9. Delia bought $45 dollars worth of clothes, but the total including sales tax came to $54. What is
the sales tax rate that Delia paid?
of the vehicles
Answer:
20%
Step-by-step explanation:
You want to know the tax rate if the added tax brings the cost of $45 purchase to a total of $54.
MultiplierThe multiplier applied to a purchase cost to add the tax is ...
(1 +r)
where r is the tax rate.
Here, that means ...
45(1 +r) = 54
1 +r = 54/45 = 1.20
r = 1.20 -1 = 0.20 = 20%
The tax rate Delia paid on the articles she bought was 20%.

It can be shown that center C is (1,-5) and that the radius is √45.
Find the equation of the tangent to the circle at the point (7,-2), giving your answer in the form ax + by + c=0, where a, b and c are integers.
Answer:
2x + y - 12 = 0
Step-by-step explanation:
The Tangent line will Always be perpendicular to the radius of a circle.
1. Find the slope of the radius that goes from the Center to the given point:
[tex]m=\frac{-2--5}{7-1}=\frac{3}{6}=\frac{1}{2}[/tex]
2. The slope of the Tangent at (7,-2) is the Negative (opposite) Reciprocal of the slope of the radius: [tex]\frac{1}{2}= > -2[/tex]
3. Write the equation of the Tangent in Point Slope Form:
[tex]y+2=-2(x-7)[/tex]
4. Distribute and rewrite in the form ax + by + c = 0
[tex]y+2=-2(x-7)\\y+2=-2x+14\\2x+y-12=0[/tex]
Find the absolute extrema if they exist, as well as all values of x where they occur, for the function f(x)=(x²-64)^{1/11} on the domain [-8,9]
Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice.
A. The absolute maximum is , which occurs at x= (Round the absolute maximum to two decimal places as needed. Type an exact answer for the value of x where the maximum occurs. Use a comma to separate answers as needed.)
B. There is no absolute maximum.
The critical points for the equation [tex]f(x)=(x^{2} +64)^{\frac{1}{11} }[/tex] is
[tex](x,f(x))[/tex] = [tex](0,2^{\frac{6}{11} })[/tex] = [tex](0,1.46)[/tex]. at x=0
The absolute maximum is at [tex](x,f(x))\\[/tex] = [tex](9,\sqrt[11]{145} )[/tex] = [tex](9,1.6)[/tex], at x=9.
What is the absolute maximum of an equation?
The highest conceivable values for f are represented by the absolute maximum (sometimes called the global maximum) of a function f(x) (x). Let's imagine the function's critical value, x=c, is present within its domain. If the inequality f(c) [tex]\geq[/tex] f(x), x is a domain, then the function f(x) is said to satisfy an absolute maximum when x=c.
To find the critical points, we find the value of f'(x) and equate to 0.
[tex]\frac{d}{dx} (\sqrt[11]{x^{2}+64} )=0[/tex]
we get x=0.
We see that f'(x) exists for all x between [-8,9].
We also find the endpoints, that is -8 and 9.
Then we calculate f(x) at critical points and endpoints.
We calculate f(x) at 0, -8, and 9.
We get,
for x=0, f(x)= [tex]2^{\frac{6}{11} }[/tex]
for x=-8, f(x)= [tex]2^{\frac{7}{11} }[/tex]
for x=9, f(x)= [tex]\sqrt[11]{145}[/tex]
We see that the value is maximum at x=9, and f(x) becomes [tex]\sqrt[11]{145}[/tex].
Hence we get the absolute maximum is [tex](x,f(x))\\[/tex] = [tex](9,\sqrt[11]{145} )[/tex] = [tex](9,1.6)[/tex]

