Explanation:
Each face is a polygon representing a wall, ceiling or floor of the 3D structure. If we rotated the figure so that one triangle is flat on the ground we would have...
2 triangles for the floor and ceiling3 rectangles for the wallsThat's 2+3 = 5 faces total.
-----------
The edges connect adjacent faces. For instance, two neighboring walls are connected with an edge. There are 3 edges that connect adjacent walls. There are 3+3 = 6 more edges that connect a wall to either the ceiling or the floor.
That's 3+6 = 9 edges total.
-------------
Vertices are corner points. They are endpoints of segment edges.
The triangular floor provides 3 vertices. The triangular ceiling provides the other 3.
That's 3+3 = 6 vertices total
-------------
Extra info:
Euler's polyhedron formula is
F+V-E = 2
where
V = number of verticesF = number of facesE = number of edgesLet's use that formula for
F = 5 facesV = 6 verticesE = 9 edgesSo,
F+V-E = 2
5+6-9 = 2
11-9 = 2
2 = 2
The formula works for this polyhedron and any other polyhedron. So if you know two of the three items (say the value of F and V), you can use the formula to determine the missing third piece.

1. I took the length and multiplied that by the width to get the area
2.
Answer:
1. C
2. D
Step-by-step explanation:
For question 1 you would multiply 23 by 12 because the area of a rectangle is base * height. To get 276 which is C.
For question 2 you would find the area by doing 1/2(b*h) or 1/2(7*4) which equals 14. To find the area of 4 triangles you would then do 14*4 which equals 96.

What do we divide the numerator and denominator by to simplify
12/30 to lowest terms? (What is the largest number we can divide both the numerator and denominator by?)
Answers
Answer:
The factors of 12 are 1, 2, 3, 4, 6, and 12.
The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.
The largest number that both 12 and 30 have in common is 6.
So, we can divide both the numerator and denominator by 6:
12/30 ÷ 6/6 = 2/5
Therefore, 12/30 simplified to lowest terms is 2/5.
Answer:
Divide the numerator and denominator by 6:
[tex] \frac{12}{30} = \frac{2}{5} [/tex]
Step-by-step explanation:
12 = 2 × 2 × 3
30 = 2 × 3 × 5
GCD of 12 and 30 = 2 × 3 = 6
Directions: Follow the instructions for the following inequalities.
1. 4 < 7 Multiply both sides by 3, then by 2, then by 4, then by 9
2. 11 > -2 Add 3 to both sides, then add 3, then add (-4)
3. -2 less than or equal to -2 Subtract 6 from both sides, then 8, and then 2
4. -4 < 8 Divide both sides by -4, then by -2
5. Write a short explanation of the effects of the above operations. Did this affect the inequality sign? Was it still true? Why or why not?
Answers
Answer:
1. 504 < 1512
2. 12 > 0
3. -2 = -2
4. -1 < 2
Step-by-step explanation:
Given that both sides are being changed by the same amount and sign, the sign never changes. They always have the same value.

Nadia is a stockbroker. She earns 12% commission each week. Last week, she sold $6,400 worth of stocks. How much did she make last week in commission? If she averages that same amount each week, how much did she make in commission in 2011?
Answers
Answer:
Nadia made a commission of 768 last week
The amount she made in 2011 is 40,045.824
Step-by-step explanation:
What is a commission?
A commission is the fee got for the services, given by the percentage of the total worth.
If Nadia gets a 12% commission for $6400,
Commission = percentage × worth of stock
= 12% × 6400
= 768
There are 52.143 weeks per year.
The amount of commissions she made in 2011 is,
768 × 52.143 = 40,045.824
Hence, Nadia made a commission of $852 for $6400 worth of stocks. If she averages the same amount each week, Nadia made a commission of $40,045.824

Create a number line that represents the solution set of the inequality w divided by 7 > 38. Show all your work
Answers
Answer:
Step-by-step explanation:
To represent the solution set of the inequality w divided by 7 > 38 on a number line, we first need to isolate the variable w:
w/7 > 38
w > 7 x 38
w > 266
This means that any value of w greater than 266 satisfies the inequality.
We can represent this on a number line by marking a closed circle at 266 (since the inequality is not inclusive of this value), and drawing an arrow to the right to indicate all values greater than 266:
<--o======(266)---------------->
This represents the solution set of w/7 > 38.
