Total weight=number of pennies times weight of 1 penny
total weight/weight of 1 penny=number of pennies
636.3/3.03=210
210 pennies

Answer:
Step-by-step explanation:
The equation of the straight line passing through the points (0,-7) and (3,-5) will be 
⇒ 
⇒
......... (1).
Now, the inequality shades the upper portion of the straight line.
Therefore, the y value for the inequality will be more than y value for the equation corresponding to a fixed value of x.
Hence, the inequality equation will be . (Answer)
So, we are given the speed in mi/min. We want to convert this to mi/hr. We can do this through cross multiplication.
(11 miles/1min) * (60min/hr) = 660 mi/hr
Now, we need to find the total distance flown:
TD= 6 trips*(500 miles/1 trip) = 3,000 mi
Lastly, we find total time using our converted speed and total distance.
speed = (total distance (in miles))/(total time (in hours))
660mi/hr= 3000mi / t
660t=3000
t=3000/660
t= 4.54 hrs
Answer: The plane will fly a total of about 4 and a half hours.
