Answer:
$129
Step-by-step explanation:
80 + 2(20) = 80 + 40 = 120
With tax: 100 + 7.5 = 107.5%
107.5/100 × 120
129
Answer:
129
Step-by-step explanation:
First find the cost for how much was purchased
boots: 80
2 shirts: 2*20 = 40
80+40 = 120
The tax is the cost times the tax rate
tax = 120 * 7.5%
= 120 * .075
9
The total cost is the cot plus the tax
total cost = 120+9
=129
What is the midpoint of EC?
Answer:
The correct answer is first option
(t + p, r)
Step-by-step explanation:
Points to remember
midpoint formula
Length of a line segment with endpoints (x1, y1) and (x2, y2) is given by,
Midpoint= [(x2 + x1)/2 , (y2 + y1)/2]
To find the midpoint of EC
Let (x1, y1) = E(2t, 0) and (x2, y2) = C(2p, 2r)
Midpoint = [(2t + 2p)/2 , (0 + 2r)/2]
= (2(t + p)/2 , 2r/2)
= (t + p, r)
Therefore midpoint of EC = (t + p, r)

The value of x and y are 3 and 3 respectively in the given system of equations.
A system of equations is a set of two or further equations that own an identical set of unknowns. The thing of solving a system of equations is to determine the values for the unknowns that quench all of the equations in the system.
It is given that the system of equations is,
2x - y = 0
x + y = 9
Now, from the first equation, we get
y = 2x
On putting the above value of y in the second equation, we get
x + 2x = 9,
3x = 9,
x = [tex]\frac{9}{3}[/tex]
x = 3.
Now putting this value of x in the first equation, we get
2 [tex]\times[/tex] 3 + y = 9
6 + y = 9
y = 9 - 6
y = 3.
So, x = 3 and y = 3 in the above system of equations.

Square OSER, ER equals (2a+b) what is the area of square OSER
Answer:
4a² + 4ab + b² units²
Step-by-step explanation:
Area of a square = Length²
ER is a length of the square
ER = (2a + b)
Area of a square = (2a + b)² = (2a + b)(2a + b) = (2a)(2a) + (2a)(b) + (2a)(b) + (b)(b) = 4a² + 4ab + b²
The area of the square OSER = [tex]4a^{2}+4ab+b^{2}[/tex] sq unit
Step-by-step explanation:
Given,
Length of each side(ER) = (2a+b) unit
To find the area of the square OSER.
Formula
The area of a square with each side a unit is [tex]a^{2}[/tex] sq unit
[tex](a+b)^{2}= a^{2} +b^{2} +2ab[/tex]
Now,
The area of the square OSER = [tex](2a+b)^{2}[/tex] sq unit
= [tex]4a^{2}+4ab+b^{2}[/tex] sq unit [ by using the formula of ([tex]a+b)^{2}[/tex]]

The coordinates of the vertices of quadrilateral ABCD are (7, -7), (4, -10), (1.5, -2.5), and (6, -3), respectively.
If quadrilateral ABCD is rotated 180° counterclockwise about the origin, what are the coordinates of D’?
A. (6, 3)
B. (3, -6)
C. (-6, 3)
D. (-3, 6)
C. Coordinates of D' (-6,3)
Step-by-step explanation:
When any figure is rotated 180° in the counterclockwise direction, then the coordinates of the vertices is changed into its opposite sign.
(x, y) → (-x, -y)
The coordinates of the vertices of quadrilateral ABCD is changed when it is rotated 180 degrees counterclockwise about the origin as,
A (7,-7) → A'(-7,7)
B (4,-10) → B' (-4,10)
C (1.5, -2.5) → C' (-1.5, 2.5)
D (6, -3) → D'(-6,3)
So the coordinates of D' will be (-6,3)

(100 POINTS) Can anyone solve this math equation for me? Thank you!
Answer:
Step-by-step explanation:
Given that,
x^8/x^a=x²
Applying indices
Division rule a^m ÷ a^n = a^(m-n)
Then,
x^8/x^a=x²
x^(8-a)=x²
For this to be equal means that, the power are equals since they have the same base
Then, 8-a=2
8+2=a
So, a=10
Taking the second equation
(x^6)^b=x¹²
Using indices again
x^(6b)=x¹²
Also, for this to be equal
6b=12
Then, b=12/6
b=2
Then, b=2 and =10
We need to find b-a.
b-a=2-10=-8
Then, the answer to b-a is -8

You have inherited land that was purchased for $30,000 in 1960. The value of the land increased by approximately 5% per year. What is the approximate value of the land in the year 2011?
Answer:
$361,223
Step-by-step explanation:
Each year, the value is multiplied by 1+5% = 1.05. After 51 years, it has been multiplied by that factor 51 times, so is now ...
$30,000×1.05^51 ≈ $361,223
Final answer:
To find the approximate value of land purchased for $30,000 in 1960 with a 5% annual increase by 2011, we use the compound interest formula which results in an approximate value of $447,187.25.
Explanation:
To determine the approximate value of land in the year 2011, which was purchased for $30,000 in 1960 with an average annual increase of 5%, we will use the formula for compound interest. This situation can be treated as a compound interest problem where the initial principal is the initial land value, the rate is the annual increase, and the time is the number of years the land has appreciated.
The compound interest formula is [tex]A = P(1 + r/n)^(nt),[/tex] where A is the future value of the investment/loan, including interest, P is the principal investment amount (initial value of land), r is the annual interest rate (annual increase in value), n is the number of times that interest is compounded per year, and t is the time the money is invested or borrowed for, in years.
In this scenario, P is $30,000, r is 0.05 (5% expressed as a decimal), n is 1 since we are compounding annually, and t is 51 (2011 - 1960).
Therefore,
[tex]A = 30,000(1 + 0.05/1)^(1*51).[/tex]
Carrying out the calculation gives us the approximate value of the land in 2011.
[tex]A = 30,000(1.05)^51[/tex]
Approximate value of the land in 2011 = $447,187.25

A.) 12 Inches
B.) 18 Inches
C.) 36 Inches
D.)48 Inches
Answer:
it is 18
Step-by-step explanation:
that the ansewer if you divid
Final answer:
The length of the rectangle with a perimeter of 60 inches and a width of 12 inches is 18 inches, calculated using the perimeter formula for rectangles and solving for the length.
Explanation:
The question asks us to find the length of a rectangle given its perimeter and width. To solve this, we use the formula for the perimeter of a rectangle, which is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width. In this case, we have P = 60 inches and w = 12 inches.
So, substituting the given values into the formula, we get:
60 = 2l + 2(12)
First, calculate the double of the width:
2(12) = 24 inches
Now, subtract this value from the total perimeter to find the double of the length:
60 - 24 = 36 inches
Finally, divide by 2 to find the length of the rectangle:
36 / 2 = 18 inches
Therefore, option B, 18 inches, is the correct answer for the length of the rectangle.
