Figure the 7% sales tax on $2.19 bottle of window cleaning solution and a gel pen which costs $2.75.
PLZ HELP I WILL GIVE OUT TONS OF POINTS!
Answer:
sales tax on a bottle of window cleaning solution = $0.1533
sales tax on a gel pen=$0.1925
Step-by-step explanation:
The price of bottle of window cleaning solution = $2.19
Sales tax =7%
Applying the tax, 7/100 * 2.19 = $0.1533
The price of a gel pen = $2.75
Applying the sales tax;
7/100 * 2.75 = $0.1925
The 7% sales tax on a $2.19 bottle of window cleaning solution and a $2.75 gel pen is around $0.35.
Explanation:To calculate the 7% sales tax on a $2.19 bottle of window cleaning solution and a $2.75 gel pen, you first need to find the total cost of the items. Add $2.19 and $2.75 which equals $4.94. This is your base amount on which you will calculate the sales tax.
To get the tax amount, multiply the total cost by the tax rate as a decimal (7% = 0.07). So, $4.94 * 0.07 = $0.35 approximately. This will be the sales tax charged on these items.
Therefore, if you buy a window cleaning solution and gel pen, you would pay around $0.35 in taxes assuming a 7% sales tax.

Dividing Polynomials with Tables Isiah is dividing 2x3 - x2 + 2x + 5 by x + 1 using a division table. His work is shown here. What is the value of A?
Answer:
5
Step-by-step explanation:
We are asked to find the value of A. We know from the question that we need to have the sum of -3x and (A)x equal the third term of the original polynomial, which is 2x. written out in an equation, it looks like this.
[tex]-3x+(A)x=2x[/tex]
We can simplify the equation if we add 3x to both sides, which then leaves us with this.
[tex](A)x=5x[/tex]
We can further simplify the equation by dividing both sides by x. This leaves us with our last equation for this problem.
[tex]A=5[/tex]
Finally, we have our answer. We can also verify that this is a valid integer by multiplying our, now completed, quotient by the divisor and adding the remainder, which in this case, our remainder is 0, so we will not be including it in our operation.
[tex](x+1)(2x^{2}-3x+5)[/tex]
If our calculations were all correct, the product of these polynomials should equal our dividend, verifying our integer is valid; lo' and behold, it is.

In the figure below, \overline{AD} AD start overline, A, D, end overline and \overline{BE} BE start overline, B, E, end overline are diameters of circle PPP. What is the arc measure of \stackrel{\LARGE{\frown}}{CD} CD ⌢ C, D, start superscript, \frown, end superscript in degrees? ^\circ ∘ degrees
Answer:
The measure of the arc CD = 64°
Step-by-step explanation:
It is required to find the measure of the arc CD in degrees.
So, as shown at the graph
BE and AD are are diameters of circle P
And ∠APE is a right angle ⇒ ∠APE = 90°
So, BE⊥AD
And so, ∠BPE = 90° ⇒(1)
But it is given: ∠BPE = (33k-9)° ⇒(2)
From (1) and (2)
∴ 33k - 9 = 90
∴ 33k = 90 + 9 = 99
∴ k = 99/33 = 3
The measure of the arc CD = ∠CPD = 20k + 4
By substitution with k
∴ The measure of the arc CD = 20*3 + 4 = 60 + 4 = 64°

Answer:
Two solutions were found :
x = 6
x = -1
Step by step solution :
Step 1 :
Equation at the end of step 1 :
(3x2 - 15x) - 18 = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
3x2 - 15x - 18 = 3 • (x2 - 5x - 6)
Trying to factor by splitting the middle term
3.2 Factoring x2 - 5x - 6
The first term is, x2 its coefficient is 1 .
The middle term is, -5x its coefficient is -5 .
The last term, "the constant", is -6
Step-1 : Multiply the coefficient of the first term by the constant 1 • -6 = -6
Step-2 : Find two factors of -6 whose sum equals the coefficient of the middle term, which is -5 .
-6 + 1 = -5 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -6 and 1

