Carys is checking her tax bill for the last year.
The tax rates were as follows:
No tax of the first £11 000 of earnings.
Earnings in excess of £11 000 and up to £43 000 taxed at a rate of 20%.
Earnings in excess of £43 000 and up to £150 000 taxed at a rate of 40%.
Earnings over £150 000 taxed at a rate of 45%.
Last year Carys earned £45 600 before tax.
How much tax did she pay in total?

I am having a lot of trouble finding the answer to this. I looked it up on this website hoping I could find how to solve it but unfortunately that didn't happen. Can anyone help ?!!! Anxious to know!!!!!
Answer:
£7,440
Step-by-step explanation:
We have been given the tax rates as follows:
$0-$11,000 = No tax.
$11,000-$43,000 = 20%.
$43,000-$150,000 = 40%.
Earnings over $150,000 = 45%.
Since last year Carys earned $45,600, so we will have to find the tax paid by her for 11,000-43,000 at rate of 20%, then the tax for amount over 43,000 at the rate of 40%
Therefore, Carys paid an amount of $7,440 in tax.
Carys paid no tax on the first £11,000 of her income. She paid £6,400 in tax on her earnings between £11,000 and £43,000, and £1,040 on her earnings between £43,000 and £45,600. The total tax paid was £7,440.
Explanation:To calculate how much tax Carys paid on her earnings of £45,600, we need to apply the given tax rates to the appropriate segments of her income. Here is the step-by-step working:
She pays no tax on the first £11,000.Earnings between £11,000 and £43,000 are taxed at 20%. To find the tax for this bracket, we subtract £11,000 from £43,000 to get the taxable amount, which is ¤32,000. Then we calculate 20% of ¤32,000, which amounts to £6,400.Earnings above £43,000 up to £150,000 are taxed at 40%. Carys earned ¤2,600 in this bracket (because £45,600 - £43,000 = ¤2,600). The tax on this amount is 40% of ¤2,600, which is £1,040.Since Carys did not earn over £150,000, she does not pay any tax at the 45% rate.We now add the tax from the second and third bullet points to get the total tax that Carys pays: £6,400 + £1,040 = £7,440.
Therefore, Carys paid a total of £7,440 in tax for the last year.

What is the initial value of the exponential function shown on the graph
Answer:
The initial value of the exponential function is 2
Step-by-step explanation:
A function is a mathematical relation in which we input the values of a domain that generate the output values of a range.
Initial value of the function is the output value of the function when the input is x =0.
As shown in the graph:
The exponential function cut at the point (0, 2)
where;
y=2 when x=0.
Therefore, the initial value for the exponential as shown in the figure is, 2.
Use the trapezoid rule to estimate the area under the graph of y = x2 + 2 for values of x from 0 to 3.
The measurement of the supplement of an angle is 7 times the measure of the complement. find the measure of the complement
Answer:
15⁰
Step-by-step explanation:
Angke = x
Complement = 90 - x
Supplement = 180 - x
Given:
180 - x = 7 (90 - x)
180 - x = 630 - 7x
6x = 450
x = 75
Complement = 90 - 75 = 15⁰

The temperature in degrees Celsius, c, can be converted to degrees Fahrenheit, f, using the equation mc026-1.jpg. Which statement best describes the relation (c, f)? It is a function because –40°C is paired with –40°F. It is a function because every Celsius temperature is associated with only one Fahrenheit temperature. It is not a function because 0°C is not paired with 0°F. It is not a function because some Celsius temperatures cannot be associated with a Fahrenheit temperature.
Answer:
B is true.
Step-by-step explanation:
given that the temperature in degrees Celsius C can be converted to degrees Fahrenheit F
For every Celsius temperature we get only one value of Fahrenheit .
Function: function is a mapping between two sets .Each member of set is mapped with one value of set B.
Given function is one-one because for every value of Celsius we get a unique value of Fahrenheit
Hence, it is a function because every Celsius temperature is associated with only one Fahrenheit temperature.

