The perimeter of each figure is 12 cm
Step-by-step explanation:
The question starts by telling you that the perimeters are the same.
So make an equation using the information given.
6(x-1) = 4x
Then solve it.
6x - 6 = 4x Subtract 4x from both sides, and add 6 to both sides.
6x -4x -6 + 6 = 4x-4x + 6 Cancel as necessary -6+6=0 4x-4x=0
2x = 6 .divide both sides by 2
x = 3
To get the perimeters, substitute the value 3 for x in the original expressions:
6(3-1) ==> 6×2= 12 for the hexagon.
4×3 = 12 for the square
The length of ribbons found at a seamstress are listed. 3, 11, 11, 13, 13, 21 What is the appropriate measure of variability for the data shown, and what is its value? The mean is the best measure of variability and equals 11. The median is the best measure of variability and equals 11.5. The range is the best measure of variability and equals 18. The IQR is the best measure of variability and equals 2.
Answer:
(d) The IQR is the best measure of variability and equals 2.
Step-by-step explanation:
You want the best measure of variability of the data set {3, 11, 11, 13, 13, 21}.
VariabilityMean and median are measures of the center of the set of data, not its variability. The variability is measured by the range, interquartile range (IQR), or standard deviation.
Here, the range is the difference between the maximum and minimum values, 21 -3 = 18. The quartiles are 11 and 13, so the IQR is 13 -11 = 2.
OutliersThe minimum and maximum values are more than 1.5×IQR = 3 away from the upper and lower quartile values, so can be considered to be outliers. When we exclude the outliers from the data set, we have ...
{11, 11, 13, 13}
The best measure of the variability is the IQR, which is 2—corresponding to choice 4.

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

A toy company's total payment for salaries for the first two months of 2012 is $40,765. Write and solve an equation to find the salaries for the second month if the first month’s salaries are $10,205.
Answer:
its D
12,455 + x = 23,894
x = 10,560
Step-by-step explanation:
Let's say that the variable 'x' represents the salaries for the second month, so out equation would be:
10,205 + x = 23,894
To solve, we must isolate the variable by subtracting 12,455 from both sides:
10,205 + x = 23,894
-10,205 -10,205
x = 10,560
So, the second month's salary was $10,560
Step-by-step explanation:
Answer: x = $30,560
Step-by-step explanation:
1. Let the second month payment be x
2. The first month + The second month = both of the months
3. So substituting: 10,205 + x = 40,765
4. Subtract 10,205 from both sides: x = 30,560

find the area of the fragment if each square on the grid represents 1cm2.
PLEASEEEEE HELPPPPP!!!!!!
The area of the fragment is \(10cm^{2}\) if each square on the grid has the area of \(1cm^{2}\).
We have been given the area of one square on the grid is \(1cm^{2}\).
We have to find the total area of the fragment.
Let's calculate the total area of the fragment.
We have been given the area of one square in the fragment is \(1cm^{2}\) .
Step 1: Count the number of squares present in the fragment.
Adding the number of colored squares in the row,
= 4 + 3 + 2 + 1
= 7 + 3
= 10
Step 2: Multiplying the number of squares in a fragment by the area of one square.
Now, forming an expression to calculate the total area,
= Number of squares X Area of one square
Substituting the values,
= \(10(1cm^{2} )\)
= \(10cm^{2}\)
Therefore, the area of the fragment is \(10cm^{2}\)

https://brainly.com/question/28470545
Correct question: Find the area of the fragment, if each square on the grid has an area of \(1cm^{2}\).
The area of the fragment is approximately 10 cm².
Hence, option D is correct.
Use the concept of the triangle defined as:
A triangle is a three-sided polygon, which has three vertices and three angles which has a sum of 180 degrees.
Gieven that,
Eeach grid has area = 1 cm²
Since each grid is of square shape,
Therefore,
Heigh of each grid = 1 cm
And the width of each grid = 1 cm
Now from the figure,
The height of the triangle = 4 cm
The width of the triangle ≈ 5 cm
Since knowing that,
Area of triangle = (1/2) x base x height
Therefore,
Area of the shaded region ≈ (1/2)x4x5
Area of the shaded region ≈ 10 cm²
Hence,
The area of the fragment is approximately 10 cm² which is option D.

