An electronics retailer sells a washing machine at cost price (how much the retailer paid for it) of $400 with a profit of 20%. What price does the customer pay?
Answer:
$480
Step-by-step explanation:
They sold the machine for $400 but made a profit of 20%.
This mean you would take 400 × .20
This gives you 80
That means the retailer got an extra 20% or $80
for the washing machine.
$400 + $80 = $480
Sketch a figure that is similar to this figure. Label side and angle measures.
Step-by-step explanation:
Similar figures have different side lengths but corresponding angles are congruent.
The figure you sketch will have side length:
s = 12k, where k is the scale factorWhen k > 1, you sketch a larger figure, when 0 < k < 1, you sketch a smaller figure than pictured.
See attached, the two figures, one has side of 18 when k = 1.5, another one has side of 6, when k = 0.5

If a town with a population of 10000 doubles in size every 43 years, what will the population be 86 years from now
Answer:This is an exponential growth problem. If the population doubles periodically, it follows a law like this:
P(t) = P(0)ekt
where P(0) is the initial population at time t=0, and k is a constant with units of years-1.
To find k, let t=0. Then P(t) = P(0) = initial population = 5000.
Since the population doubles every 12 years, we can write
P(t+12) = 2P(t)
P(0)ek(t+12) = 2[P(0)ekt]
Simplifying,
e12k = 2
k = ln(2) / 12 = 0.0577623 years-1
Finally,
P(t) = 5000e0.0577623t, t in years
Then at t=48 years from now,
P(48) = 5000e(0.0577623 * 48) = 80,000

Find the slope of the line.
Answer:
1
Step-by-step explanation:
it can't be 2 because a slope is always in the mid or after a starting point I think..
Hello there! (:
To find the slope of this graph, we must calculate the rise over the run.
The rise is the amount of units we move up or down; the run is the amount of units we move right or left.
So here, we move 2 units up and 4 units to the right:
[tex]\frac{2}{4}[/tex]
We can reduce our fraction (divide the top and bottom by 2):
[tex]\frac{1}{2}[/tex]
Hope it helps! Please mark Brainliest; I would really appreciate that! (:

Answer:
c = 55
Step-by-step explanation:
I would solve this by cross multiplying, but some teachers don't appreciate you skipping a step like that. Instead:
[tex]\frac{5}{2} =\frac{c}{22}[/tex]
First, multiply both sides by 2:
[tex]5=\frac{2c}{22}[/tex]
Then, multiply both sides by 22:
[tex]2c=110[/tex]
Now, just solve for c by dividing both sides by 2:
[tex]c=55[/tex]
Answer:
C = 55
Step-by-step explanation:
To figure out c you must first isolate c so there shouldn't be any other numbers or signs (addition, subtraction, division, and multiplication) on the same side of the equal sign as variable C.
The inverse of dividing 22 is multiplying 22 on both sides of the equation.
You would get 22/1 * 5/2 = C. 22 * 5 is 110 and 1 * 2 is still 2 so 110/2 = C.
Enter 110/2 into the calculator and you would get C = 55
-3w+15w+7=8w+43 what does w equal?
Answer:
w = 9
Step-by-step explanation:
- 3w + 15w + 7 = 8w + 43 , simplifying
12w + 7 = 8w + 43 ( subtract 8w from both sides )
4w + 7 = 43 ( subtract 7 from both sides )
4w = 36 ( divide both sides by 4 )
w = 9
W=9
first, you simplify the expression.
12w + 7 = 8w + 43.
After that, we group all the w terms on the left side of the equation.
Subtract 8w from both sides:
12w + 7 - 8w = 8w + 43 - 8w
Group like terms:
12w - 8w + 7 = 8w + 43 - 8w
Simplify the arithmetic:
4w + 7 = 8w + 43 - 8w
Group like terms:
4w + 7 = 8w - 8w + 43
Simplify the arithmetic:
4w + 7 =43
Then, we group all constants on the right side of the equation
Subtract 7 from both sides:
4w + 7 - 7 = 43 - 7
Simplify the arithmetic:
4w = 43 - 7
4w = 36
Now, we isolate the w. Divide both sides by4:
4w / 4 = 36 / 4
Simplify the fraction:
w = 36/4
Find the greatest common factor of the numerator and denominator:
w = 9 × 4/1 × 4
Factor out and cancel the greatest common factor:
w = 9
given that any function of f(x)=x+a/x, where a and can be any value,will have the inverse of the form f^-1(x)=a/x-1
find the inverse of f(x)=x+4/x
please add your working
If f^(-1) is the inverse of f, then
f(f^(-1)(x)) = x
It looks like f(x) = (x + a)/x. This gives us
f(f^(-1)(x)) = (f^(-1)(x) + a)/f^(-1)(x) = x
Solve for f^(-1)(x) :
f^(-1)(x) + a = x f^(-1)(x)
f^(-1)(x) - x f^(-1)(x) = -a
(1 - x) f^(-1)(x) = -a
f^(-1)(x) = -a/(1 - x)
f^(-1)(x) = a/(x - 1)
If a = 4, then the inverse is f^(-1)(x) = 4/(x - 1).
The graph of F(x), shown below, resembles the graph of G(x) = x2, but it has
been changed somewhat. Which of the following could be the equation of
F(x)?
Answer:F(x)=-x2-3
Step-by-step explanation:We are given a function:
The graph of is also shown in the given question figure.
It is a parabola with vertex at (0,0).
Sign of is positive, that is why the parabola opens up.
General equation of parabola is given as:
Here, in G(x), a = 1
Vertex (h,k) is (0,0).
As seen from the question figure,
The graph of F(x) opens down that is why it will have:
Sign of as negative. i.e.
And vertex is at (0,-3)
Putting the values of a and vertex coordinates,
Hence, the equation of parabola will become:
The expression for [tex]f(x) = -(x-3)^{2}-2[/tex] represents the red curve.

Suppose that you could replace the ordered pair (1, 4) to make the relation R (shown left) into a function. Which ordered pair would work? (1, 2) (â€"1, 4) (2, 3) (4, 15).
We want to see which ordered pair we can add to the one we have in order to make R a function (sadly, we do not have the relation R, so expect a general answer).
Let's start by defining a function.
A function is a relation that maps elements from one set, the domain, into elements of another set, the range.
Where we also have a rule, each element in the domain can be mapped into only one element in the range.
So for example, if our relationship is:
R { (1, 2), (1, 3), (2, 4)}
The element of the domain "1" is being mapped into two different elements of the range, then this is not a function.
So, to answer the question, you would want to replace the element (1, 4) from one element that does not share the first value with any other of the relation.
Just to given an example, if the relation is:
R : { (1, 1), (1, 4), (2, 3), (3, 6)}
From the options, the only one that does not share the first element with any of the ordered pairs in R is (4, 15)
Then we replace (1, 4) by (4, 15)
And the relation becomes:
R' : {(1, 1), (2, 3), (3, 6), (4, 15)}
Which is a function.
