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:

The sum of interior angles of a triangle is 180°, and a linear pair is supplementary (adds to 180°). The appropriate choice is
... G. w = 105°, because ...
_____
In short, an exterior angle is equal to the sum of the opposite interior angles.
... w = 180 - (180 - (45 + 60)) = 180 -180 +45 +60
... w = 45 +60
90 words in 4 minutes is the same as 45 words in 2 minutes because you divide both sides by 2. 2 goes into 10, 5 times, so 45x5=225.
You can expect her to type 225 words in 10 minutes.
Answer:
the height of the cross section is 3 feet
Step-by-step explanation:
The computation of the height of the cross section is shown below:
Area = 1 ÷ 2 × (a + b) × h
39 = 1 ÷ 2 × (20 + 6) × h
39 = 1 ÷2 × 26 × h
39 = 26 ÷ 2 × h
39 = 13 × h
h = 39 ÷ 13
= 3 feet
hence, the height of the cross section is 3 feet