Morris Company applies overhead based on direct labor costs. For the current year, Morris Company estimated total overhead costs to be $408,000, and direct labor costs to be $2,040,000. Actual overhead costs for the year totaled $386,000, and actual direct labor costs totaled $1,820,000. At year-end, Factory Overhead is:
At year-end, Factory Overhead is debit of $34000.
What is profit and loss?
A profit and loss (P&L) statement could be a monetary report that has a outline of a company’s revenue, expenses and profit. It provides investors and alternative interested parties an insight into however an organization is working and whether or not it's the flexibility to get a profit.
Main Body:
Estimated total overhead costs = $456,000
Estimated direct labor costs = $2,280,000
Actual overhead costs= $422,000
Actual direct labor costs= $1,940,000
To calculate the factory overhead, we need to first calculate Estimated overhead rate.
Estimated overhead rate = Estimated total overhead costs / Estimated direct labor costs
= $456,000 / $2,280,000
= 0.2
= 20%
Therefore;
Actual Factory overhead = Actual direct labor cost × application rate
= $1,940,000 × 20%
= $388,000
We can get the balance in the overhead account as shown below;
Balance = Actual overhead cost - Actual cost that should be applied
= $422,000 - $388,000
= $34,000 (Debit).
Hence there is debit of $34000.

Write the explicit and recursive rules for a geometric sequence given a table of values.
(a) The Explicit Rule for f(n) is 0.1 × 3n The Recursive Rule for f(n) is f(n-1) × 3. (b) The Explicit Rule for f(n) is 100 × 0.1ⁿ The Recursive Rule for f(n) is f(n-1) × 0.1
What is Explicit rule ?The explicit rule states that the value of the sequence at each term is 0.1 multiplied by 3 raised to the power of n. The recursive rule states that the value of the sequence at each term is equal to the value of the preceding term multiplied by 3. This can be seen in the table of values where each value is 3 times the preceding value.
Given,
n = 0,1,2,3,4…
f(n) = 0.1,0.3, 0.9, 2.7, 8.1
(b) The Explicit Rule for f(n) is 100 × 0.1ⁿ, The Recursive Rule for f(n) is f(n-1) x 0.1
Given,
n= 0,1,2,3,4..
f(n) = 100, 10, 1,0.1, 0.01
The explicit formula is the formula to calculate the value of the sequence directly without using any previous terms. The recursive formula uses the previous term to calculate the value of the current term.
In this example, the explicit formula is 100 × 0.1ⁿ and the recursive formula is f(n) = f(n-1) × 0.1. This means that each term in the sequence is equal to the previous term multiplied by 0.1.
For example, the third term in the sequence is 1, so the fourth term is 1 × 0.1 = 0.1.
(c) The Explicit rule for f(n) is 1000 × 0.1⁽ⁿ ⁻ ¹⁾, The Recursive rule for f(n) is f(n-1) x 0.1
To solve,
f(5) = 1000 × 0.1⁽⁵ ⁻ ¹⁾(5-1)
= 1000 × 0.1⁴
= 1000 × 0.0001
= 0.1
Given,
n= 1,2,3,4,5…
f(n) = 1000, 100, 10, 1, 0.1
The explicit and recursive rules for this geometric sequence are both written as f(n) = 1000 × 0.1⁽ⁿ ⁻ ¹⁾. This means that the value of the sequence at any given point n will be equal to 1000 multiplied by 0.1 raised to the power of n-1. This means that the value of the sequence decreases by a factor of 0.1 for every increase in n.
In this case,
f(5) = 1000 x [tex]0.1^4[/tex]
= 0.1.
(d) The Explicit Rule for this geometric sequence is f(n) = 10⁽⁵⁰ ⁻ ³ⁿ⁾, where n is the term number of the sequence.
The Recursive Rule for this geometric sequence is f(n) = f(n-1) ÷ 10³, where f(n) is the value for the nth term of the sequence and f(n-1) is the value for the (n-1)th term of the sequence.
Given,
n= 1,2,3,4,5..
f(n) = 10⁵⁰,10⁴⁷, 10⁴⁴, 10⁴¹, 10³⁸….
The value for the 5th term of the sequence is f(5) = 10⁽⁵⁰ ⁻ ³⁽⁵⁾⁾ = 10³⁸. The explicit rule for this geometric sequence is f(n) = 10⁽⁵⁰ ⁻ ³ⁿ⁾, where n is the term number of the sequence. This means that the value of each term is determined by taking 10 to the power of 50 minus 3 multiplied by the term number.
The recursive rule for this geometric sequence is [tex]\frac{f(n-1)}{10^3}[/tex] which means that the value of each term can be calculated by dividing the previous term by 10 cubes. We can use

