Answer:
x = - \(\frac{2}{9}\)
Step-by-step explanation:
Given
\(\frac{2}{5}\) (x - 2) = 4x
Multiply both sides by 5 to clear the fraction
2(x - 2) = 20x ( divide both sides by 2 )
x - 2 = 10x ( subtract x from both sides )
- 2 = 9x ( divide both sides by 9 )
- \(\frac{2}{9}\) = x

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

Students record the number of minutes they read each day. The box plot shows the sumary of the results. Which statement best describes the data?
The correct statement is F: A quarter of the students read for 20-30 minutes.
What is the significant use of graphs in real life?Graphs are a not unusual place technique to visually illustrate relationships withinside the statistics. The reason for a graph is to provide statistics that are too severe or complex to be defined appropriately withinside the textual content and in much less space.
Looking at the box plot, we can see that the box represents the middle 50% of the data, with the bottom of the box indicating the 25th percentile and the top of the box indicating the 75th percentile. The line inside the box represents the median (50th percentile).
From the plot, we can see that the bottom of the box is at around 20 minutes and the top of the box is at around 45 minutes.
Therefore, the middle 50% of students read for times between 20 and 45 minutes. Since the median is around 30-35 minutes, we can infer that approximately a quarter of the students read for 20-30 minutes.
Therefore, statement F is the best description of the data based on the given box plot.

Are the triangles a. Similar b. congruent c. neither d. or both
Answer:
They are similar.
Step-by-step explanation:
Due to them only being 1cm off so they are similar.
Answer:
C
Step-by-step explanation:
Similar triangles are triangles that are equally proportional to each other. Although the side lengths only differ by one in the two triangles, they are not equally proportional. Below is an example of similar triangles:
Triangle 1 has side lengths of 5, 12, and 13.
Triangle 2 could have side lengths of 10, 24, and 26(multiply sides by 2), or it could have side lengths of 15, 36, and 39(multiply sides by 3).
Congruent triangles have congruent/equal side lengths along with angle degrees.
So, your answer is C
Write a story to represent the expression 6 divided by 3/4. Use multiplication to show the solution.
Answer: 6 divided by 3/4 is 8
Step-by-step explanation:
First when you divide 6 and 3/4. We use a dividing a fraction by a whole number. We have to make 3/4 into 4/3 to make it easier because we are trying to have a whole number. Then you multiply 6 and 4 to get 24 then you divide by 3 so you get 24/3. When you divide this, you get 8.
Once up a time there were 6 and there were 3/4. 6 was the big guy. 3/4 was the smallest in the hood. they were enemies. One day they had a fight and 6 was divided by 3/4 and became 0.5 or 1/2. now 3/4 was the big guy.

Answer: 23
Step-by-step explanation: This is because 68 divided by 4 is 17 plus 3 which is 20 and the two negatives make the other 3 positive so add three and you get 23.
Q- Write the nth term, generalized statement, and the 100th term of the given number sequence. (Need answer urgent!!....... WILL MARK AS BRAINLIEST!!)
1) 1,2,3......
2) 2,4,6.....
3) 3,5,7......
4) 1,4,7,10
5) -1,-2,-3
Answer:
1) n
2) 2n
3) 2n+1
4) 3n-2
5) -n
Step-by-step explanation:
To write a generalized statement for a pattern using n, we multiply n by the common difference between each term. We add the term number before the first term to this.
1) 1, 2, 3...
For the first question, the common difference is 1 because each term increases by 1. Multiply n by 1.
1n
To find the term number before the first term, we subtract 1 from the first term.
1-1=0
Therefore, our general statement is 1n+0, or just n.
2) 2, 4, 6...
The common difference is 2 because we add 2 each time. Multiply n by 2.
2n
The term number before the first term is equal to the first term - the common difference.
2-2=0
Therefore, our general statement is 2n+0, or just 2n.
3) 3, 5, 7...
The common difference is 2 because we add 2 each time. Multiply n by 2.
2n
The term number before the first term is equal to the first term - the common difference.
3-2=1
Therefore, our general statement is 2n+1.
4) 1, 4, 7, 10...
The common difference is 3 because we add 3 each time. Multiply n by 3.
3n
The term number before the first term is equal to the first term - the common difference.
1-3=-2
Therefore, our general statement is 3n+(-2), or 3n-2.
5) -1, -2, -3...
The common difference is -1 because we subtract 1 each time. Multiply n by -1.
-1n
The term number before the first term is equal to the first term - the common difference.
-1-(-1)
= -1+1 (because two negatives make a positive)
= 0
Therefore, our general statement is -1n+0, or just -n.
I hope this helps!

What is the correct expanded form and value of (One-fifth) Superscript 4?
One-fifth + one-fifth + one-fifth + one-fifth = StartFraction 4 Over 5 EndFraction
One-fifth times one-fifth times one-fifth times one-fifth = StartFraction 1 Over 625 EndFraction
StartFraction 1 + 1 + 1 + 1 Over 5 times 4 EndFraction = StartFraction 4 Over 20 EndFraction
One-fifth times 4 = StartFraction 4 Over 5 EndFraction
Answer:
One-fifth times one-fifth times one-fifth times one-fifth = StartFraction 1 Over 625 EndFraction
Step-by-step explanation:
1/5^4 = 1/5 * 1/5 * 1/5 *1/5 = 1/625
The expanded form of (One-fifth)⁴ is "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction," and its value is "StartFraction 1 Over 625 EndFraction."
The expanded form of (One-fifth)⁴ can be derived by multiplying (1/5) four times. Each multiplication represents multiplying by one-fifth, resulting in "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction." This can be further simplified as "StartFraction 1 Over 625 EndFraction" by multiplying the numerators and the denominators separately.
In mathematical terms, when we raise one-fifth to the power of 4, we are essentially multiplying one-fifth by itself four times. Thus, (One-fifth)⁴ is equal to "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction."
Evaluating this expression yields the value "StartFraction 1 Over 625 EndFraction" since multiplying the numerators (1 * 1 * 1 * 1) and the denominators (5 * 5 * 5 * 5) results in 1 and 625, respectively.
Mathematical representation: \(\frac{1}{5}^4= \frac{1}{5} * \frac{1}{5} * \frac{1}{5} * \frac{1}{5}\)

The constant of Proportionality is 8.
What is constant of Proportionality?If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.
Given:
Total Baseball Caps= 30
Total amount of Cap= $240
let the number of caps sold be c.
Then, the equation is
30 c= 240
and, c= 240/30
c= 8
Hence, the constant of Proportionality is 8.

The football team has a total of 25 jerseys. There are 15 medium-sized jerseys. What percent of the jerseys are medium-sized jerseys?
60 percent of the jerseys are medium-sized jerseys.
what is percent?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
total jersey= 25
15 are medium-sized jerseys.
Now, let the percent be x
So,
x% of 25= 15
x/100(25)= 15
x/4= 15
x= 60%
Hence, 60 percent of the jerseys are medium-sized jerseys.