A store regularly sells a Nintendo Switch Lite for $200. They are currently on sale for 30% off and in your state the sales tax is 8%. What would be the final cost for the consumer (including tax) if they buy the Nintendo Switch Lite?
Answer:
$151.20
Step-by-step explanation:
The sale price of the Nintendo Switch Lite is 30% off its regular price of $200, which means the discount is:
Discount = 30% x $200 = $60
The sale price of the Nintendo Switch Lite after the discount is:
Sale price = $200 - $60 = $140
The sales tax in the state is 8%, so the tax amount on the sale price is:
Tax amount = 8% x $140 = $11.20
Therefore, the final cost for the consumer, including tax, would be:
Final cost = Sale price + Tax amount = $140 + $11.20 = $151.20
Hence, the final cost for the consumer, including tax, would be $151.20 if they buy the Nintendo Switch Lite.

A theater has 500 seats. Three fourths of the seats are filled. How many seats are filled?
Answer:
375 seats are filled.
Step-by-step explanation:
The first step is to convert three fourths into a decimal.
In order to do so, I need to divide the numerator and the denominator.
3 ÷ 4 = 0.75
Now we need to multiply 0.75 by 500 beacause 0.75 were the number of seats filled and 500 was the number of seats.
0.75 x 500 = 375
So 375 seats are filled.

8th/9th-95 POINTS+BRAINLIEST!!!!!!!! How do you write a quadratic equation in vertex form? Please explain the steps in simple language and use y=x²+6x+16 as an example.
Answer:
In vertex form: y = 1(x - (-3))² + 7
Vertex: Minimum (-3, 7)
Explanation:
Vertex form: y = a(x - h)² + k
Completing square (rules) :
1st rule: (x + d)² = x² + 2dx + d² and (x - d)² = x² - 2dx + d²
2nd rule: x² + 2dx = (x + d)² - d² and x² - 2dx = (x - d)² - d²
Given equation:
y = x² + 6x + 16
y = x² + 2(3)x + 3² + 7
y = (x + 3)² + 7
Into vertex form:
y = 1(x - (-3))² + 7
From this identify:
a = 1, h = -3, k = 7
Solution, vertex of this equation: Minimum (-3, 7)

Answer:
25
Step-by-step explanation:
\(105+3x=180 \\ \\ 3x=75 \\ \\ x=25\)
Answer:
The answer is 25 degrees
Step-by-step explanation:
If you subtract 180 - 105 then you get 75.
Then you divide it by 3.
One circle is 360 degrees thus half of it is 180.
If you know one angle is 105 degrees then subtract it from 180.
If the number is 3x then you have to divide it by 3 to get x alone.

Brainlist for positive attitude and correct answer :D
Answer: The correct answer is:
Probability of rolling a number less than 3: 2/6 or 1/3
Step-by-step explanation:
Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.
Probability of not rolling a number less than 3: 4/6 or 2/3.
Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D

Seki, a professional bike racer, takes out a loan to buy her first high-end bike. The bike costs $seven thousand, five hundred, and the simple interest loan is for thirty months. She calculates that she will end up paying $seven hundred fifty in interest over the life of the loan.
.
What is the interest rate on Seki's loan?
The following sentence or sentences contain missing information in the form of one or more blanks. For each blank, there will exist a corresponding input field. Use the input fields to complete the sentence or sentences.
Interest Rate =
%
What is the total amount Seki will pay when the loan is due?
Balance = $
Answer: Seki's interest rate for the bike is 33.33% each year; Seki will owe $8250 at the end of the loan.
Step-by-step explanation:
To calculate the simple interest rate, the equation is: r = (1/t)(A/P - 1)
Where:
r - interest rate per year (in decimal format)
t -time (loan time in years)
A - total accrued amount (initial price paid + amount of interest paid)
P - principle (initial price paid)
For this scenario:
r = (1 / 30)(8250 / 7500 - 1)
- simplify both sets of parentheses: 1 / 30 and 8250 / 7500
r = (.033333)(1.1 - 1)
- simplify the second set of parentheses
r = (0.033333) x 0.1
- multiply
r = 0.0033333
- convert r (as a decimal) to R (as a percentage) by multiplying r x 100
R = .3333
The interest rate on Seki's loan is 33.33%
The total amount Seki will pay:
equation for total due: A = P + I
Where:
A - total accrued amount (initial price paid + amount of interest paid)
P - principle (initial price paid)
I - amount paid in interest that accrued over time
For this scenario:
A = 7500 + 750
A = 8250
Seki will pay $8250 when the loan is due.

Answer: It would be Second leg = 15
Step-by-step explanation:
From my understanding, you are supposed to find the second leg of the right triangle by Pythagoras theorem.
Hypotenuse: 25
One leg: 20
Second leg: x
Pythagoras theorem: hypotenuse² = adjacent² + opposite²
c² = a² + b²
25² = 20² + b²
b² = 25² - 20²
b² = 625 - 400
b² = 225
b = √225
b = 15
Therefore, the second leg of the right triangle is 15.
