On the first 4 quizzes of her chemistry class, nadia got an average score of 88. what does she need on the next quiz to have an overall average of 90?

450/5 = 90

The measurement of the supplement of an angle is 7 times the measure of the complement. find the measure of the complement

Answers

x = angle 90 - x = measure of complement of x 180 - x = measure of supplement of x From the information given in the problem, we get this: 180 - x = 7 (90 - x) 180 - x = 630 - 7x -x + 7x = 630 - 180 6x = 450 x = 450/6 x = 75. Now we prove that x = 75° is the correct angle: x = 75° = measure of angle 90° - 75° = 15° = meaure of complement 180° - 75° = 105° = 7 (15°)

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

Carys is checking her tax bill for the last year.

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?
Show your working.

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!!!!!

Answers

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.

Final answer:

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.

You have set up a webpage for your company. your logo took up 2/7 of your allotted space on the main page and the location information takes up 1/10 of the allotted space on a page. how much more space did the logo use than the location information? please express your answer as a fraction and percent.

Answers

So we want to find how much more space the logo took up.

So just subtract the location info from the logo space.

2/7 - 1/10

To subtract, you just want to find a common denominator. In this case it would be 70.

2/7 * 10/10 - 1/10 * 7/7

20/70 - 7/70

Then just subtract.

13/70

So that's the fraction. For the percent, just divide.

13/70 = 0.186 ish

Dish A has n₁ = 1.75 x 10¹⁸ bacteria.
Dish B has n₂ = 6.25 x 10¹⁵ bacteria.

Calculate n₁/n₂.

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.

Answers

Its the second choice
It is a one-to-one function

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.

Therefore, option B is true.

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

Answers

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.
