Answer: Required expression is given by
Step-by-step explanation:
Since we have given that
Number of miles per week Elia is training for her first marathon = 10 miles
According to question, we have given that she wants to increase her mileage by 2 miles every week.
so, Equation becomes
10,12,14,16..........
Let the number of weeks be x
Since it forms an Arithmetic sequence,
As we know the formula for nth term :
So, our required expression will be
Answer:
it is increasing because you have more pieces

Answer:
No, the rate is not proportional.
Step-by-step explanation:
If there are 45 marbles in 9 bags, we can assume that there are 5 marbles in each bag.
Going by that rate, we can do 5 * 36 = 180, NOT 150.
Thus, the rate is not proportional.
Another way to solve would be to do 45/9 and 150/36. If the rate is proportional, the answer for both should be the same.
However, 45/9=5 and 150/36=4.16666666667.
Those two answers are NOT equal.
Thus, the rate is not proportional.
Answer:
6042915 balls.
Step-by-step explanation:
Volume of a ping pong ball is;
V = (4/3)πr³
diameter of ping pong ball is given 4cm = 0.04 m
Radius; r = 0.04/2 = 0.02 m
V = (4/3)π(0.02³)
V = 0.00003351032 m³
Room is 9.5 meters long, 7.5 meters wide, and 3 meters high.
Volume; V = 9 × 7.5 × 3 = 202.5 m³
Number of ping pong balls that will fit into the room = volume of room/volume of ping pong balls = 202.5/0.00003351032 = 6042914.540956151
Approximately 6042915 balls.
