Answer:
Yes, the sides are in the ratio 2:5.
Can you mark me as the brainliest??
Answer: The correct option is
(B) Yes, the sides are in the ratio 2:5.
Step-by-step explanation: We are given to check whether the triangles can be similar based on the side lengths alone.
From the figure, we note that
the sides lengths of the triangle RST are
RS = 3.0 cm, ST = 6.0 cm and RT = 6.4 cm.
and the corresponding side lengths of triangle XUW are
XU = 7.5 cm, UW = 15.0 cm and XW = 16.0 cm.
So, the ratio of the corresponding sides of the two triangles are as follows :
[tex]\dfrac{RS}{XU}=\dfrac{3}{7.5}=\dfrac{30}{75}=\dfrac{2}{5},\\\\\\\dfrac{ST}{UW}=\dfrac{6}{15}=\dfrac{2}{5},\\\\\\\dfrac{RT}{XW}=\dfrac{6.4}{16}=\dfrac{64}{160}=\dfrac{2}{5}.[/tex]
Therefore, we get
[tex]\dfrac{RS}{XU}=\dfrac{ST}{UW}=\dfrac{RT}{XW}=\dfrac{2}{5}=2:5.[/tex]
Hence, the corresponding sides are proportional and they are in the ratio 2 : 5.
Thus, (B) is the correct option.

Answer:
-9/2 , 3/2
Step-by-step explanation:
The coordinates of the midpoint of the line segment that has endpoints (-3,4) and (-6,-1) are (-4.5, 1.5).
What are the coordinates of the midpoint of the line segment AB?Suppose we've two endpoints of a line segment as A(p,q), and B(m,n), then let the midpoint be M(x,y) on that line segment. Then, its coordinates are x =(p+m)/2 and y = (q+n)/2.
Given the endpoints of the line segment are A(-3,4) and B(-6,-1), then the coordinates of the midpoint will be,
x = (-3-6)/2 = -9/2 = -4.5
y = (4-1)/2 = 3/2 = 1.5
Hence, the coordinates of the midpoint of the line segment that has endpoints (-3,4) and (-6,-1) are (-4.5, 1.5).

according to the rational root theron what are all the potential roots of f(x)=9x^4-2x^2-3x+4
Answer:
Potential roots: [tex]\frac{9}{4},\frac{9}{2},9,\frac{3}{4},\frac{3}{2},3, \frac{1}{4},\frac{1}{2},1[/tex]
Step-by-step explanation:
Simply put, the rational roots theorem tells us that if there are any rational roots of a polynomial function, they must be in the form
± [tex]\frac{FactorsOfa_{0}}{FactorsOfa_n}[/tex]
Where
a_n is the number before the highest power of the polynomial, and
a_0 is the constant in the polynomial
From the polynomial shown, we have a_n = 9 and a_0 = 4
The factors of 9 are 9, 3, 1
and
The factors of 4 are 4,2,1
So, if there are any rational roots, they would be:
± [tex]\frac{FactorsOfa_{0}}{FactorsOfa_n}[/tex]
± [tex]\frac{9,3,1}{4,2,1}[/tex]
Which is ± 9/4, 9/2, 9/1, 3/4, 3/2, 3/1, 1/4, 1/2, 1/1
or
[tex]\frac{9}{4},\frac{9}{2},9,\frac{3}{4},\frac{3}{2},3, \frac{1}{4},\frac{1}{2},1[/tex]
Using the Rational Root Theorem, the polynomial f(x) = 9x^4 - 2x^2 - 3x + 4 has potential rational roots which are ±4, ±2, ±1, and their counterparts divided by 3. In the complex number system, every nth-order polynomial can be factored into n roots, including imaginary roots for equations that lack real solutions.
Explanation:Rational Root Theorem and Potential Roots
The Rational Root Theorem is a useful tool for identifying all potential rational roots of a polynomial equation. When applying this theorem to the given polynomial f(x) = 9x^4 - 2x^2 - 3x + 4, we note that the potential rational roots are the divisors of the constant term (in this case, 4) divided by the divisors of the leading coefficient (in this case, 9). Therefore, the potential roots are ±4, ±2, ±1, and their counterparts divided by 3, which are ±4/3, ±2/3, and ±1/3. To determine which of these are actual roots, each must be tested in the polynomial equation.
The concept of complex number system further elaborates on polynomials by stating that every nth-order polynomial can have up to n roots, factored into linear factors in accordance with the fundamental theorem of algebra. In the case of second-order polynomials, the real number system may not yield roots for equations like x² + 1, but in the complex number system, such polynomials do have roots and can be factored as (x - i)(x + i), for instance.
At the end of each year, Carl and Linda Munson will deposit $2,100 into a 401k retirement account.
Find the amount they will have accumulated in 10 years if funds earn 8% per year.
Final answer:
To find the amount Carl and Linda Munson will have accumulated in 10 years, you can use the formula for compound interest. Plugging in the given values, their 401k retirement account will have approximately $3,639.48 after 10 years.
Explanation:
To find the amount Carl and Linda Munson will have accumulated in 10 years, we can use the formula for compound interest:
A = P(1+r)^n
Where:
A = amount accumulated after n years
P = principal amount
r = interest rate (in decimal form)
n = number of years
Using the given information, P = $2,100, r = 8% (or 0.08), and n = 10. Plugging these values into the formula:
A = $2,100(1+0.08)^10
Simplifying the expression:
A = $2,100(1.08)^10
Calculating the value:
A ≈ $3,639.48
Therefore, Carl and Linda Munson will have approximately $3,639.48 accumulated in their 401k retirement account after 10 years.

