5 + n times of a number
A set is simply the group of numbers.
- <em>The set of M and N are: </em>
<em> and </em>
<em>.</em> - <em>The set of M n N is: </em>
<em>.</em> - <em>The set of M u N is: </em>
<em />
<u>(a) The set of M and N</u>
Given that:
M = squares of integers less than 100
N = Positive odd numbers less than 15
So, we have:
<u>(b) M n N and M u N</u>
M n N is the set of common elements between sets M and N.
So, we have:
M u N is the set of all elements in sets M and N.
So, we have:

28/80 and then you simplify it by dividing the numerator and denominator by 4 and you get 7/20.
B. 7/20 is the correct answer
On the top problem: Angle A and Angle B are a right angle so it equals 90 degrees. If Angle B is 50 degrees that makes Angle A 40 degrees. Angle A and Angle C is a straight line and equals 180 degrees so if Angle A equals 40 degrees that means Angle C equals 140 degrees.
Find the length of the field first. To do this, write a formula for the perimeter, P, of the field: P = 210 ft = 2(45 ft) + 2L.
Then 2L = 210 - 90 = 120, and L = 60 (feet).
The area of the field is thus WL = (45 ft)(60 ft) = 2700 sq ft
