Mr. Walker needs to purchase another pair of Crocs. He got an email coupon for 20% off an de free shipping at Shoebye.com. The pair he regularly $49.00 at Shoebuy. He also sees the same shoes on sale at Crocs.com for $35.00 plus $4.30 shipping and handling. Which is the better buy? Show your work to prove your answer.
Answer: Shoebuy.com
Step-by-step explanation:
20% of $49.00 is $9.8. When you subtract $9.80 from $49, you end up with $39.2. Now to look at Crocs.com, in order to get the total, add the price of the shoes, $35 and the shipping cost, $4.30, you'll end up with $39.30. Because Shoebuy is $.10 less than Crocs.com, it is the better choice.
After calculating the total costs, purchasing the Crocs from Shoebye.com with the 20% discount and free shipping comes out to be cheaper by $0.10 than buying them on sale at Crocs.com with added shipping and handling.
Explanation:Mr. Walker is trying to determine the better buy for a new pair of Crocs. The comparison involves a 20% discount and free shipping at Shoebye.com versus sale price with additional shipping and handling at Crocs.com.
Calculation at Shoebye.com:
Original price: $49.00
Discount (20% of $49): $9.80
Discounted price: $49 - $9.80 = $39.20
Shipping: $0 (free)
Total cost at Shoebye.com: $39.20
Calculation at Crocs.com:
Sale price: $35.00
Shipping and handling: $4.30Total cost at Crocs.com: $35.00 + $4.30 = $39.30
Comparing both totals, Shoebye.com's offer of $39.20 is slightly better than Crocs.com's offer of $39.30. Thus, purchasing from Shoebye.com would save Mr. Walker $0.10.

Describe the end behavior of the following function:F(x)=2x^4+x^3
A.The graph of the function starts low and ends high.
B.The graph of the function starts high and ends high.
C.The graph of the function starts low and ends low.
D.The graph of the function starts high and ends low.
The graph of the function starts high and ends high.
Answer: Option B.
Explanation:
The end conduct of a graph is characterized as what is happening at the parts of the bargains. As the capacity approaches positive or negative infinity, the main term figures out what the diagram resembles as it moves towards vastness.
The end conduct of a chart is the way our capacity carries on for extremely huge and tiny info esteems. For exponential capacities, we see that our end conduct goes to endlessness as our information esteems get bigger. The bigger the base of our exponential capacity, the quicker the development.
The end behavior of the function F(x) = 2x^4 + x^3 is determined by the term 2x^4. As x tends toward both positive and negative infinity, this term causes the function to increase towards infinity, meaning the graph starts low and ends high.
The question asks about the end behavior of the polynomial function F(x) = 2x^4 + x^3. To determine this, we look at the highest degree term, which dominates the end behavior. In this case, that term is 2x^4.
As x approaches positive infinity, 2x^4 will grow very large, so the function will also go towards infinity. Similarly, as x approaches negative infinity, 2x^4 will still grow very large (since an even power of a negative number is positive), and the function will go towards infinity as well. Thus, the graph of the function starts low when x is very negative and ends high as x becomes very positive.
Therefore, the correct answer to the student's question is Option A: The graph of the function starts low and ends high.

$2,200 deposit earning 4.2% compounded monthly, after 1 year
Answer:
2294.20
Step-by-step explanation:
the formula [tex]A = P (1+\frac{r}{n}) ^{nt}[/tex] will show the exponential growth in the account
A = amount in account (how much you'll have after earning interest)
P = the initial amount (how much YOU put in the account)
r = interest rate (in decimal form)
n = the number of times the interests in compounded in one year
t = number of years
plug in numbers into formula
(4.2 will become 0.042 because we need it as a decimal)
(n = 12 because monthly means every month and there is 12 months in a year)
formula will look like [tex]A = 2200 (1+\frac{0.042}{12})^{12(1)}[/tex]
once solved you will get 2294.199616 *round as needed

