120
<span>(12/x)*x=(100/120)*x - </span>we multiply both sides of the equation by x
<span>12=0.833333333333*x - </span>we divide both sides of the equation by (0.833333333333) to get x
<span>12/0.833333333333=x </span>
<span>14.4=x </span>
<span>x=14.4</span>
Answer: 9
Step-by-step explanation:
Use Pythagorean's Theorem for a right triangle.


Step-by-step explanation:
x=90°
SUM OF ALL ANGLES OF PENTAGON =540
90+2(180-Y)+105+113=540
90+360-2Y+105+113=540
488-2Y=540
For 1 hour, money = $20
For $140, it would be: 140/20 = 7 hours.
So, option C is your final answer.
Hope this helps!
