An old-fashioned method of saving money is to stuff it in your mattress or hide it in a cookie jar on the top shelf of your closet. But most financial consultants will argue against this method of saving your money. Why? Give an example of a better solution to saving money that might be advised by a financial consultant.
Answers
Financial consultants argue against keeping cash at home and suggest opening a savings account or investing in a certificate of deposit (CD) for safer and more effective saving methods.
Explanation:Financial consultants argue against the old-fashioned method of saving money by stuffing it in a mattress or hiding it in a cookie jar because it is not a safe or effective way to save. Keeping cash in your home puts it at risk of theft or loss, and it does not provide any potential for growth or earning interest. Instead, a financial consultant may suggest opening a savings account at a bank or credit union. This allows your money to be securely stored and can also earn interest over time. Another option they may recommend is investing in a certificate of deposit (CD), which offers a higher interest rate but requires depositing the money for a specific period of time.

Factor the expression. d^2-14d+49
Answers
Procedure to factor:
The expression to factor is a trinomial.
Steps:
1) Probe whether this is a perfect square trinomial, i.e a trinomial that can be factored as (a + b)^2 or (a - b)^2.:
2) Determine if the first and the third terms of the trinomial (once it is ordered, which it is) have exact square roots:
√ (d^2) = d
√49 = 7
3) Since they have exact square roots, test wether the second term of the trinomial equals twice the product of the two square roots determined:
=> 2 * (d) * (7) = 14d which is exactly the second term of the trinomial
4) Now you can write the binomial squared using the sign of the second term. This is:
(d - 7)^2.
You can prove that that is the answer by expanding the binomial squared, which must drive back to the original expression: d^2 - 2(7)(d) + 7^2 = d^2 - 14d + 49.

Why is the library not adding any more fairy tales
Answers
Final answer:
The library may not be adding more fairy tales due to decreased demand, a desire to offer a diverse collection, and a strategic choice to provide a balanced collection.
Explanation:
It is possible that the library is not adding any more fairy tales due to a variety of reasons. One reason could be that the demand for fairy tales has decreased among library patrons. Another reason could be that the library wants to diversify its collection and offer a wider range of books to its readers.
Additionally, the library may be focusing on acquiring books from different genres or themes to cater to the interests of its diverse audience.
It is important to note that libraries regularly make decisions about which books to add to their collection based on factors such as popularity, relevance, and availability. The decision to not add any more fairy tales could simply be a strategic choice made by the library to provide a more balanced and comprehensive collection for its readers.

triangle ABC undergoes a series of transformations to result in Triangle DF is triangle DEF congruent to triangle ABC
Answers
Since, translation and rotation both are rigid transformations which maps only congruent images. They do not change the size and shape of pre-image.
Thus, here ΔABC is congruent to ΔDEF.
Triangle ABC is reflected over x axis ,and then translated 6 units down to form triangle DEF.Since, translation and reflection both are rigid transformations which maps only congruent images. They do not change the size and shape of pre-image.
Thus, here ΔABC is congruent to ΔDEF.
Triangle ABC is rotated 180°, and then dilated by a scale factor of 3 to form triangle DEF.Here rotation is a rigid transformation which maps only congruent images but dilation is not a rigid transformation because it produces similar images for scale factor other than 1 (with scale factor 1 it also produce congruent images) .
Thus, here ΔABC is not congruent to ΔDEF.
The determination of congruency between Triangle DEF and Triangle ABC depends on the nature of the transformations applied to Triangle ABC. If these transformations are rigid motions, then Triangle DEF will be congruent to Triangle ABC.
Explanation:The question concerns whether Triangle DEF is congruent to Triangle ABC after undergoing a series of transformations. Congruent triangles are those that are identical in terms of size and shape, meaning their corresponding sides and angles are equal.
According to the given information, to determine congruency, we must consider the properties of the transformations involved. If the transformations applied to Triangle ABC are rigid motions (such as rotation, reflection, or translation), which do not alter the shape or size of figures, then Triangle DEF will be congruent to Triangle ABC. If however, the transformations include dilation or other non-rigid transformations that change the size but not the shape, Triangle DEF would not be congruent, although it could be similar to Triangle ABC.
Since the question provided involves linear transformations that transform lines into lines and take parallel lines to parallel lines, it is likely referring to rigid motions. Therefore, it suggests that Triangle DEF should be congruent to Triangle ABC, assuming that the series of transformations includes only those that preserve lengths and angles.

C)x=180−(31+40)
D)x=90−(31+40)
Answers
to find x start with this equation
31 + x + 40 = 180 Now get all the numbers on the right.
(31 + 40) + x = 180
x = 180 - (31 + 40)
Only A or C can be correct. It is C, but you have to be very careful how you eliminate A
C <<<< answer.
x = 180 - 31 - 40 is the correct way to remove the brackets.
x = 180 - 71
x = 109
There are better ways to do this particular question without using brackets.
Answer:
C. [tex]x=180^o-(31^o+40^o)[/tex]
Step-by-step explanation:
We have been given a figure of angles formed on a straight line.
Since we know that the angles on a straight line add up-to 180 degrees. Upon using this property we can set an equation as:
[tex]31^o+x^o+40^o=180^o[/tex]
Let us subtract 40 and 31 degrees from both sides of our equation to solve to x.
[tex]31^o-31^o+x^o+40^o-40^o=180^o-31^o-40^o[/tex]
[tex]x=180^o-31^o-40^o[/tex]
Upon factoring negative sign from right side of our equation we will get,
[tex]x=180^o-(31^o+40^o)[/tex]
Therefore, the equation [tex]x=180^o-(31^o+40^o)[/tex] can be used to find the value of x and option C is the correct choice.

Dilate (9, 6) using a scale factor of 1/3
Answers
To get this answer we either...
A) Multiply both coordinates by 1/3
or
B) Divide each coordinate by 3
9*(1/3) = 9/3 = 3
6*(1/3) = 6/3 = 2
To dilate the point (9, 6) using a scale factor of 1/3, multiply the x-coordinate and y-coordinate by the scale factor to find the new coordinates which are (3, 2).
Explanation:To dilate the point (9, 6) using a scale factor of 1/3, we can multiply the x-coordinate and y-coordinate of the point by the scale factor to find the new coordinates.
For the x-coordinate, we have (9) * (1/3) = 3.
For the y-coordinate, we have (6) * (1/3) = 2.
So the dilated point is (3, 2).

Final answer:
About 52 dog owners would be expected to brush their dog's teeth.
Explanation:
The question is asking to estimate the number of dog owners who brush their dogs' teeth based on the given percentage from a study. To calculate this, you would take the total number of dog owners and multiply it by the percentage that brush their dogs' teeth. In this case, there are 578 dog owners and 9% of them are expected to brush their dogs' teeth.
Here is the calculation:
Number of dog owners who brush their dogs' teeth = Total number of dog owners × Percentage of owners who brush teethNumber of dog owners who brush their dogs' teeth = 578 × 0.09Number of dog owners who brush their dogs' teeth ≈ 52Therefore, about 52 dog owners out of 578 are expected to brush their dogs' teeth.
