Y=Mx+b (m is slope, b is y-intercept)
Answer:
Distance = 70 + 55 = 125 kilometers
Time = 4 + 3 = 7 hours
Rate = Distance / Time
Rate = 125 / 7 = 17.8571428571 kilometers per hour
Step-by-step explanation:
The hours worked would be 7 and 10 minutes.
Answer <span>B.X= 3 1/8
</span><span>X+7/8=4
x = 4 - 7/8
x =3 8/8 - 7/8
x = 3 1/8</span>
V = (pi)r^2h / 3
= (pi)10^2(81) / 3
= (pi)(100)(81) / 3
= (pi)(8100) / 3
= (pi)2700
So C.