Bela started studying how the number of branches on her tree grows over time. Every 2.9 years, the number of
branches increases by an additional 83%, and can be modeled by a function, which depends on the amount
of time, t (in years).
When Bela began the study, her tree had 60 branches.
Write a function that models the number of branches t years since Bela began studying her tree.
Answer:
The required function that models the number of branches t years since Bela began studying her tree is
number of branches = [tex]60(1.83)^{\frac{t}{2.9} }[/tex]
Step-by-step explanation:
Let t be the time in years
Initially Bela's tree had 60 branches.
therefore the function that can be used to model the number of branches after t years will be given by
number of branches( after t years) [tex]= 60\times(1 + \frac{83}{100})^{\frac{t}{2.9} } = 60(1.83)^{\frac{t}{2.9} }[/tex]
The function model is [tex]B(t) = 60 * (1.83)^{\frac{t}{2.9}}[/tex].
To model the growth of branches on Bela's tree over time, we can use an exponential growth function. Given that the number of branches increases by 83% every 2.9 years, and the initial number of branches is 60, the function can be derived as follows:
The growth factor after each period of 2.9 years can be expressed as 1 + 0.83 = 1.83. If we let t represent the time in years, we need to determine how many 2.9-year periods have passed. This is given by [tex]\frac{t}{2.9}[/tex].
Thus, the function modeling the number of branches, B(t), after t years is:
[tex]B(t) = 60 * (1.83)^{\frac{t}{2.9}}[/tex]
This function accounts for the exponential growth of the number of branches on Bela's tree over time.

To find the length of LK, we can use the triangle similarity concept. First, let's compare triangles LJK and LMK. We can see that they share angle L, and we know that LJ = 10 and KM = 7. By comparing the corresponding sides, we can set up the proportion: LK / LJ = KM / KJ Substituting the given values, we have: LK / 10 = 7 / 11 To solve for LK, we can cross multiply and then divide: LK * 11 = 10 * 7 LK * 11 = 70 LK = 70 / 11 So, LK = 6.36 (rounded to two decimal places). Therefore, the answer is not provided in the answer choices.
From the answer choices, we can conclude that LK = d. 70/11.
What is the value?From the figure we are given, we can use the property of corresponding angles to determine the probable value of LK. From the corresponding sides, LK/LJ is equal to KM/KJ. Now, we substitute the given values to have the following:
LK / 10 = 7 / 11
To get the exact value of LK, we cross-multiply as follows:
LK * 11 = 10 * 7
LK * 11 = 70
LK = 70 / 11
So, the value of LK = 70/11.

one night a theater sold 548 movie tickets. an adult’s costs $6.50 an child’s cost $3.50. in all, $2,881 was takin in. how many of each kind of tickets were sold?
Answer:
321 adult tickets227 child ticketsStep-by-step explanation:
This sort of problem is easily solved by defining a variable to be the quantity of the higher-value contributor. Here, we can let x represent the number of adult tickets. Then total revenue is ...
6.50x +3.50(548-x) = 2881
3x +1918 = 2881 . . . . . . . . . . . . eliminate parentheses, collect terms
3x = 963 . . . . . . . . . . . . . . . . . . subtract 1918
x = 321 . . . . . . . . . . . . . . . . . . . . divide by 3
548-x = 548 -321 = 227 . . . . . .number of child tickets
321 adult tickets and 227 child tickets were sold.
By setting up and solving a system of equations, it was determined that the theater sold 320 adult tickets and 228 child tickets.
Let's denote the number of adult tickets as A and the number of child tickets as C.
The first piece of information given is:
Total tickets sold: A + C = 548
The second piece of information is related to the total revenue:
Total revenue from tickets: 6.50A + 3.50C = 2881
To find the values of A and C, we can use the substitution or elimination method to solve this system of equations. Here, we'll use the elimination method:
Multiply the first equation by 3.50 to align the coefficients of C with the second equation:
Subtract this new equation from the second equation to eliminate C:
Substitute A = 320 into the first equation to solve for C:
Therefore, the theater sold 320 adult tickets and 228 child tickets.
Find the length of the missing side of the triangle below
PLEASE HELPP!!
To find the length of the missing side, you can use the Pythagorean Theorem, which you can only use for right triangles.
Pythagorean Theorem: a² + b² = c²
[ c is the hypotenuse or the longest side of the triangle, and a and b are the other sides, I think it doesn't matter which side ]
Plug in what you know:
b = 8
c = 14
a² + b² = c²
a² + (8)² = (14)²
a² + 64 = 196 Subtract 64 on both sides
a² = 132 Square root both sides to get "a" by itself
[tex]\sqrt{a^2} =\sqrt{132}[/tex]
a = [tex]\sqrt{132}[/tex] inches
If you need to simplify more, you need to find two numbers that multiply to = 132 where one of them can be square rooted, to do so you can list the greatest common factors of 132
132: 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132
The only number that can be square rooted is 4, so you can do:
[tex]a=\sqrt{4*33}[/tex]
[tex]a=\sqrt{4} *\sqrt{33}[/tex]
[tex]a=2\sqrt{33}[/tex]

