Answer:
<u>9 mph</u>
Step-by-step explanation:
Calvin's first leg of the trip took 0.5 hr (30 minutes) at 6 mph. That means he travelled (0.5hr x 6 mph =) 3 miles. He travelled 3 miles on the return trip, by definition (same path home). At 18 mph, 3 miles would take (3 miles/18 mph =) 0.1667 hours. That makes a total of 6 miles and (0.5 + 0.1667=) 0.6667 hours.
(6 miles)/(0.6667 hours) = 9 mph is Calvin's average speed for the round trip.
Answer:
It is b
Step-by-step explanation:
1. h(x) = 3
Let f(x) = 3x and g(x) =
2. N(x) = (
)⁵
Let f(x) = x⁵ and g(x) = 2x and h(x) = 
Answer: You simplify it.
Step-by-step explanation: You have to take the numerator and the denominator, find the greatest common factor, and divide it until it is at its simplest form.
