The original price of a scooter is 89.99 before tax. When Trey bought the headphones they rang up 49.50 before tax. She then paid sales tax of 8% on the discounted price.
Part A: What is the percent discount on the headphones? Show all work and steps in your solution.
Part B: What is the total amount that Trey paid for the headphones including tax?
Answer:
A) About a 55% discount
WORK:
We can make an equation
89.99x=49.50
Where x is the percent discount
Now solve for X
You’ll get about 0.55
B) 53.46 with tax
WORK:
Mulitply 49.5 by 1.08
We can use 1.08 since the 49.50 is already the 100 percent and the 8 percent is just extra so when multiplied it should give you 53.46
Double check:
We can also just find 8 percent of 49.5 and get 3.96
When added, it should result in 53.46

Use the formula d = rt to find the distance, rate, or time
16. r = 4, t = 11 17. d = 36, t = 4
Answer:
16. d = distance
r = rate
t = time.
We know that the rate = 4, and time = 11.
=> d = 4 * 11
=> d = 44
17. We know that distance = 36, and time = 4.
=> 36 * r* 4
=> 36 = 4r
=> 36/4 = 4r/4
=> r = 9
Solve the system of equations. 6x - 3y = 3 -2r +y = 14 What number would you multiply the second equation by in order to eliminate the x-terms when adding to the first equation? What number would you multiply the first equation by in order to eliminate the y-terms when adding to the second equation?
9514 1404 393
Answer:
3
Step-by-step explanation:
Assuming your two equations are ...
6x -3y = 3-2x +y = 14You want to find the multiplier k such that ...
6 + (-2)k = 0 . . . . total x-coefficient after the equations are combined
Dividing by 2 gives ...
3 - k = 0
3 = k . . . . . . add k
The multiplier needed is 3.
A garden is made up of 4 triangles. A gardener wants to put a fence around the garden to keep animals from eating the vegetables. How much fence should the gardener purchase?
Answer:
18
Step-by-step explanation:
The total fence the gardener should purchase is the perimeter of the triangle and is given by the equation P = 18 feet
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Given data ,
Let the perimeter of the triangle be represented as P
P = total fence the gardener should buy
Let the triangle be represented as ΔABC
Now , the inner triangle is represented as ΔXYZ
And , The measure of XZ = 4 feet
The measure of XY = 2 feet
The measure of YZ = 3 feet
where X is the midpoint of AB
Y is the midpoint of BC
And , Z is the midpoint of AC
Now , AX = BX be equation (1)
BY = CY be equation (2)
AZ = CZ be equation (3)
Now , from the triangle ,
XY = ( 1/2 ) BC
XY = ( 1/2 ) AC
YZ = ( 1/2 ) AB
Substituting the values in the equation , we get
The measure of BC = 8 feet
The measure of AB = 6 feet
The measure of AC = 4 feet
So , the perimeter of the triangle P = measure of BC + measure of AB + measure of AC
And , perimeter of the triangle P = 8 + 6 + 4
Perimeter of the triangle P = 18 feet
Therefore , the value of P is 18 feet
Hence , the fence around the triangle is 18 feet

Answer:
Some answers to the reducing fraction sheet
Q14 = 4/5 because divide 12 and 15 by 3
Q15=can't be reduced because 11 is a prime number so it can't be divided by anything
Q17=can't be reduced because 17 is a prime number
Q18=can't be reduced because 13 is a prime number
Q19=38/9 because 114 and 27 would be divided by 3
Q20= -1/1 because you would divide both 14,529 by itself would equal to - 1/1

The longest runway at an airport has the shape of a rectangle and an area of 1,934,400 square feet. This runway is 160 feet wide. How long is the runway?
Answer:
The length of the runway = 12090 feet
Step-by-step explanation:
The formula involving the area of a rectangle is
[tex]A=wl[/tex]
here
'w' is the width 'l' is the lengthGiven
Area A = 1,934,400 square feet
Width w = 160 w
Length l = ?
Using the formula
[tex]A=wl[/tex]
substituting the values
1,934,400 = 160 × l
l = 1,934,400 / 160
l = 12090 feet
Therefore, the length of the runway = 12090 feet
.) Rhianna is training for a marathon. She is now able to run 4 5/6 miles in ½ hour. What is Rhianna's rate in miles per hour? Express your answer as a mixed number and include the rate statement in the end.
Answer:
9 2/3 miles /hour
Step-by-step explanation:
Rate can also be referred to as speed.
The formula for Rate or Speed = Distance(Miles) /Time(hours)
Rhianna's distance = 4 5/6 miles
Rhianna's Time = 1/2 hour
Rate = 4 5/6 miles/ 1/2 hour
Rate = 29/6 miles ÷ 1/2 hour
Rate = 29/6 × 2/1
Rate = 29/3 miles/hour
Rate = 9 2/3 miles /hour
Rhianna's rate = 9 2/3 miles /hour

HELP PLEASE! ASAP 8TH GRADE
Step-by-step explanation:
Well, let's walk through it, shall we?
3x − 5 = 4 + 3x
Our first step is to simplify both sides of the equation.
3x − 5 = 4 + 3x
3x + −5 = 4 + 3x
3x − 5 = 3x + 4
Then, we subtract 3x from both sides.
3x − 5 − 3x = 3x + 4 − 3x
−5 = 4
FInally, we'll add 5 to both sides.
−5 + 5 = 4 + 5
0 = 9
In conclusion, your answer is:
This would be false. x = -3 is not a solution to 3x - 5 = 4 + 3x