Triangle XYZ undergoes a single
transformation to form the image,
triangle X'Y'Z'. The image is congruent
to the original figure. Which of the
following best describes the possible
transformation that took place?
O A. a reflection only
O B. a rotation only
OC. a translation only
O D. a reflection, rotation, or a
translation
Answer:
D
Step-by-step explanation:
When something is forgoing a transformation that stays congruent, if it is rotating, it is simply turning a given amount of degrees: if it is translating, it is simply move up/down or right/left on the x and y axis; and finally, if it reflects, it is simply being inverted across either the x or y axis. None of these transformations result in changing the shape and/or size of the triangle.
Final answer:
The possible transformation that could have taken place is either a reflection, a rotation, or a translation, as they all preserve the congruency of the original triangle. Option D is correct.
Explanation:
If triangle XYZ is transformed to form triangle X'Y'Z' and the image is congruent to the original triangle, then the transformation could be a reflection, a rotation, or a translation. Congruent transformations are those that preserve the size and shape of a figure. Since the original triangle is congruent to its image after the transformation, we can conclude that the transformation is one that preserves congruency. Reflections across a line, rotations about a point, and translations (which slide a figure) all preserve the size and shape of the figure, and hence the triangles would remain congruent after any of these transformations.
The dimensions of a rectangular monitor screen are such that it’s length is 4 in. more than it’s width. If the length were doubled and if the width were decreased by 1 in., the area would be increased by 216 in^2. What are the length and width of the screen?
Answer:
14 inches by 18 inches
Step-by-step explanation:
Old rectangular monitor screen:
Width = x in
Length = x + 4 in
Area [tex]=x(x+4)\ in^2[/tex]
New rectangular monitor screen:
Width = x - 1 in
Length = 2(x + 4) in
Area [tex]=(x-1)(2(x+4))=2(x-1)(x+4)\ in^2[/tex]
This area would be increased by [tex]216\ in^2,[/tex] so the area would be equal to [tex]x(x+4)+216\ in^2[/tex]. Hence,
[tex]2(x-1)(x+4)=x(x+4)+216\\ \\2(x^2+4x-x-4)=x^2+4x+216\\ \\2x^2+6x-8-x^2-4x-216=0\\ \\x^2+2x-224=0\\ \\D=2^2-4\cdot (-224)=4+896=900\\ \\x_{1,2}=\dfrac{-2\pm \sqrt{900}}{2}=\dfrac{-2\pm 30}{2}=-16,\ 14[/tex]
The width cannot be negative, so
Width = 14 in
Length = 14 + 4 = 18 in

Step-by-step explanation:
f(x)=12x-29
Step 1, u bring the x terms over to one side, in this case on the left side. So it becomes:
f(x)-12x=29
Next step is to find the common factor of the x terms
f(x)-12(x)=29
f-12=29
bring the numbers to the right side
f=29+12
