I would say the correct answer is 1728.
The figures are increasing by half each week. To calculate the figure for the 11th week you could use this sum: 20×1.5^11
20 is the starting figure. 1.5 is the multiplying factor to get the figure for the next week and the 11 is the number of weeks.
I hope this helps.

Answer:
The volume of the kiosk is 72 m³.
Step-by-step explanation:
The volume of the kiosk is given by the sum of the volume of a cylinder () and the volume of a cone ():
Where:
r: is the radius of the cylinder and the cone = d/2 = 5/2 = 2.5 m
d: is the diameter = 5 m
: is the height of the cylinder = 3 m
: is the height of the cone = 2 m
Hence, the volume is:
Therefore, the volume of the kiosk is 72 m³.
I hope it helps you!
Answer:x=9
Step-by-step explanation:
To find the positive solution for this, then we will say;
Let the number be x
3x<x^2-54
x^2-3x-54<0
Then we are going to factorise
x^2-9x+6x-54=0
(x^2-9x)+(6x-54)=0
x(x-9)+6(x-9)=0
(x+6)(x-9)=0
Therefore, The positive solution for this is: x=9