Step-by-step explanation:
The outlier is a point which lies differently or far away from rest points in datasets or distribution.
Here we can self-time for one apple on the 10th day is outlier present in the distribution. Thus Option (A) is correct.
We divide the heterogeneous group into many homogeneous groups, these homogeneous group is known as Cluster. It can be seen naturally.
Also, here distribution is divided into many clusters and we can see given distribution has many clusters and one of them is from 4 to 6 days. Thus Option (B) is also a correct option here.
here are my analyses of the possible answer choices based on the image you sent: The distribution clusters around 4-6 days and has a few potential outliers above 8 days.
here are my analyses of the possible answer choices based on the image you sent:
(A) The distribution has an outlier.
There are a few data points that are higher than the rest of the distribution, so in that sense, yes, there are outliers. However, it is important to consider what an outlier is in the context of the data. If the data is normally distributed, then outliers are data points that fall more than two standard deviations away from the mean. In this case, it is difficult to say for sure whether the data is normally distributed, so it is also difficult to say for sure whether there are outliers. However, there are a few data points that are higher than the rest of the distribution.
(B) The distribution has a cluster from 4 to 6 days.
There is a cluster of data points from 4 to 6 days, so yes, this statement is accurate.
In conclusion, the accurate descriptions of the distribution are:
The distribution has a cluster from 4 to 6 days.The distribution has a few outliers.How much fencing would he need?

two business partners, Ellen and Bob, invested money in their business at a ratio of 3 to 7. Bob invested the greater amount. the total amount invested was 200 dollars. how much did each partner invest?
Answer:
Ellen invested $60 and Bob invested $140
Step-by-step explanation:
let the two amounts invested by 3x and 7x
(notice 3x : 7x = 3 : 7 )
then 3x + 7x = 200
10x = 200
x = 20
then 3x = 3(20) = 60
and 7x = 7(20) = 140
60+140=200
Ellen invested $60, and Bob invested $140 in their business.
The student's question involves determining how much each business partner invested in their business based on a given ratio and total investment amount. Ellen and Bob invested money at a ratio of 3 to 7 with a total of $200 invested. To solve this, we need to find out what each 'part' of the ratio is worth in dollars.
Let's consider the total number of parts in the ratio, which is 3 (for Ellen) + 7 (for Bob) = 10 parts in total. Since the total amount invested is $200, each part of the ratio is worth $200 divided by 10, which is $20. Therefore:
Ellen invested 3 parts: 3 parts * $20 per part = $60.Bob invested 7 parts: 7 parts * $20 per part = $140.Hence, Ellen invested $60, and Bob invested $140 in their business.

Answer:
The number per hour = 5400 ÷ 8 = 675 action figures
Step-by-step explanation:
* Lets explain how to solve the problem
- A toy manufacturer uses 90 pints of plastic to make 600 action figures
- they use 810 pints of plastic in an 8 hour shift
- To find how many action figures are made per hour we must to find
how many action figures in an 8 hour shift and then find the number
of the action figures per hour
∵ The toy manufacture uses 90 pints of plastic to make 600 action
figures
∵ They use 810 pints
- Lets find how many action figures are made by this numbers of pints
∴ 90/600 = 810/x ⇒ x is the number of action figures
- Use the cross multiplication to find x
∴ 90 x = 810 × 600
∴ 90 x = 486000 ⇒ divide both sides by 90
∴ x = 5400
∴ They will use 810 pints to make 5400 action figures
∵ They use 810 pints in an 8 hour shift
∴ They make 5400 action figures in 8 hours
- To find the number of the action figures per hour divide the number
of them in 8 hours by 8
∴ The number per hour = 5400 ÷ 8 = 675 action figures
