Answer: at 50 mph, she drove for 4 hours.
at 45 mph, she drove for 2 hours.
Step-by-step explanation:
Let t represent the time that she spent driving at 50 miles per hour.
Taylor took 6 hours to drive home from college for Thanksgiving break. This means that the time that she spent driving at 45 miles per hour is (6 - t) hours.
Distance = speed × time
Distance covered while driving 50 miles per hour is
50t
Distance covered while driving 45 miles per hour is
45(6 - t)
Since the total distance that she drove is 290 miles, it means that
50t + 45(6 - t) = 290
50t + 270 - 45t = 290
50t - 45t = 290 - 270
5t = 20
t = 20/5 = 4
At 45 miles per hour, she drove at
6 - 4 = 2 hours

Answer:
B, 0.4 in³
Step-by-step explanation:
A cone's volume is determined with the equation 4/3πr²(h/3). In this case, our radius is 0.5 because the diameter is 1, and our height is 3.5 inches. We plug those values into the equation to get approximately 0.92 in³.
Now for a sphere, the volume is determined by 4/3πr². Our diameter is 1, so our radius is 0.5, and pi is 3.14, so plugging that in we get about 0.52
Now we subtract the 2, 0.92 - 0.52 = 0.4
