Answer:
9
Step-by-step explanation:
1 feet is 12 inches, so 12 feet is 12 * 12 = 144 inches.
If studs are placed 18 inches apart, in 144 inches, there will be:
<u><em>But remember, there is a stud at the very beginning (at 0 feet).</em></u>
<u><em /></u>
So in total there are going to be 9 studs

Answer:
0 is not an element of an empty set.
Step-by-step explanation:
We are asked to determine whether 0 is not an element of an empty set.
We know that an empty set is an unique set having no elements. The cardinality of an empty set is 0.
Cardinality stands for the count of element is an set. An empty set is denoted by symbols ∅ or { }.
The empty set is like an empty container. The container is there, but nothing is in it.
When 0 is an element of a set, then its cardinality would be 1.
Therefore, 0 is not an element of an empty set.
Answer:
442.5 feet^2
Step-by-step explanation:
So this figure is an octagonal prism.
First off we need to find the area of the two octagons.
The formula for the area is 2(1+ to the square root of 2)a^2.
The a is one side value and in this case it is 4 so plug that in and you get 77.25 feet^2.
The same steps apply for the bottom octagon but we don’t have to do that because it is the same as the top one.
So adding up the two octagons is 154.5 feet^2.
Now time for the rectangles.
In total there are 8 rectangles and a really easy way to do this is finding the area of one rectangle and multiplying that by 8.
So the length is 9 and the width is 4 and when you multiply that together you get 36.
Then multiply 36 by 8 and you will get 288 feet^2.
So when you add up 288 and 154.5 you will get 442.5 feet^2 as your final answer.
