Answer:
W = 8 feet
Step-by-step explanation:
The rug is rectangular in shape.
Area of a rectangle = Length x Breadth
Given
Area = 104 square feet
length = 13
Therefore
104 = 13 x w
Divide both sides by 13
104/13 = 13/13 x w
8 = w
W = 8 feet
The rug is 8 feet wide
Bearing in mind that the major axis runs over the y-axis, therefore the "a" component will be under the fraction with the "y", check the picture below.
How is it possible to find an answer with only one given
Answer:80students
Step-by-step explanation:
Using set notation concept,
n(U) be the total number of student = 200
n(AnS') be those that earned Bachelor in Art only= 120
n(A'nS) be those that earned Bachelor in Science only= 40
n(AnS) be students that earned both degrees.
Using the formulae below to calculate n(AnS) first;
n(AuS)=n(A'nS)+ n(AnS)+n(AnS')
200=40+n(AnS)+120
200=160+n(AnS)
n(AnS)=40
This shows that 40students earned bachelor in both degrees
Those that earned Bachelor in science degree will then be n(A'nS)+n(AnS) i.e 40+40 =80students.
NB: A' means complement of A(A not included)
'n' denote intersection and 'u' denote union.