What are the end behaviors of f(x) = -2(x - 2)5?
O
A. Both ends go down.
O
B. The left end goes down; the right end goes up.
O'C. Both ends go up.
O
D. The left end goes up; the right end goes down.
Answer:
Step-by-step explanation:
D.The left end goes up and the right end goes down because this is a first order function
The end behavior of the function f(x) = -2(x - 2)^5 is that the left end goes up and the right end goes down. This is determined by the odd degree and negative leading coefficient of the function.
Explanation:The end behaviors of a function can be determined by looking at the highest degree term, also known as the leading term. In this case, for the function f(x) = -2(x - 2)^5, the highest degree is odd (5), and the coefficient, -2, is negative.
Odd degree with a negative leading coefficient means that the end behaviors of this function will be: as x approaches negative infinity (moves left), the function values will go toward positive infinity (up), and as x approaches positive infinity (moves right), the function values will go toward negative infinity (down).
So the correct option here is: D. The left end goes up; the right end goes down.

1. How many people were sent the
message on Wednesday? Explain
how you know.
On Wednesday, 64 people were sent the message as each of the 16 recipients forwarded the message to 4 other people.
Explanation:To determine the number of people sent the message on Wednesday, we need to consider the number of people who received the message on each day. On Monday, Zach sent the message to 4 friends, so there were 4 recipients. On Tuesday, each of the 4 friends forwarded the message to 4 other people, resulting in a total of 4 friends x 4 recipients = 16 recipients.

Answer:
∠ K = 35° and ∠ L = 105°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
let ∠ K = x then ∠ L = 3x
Sum the angles and equate to 180
3x + x + 40 = 180, that is
4x + 40 = 180 ( subtract 40 from both sides )
4x = 140 ( divide both sides by 4 )
x = 35
Thus
∠ K = 35° and ∠ K = 3x = 3 × 35 = 105°

x - 2y - 7 = 0
Step-by-step explanation:
To find the equation of a line that passes through (-5, -3) and (3,1)
All we need to do is to use the find the slope and then plug it into the straight line equation
straight line equation : y - [tex]y_{1}[/tex] = m (x - [tex]x_{1}[/tex])
[tex]x_{1}[/tex] = -5 [tex]y_{1}[/tex] = -3 [tex]x_{2}[/tex] = 3 [tex]y_{2}[/tex] = 1
m = slope = [tex]y_{2}[/tex] - [tex]y_{1}[/tex] / [tex]x_{2}[/tex] - [tex]x_{1}[/tex]
= 1 -(-3) / 3 -(-5)
=4/8
=1/2
m=1/2
So, we can now plug in our value into the equation;
y - [tex]y_{1}[/tex] = m (x - [tex]x_{1}[/tex])
y - (-5) = [tex]\frac{1}{2}[/tex] [x - (-3)]
y + 5 = [tex]\frac{1}{2}[/tex](x+3)
y + 5 = [tex]\frac{x + 3}{2}[/tex]
cross-multiply
2(y + 5) = x + 3
2y + 10 = x + 3
take 2y and 10 to the right-hand side of the equation;
x + 3 - 2y - 10 = 0
x - 2y - 7 = 0
Therefore the equation of the line is x - 2y - 7 = 0

When Justin goes to work, he drives at an average speed of 60 miles per hour. It takes about 1 hour and 30
minutes for Justin to get to work. His car travels about 25 miles per gallon of gas. If gas costs $3.65 per
gallon, how much money does Justin spend on gas to get to work?
Answer:
$13.14
Step-by-step explanation:
60 mi/1 hour = x mi/1.5 hours
x = 90 mi to drive to work
25 mi/1 gallon = 90 mi/y gallons
y = 3.6 gallons to get to work
$3.65/1 gallon = $z/3.6 gallons
z = $13.14
Justin spends $13.14 on gas to get to work.
What is an Equation?An equation is a mathematical statement formed when two expressions are equated using an equal sign.
The equations are useful in determination of unknown parameters.
The average speed of Justin when he goes to work is 60 miles/hour.
The time taken to reach to work is 1 hour 30 minutes.
Justin's car travels 25 miles for 1 gallon of gas.
The cost for one gallon of gas is $3.65 per gallon.
The total miles travelled is 60 miles/ hour * 1 hour 30 minutes.
Total miles travelled = 60 * (1.5)
Total miles travelled = 90 miles
The gas used for 25 miles is 1 gallon
The gas used for 90 miles is 90/25 = 3.6 gallon.
The cost of gas is $3.65 per gallon
The cost of 3.6 gallon is 3.65 *3.65
The cost of the gas used to get to work is $13.14.
