You are searching online for the best price you can find for a hat that you really want to buy. The hat originally costs $20 at al three stores. Place the discounts in order of the best buy (at the top) to the worst buy (at the bottom). 1/5 off the price of the hat. 30% off the price of the hat. 5.00 off the hat
Answer:
Best to worst: 30% off, $5 off, 1/5 off. Need an explanation? See below for fully worked out answer!
Step-by-step explanation:
1/5 off of the hat:
1/5 of 20
20 divided by 5 equals 4
$4 would be taken off with this discount. 20-4=16. Therefore the hat would cost $16 at this store.
30% off of the hat:
20 times 30% = 20 times 0.30
20 times 0.30=6.
$6 dollars would be taken off of the hat. 20-6=14. Therefore, the hat at this store would cost $14.
$5 off of the hat.
20-5=15
The hat would cost $15 at this store.
Best to worst: 30% off, $5 off, 1/5 off.

x2 - 81 = 0
What is x2
Answer:
x = 9 and -9
Step-by-step explanation:
[tex]x^{2}[/tex] -81 = x add 81 to both sides of the equation
[tex]x^{2}[/tex] = 81 What number times itself equals 81? 9 and -9
Answer: + 9
Step-by-step explanation: add 81 to both sides to isolate x^2. we get x^2= 81. take the square root of both sides. the square root of x^2 is x and square root of 81 is 9 or -9. so x = 9 and -9.

3x + 2y =18
Y= -2/3x + 12
Answer:
3x + 2y =18
Y= -2/3x + 12
3x + 2(-2/3x+12) = 18
3x + (-4/3x+24) = 18
3x + -1 1/3x +24 =18
1 2/3x +24 = 18
1 2/3x = -6
5/3x = -6
x = -3.75
Step-by-step explanation:
3x = 18-2y
x= 6 - 2/3y
then substitute in the second equation
Y= -2/3x + 12
y=-2/3(6-2/3y)+12
y= 72/5
then substitute y= 72/5 in the first equation x= 6 - 2/3y
then x = -18/5

Solve 14−2x=28 using the replacement set {−21, −7, 7} .
A. −21
B. −7
C. 7
D. I don't know.
Answer:
B
Step-by-step explanation:
substitute the values from the replacement set into the left side of the equation to find which values of x make it true.
x = - 21
14 - 2(- 21) = 14 + 42 = 56 ≠ 28 ← False
x = - 7
14 - 2(- 7) = 14 + 14 = 28 ← True
x = 7
14 - 2(7) = 14 - 14 = 0 ≠ 28 ← False
Thus x = - 7 is the solution

the maximum walking speed S, in feet per second of an animal can be modeled by the equation S=the square root gL where g=32ft/sec and L is the length ,in feet, of the animal's leg.To the nearest hundredth how many greater is the maximum walking speed of giraffe with a leg length of 6 feet than a hipppotamus with a leg length of 3 feet.
The maximum walking speed of the Giraffe is 1.41 times greater than the maximum walking speed of the Hippopotamus
Calculating Maximum speedFrom the question, we are to determine how much greater the maximum walking speed of Giraffe is to that of Hippopotamus
From the give information,
The maximum walking speed, S, is given by
S = √gL
Where g = 32ft/sec
and L is the length of the animal's leg
Thus,
For a Giraffe with a leg length of 6 feet
S = √32×6
S = √192
S = 13.856 ft/sec
For a Hippopotamus with a leg length of 3 feet
S = √32×3
S = √96
S = 9.798 ft/sec
Now, we will determine how many times greater 13.856 is than 9.798
13.856/9.798 = 1.41
Hence, the maximum walking speed of the Giraffe is 1.41 times greater than the maximum walking speed of the Hippopotamus

Answer:
45mins
Step-by-step explanation:
The time required to produce 100 parts will be 10 minutes.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that a machine produces 4500 parts in an 8-hour day. The time will be calculated as below:-
4500 parts = 8 hours
100 parts = 8 / 45 hours
100 parts = ( 8 x 60 ) 45 minutes
100 parts = 10 minutes
Therefore, the time required to produce 100 parts will be 10 minutes.

