The ration of minutes to hours is 60/1
Therefore, 8gal/60min = (2/15)gal/min
Answer:
X=67°,Z=113°,Y=0°
Step-by-step explanation:
2.1=
X+113°=180°(being straight angle)
Or, X=180°-113°
Or,X=67° answer
Now,
Z=113°(being alternative angle)
Again,Y+Z+X=180°(being co-interior angle)
Or, Y+113°+67°=180°
Or,Y+180°=180°
Or,Y=180°-180°
=Y=0° answer
It would be graph W because the cost will increase, so that gets rid of Y... It has to start at 40 for the original cost, getting rid of Z and X
