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
Answer:
x<-21

x/7<-3
x<-21
Answer:
81 in
Step-by-step explanation:
The watercolor painting area:
width x length = the formula for the area of a rectangle.
9 x 15= 135
The mat area:
15 + 3= 18
9 + 3= 12
12 x 18 = 216
<u>216 - 135 = 81</u>
Answer:
On Sunday they traveled=1/7 of the total distance
Step-by-step explanation:
Total distance to be traveled=x
On Saturday they covered=(5/7)x
Remaining distance=x-(5/7)x=(2/7)x
Sunday=1/2 of the remaining distance=(1/2)×(2/7)x=(1/7)x
On Sunday they traveled=1/7 of the total distance(x)
