How many diagonals can be constructed from one vertex of an n-gon? State your answer in terms of n and, of course, justify your answer.
Polygon Diagonals. The number of diagonals in a polygon = n(n-3)/2, where n is the number of polygon sides. For a convex n-sided polygon, there are n vertices, and from each vertex you can draw n-3 diagonals, so the total number of diagonals that can be drawn is n(n-3).

Can you help me understand front end and clusters when u round
Answer:
I really hope this help! Some may call it front end rounding while others call is front end estimating, even though they mean the same thing. When rounding a place value, you need to look to the number to the right of it. Example: Most often a teacher may as you round the number 452 to the nearest ten’s. That number will than be 450. But why? Well as we look at the number, we know we need to round to the nearest ten. So in our case it would be 52. Our rule to remember when rounding is 5 and higher we round-up. Since we are looking at the portion of the number 52, we go right of the tens place to find the number 2. Since the number 2 is not 5 or higher, we round down making it 50. Don’t forget to finish the problem by adding the hundreds back to the original number. Your answer for this problem is 450.
Step-by-step explanation: I really hope this helps i will post the rest in the comment!

Greg currently has 30 and receives a new one every 4 months. As a competition, Mark wants to start collecting ties as well. He buys a tie every month until he has the same amount as Greg. How many months until Mark has the same amount? How many ties are there? Hint: use one variable for “# of months” and one for “# of ties”.
9514 1404 393
Answer:
40 months
Step-by-step explanation:
Let t represent the number of months. Then Greg's tie count (g) will be ...
g = 30 + t/4 . . . . . . average rate of tie accumulation is 1/4 tie per month
And Mark's time count (m) will be ...
m = t . . . . . . . . . . . . average rate of tie accumulation is 1 per month
We want these numbers (g, m) to be equal:
g = m
30 +t/4 = t . . . . . substitute the equivalent expressions
30 = 3/4t . . . . . . subtract t/4
40 = t . . . . . . . . . multiply by 4/3
After 40 months, Mark and Greg will have the same amount of ties.

Jim will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $ 59 and costs an additional$0.13 per mile driven. The second plan has an initial fee of $46 and costs an additional 0.17 per mile driven.
Answer:This problem is about linear equations. We assume Dale drive X miles, and the total cost is $Y, then we can get:
Plan I: Y=38+0.11X
Plan II: Y=49+0.07X
When both plans cost the same, 38+0.11X=49+0.07X. We will get X = 275miles, and Y=$68.25

[tex]20x-40y=0[/tex]
[tex]-[/tex]
[tex]\underline{20x+8y=24}[/tex]
[tex]-48y=-24[/tex]
[tex]\begin{bmatrix}20x+8y=24\\ -48y=-24\end{bmatrix}[/tex]
[tex]-48y=-24[/tex]
[tex]\frac{-48y}{-48}=\frac{-24}{-48}[/tex]
[tex]y=\frac{1}{2}[/tex]
[tex]y = 0.5[/tex] ( 0.5 is the result of rounding 0.5 to the nearest 0.01)
[tex]\mathrm{For\:}20x+8y=24\mathrm{\:plug\:in\:}y=\frac{1}{2}[/tex]
[tex]20x+8\cdot \frac{1}{2}=24[/tex]
[tex]20x+4=24[/tex]
[tex]\frac{20x}{20}=\frac{20}{20}[/tex]
[tex]x=1.00[/tex] ( 1.00 is the result of rounding 1 to the nearest 0.01 )
So, the solution is:
(x, y) → (1.00, 0.5)
Question 10)
Similarly the question 10 can be solved.
Given the equations
[tex]5x+2y=9;\:4x-3y=44[/tex]

[tex]\underline{20x+8y=36}[/tex]
[tex]-23y=184[/tex]
[tex]\begin{bmatrix}20x+8y=36\\ -23y=184\end{bmatrix}[/tex]
[tex]-23y=184[/tex]
[tex]y=-8.00[/tex] ( -8.00 Rounded to the nearest 0.01 or the Hundredths Place )
[tex]\mathrm{For\:}20x+8y=36\mathrm{\:plug\:in\:}y=-8[/tex]
[tex]20x+8\left(-8\right)=36[/tex]
[tex]20x=100[/tex]
[tex]x=5.00[/tex] ( 5.00 Rounded to the nearest 0.01 or the Hundredths Place )
So, the solution is:
(x, y) → (5.00, -8.00)

what is 6 1/8 as a decimal?
Answer:
6.125
Step-by-step explanation:
1/8 is half of 1/4.
1/4 is 0.25
0.25 / 2 = 0.125
6 + 0.125 = 6.125
The mixed fraction 6 1/8 as a decimal form is 6.125.
The correct option is C.
To convert the mixed number 6 1/8 to a decimal, you can follow these steps:
Step 1: Multiply the whole number (6) by the denominator (8): 6 × 8 = 48.
Step 2: Add the numerator (1) to the result from step 1: 48 + 1 = 49.
Step 3: Write the sum from step 2 as the numerator over the original denominator: 49/8.
Step 4: Divide the numerator (49) by the denominator (8): 49 ÷ 8 = 6.125.
Therefore, 6 1/8 as a decimal is 6.125.
The decimal form of a mixed number represents the sum of the whole number and the fraction converted to decimal form. In this case, 6 represents the whole number part, and 1/8 represents the fraction part. By performing the division, you find that the fraction 1/8 is equivalent to the decimal 0.125. Adding this decimal to the whole number 6 gives the final result of 6.125.

Are the ratios 4:6 and 6:9 equivalent?
Answer: No
Step-by-step explanation:
Yes, the two ratios 4:6 and 6:9 are equal to 2:3.
What is a ratio?A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a dish of the fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six.
Given that there are two ratios 4:6 and 6:9. The equivalence of the two ratios will be calculated as:-
4 : 6 = ( 2 x 2 ) ÷ ( 2 x 3 )
4 : 6 = 2 : 3
6:9 = ( 2 x 3 ) ÷ ( 3 x 3 )
6: 9 = 2 : 3
4 : 6 = 6:9 = 2:3
Therefore, the two ratios 4:6 and 6:9 are equal to 2:3.