you have a bag of ping pong balls. you arrange all but 2 of the balls in an equilateral triangle. then you put all the balls back into the bag and create a new equilateral triangle where each side has one more ball than the first arrangement but this time you are 11 balls short. how many balls were in the first arrangement?
Answer:
The “edge” effect of a tetrahedral container with edge length of 1,000 mm would be 2*r*√3 (r = radius of ball, see diagram below). For a ping pong ball with a diameter of 40 mm, the edge effect would be 2*20*√3 = 69.28 mm. Subtract that from 1,000 mm and you get 930.72 mm of “available space” along the bottom row. Divide 930.72 mm by 40 mm per ball and you get 23.27. So you wouldn’t be able to fit 24 balls along the base, you’d only be able to fit 23 balls. With 23 balls, the total number that a tetrahedron could contain (T) would be T = n(n+1)(n+2)/6 = 2,300 balls, not 2,600.

A triangle has side lengths of 200 units and 300 units. Write a compound inequality for the range of the possible lengths for the third side,
Answer:
100<x<500
Step-by-step explanation:
We can create a system of inequalities by using the Triangle Inequality Theorem. This theorem states that the sum of two sides on a triangle is greater than the other sides.
1.) Figure out the first inequality. This would be 300+200>x, or x<500.
2.) Figure out the second inequality. This would be x + 200 > 300, or x>100.
3.) Figure out the third inequality. This would be x + 300 > 200, or x > -100.
4.) Combine these inequalities. By combining these inequalities, we would get 100<x<500.

6x − y < −3 , inequality matches the graph.
Step 1:
Find the equation of the line
we have A(0,3) , B(1,9)
The formula to calculate the slope between two points is equal to
m = (y₂-y₁) / (x₂-x₁)
Substitute the values:
m = (9-3) / (1-0)
m = 6/1
m = 6
The equation of the line into slope intercept form is equal to
y = mx + c
where
m is the slope
b is the y-intercept
In this problem we have
m = 6
b = 3 ----> the y-intercept is the point B
Substitute the values:
y = 6x + 3
Step -2
Find the equation of the inequality
we know that:
The solution is the shaded area above the dashed line
so, the inequality is equal to
y > 6x + 3
rewrite
-6x + y > 3
6x - y < -3
Step 3
Using a graphing tool
The x-intercept is the point
The y-intercept is the point
The slope of the dashed line is positive, the graph in the attached figure.

to serve one person at a local restaurant it takes 10 minutes to serve pot five people it takes 18 minutes right and solve an equation to find the number of minutes it will take to serve a party of eight
By finding an evaluating a linear equation we will see that it takes 24 minutes to serve a group of 8 people.
How long takes to serve a party of eight?
Let's assume that the relation between the number of people and the time it takes to serve them is linear.
A general linear equation is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If the line passes through two points (x1, y1) and (x2, y2), then the slope is:
a = (y2 - y1)/(x2 - x1)
Here we have two points:
1 person, 10 minutes, written as (1, 10)
5 people, 18 minutes, written as (5, 18)
Then the slope is:
a = (18 - 10)/(5 - 1)
a = 8/4 = 2
Then the linear equation is:
y = 2x + b
To find the value of b, we can replace the values of one of the points, I will use (1, 10) so we will get:
10 = 2*1 +b
10 = 2 + b
10 - 2 = b
8 = b
The linear equation is:
y = 2x + 8
For 8 customers, the time will be:
y = 2*8 + 8
y = 24
It will take 24 minutes to serve 8 people.
