How do you do this question?
The buses park on the concrete slab. the slab's edges are 10 yards from the fence. What is the area of the concrete slab?
100 sq yds
how many different triangles can you make from a set of three side lengths
To find the area of the concrete slab, we need to know the dimensions of the slab. The question mentions that the edges of the slab are 10 yards from the fence, but it doesn't specify the shape or dimensions of the slab. Without additional information, we cannot accurately determine the area.
Now, let's move on to your second question. In order to determine the number of different triangles that can be formed from a set of three side lengths, we need to use the triangle inequality theorem. According to this theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
To find the number of different triangles, you need to consider the different combinations of side lengths that satisfy the triangle inequality theorem. Here's how you can do it:
1. Start by choosing three side lengths from your set.
2. Check if the sum of any two side lengths is greater than the third side length. If it is, you have a valid triangle.
3. Repeat this process for all possible combinations of side lengths.
4. Count the number of valid triangles you have found.
Note that the order in which you select the side lengths does not matter. Also, if any two side lengths are equal, you need to be careful because it may not be possible to form a triangle in some cases.
By following these steps, you will be able to determine the number of different triangles that can be formed from a given set of three side lengths.
