There is no "last term." Since the pattern is increasing by .03 each time, then the pattern continues forever.
First compute the perimeter of the pool:
(21+33)*2=108 foot.
Since the material cover 232 ft^2, then it is sufficient to divide the above number over the length of the border like this:
232/108=2.1
The trip can be 2.1 ft in wide.
Answer: Mrs. Jefferson should plan to spend 119.1 on wallpaper
Step-by-step explanation:
She would like to wallpaper everything but the door. It means that the area to be covered by the wallpaper would be the area of the 4 walls of the room - the area of the door.
The room is 18ft in length and 12ft in width. Thea area of each side of the room is
18 × 12 = 216 square feet
Area of the 4 sides of the room is
216 × 4 = 864 square feet
The door is 7ft in width and 3 ft in length. Area of door is
7 × 3 = 21 square feet
Area to be covered is
864 - 21 = 843 square feet
Each roll of wallpaper covers approximately 160 square ft. Therefore, the number of rolls needed is
843/160 = 5.26
Since the rolls cannot be a fraction, then she needs 6 rolls
Since a roll costs 19.85, the cost of 6 rolls is
19.85 × 6 = 119.1