♡ Answer ♡
12°
♡ Step-by-step explanation ♡
For this problem, we must find the value of x. In order to do this, there are a few simple steps we must follow.
However, before we begin, there is one important fact we should remember. As we know, there are 180 degrees in a triangle. This means that our total is 180°.
Our first step towards completing this problem is to subtract the amount of degrees we know from the total. In the picture, we can clearly tell that the degrees that are not attached to a variable are 27° and 9°. So, we can easily subtract those from 180°. 27° + 9° = 36°. 180°- 36° = 144°. This means that the remaining value we have left to work with, when incorporating that attached to x, is 144°.
The next step towards completing this question is to add the values of the numbers attached to x. In this case, the remaining values are 5x° and 7x°. The numbers attached to the variable x are 5 and 7. These are the two numbers we must combine to find the answer. 5 + 7 = 12. So, the total value of the numbers attached to x is 12.
This final step is directly connected to the last one. To find the value of x, we must divide 144° by 12. This is because the total degrees of the triangle that are directly connected to x are 144°, and the total values of the numbers directly attached to x are 12. Therefore, by dividing 144° by 12, the answer will be the value of x. 144° ÷ 12 = 12°. So, x is 12°.
Furthermore, there is actually a way to check to see that x is actually 12°. This strategy is by substituting x for 12°. To do this, I must multiply 5° by 12° (for 5x°) and 7° by 12° (for 7x). 5° * 12° equals 60°. 7° * 12° is 84°. 60° + 84° = 144°. Now, we must add the remaining values: 9° and 27°. 9° + 27° = 36°. 36° + 144° = 180°. If you remember, there are 180° in a triangle. 180° = 180°. This proves that the answer is indeed 12°

True Or False Questions
1. All Isoceles Triangles have at least two acute angles
2. If the perimeter of an equilateral triangle is P, then the length of each of the sides is P/3.
3. All isosceles triangles are equilateral triangles.
4. If you know the length of one of the legs of an isosceles triangle, you can determine it’s perimeter
5. The exterior angle of an equilateral triangle is obtuse
Answer:
Step-by-step explanation:
TRUE
All isosceles triangles have at least 2 acute angles due to 2 sides are equal.
The exterior angle of an equilateral triangle is obtuse.
If the perimeter of an equilateral triangle is P, then the length of each of the sides is P/3.
FALSE
All isosceles triangles are equilateral triangles.
If you know the length of one of the legs of an isosceles triangle, you can determine it’s the perimeter
The true and false statements need to be identified.
1. true
2. true
3. false
4. false
5. true
In an isosceles triangle two angles are equal.
Let the equal angle be [tex]x[/tex] and the other angle be [tex]y[/tex]
The sum of angles is [tex]180^{\circ}[/tex]
[tex]x+x+y=180\\\Rightarrow y=180-2x[/tex]
Now the value of [tex]x[/tex] cannot be [tex]90^{\circ}[/tex] or greater because
[tex]y=180-2\times 90=0[/tex]
[tex]x[/tex] has to be less than [tex]90^{\circ}[/tex].
The two equal angles must always be acute.
So, the statement is true.
If the side of an equilateral triangle is [tex]\dfrac{P}{3}[/tex]
Perimeter will be
[tex]\dfrac{P}{3}+\dfrac{P}{3}+\dfrac{P}{3}=P[/tex]
The statement is true.
An isosceles triangle that has the legs equal and also the base equal is called an equilateral triangle.
In an isosceles triangle the base may not be equal to the other two sides.
The statement is false.
Let [tex]x=1\ \text{unit}[/tex] be the length of the equal sides and [tex]y[/tex] the length of the other side
Permiter is
[tex]P=x+x+y\\\Rightarrow P=2x+y\\\Rightarrow P=2\times 1+y=2+y[/tex]
Since, the other side is not know the perimeter cannot be found.
The statement is false.
In an equilateral triangle all angles are [tex]60^{\circ}[/tex]
Exterior angle is found by subtracting the interior angle from [tex]180^{\circ}[/tex]
So, for an equilateral triangle the exterior angles will always be [tex]180-60=120^{\circ}[/tex]
The angles is greater than [tex]90^{\circ}[/tex] always.
The statement is true.

The sales tax for his purchase is 7.75%. Which of the following is closest to the total cost of David’s purchase?
Sale tax of 3 binders is closest to the david total purchase.
As per the given question
Binders=3Pen=5
Reams=2
Binder cost $3.50 each
Pen cost $1.15 each
Paper cost $4.00 each
Tax =7.75%
Let's solve it
3 binder =3×$3.50=10.5
5 pen = 5×$1.15=5.75
2 reams =2×4.00=8
Total cost before tax = 10.5+5.75+8=24.25
Total sale tax =24.25×7.75%=1.879375
Total purchase after sale tax =24.25+1.879375=26.129375
