Answer:
$578.33
Step-by-step explanation:
To get 5% of the original cost you need to multiply by 0.05
550.79 • 0.05 = 27.5395
27.5395 is 5% of 550.79
Since the price is marked up 5% you will need to add 27.5395 to 550.79
550.79 + 27.5395 = 578.3295
Then you will round your answer to 578.33
28. An Amazon Echo originally costs $99.99. It is on sale for 10% off. Sales tax of 7.5% is then added to the sale price. What is the cost of the Echo on sale including tax? Round your answer to the nearest penny.
Answer:
$96.74
Step-by-step explanation:
The original cost of the Amazon echo = $99.99
Then we have a 10% sale which we are going to subtract from the original cost.
= $99.99-(99.99x10%)
= 99.99-9.999
= $89.991
Then a tax of 7.5% was added
= $89.991 + (89.991 x 7.5%)
= 89.991 + 6.749325
= $96.740325
Therefore the cost of the echo including tax is $96.74

what is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Let w = the number of weeks.
Let d = the number of dollars April pays the service.
April pays a dog-walking service $30 each week to walk her dog.
So, the equation represents the situation
d= 30 x w
Hence, the amount in dollar for w weeks be d= 30 x w.

Write a decimal that the model represents
Answer:
number = 0.011
Step-by-step explanation:
Decimal Representation
The model is shown in the figure. It has a form of a cube where each face is divided into 10 equal squares, forming a 10x10x10=1,000 smaller cubes piece.
Out of that 1,000 cubes, only 11 are shaded. This leaves us to think the decimal represented by the model is the division between the shaded cubes by the total cubes, thus:
[tex]number= \frac{11}{1,000}[/tex]
Dividing:
number = 0.011

Which box plot represents the data
Answer:
Your answer would be D It makes much more sense than the others
Step-by-step explanation:
good luck :)
Answer:
First option at second row , Option( C )
Step-by-step explanation:
In order to solve the problem,
First we need to arrange the numbers in ascending order.
4 , 7 , 8 , 10 , 11 , 13 , 15 , 15 , 22 , 28
Median = [tex]\frac{11 + 13}{2}[/tex]
= 12
From the first range ( 4,7,8,10,11 ) , we can find Q1 also known as first quartile where Q1 = 8 ( middle-most number).
Similarly, from the second range ( 13,15,15,22,28 ) , we can find Q2 also known as third quartile where Q3 = 15 (middle-most number ).
Now, for the box plot,
We need to draw a number line from 0 to 32.
Next, we need to draw a box from Q1 to Q3 with a vertical line through the median.
Next, we put dots above 4 and 28 since our numbers start from 4 and end with 28.
Finally we join the dots and the box plot with a straight line.
Hence, option C is the correct choice.

Answer:
The function is increasing on the intervals (-∞, -1) and (2, ∞)
The function is decreasing on the intervals (-1, 2)
The domain of the function is (-∞, ∞)
Step-by-step explanation:
In order to see where the function is decreasing or increasing, check the x values to see where it is the rise and where it is fall. The domain of the function is never-ending so it is (-∞, ∞)
An object moves along a straight line so that at any time t , for 0≤t≤8 , its position is given by x(t)=5+4t−t2 . For what value of t is the object at rest?
A. t = 2
B. t = 4
C. t = 9/2
D. t = 5
Answer:
D. t = 5
when the object is at rest => x(t) = 0
<=> -t^2 + 4t + 5 = 0
<=> t^2 - 4t - 5 = 0
<=> (t - 5)(t + 1) = 0
=> t = 5 or t = -1
but t》0
=> t = 5
The value of t if the object at rest is 2 secs: Option A is correct
Given the position of the object moving in a straight line expressed as:
x(t)=5+4t−t²
The velocity of the body at rest is zero
Get the velocity fucntion.
v(t) = d(x(t))/dt = 4 - 2t
Since v(t) = 0
0 = 4 - 2t
-4 = -2t
t = 2
Hence the value of t if the object at rest is 2 secs

Let f(x)=x−1. The graph of g(x)=f(x)+k is shown below. Identify the value of k.
Explanation:
The linear equation f(x) = x-1 has the y intercept -1. We can see this by comparing it to y = mx+b and see that b = -1. Or we could plug in x = 0 to get the output y = -1.
The graph shows the y intercept is y = 3. The jump from y = -1 to y = 3 is plus 4. This means the graph of f(x) has been moved up 4 units. Therefore, k = 4.
Since y = f(x), saying g(x) = f(x)+k = f(x)+4 means we add 4 onto each y value. This indicates every point on the f(x) line moves up 4 units to arrive at a corresponding point on the g(x) line.
