Answer: 23%
Step-by-step explanation:
From the question, we are informed that a new pair of shoes cost $78 and that they are on sale for $60.06.
The percent of change will be calculated as:
Change/ Cost price × 100
= [(78 - 60.06) / 78] × 100
= (17.94 / 78) × 100
= 0.23 × 100
= 23%

Brainliest plus 30 points could you help me with this its a Simplifying Radicals maze?https://drive.go ogle.com/file/d/1F4wd2VyL16D68UHnPVaZgye8niEV9Pe9/view
Okay, so it took me a few videos to understand what exactly we were supposed to be doing(your teacher wasn't exactly a ball of fire oop), but I pretty much get it now.
So basically the goal of simplification is to translate as much of the raticand as possible into whole numbers. Right now, most of the raticands are imperfect squares-- numbers whose square roots aren't whole numbers. If we ran these questions through a calculator, we'd get an answer like 17.88854382, which isn't super easy to manipulate.
Instead, we want to break that up into two parts-- the whole number and a much smaller radical. To do this, we need to find the largest factor of each raticand that's a perfect square, which is a number who has a square root of a whole number(for example 25, whose square root is 5).
For example, lets find the largest perfect square of the first problem: (I'm sure there's a better way to do this, but I just try dividing the number by 2, 3, 4, and so on until I find a perfect square)
[tex]320 \div 2 = 160( \sqrt{160} = 12.65)(imperfect) \\ 320 \div 3 = 106.67( \sqrt{106.67} = 10.32)(imperfect) \\ 320 \div 4 = 80( \sqrt{80} = 8.94)(imperfect) \\ 320 \div 5 = 64( \sqrt{64} = 8)(perfect)[/tex]
So now we know that
[tex] \sqrt{320} [/tex]
is the same as
[tex] \sqrt{64} \times \sqrt{5} [/tex]
Finally, we take the square root of 64(in this case 8) and append it to the front of the other radical, like so:
[tex]8 \sqrt{5} [/tex]
and there we go! We have successfully simplified the radical.
I want you to try this out now, and tell me if it makes sense. If it doesn't, tell Gem and I can try to clarify for you on zoom. Sorry for the delay buck, but I hope this is what you needed!

PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
a) 67
b) x= -8 and 4
c) 31
Step-by-step explanation:
a) if m<1 = (6x - 5) and m<5 = (5x+7), find m<3.
6x - 5 = 5x + 7
-5x + 5 - 5x + 5
x = 12
6(12) - 5 = 5(12) + 7
72 - 5 = 60 + 7
67 = 67
b) if m<4 = 32 and m<8 = (x^2 - 4x), find x.
32 = x^2 - 4x
- 32 - 32
x^2 - 4x - 32
(x - 8)(x + 4)
x - 8 = 0 x + 4 = 0
+ 8 + 8 - 4 - 4
x = -8 and 4
c) if m<4 = (4x - 17) and m<5 = (5x - 29), find m<1.
4x - 17 = 5x - 29
-5x + 17 -5x + 17
-x = -12
/-1 /-1
x = 12
4(12) - 17 = 5(12) - 29
48 - 17 = 60 - 29
31 = 31
The ___
is the variable that determines the value of the output in a function
Here, we are required to identify what is the variable that determines the value of the output in a function.
The Independent variable is the variable that determines the value of the output in a function.Most mathematical functions take the form;
y(x) = polynomial in terms of x.
such as; y = 5x + 6
In the scenario above; the connotation f(x) can simply be written in words as;
y being a function of x.Consequently, the value of x is the determinant of the corresponding value of y.
This means that y(output) is dependent on x(input) and as such;
This concept is evident in Regression Analysis.
The variable y can be termed the Dependent variable and the variable x can be termed the Independent variable.

For the equation y = 2.5X, choose which ordered pairs would be on the line if it was graphed? Select ALL that apply.
(0, 0) and (-4, -10)
(-1, -2.5)
(0. 0) and (2, 5)
(3, 7.5) and (-3, -7.5)
(1, 3.5) and (2, 5)
(1, 2.5) and (3, 6.5)
Answer:
(0, 0) and (-4, -10)
(0. 0) and (2, 5)
(3, 7.5) and (-3, -7.5)
Step-by-step explanation:
We have the function:
y = 2.5*x
This is a linear relationship, with a slope equal to 2.5 and y-intercept equal to zero.
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Then we can check with the points given in the options, and see which ones meet these two criteria.
a) (0, 0) and (-4, -10)
the slope will be:
a = (-10 - 0)/(-4 - 0) = 2.5
The slope is 2.5, then:
y = 2.5*x + b
To find the value of b, we just need to replace the values of one of the points in the equation, let's use the point (0, 0)
0 = 2.5*0 + b
0 = 0 + b
Then b = 0
y = 2.5*x
This means that these points would be on the line when graphed.
b) (0. 0) and (2, 5)
in this case the slope is:
a = (5 - 0)/(2 - 0) = 2.5
then:
y = 2.5*x + b
to find the value of b, let's use the point (0, 0)
0 = 2.5*0 + b
0 = 0 + b
b = 0
then
y = 2.5*x
This ordered pair would be on the line when graphed.
c) (3, 7.5) and (-3, -7.5)
The slope is:
a = (-7.5 - 7.5)/(-3 - 3) = 2.5
y = 2.5*x + b
The value of b will be obtained by using the point (3, 7.5)
7.5 = 2.5*3 + b
7.5 = 7.5 + b
b = 0
Then:
y = 2.5*x
This ordered pair will be on the line when graphed.
d) (1, 3.5) and (2, 5)
The slope is:
a = (5 - 3.5)/(2 - 1) = 1.5
The slope is different than 2.5, then we can discard this pair.
e) (1, 2.5) and (3, 6.5)
the slope is:
a = (6.5 - 2.5)/(3 - 1) = 2
Again, the slope is different than 2.5, then this option can be discarded.
We can conclude that the ordered pairs that will be graphed are:
(0, 0) and (-4, -10)
(0. 0) and (2, 5)
(3, 7.5) and (-3, -7.5)

Which choice would transform the rectangle to quadrant IV?
This shows a rectangle in the coordinate plane. А) rotate 180° clockwise about the origin +8 +7 +6 +5 B translate left 10 units +4 +2 © reflect over the y-axis +1 +2 +3 +4 +5 +6 +7 +8 1 reflect over the x-axis
Answer:
reflect over the x-axis
Step-by-step explanation:
Transformation is the movement of point from its initial location to a new location. Types of transformation is rotation, reflection, translation and dilation.
If a point A(x, y) is rotated 180° clockwise about the origin the new position would be A'(-x, -y)
If a point A(x, y) is reflected over the y-axis the new position would be A'(-x, y).
If a point A(x, y) is reflected over the x-axis the new position would be A'(x, -y)
If a point A(x, y) is translated a units left the new position would be A'(x-a, y).
The rectangle has points at (2, 2), (2, 5), (7,2), (7,5). If the rectangle is reflected over the x-axis the new position would be at (2, -2), (2, -5), (7, -2), (7, -5) which is at the fourth quadrant

The possibility of the unknown number which are less than 7 and greater than 3 could be 4, 5 and 6.
What are system of inequalities?When mathematical expressions are compared, with non-strict equality, then such mathematical statements are called mathematical inequalties.
A collection of inequalities for which we consider common solution for all inequalities is called a system of inequalities.
WE have been given that 'A number u is less than 7 and greater than 3.'
Let the unknown number be x then;
3 < x < 7
Therefore, the possibility of the unknown number which are less than 7 and greater than 3 could be 4, 5 and 6.
