Answer:
l = 11.19 feet
Step-by-step explanation:
Given that,
The width of a roll of gasket material, b= 16 inches
We need to find the length needed to obtain 15 sq ft of the material.
We know that,
1 foot = 12 inches
⇒ 16 inhces = 1.34 feet
For a rectangular shaped object, area is given by :
A = l×b
So, the required length is 11.19 feet.
1100/2
=550
because 100% is 500 and 100% is last year's population
U= {A,B,C,D,E,F,G}
X = {A, B, C, D}
Y = {A, C, E, F}
a) X or Y = {A, B, C, D} and {A, C, E, F} = {A, B, C, D, E, F}
B) X and Y = {A, B, C, D} or {A, C, E, F} = {A, C}
c) Complement of X = {A,B,C,D,E,F,G} - {A, B, C, D} = {B,D,G}
