Describe how to organize 100 toothpicks in a way that fits with the structure of the base ten system. Explain how your organization reflects the structure of the base ten system and how it fits with the way we write the number 100.
The way to organize 100 toothpicks in a way that fits with the structure of the base ten system as well as how your organization reflects the structure of the base ten system and others is given below.
Put all the toothpicks in bundles of ten first. After that, combine those 10 bundles of 10 into one bundle. The base-ten system is built on this recurrent bundling in groups of ten. The huge bundle of 10 bundles of 10 represents the 1 in 100.How do you explain base-ten?According to the base-10 system, each digit of a number can, depending on its position, have an integer value ranging from 0 to 9 (10 possibilities). Powers of 10 are used to determine the locations or positions of the numbers. The term "base-10" refers to a system of numbers where each place is 10 times the value to its right.
Since we have 10 fingers, we employ the base 10 system. Since base 10 only uses the numerals 0 through 9 for its ten digits, students start to realize that there are only 0-9 digits in each place value.
Therefore, This becomes very vital while adding and subtracting since, depending on the operation, if we have a digit larger than 9, we must either regroup or ungroup to make it less than 10.

Find the value of x
Answer: The value of x is 49.
Step-by-step explanation:
To find the value of x, you will first need to cross multiply the fractional variables together.
5x - 80 = 3x + 18
Then, move the numerical term 80 to the right side of this equation and add it to 18.
5x - 80 = 3x + 98
Move 3x to the left side of the equation and subtract it this time to the variable 5x.
2x = 98
Finally, you divide both of the equation's sides by 2 and you will get 49.
x = 49
When you actually add x to this problem, you would get 33/55.
49 - 16/49 +6 = 33/55
You can then simplify 33/55 and get the same answer 3/5.
3/5
Therefore, the value of x for this variable equation with the fractions would be equal to x = 49. Hope this helps!

Tanya’s gross pay this pay period is $2,100. She is expecting $300 to come out for taxes and insurance. What should her net pay be on her paycheck?
Answer:
1800
Step-by-step explanation:
if 300 is all that is being subtracted from her gross pay then it should just be 2100-300=netpay
After deducting the tax and insurance from the gross pay, the net pay that will be on Tanya's paycheck is $1,800.
Given parameters:
Tanya's gross pay = $ 2,100
Estimated amount for tax and insurance = $300
To find:
the net pay on her paycheckTanya's net pay after deducting the tax and insurance is calculated as;
The net pay = Gross pay - tax and insurance
The net pay = $ 2,100 - $300The net pay = $1,800Thus, the net pay that will appear on Tanya's paycheck is $1,800.

a jar contains five popsicle sticks, numbered 1-5. a stick is drawn, then a letter in the spring is chosen at random.. draw a tree diagram,list the the sample space, and, and give the number of outcomes
The total number of outcomes as obtained from the sample space is 30.
How to create the tree diagramFrom the question, we have:
Sticks = 5
Word = SPRING
From the above, we have:
Popsicle sticks = 1, 2,3,4,5
Letters of "SPRING" = S, P, R, I, N, G
Creating the sample space (S), we have
S = {S1, S2, S3, S4, S5, P1, P2, P3, P4, P4, R1, R2, R3, R4, R5, I1, I2, I3, I4, I5, N1, N2, N3, N4, N5, G1, G2, G3, G4, G5}
The sample space is created by selecting a letter from the word and a number from the list
Counting the number of samples in the space, we have
Outcomes = 30
This means that the total number of possible outcomes is number of total occurrences in the sample space which is 30.
Hence, the number of outcomes is 30.

certain day, 5 times as many children attend the show than adults, and the total revenue is
$94,908. About how many adults bought tickets?
Let the number of adults equal x, and the number of children equal 5x.
26(5x) + 69x = 94908
194x = 94908
x = approx. 489
About 489 adults bought tickets.
A total of 489 adults take tickets to the circus & Fan Fair show.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say the number of tickets that adults bought is a and the number of tickets that children bought is c.
Then,
26(5a) + 69c = 94908
194a = 94908
a = 489.21 but we need to take the whole number and practical number so it will be 489.

One of the sides of a pentagon has length 12. Which of the following points, when paired with (2, 3), will make a side equal to this length?
A) (14, 15)
B) (2, -9)
C) (-2, -3)
D). (-9, 2)
The correct option for the given sum is option B. The point (2,-9) paired with (2, 3), will make a side equal to this length.
Let the other point of the pentagon will be M(n, o).
The given point be A (a, b)
Also given one of the sides of a pentagon has length 12.
Now, we need to find the distance between the two points,
Distance between two points: |AM| = √\((a-n)^2+(b-o)^2\)
Now,
\(12 = \sqrt{(2-n)^2+(3-o)^2}\)
\((12)^2\) = \((2-n)^2+(3-o)^2\)
\((2-n)^2+(3-o)^2\) = 144 ----------------------------- eq (1)
Now, check every point for the values to match with equation (1)
Option A: \((2-14)^2+(3-15)^2\) = 288. So the option is false.
Option B:
\((2-2)^2+(3-(-9))^2\) =114
0+114 =114
Therefore option B is correct. The other point is (2,-9).

Sample more families/ sample families that have children who are not in seventh grade/ sample families that do not have children /sample families whose answer to the survey question is predetermined/ sample families living in every third house in the neighborhood
The correct options are sample more families, sample families having children who are not in seventh grade.
Sample families that do not have children. Sample families living in every third house in neighborhood.
To increase the validity of the results of Kai's survey, he could make the following improvements to his sample:
Sample more families: Increasing the sample size would make the results more representative of the neighborhood as a whole, reducing the impact of random variation and making the estimates more precise.
Sample families that have children who are not in seventh grade: This would make the sample more diverse and representative of families with children of different ages.
Sample families that do not have children: Including families without children would make the sample more diverse and representative of the entire neighborhood.
Sample families living in every third house in the neighborhood: This would help to ensure that the sample is geographically representative of the neighborhood, reducing the chance of

Note: the answers that were correct have a check mark next to them.
EXPLANATION
As shown in the image, it is correct that AC = AC by the reflexive property.
Then, from the first two statements we can conclude that triangles ABC and CDA are congruent, by SSS:
Then, angles BCA and CAD are congruent because corresponding parts of congruent triangles re congruent (CPCTC).
If we draw the other diagonal as shown in the diagram, we can see that angles BEC and DEA are vertical angles and therefore they are congruent.
Then, we can conclude that triangles BCE and DAE are congruent by AAS:
We know that two consecutive angles and a non-included side are congruent to two consecutive angles and a non-included angle.
Then, segments BE and ED are congruent because CPCTC.
Finally, AC bisects BD by the angle bisector definition.

Joe made a mistake in his calculations by multiplying 28 quarts by 4.
How to illustrate the word problem?To know the mistake that Joe made and the possible correction, we shall convert 28 quart to gallon.
Recall that 4 quart = 1 gallon
Therefore, 28 quart will be:
= 28 quart × 1 gallon / 4 quart
28 quart = 7 gallon
Therefore, 28 quarts is equivalent to 7 gallons.
Hence, Joe made a mistake in his calculations by multiplying 28 quarts by 4 instead of dividing 28 quart by 4.
