Answer:
We have 300 edges and 200 vertices
Step-by-step explanation:
A prism is basically a 2D shape which extends into three dimensions. Thus, it has two end faces, and one face for each side on the original shape.
In addition to the two 100-sided polygons at top and bottom, the prism will also have 100 rectangular faces.
We will solve this by Euler’s formula which ks:
V - E + F = 2
where;
V is the number of vertices (corners),
E is the number of edges
F is the number of faces (of any polyhedron).
Number of vertices is 100 surrounding the top while it's 100 at the bottom. So total V = 100 + 100 = 200 .
The number of edges is 100 at the top, and 100 at the bottom. Also an additional 100 separating the hundred vertical faces.
Total number of edges is;
E = 100 + 100 + 100 = 300.
Thus, we have 300 edges and 200 vertices

8/9 miles per hour
1 5/12 miles per hour
Answers
Answer:
The hiking speed in miles per hour is 1 1/8.
Step-by-step explanation:
This can be solved by a simple rule of three.
In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.
When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too.
When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease.
In this problem, the measures are the time spent hiking and the distance hiked. As the the time spent hiking increases, so will the distance hiked. So their relationship is direct.
So:
3/4 - 2/3 hour
x miles - 1 hour
x can also be written in this format
So the hiking speed in miles per hour is 1 1/8.

Answer:
decimal format = 29.25
mixed number = 29 1/4
Improper fraction = 117/4
Step-by-step explanation:
Make the denominators equal after simplifying the denominators*. The denominators are currently 2 and 4. So you can just make your life easier by making the denominator of the first number a 4. Multiply both sides by 2.
1. Simplify
12*2+1 = 25/2
25/2*2/2 = 50/4
2. Simplify second number
16*4+3 = 67/4
3. Add the improper fractions
50/4 + 67/4 = 117/4
Total answer:
29.25 = decimal format
mixed number = 29 1/4
Improper fraction = 117/4
Terms:
*denominators - the bottom number of a fraction

Those lengths have a common factor of 3. Removing that factor gives you the smaller similar triangle with sides 2, 3, and 4.
