Answer:
The percentage is 0.008%
Step-by-step explanation:
The number of songs purchased each day from an online music store is 0.8% greater than the number purchased the previous day.
The original number of songs purchased from the online music store on the first day was 300,000. The number of songs purchased on any given day x is represented by the expression 300,000 ([tex]1.008^n[/tex]), where n is the number of days after the first day. To find the percent increase each day, you examine the multiplicative factor 1.008. This reflects a 0.8% (or 0.008 in decimal form) increase in the number of songs purchased from one day to the next. Therefore, each day the number of songs purchased is 0.8% greater than the previous day.

An RV leaving Canada is stopped at customs at the border and weighed. The scale shows a reading of 2.5 tons. What is the weight of the RV in tonnes?
The weight of the RV in tonnes is approximately 2.26796 tonnes.
Explanation:The weight of the RV can be converted from tons to tonnes using a conversion factor. One ton is equal to 0.90718474 tonnes. To find the weight of the RV in tonnes, we can multiply 2.5 tons by the conversion factor:
Weight in tonnes = 2.5 tons x 0.90718474 tonnes/ton = 2.26796 tonnes
Therefore, the weight of the RV in tonnes is approximately 2.26796 tonnes.

WILL MARK BRAINLIEST! PLEASE HELP MEH!Use the relationship between the angles in the figure to answer the question. Which equation can be used to find the value of x? Drag and drop the equation into the box.
A) x=180−31+40
B)x=90−40
C)x=180−(31+40)
D)x=90−(31+40)
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.

In the figure, PQ is parallel to RS. The length of RP is 2 cm; the length of PT is 18 cm; the length of QT is 27 cm. What is the length of SQ?
Step 1
Find the value of TS
we know that
if PQ is parallel to RS. then triangles TRS and TPQ are similar
so
[tex]\frac{TR}{TP} =\frac{TS}{QT}[/tex]
solve for TS
[tex]TS =\frac{TR*QT}{TP}[/tex]
we have
[tex]RP=2\ cm\\TP=18\ cm\\QT=27\ cm[/tex]
[tex]TR=TP+RP\\TR=18+2=20\ cm[/tex]
substitute
[tex]TS =\frac{20*27}{18}[/tex]
[tex]TS =30\ cm[/tex]
Step 2
Find the value of SQ
we know that
[tex]SQ=TS-QT[/tex]
we have
[tex]TS =30\ cm[/tex]
[tex]QT=27\ cm[/tex]
substitute
[tex]SQ=30\ cm-27\ cm=3\ cm[/tex]
therefore
the answer is
the value of SQ is [tex]3\ cm[/tex]

Why is the library not adding any more fairy tales
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.

Given a circle with measures of (C, d, and r) and a circle with measures of (C', d', and r'), what is r if C C' = 5 and d' = 20?
Answer:
r = 50Step-by-step explanation:
We know that:
[tex]\frac{C}{C'}=5[/tex][tex]d'=20[/tex]So, the ratio between the circumferences is 4 and the diameter of the second circle is 20. In this case, we have to use the ratio between those two circumferences, because that's what is our given data.
[tex]\frac{C}{C'}=\frac{d}{d'}\\5=\frac{d}{20}\\ 100=d[/tex]
From this proportion, we deduct that the diameter of the initial circle is 100. Now, we know that the radius in a circumference is have the diameter. Therefore, the radius is:
[tex]r=\frac{d}{2}=\frac{100}{2}=50[/tex]

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.
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.
Dilate (9, 6) using a scale factor of 1/3
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).
triangle ABC undergoes a series of transformations to result in Triangle DF is triangle DEF congruent to triangle ABC
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.