The cost of a classified ad is based on a daily rate plus a flat service fee. One day cost $3.50 and four days cost $800 write and solve a linear equation to find the cost of a 7-day ad.
x= 11
hope this helped :)
The linear equation that gives the cost in dollars, y, in terms of the number of days the ad appears, x is: y = $1.50x + $2.00
The cost of a 7-day ad is $12.50.
Let, the daily rate is "d" dollars and the flat service fee is "f" dollars.
We are given two pieces of information:
One day costs $3.50.
Four days cost $8.00.
Using this information, we can set up two equations:
For one day: d + f = $3.50
For four days: 4d + f = $8.00
Now, we need to solve this system of linear equations to find the values of "d" and "f."
Subtract Equation 1 from Equation 2 to eliminate "f":
(4d + f) - (d + f) = $8.00 - $3.50
3d = $4.50
Now, divide both sides by 3 to solve for "d":
d = $4.50 / 3
d = $1.50
Now that we have the value of "d," we can find the value of "f" by substituting "d" into Equation 1:
d + f = $3.50
$1.50 + f = $3.50
Now, subtract $1.50 from both sides to solve for "f":
f = $3.50 - $1.50
f = $2.00
So, the daily rate (d) is $1.50, and the flat service fee (f) is $2.00.
We get, a linear equation that gives the cost in dollars, y, in terms of the number of days the ad appears, x is: y = $1.50x + $2.00
Now, to find the cost of a 7-day ad, we can use the daily rate and multiply it by the number of days (7):
Cost of a 7-day ad = 7 * $1.50 + $2.00
Cost of a 7-day ad = $10.50+ $2.00 = $12.50
The cost of a 7-day ad is $12.50.

A rectangle is a quadrilateral having the four sides and the sum of the angles is 180 in the rectangle the opposite two sides are equal and parallel and the two sides are at 90-degree angles.
Given that:-
The length of a photograph is 1 cm less than twice the widthThe area is 91 cm²The length and the width will be calculated as:-
let the width = x
length = 2x - 1
91 = x ( 2x - 1 ) = 2x² - x
2x² - x - 91 = 0

Complete the chart and determine the solution of the equation f(x) = g(x)?
A.) x = -1
B.) x = 0
C.) x = 2
D.) x = 25
Answer:
x = -1.75 makes f(x) = g(x)
Step-by-step explanation:
See the attached for a table. You will notice that for x=-1.75, the values of f(x) and g(x) are the same. That means x = -1.75 is the solution to f(x)=g(x).
Upon calculating the values for f(x) and g(x), it's determined that f(x) = g(x) when x = -7/4. The options provided do not include this answer, suggesting a possible typo in the question or answer choices.
Completing the Values and Finding the Solution for f(x) = g(x)
To complete the given table, we need to apply the functions f(x) = 9x + 7 and g(x) = 5x to the missing x values. For x = -2, g(x) equals -10 (since 5 * -2 = -10). For x = 0, f(x) is 7 (since 9 * 0 + 7 = 7), and for x = 2, f(x) equals 25 (since 9 * 2 + 7 = 25) and g(x) equals 10 (since 5 * 2 = 10).
To determine the solution for the equation f(x) = g(x), we set the two expressions equal to each other:
9x + 7 = 5x
By subtracting 5x from both sides, we get:
4x + 7 = 0
Now, subtracting 7 from both sides, we find:
4x = -7
Finally, by dividing both sides by 4, we get:
x = -7/4
None of the given options A, B, C, or D match x = -7/4, which might indicate there could be a typo in the question or answer choices.
Find the value of x that makes m ∥ n
Answer:
The value of x that makes m || n is x = 20
Step-by-step explanation:
Given a line that is intersected by another two lines (for example line ''m'' and line ''n'' like in the exercise) one of the conditions that makes m || n is that the alternate interior angles must be congruent. Understanding that congruent means the same.
In the exercise, one pair of alternate interior angles are (2x+20)° and 3x°.
We need this two angles to be congruent ⇒ [tex]3x=2x+20[/tex]
Solving this for ''x'' :
[tex]3x=2x+20\\3x-2x=20\\x=20[/tex]
The value of x that makes 3x° congruent to 2x+20° (that makes the alternate interior angles congruents) is x = 20
Answer:
20
Step-by-step explanation:
Theorem:
If two lines are cut by a transversal such that alternate interior angles are congruent, then the lines are parallel.
Lines m and n are cut by a transversal.
Angles 3x and 2x + 20 are alternate interior angles.
For lines m and n to be parallel, angles 3x and 2x + 20 must be congruent, so their measures must be equal.
3x = 2x + 20
x = 20
Answer: 20
