ChoiceD: a circle graph titled social media usage, with four sections labeled picturegram 17 percent, tweeter 48 percent, vidtok 25 percent, and headbook 10 percent
Answer:
The answer to your problem is, B. a circle graph titled social media usage, with four sections labeled vidtok 17 percent, headbook 48 percent, picturegram 25 percent, and tweeter 10 percent
Step-by-step explanation:
By adding all the numbers you get 500, but you need to make it 100% so you divide the total number by five. To know what percent out of 100 you need to divide all of the variables by 5.
85 ÷ 5 = 172
40 ÷ 5 = 48
125 ÷ 5 = 25
50 ÷ 5 = 10
Thus the answer to your problem is, B. a circle graph titled social media usage, with four sections labeled vidtok 17 percent, headbook 48 percent, picturegram 25 percent, and tweeter 10 percent

Triangle D has been dilated to create triangle D′. Use the image to answer the question.
Answer:
To find the scalar value, simply choose one side of D and one did of D’ and divide them to find the scalar. We can verify that we have the correct scalar by performing this division on each related edge. Below I will do D to D’ represented like D/D’:
4.8 / 1.2 = 4
5.2 / 1.3 = 4
3.6 / x = 4
Knowing that the scaling for each edge is 4, we can solve for x.
3.6 / 3 = x
1.2=x
So we know the edges for D are 4.8, 5.2, and 3.6 respectively to D’ scaled by 1/4. So we can determine that the edges for D’ are 1.2, 1.3, and 1.2 respectively to D scaled by 4.
So if we go D’ to D, we scale by 4. If we go D to D’, we scale by 1/4.

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143

Describe how the data is dispersed in a box plot with the following data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24.
AND PLEASE ACTUALLY EXPLAIN/DESCRIBE!
In a box plot, also known as a box-and-whisker plot, the data is dispersed and represented visually to provide a summary of the distribution and key characteristics of the dataset. Let's describe how the data is dispersed in the box plot for the given data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24.
1. Median (Q2): The median represents the middle value of the dataset when arranged in ascending order. In this case, the median is around 27 or 28, as it lies between the values 27 and 30.2. Lower Quartile (Q1): The lower quartile marks the boundary between the lower 25% of the data and the upper 75%. It is located approximately around 22 or 23, as it falls between the values 21 and 24.3. Upper Quartile (Q3): The upper quartile marks the boundary between the lower 75% of the data and the upper 25%. It is located around 34 or 35, as it lies between the values 33 and 36.4. Interquartile Range (IQR): The IQR is the range between the upper and lower quartiles (Q3 - Q1). In this case, the IQR is approximately 12 (35 - 23).5. Whiskers: The whiskers represent the range of the data excluding any outliers. They extend from the lower quartile (Q1) to the minimum value and from the upper quartile (Q3) to the maximum value. However, in some cases, the whiskers can also be defined based on certain criteria, such as 1.5 times the IQR. Outliers, if present, are depicted as individual data points beyond the whiskers.6. Outliers: Outliers are data points that significantly deviate from the rest of the dataset. In this case, there are no clear outliers based on the data provided.7. Box: The box in the box plot spans from the lower quartile (Q1) to the upper quartile (Q3) and represents the middle 50% of the data. In this case, the box spans approximately from 23 to 35.By observing the box plot, we can see that the data is moderately dispersed, with the majority of values concentrated around the median. The range of the data is approximately 20 to 38, with some variability within the dataset.

The side lengths of a triangle area are 5, 3, and 4. Is this a right triangle?
(question and answers attatched)
Answer:
C
Step-by-step explanation:
We can use the Pythagorean Theorem to find if this really is a right triangle.
3² = 9
4² = 16
5² = 25
9 + 16 (?) 25
9 + 16 = 25
Your answer would be C.
Hope this helps. Have a nice day.
Answer:
C.)Yes because \(3^{2} + 4^{2} = 5^{2}\)
Step-by-step explanation:
The Pythagoras theorem should be applied in this question. This theorem can only be applicable if the triangle has a right angle ( 90° ) therefore it is used.
\(a^{2} + b^{2} = c^{2}\) (The Pythagoras theorem)
\(3^{2} + 4^{2} = 5^{2}\)
\(3^{2}\) = 9 and \(4^{2}\) = 16. So,
9 + 16 = 25 and \(5^{2}\) = 25
∴ The sides proves that it is a right angled triangle.

Please Help and Explain this like how do I calculate income tax and capital gain and investments
Answer: down below...
Step-by-step explanation:
Exercise 1:
Income = $83.465
Tax paid at 5.05% means, whatever your income is, you gotta pay 5.05% of it as a tax.
5.05% = \(\frac{5.05}{100}\)
\(\frac{5.05}{100}*$83.465\)
\(0.0505*$83.465\)
If you do the calculations it should give you a $4,214.9825 tax
"Income tax paid at 9.15%"
\(\frac{9.15}{100}*83.465\)
\(0.0915*83.465\)
The 9.15% tax = $7,637.0475
"Total income tax paid"
This will just be the sum of the two taxes.
$4,214.9825+$7,637.0475 = $11,852.03 (sum of taxes)
Exercise 2:
Purchase price = $347.000
Selling price = $863.000
As you can see, they purchased the property for $347.000 and sold it for $863.000 which made them a lot of money in profit :)
That's what the Difference is.
Difference = $863.000-$347.000
Difference = $516,000
I don't really understand what capital gains are, because I'm 13, but I suppose I gotta calculate 50% of the profit that the banker has made.
\(\frac{50}{100}*$516.000\)
\(\frac{5}{1}*$51.600\)
\(5*$51.600\)
"Capital gains" = $258,000
I don't really know if this is the correct answer for capital gains, but I am pretty sure I did well on the other ones.
Hope I helped you :] !

Identity Property:Additional and Multiplication.
Distributive PropertyStep-by-step explanation:
Communitive Property:
Addition; When two numbers are added, the sum is the same regardless of the order in which the numbers are added. (3 + 2 = 5 or 2 + 3 = 5)
Multiplication; When two numbers are multiplied together, the product is the same regardless of the order in which the numbers are multiplied.
(4 x 3 = 12 or 3 x 4 = 12)
Associative Property:
Addition; When three or more numbers are added, the sum is the same regardless of the way in which the numbers are grouped.
6 + (4 + 3) = 13 or (6 + 4) + 3 = 13
Multiplication; When three or more numbers are multiplied, the product is the same regardless of
the way in which the numbers are grouped.
6 x (4 x 3) = 72 or (6 x 4) x 3 = 72
Identity Property:
Addition; The sum of any number and zero is that number.
(10 + 0 = 10)
Multiplication; The product of any number and one is that number.
(33 x 1 = 33)
Distributive Property:
The sum of two numbers times a third number is equal to the sum of each addend times the third number. 6(3 + 4)
(Multiply 6 by both numbers, 6 x 3 = 18 and 6 x 4 = 24, and then add the sums; 18 + 24 = 48.

Find the volume of the cargo hold and the volume of one box.
When you load one box, the space of the cargo hold will reduce. So when you add more boxes, the space of cargo hold will reduce continuously. So continuous subtraction is divsion.
To find the number of boxes, divide the volume of cargo hold by the volume of each box.
Number of boxes = Volume of cargo hold÷ volume of one box
