Answer:
$7.2 A.t a wholesale
Step-by-step explanation:
80%of $36
The mathematical order is :
80÷100×36
80÷100×36=$28.8
When we have found the 80% that is added
We subtract it from the retail price.
$36-$28=$7.2
At the end we are left with our wholesale prices.

Determine if a quadrilateral with the given vertices is an isosceles trapezoid. Show and explain all steps to prove or disprove.
A(-5,0) B(5,0) C(-3, 4) D(3, 4)
By satisfying all the four criteria, the quadrilateral with the vertices A(x, y) = (-5, 0), B(x, y) = (5, 0), C(x, y) = (-3, 4) and D(x, y) = (3, 4) is an isosceles trapezoid.
How to determine if a quadrilateral is an isosceles trapezoidBased on vectorial expressions, an isosceles trapezoid satisfies the following properties:
(i) [tex]\overrightarrow{CD} = k \cdot \overrightarrow{AB}[/tex], for k ∈ [tex]\mathbb{R}[/tex]
(ii) AB ≠ CD
(iii) [tex]\overrightarrow{AC} \neq \overrightarrow {BD}[/tex]
(iv) AC = BD
Now we proceed to prove each property:
Requisite I
(3 - (-3), 4 - 4) = (6, 0)
(5 - (-5), 0 - 0) = (10, 0)
(6, 0) = (5/3) · (10, 0)
Requisite II
AB = 6, CD = 10
AB ≠ CD
Requisite III
[tex]\overrightarrow{AC} = (2, 4)[/tex]
[tex]\overrightarrow{BD} = (-2, 4)[/tex]
[tex]\overrightarrow{AC} \neq \overrightarrow {BD}[/tex]
Requisite IV
[tex]AC = \sqrt{[-3-(-5)]^{2}+(4-0)^{2}}[/tex]
[tex]AC = \sqrt{2^{2}+4^{2}}[/tex]
[tex]AC = 2\sqrt{5}[/tex]
[tex]BD = \sqrt{(3-5)^{2}+(4-0)^{2}}[/tex]
[tex]BD = \sqrt{(-2)^{2}+4^{2}}[/tex]
[tex]BD = 2\sqrt{5}[/tex]
AC = BD
The figure with the entire quadrilateral is shown below. Therefore, the quadrilateral with the vertices A(x, y) = (-5, 0), B(x, y) = (5, 0), C(x, y) = (-3, 4) and D(x, y) = (3, 4) is an isosceles trapezoid.

Answer: It would be 170
Step-by-step explanation:
5 x 10 + 5 x 10 + 5 x 10 = 150 but since it is park of the rectangle and not the triangle you don't multiply by 1/2 but the triangle part 4 x 5 you do 4 x 5 x 1/2 with is ten then you do it for the other side 4 x 5 x 1/2 equals ten. So 150 + 10 + 10=170

Question 5 (1 point) 5 The Cool Shirts company prints personalized designs on T-shirts. The cost y for x shirts with the same design is shown in the table below. y 10 $105 20 $185 30 $265 4:0 $345 Which equation represents the relationship between x and yo! A y = 10x - 55 By = 80x + 105 C y = 8x + 25 D y = 25x + 8 a А B od
Answer:
y = 8x + 25
Step-by-step explanation:
Using the coordinates (10, 105) and (20, 185)
The standard linear equation is expressed as y = mx+c
m is the slope
c is the intercept
m = 185 - 105/20-10
m = 80/10
m = 8
Get the y-intercept
Since y = mx+c
105 = 8(10) + c
105 = 80 + c
c = 105 - 80
c = 25
Get the required equation
Recall that y = mx+c
y = 8x + 25
Hence the required equation is y = 8x + 25

E, put 10 white chips and fiber chips in a bag draw a chip from the bag record its results and put it back in the bag do the seven times and count the total number of white chips drawn
Answer:
C and D
Step-by-step explanation:
Both have a 2/3 chance of success, and are completed 7 times :)
let me know if you need more explanation
Options (C) and (D) are same as Diego predictions.
What is probability?Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,
Diego predicts that his basketball team has two third probability of winning each of their next seven games.
The probability of winning = [tex]\frac{2}{3}[/tex]
We need to choose from the option, which has the same probability as above.
Option A:
Put the number 0 through 7 in a bag pick a number from the back.
Here, the probability = [tex]\frac{1}{8}[/tex] and the process is done for one time only.
So, this option is not same as above.
Option B:
Will a standard number cube 7 times count the number of twos.
Here, the probability = [tex]\frac{1}{6}[/tex]
So, the option is not same as above.
Option C:
Roll a standard number cube 7 times count how many of ones to threes and fours.
Here, the probability = [tex]\frac{4}{6}[/tex]
⇒ [tex]\frac{2}{3}[/tex]
So the option is same as above.
Option D:
Marcus spinner with 12 equally sized sections right when on four of the sections spin the spinner seven times and count the number of times it ends on the win.
Here, the probability = [tex]\frac{8}{12}[/tex]
⇒ [tex]\frac{2}{3}[/tex]
So the option is same as above.
Option E:
Put 10 white chips and fiber chips in a bag draw a chip from the bag record its results and put it back in the bag do the seven times and count the total number of white chips drawn.
Here, number of fiber chips is not given.
So, we could not predict the probability for this option.
Hence we can conclude that options (C) and (D) are same as Diego predictions.

Each side and each area were calculated using the Pythagoras theorem.
What is the Pythagoras theorem?The Pythagoras theorem states that, in a right triangle, the sum of squares of shorter sides is equal to the square of the hypotenuse.
So, using the Pythagoras theorem
[tex]TU^2=175^2-79^2[/tex]
[tex]TU^2=24384[/tex]
[tex]TU=156.15[/tex]
So, the corresponding area of the rectangle = 156.15*79 =12335.85 square units.
Similarly, [tex]GH = \sqrt{207^{2}-98^2 }[/tex]
[tex]GH=182.33[/tex]
So, the corresponding area of the triangle = 0.5*182.33*98 = 8934.27 square units.
Thus, each side and each area were calculated using the Pythagoras theorem.

100 POINTS PLS ANSWER
Answer:
x = 1, y = 3
Step-by-step explanation:
Given:
x - y = -2
2x + y = 5
First, add y on both sides for the first equation.
x = y - 2
Then, plug in x into the second equation.
2(y -2) + y = 5
2y - 4 + y = 5
3y = 9
y = 3.
Next, now that you've found y, plug it into either the first or second equation to solve for x. I'll be using the second equation.
2x + 3 = 5
2x = 2
x = 1.
Ans: x = 1, y = 3
