Using the edge lengths already given, I calculated the height of the right side of the irregular octagon by adding the heights on the left. Since they added to 9m, then I put 9 on the edge with a missing height. To find the missing length, I subtracted the quantity of 6+6 from 18 (you can also divide 18 by 3) to get 6. Now that I know all the lengths, I can add them to get the perimeter. Since 3+3+3+6+6+6+9+18, or (3*3)+(6*3)+9+18 is equal to 54, our answer is 54.

How to solve shaded regions on a trapezoid is simple.
First find the area of the whole trapezoid, or W but it already gives us that as 21.66 in squared.
Next, find the area of the non shaded region, or NS.
3.8*4.6=17.48 in
Lastly, subtract the NS from the W.
21.66 -17.48 =
NS= 17.48 in squared.
W= 21.66 in squared.
S= 4.18 in squared.

The answer is B- 4.18 in Squared

A company making backpacks charges $29.99 for each backpack. It costs $6.45 to make each backpack. The company can make backpack

Ne4ueva [31]

A minimum of 220 backpacks must be produced to obtain the desired benefits.

Since a company making backpacks charges $ 29.99 for each backpack, and it costs $ 6.45 to make each backpack, and the company can make backpacks in multiples of 10 and there is $ 1,000 in fixed costs, and the company wants to make at least $ 4,000 profit each week, to determine how many backpacks should be produced, the following calculation must be performed:

29.99 - 6.45 = 23.54
500 x 23.54 - 1000 = 10,770
250 x 23.54 - 1000 = 4.885
220 x 23.54 - 1000 = 4,178.80
210 x 23.54 - 1000 = 3,943.40

Therefore, a minimum of 220 backpacks must be produced to obtain the desired benefits.

Simplify 2a^2b^3 (4a^2 + 3ab^2 - ab) =?

stellarik [79]

The correct answer is D.D. 8a^4b^3 + 6a^3b^5 - 2a^3b^4

You can tell this by the lead term alone. When you mutliply the term outside to the lead term, D is the only one that has that term.

2a^2b^3*4a^2 = 8a^4b^3

D. 8a^4b^3 + 6a^3b^5 - 2a^3b^4

<h3>Answer: Choice (3) 28</h3>

==========================================================

Explanation:

We start with one block at the very left side. This is algebraically written as $a_1 = 1$ . The small subscript '1' means we're dealing with the first term, and that is set equal to 1. In other words, the first term is 1.

The second term is three since we have three blocks as the next figure down the line. So $a_2 = 3$ . We can then see that $a_3 = 6$ and $a_4 = 10$

The sequence of the first four terms are: 1, 3, 6, 10.

The notation $a_n = a_{n-1} + n$ tells us "to get the nth term $a_n$ , we add the previous term ( $a_{n-1}$ ) to the value of n".

For example, if we wanted the third term, we would add the second term a2 onto the value of n = 2. In order to know a2, we need the diagram or you would have to use the recursive formula to find it.

Furthermore, it means that to find the fifth term $a_5$ , we do the following

$a_n = a_{n-1} + n\\\\a_5 = a_{5-1} + 5\\\\a_5 = a_{4} + 5\\\\a_5 = 10+5\\\\a_5 = 15$

The fifth figure will have 15 small little blocks to it. You can draw this out by copying the fourth figure, and then adding 5 smaller blocks to the very bottom portion. The sixth figure is basically a copy of the fifth one, but we have six little blocks along the bottom. This is the "plus n" being applied in the recursive formula.

So the 6th figure will have 15+6 = 21 blocks in total while the 7th figure has 21+7 = 28 blocks. This points us to choice (3).

Side note: These are known as triangular numbers. Note how the gaps between consecutive values of 1,3,6,10,15,21,28 is +2,+3,+4,+5,+6,+7.
