The function h(t) = 150 – 9t represents the height of a ball dropped from 150 feet after t seconds. What will the height of the ball be after 1.4 seconds?
Final answer:
The height of the ball after 1.4 seconds, using the function h(t) = 150 – 9t, is 137.4 feet above the ground.
Explanation:
To determine the height of the ball after 1.4 seconds using the function h(t) = 150 – 9t, we simply need to substitute the value of t with 1.4 seconds into the equation.
By plugging in the given values in the equation, the solution we get will be:
h(1.4) = 150 – 9(1.4) = 150 - 12.6 = 137.4 feet
Therefore, the height of the ball after 1.4 seconds will be 137.4 feet above the ground.
A set of cards contains cards numbered 1 – 8. Mrs. Jacob’s class is conducting an experiment in which a card is drawn from the pile, the number is recorded, and then the card is returned to the set. The class will conduct 1,000 trials. Based on the theoretical probability, which is the best prediction for the number of times a 4 will be drawn from the pile?
111
125
143
250
Answer:
2nd Option is correct.
Step-by-step explanation:
We are given a set of cards containing numbers from 1 to 8 on each cards.
Randomly a card is drawn and noted.
This is repeated 1000 times.
To find: Number of time 4 will be drawn from the pack using theoretical probability.
We know that,
Theoretical Probability: Probability which is based on reasoning and written as a ratio of the number of favorable outcomes to the total number of outcomes.
Probability of getting 4 from the pack = [tex]\frac{1}{8}[/tex]
Now, Number of the times 4 will be drawn from pack out of 1000 times
= [tex]\frac{1}{4}\times1000[/tex]
= 125
Therefore, 2nd Option is correct.

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.

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]

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.

D. contain fossils that resemble existing species more closely than do fossils found in older rock layers.
Rock layers that formed more recently contain fossils that resemble existing species more closely than do fossils found in older rock layers.
Explanation:Fossils found in rock layers provide evidence for Earth's long history of changing lifeforms. Rock layers that formed more recently contain fossils that resemble existing species more closely than do fossils found in older rock layers. This is because the more recent layers contain organisms that are more similar to the species that exist today.

Aphrodite traveled 144 leagues in 12 days. Then she doubled her rate. How long would it take her to travel 168 leagues at this new speed?
The first step in solving this problem is to compute for the original rate of Aphrodite.
144 leagues / 12 days = 12 leagues/day (original rate)
It was stated in the problem that she doubled her rate which she means she has a new rate of 24 leagues/day (12 x 2).
168 leagues / 24 leagues/day = 7
Therefore, it would take her 7 days to travel 168 leagues at her new speed.
