You purchase a t-shirt for $9.55 and a pair of jeans for 18.12 from Old Army at 7% sales tax.
How much change should you receive if you give the cashier two twenty-dollar bills?
Answer:
$10.39 is the change
Step-by-step explanation:
We start by calculating the total score
9.55 + 18.12 = 27.67
we now calculate the sales tax
This is 7% of the total
= 7% of 27.67
7/100 * 27.67
= $1.94
The total now comes;
1.94 + 27.67 = $29.61
The total was 2 * 20 = $40
The change was;
$40 - $29.61 = $10.39

Find Four Numbers that form a geometric progression such that the second term is less than the first by 35, and the third term is greater than the fourth term by 560. (Note: there should be 3 different possible geometric sequences)
Answer:
-35/3, -140/3, - 560/3, -2240/37, -28, 112, - 448Step-by-step explanation:
The terms are:
a₁, a₂, a₃, a₄Given:
a₁ = a₂ + 35a₃ = a₄ + 560Use the nth term formula:
a₂ = a₁ra₃ = a₁r²a₄ = a₁r³Substitute:
a₁ = a₁r + 35 ⇒ a₁(1 - r) = 35a₁r² = a₁r³ + 560 ⇒ a₁(1 - r)r² = 560Divide the second equation by the first:
r² = 560/35r² = 16r = √16r = ± 4Use the first equation to find the first term:
a₁( 1 ± 4) = 351. a₁ = 35/-3 = -35/32. a₁ = 35/5 = 7We have two sequences:
r = 4
-35/3, -140/3, - 560/3, -2240/3r = -4

Find the additive inverse of each linear expression
1. 3x - 6
2. -9x + 3
3. -4x -8
Step-by-step explanation:
G(x) = 2/3 x - 6 switch x and y around and solve for y.
y = 2/3 x - 6
x = 2/3 y - 6
x + 6 = 2/3 y
3/2 x + 9 = y
Book price $ 60. The book went up in price on the 15th

PLS HELP WILL MARK BRAINLIST
Answer:
T=39.46
Step-by-step explanation:
13(t+13)=676
multiply 13 by t and by 13
then you will have 13t + 169=676
isolate the variable
13t + 169= 676
substract 169 from both sides
13=507 divided both side by 13
T=39

Looking at the y table, when we subtract 1 from them, they become multiples of -3
So we multiply x by -3 then add 1
Calculate the gradient of the line using rise/run method.
Given:
The graph of line.
To find:
The gradient of the line using rise/run method.
Solution:
We know that the gradient of a line is also known as slope.
[tex]Slope=\dfrac{Rise}{Run}[/tex]
Consider the two intercepts, then rise is distance between origin and y-intercept and run is the distance between origin and the x-intercept. But rise must be negative because the value of y decreased from 3 to 0.
[tex]Rise=-3[/tex]
[tex]Run=2[/tex]
Now,
[tex]Slope=\dfrac{Rise}{Run}[/tex]
[tex]Slope=\dfrac{-3}{2}[/tex]
The gradient of the line is [tex]-\dfrac{3}{2}[/tex].
Therefore, the correct option is C.
Which measurement is closest to the area of the circle in square centimeters ? A. 31.4cm² B. 78.5cm² C.62.8² D.50.2cm²
Answer: it’s a
Step-by-step explanation: took the test got it right
The required measurement closest to the area of the circle in square centimeters is 78.5cm². Option B is correct.
What is an area circle?The area of the circle is given by the pie times square of the radius.
Area of circle = πr^2
Here,
Let the radius of the given circle be r = 5 cm
Area of the circle = πr²
Substitute the value in the above expression,
Area of the circle = π 5²
Area of the circle = 78.5cm²
Thus, the required measurement closest to the area of the circle in square centimeters is 78.5cm². Option B is correct.

A ladder needs to reach a second-story window that is 15 feet above the ground and make an angle with the ground of 71°. How far out from the building does the base of the ladder need to be positioned? Round your answer to the nearest tenth.
The base of the ladder needs to be ______ feet away from the wall.
Answer:
5.2 feet
Step-by-step explanation:
It helps if you can make a drawing.
You are looking for the adjacent side of the 71° angle in a right triangle and 15 is the opposite side of the angle.
Let x = the distance from the building to the base of the ladder
Tan 71 = 15/x
xtan71 = 15
x = 15/tan 71 = 5.2 feet

What is function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.
here, we have,
For this case we observe the cut point with the y axis in:
(0, 7)
The function that complies with this is:
y = 2 ^ (x + 2) +3
We have then:
y = 2 ^ (0 + 2) +3
y = 2 ^ (2) +3
y = 4 + 3
y = 7
Answer:
The answer for this case is given by:
y = 2 ^ (x + 2) +3
