Answer:
The slopes of WX and XZ
Step-by-step explanation:
The singular factor that determines if the parallelogram is a rectangle are the angles at the edges
Mathematically, we can only have a rectangle if there are four right angles with one right angle each at the edges of the rectangle
So, by having the slope of the sides forming the width and that which forms the length, we can deduce if what we have is rectangle given that the slopes will yield a perpendicular product
Hence, the slopes of WX and XZ can be calculated to show this

❁ Question : Simplify :
[tex] \sf{( {x}^{a} ) ^{b - c} \times ( {x}^{b} ) ^{c - a} \times ( {x}^{c} )^{a - b}} [/tex]❁ Solution :
First , Use power law of indices.
Remember : If [tex] \sf{ {a}^{m} }[/tex] is an algebraic term , then
[tex] \sf{( {a}^{m} ) ^{n} } = {a}^{m \times n} = {a}^{mn} [/tex] , where m and n are positive integers.
➝ [tex] \sf{ {x}^{a(b - c)} \times {x}^{b(c - a)} \times {x}^{c(a - b)}} [/tex]
➝ [tex] \sf{ {x}^{ab - ac} \times {x}^{bc - ba} \times {x}^{ca - cb}} [/tex]
Now , Use product law of indices :
Remember : If [tex] \sf{ {a}^{m} }[/tex] and [tex] \sf{ {a}^{n}} [/tex] are the two algebraic terms , where m and n are the positive integers then [tex] \sf{ {a}^{m} \times {a}^{n} = {a}^{m + n}} [/tex]
➝ [tex] \sf{ {x}^{ab - ac + bc - ba + ca - cb}} [/tex]
Since two opposites adds up to zero , remove them :
➝ [tex] \sf{ {x} \: ^{ \cancel{ab} \: - \cancel{ac} \: + \cancel{bc} \: - \cancel{ba} \: + \cancel{ca} \: - \cancel{cb} } }[/tex]
➝ [tex] \sf{ {x}^{0} }[/tex]
Use Law of zero index
Remember : If [tex] \sf{ {a}^{0}} [/tex] is an algebraic term , where a ≠ 0 , then [tex] \sf{ {a}^{0} = 1}[/tex]
➝ [tex] \boxed{ \sf{1}}[/tex]

Madelyn has completed 10/20 problems. Will has completed 80% of the problems. Adam has finished 3/4 of them. Who has finished the most
Answer:
Will has completed the Most.
Step-by-step explanation:
Madelyn has completed 50%
Adam has completed 75%
Will has completed 80%
I hope this helps!!! Please Mark Me Brainliest!!!!!!
Answer: Will
Step-by-step explanation:
Madelyn = 50%. 10/20 = 50%, because 10/20 is half, and 50% is half
Will = 80%
Adam = 75%. 3/4 x 25 = 75/100, which equals 75%.
So in conclusion, Will has finished the most problems, 2nd is Adam, and last is Madelyn.
Hope this helps!
Eugene ate 20% of the Christmas cookies his
grandmother made. If he ate 8 cookies, how
many are left?
Answer:
There are 32 cookies left
Step-by-step explanation:
There are c cookies when we started
c* 20% = 8 cookies
Change to decimal form
c * .20 = 8
Divide each side by .2
c * .2 / .2 = 8/.2
c =40
There are 40 cookies when we started
40 -8 = 32
There are 32 cookies left

If Danny gains 40 yards on the football field and then looses 15, What was the end result?
Answer:
25 yards
Step-by-step explanation:
Subtract 15 from 40.
Hope this helped :)
Answer:
25 yards
Step-by-step explanation:
Arithmetics
Imagine a straight line divided into 1-yard marks.
Danny runs for 40 marks and locates at mark 40.
He later loses 15 yards and his new position is 40 - 15 = 25 yards
Therefore, the end result is that Danny is at the 25-yard mark.
a number c minus 4.3 is no less than 16. write this word sentence as an inequality.
ill give brainliest
Answer:
c - 4.3 > 16
(hope this helps)
The inequality representing a number c minus 4.3 is no less than 16 is c - 4.3 > 16.
What is inequality?The relationship between two values that are not equal is described by inequalities. Equal does not necessarily mean unequal. The "not equal symbol" is typically used to denote that two values are not equal.
As the condition is suggesting c - 4.3 is no less than 16 means it is greater than 16,
So, c - 4.3 > 16
Therefore, the inequality representing a number c minus 4.3 is no less than 16 is c - 4.3 > 16.

Rhombus JKLM with vertices J(-4,7), K(0,8), L(-1, 4), and M(-5,3): (x, y) ------> (x + 2, y - 2)
Answer:
J'(-2, 5), K'(2, 6), L'(1, 2) and M'(-3, 1)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation is reflection, rotation, dilation and translation.
Translation is the movement of a point either up, down, left or right on the coordinate plane. If a point A(x,y) is translated a units right and b units up, the new point is at A'(x + a, y + b) while a point A(x,y) is translated a units left and b units down, the new point is at A'(x - a, y - b).
Rhombus JKLM has vertices at J(-4,7), K(0,8), L(-1, 4), and M(-5,3). If a transformation of (x, y) ------> (x + 2, y - 2) is done, i.e. 2 units right and 2 units down, the new points would be at:
J'(-2, 5), K'(2, 6), L'(1, 2) and M'(-3, 1)

I am thinking of a number, let's call it x . If I increase twice my number by 5, the result is the same as if I triple my number and subtract 1. Use the 4-step process to write and solve an equation to find my number. Make sure to answer in a sentence.
Answer: 6
Step-by-step explanation:
Let the number be x
If I increase twice my number by 5, the result is the same as if I triple my number and subtract 1. This can be formed into an equation as:
(2 × x) + 5 = (3 × x) - 1
2x + 5 = 3x - 1
5 + 1 = 3x - 2x
x = 6
The number you are thinking of is 6
