Answer:
965 km per hour
Step-by-step explanation:
The total distance flown was 193km which was flown at constant speed and took 12 minutes. Dividing 193 by 12 gives us the km per minute
193/12 = 16.0833333
but this isn't the correct answer, this is in km per minute, and the question asked for km per hour. Since there are 60 minutes in an hour, multiply the answer by 60 to calculate how far the plane flew per hour.
16.083333333(60) = 965
A) there is a linear relationship with the test scores go up with increasing hours spent on hw
b) y=8x+40 so at x=3h, y=test score= 8*3+40 = 64
c) 40 represents test score when u spend 0 hour on hw

If the larger angle is x and the smaller angle is y, y=(1/2)x+30 since it's 30 more than 1/2 of it. In addition, x+y=180 since they are supplementary. Plugging y=(1/2)x+30 into that, we get x+x/2+30=180=1.5x+30. Subtracting 30 from both sides, we get 1.5x=150. Next, we can divide both sides by 1.5 to get x=100 and y=(1/2)*100+30=50+30=80
