The scale factor of the transformation is 2.25

From the question, we have the following parameters that can be used in our computation:

Point H'(4.5, 6.75) is the result of dilating point H(2, 3)

This means that

The scale factor of the transformation = H'/H

Substitute the known values in the above equation, so, we have the following representation

Scale factor = (4.5, 6.75)/(2. 3)

Evaluate

Scale factor = 2.25

Hence, the scale factor is 2.25

To find the distance from the ranger's station to the forest fire, we can use the tangent function and the information given in the problem. The tangent of an angle is defined as the ratio of the opposite side to the adjacent side in a right triangle. In this case, we can use the angle of depression to the forest fire, the height of the ranger's station above the ground, and the distance from the ranger's station to the forest fire to form a right triangle.

We can then use the tangent function to find the distance from the ranger's station to the forest fire as follows:

tan(35°) = opposite/adjacent

opposite = tan(35°) * adjacent

opposite = tan(35°) * 100 feet

opposite = 0.7392 * 100 feet

opposite = 73.92 feet

Therefore, the distance from the ranger's station to the forest fire is approximately 74 feet. To the nearest tenth of a foot, this is 73.9 feet.

[tex]\textsf{2.} \quad x \leq 6.25[/tex]

3.  See attachment.

Step-by-step explanation:

Given information:

If the baseballs cost $4 each and x is the number of baseballs, then 4x represents the total cost of the baseballs.

The maximum amount of money available to spend on the baseballs is $25.

Therefore, the inequality to represent this is:

[tex]\large\boxed{4x \leq 25}[/tex]

Solve the inequality by dividing both sides by 4:

[tex]\implies \dfrac{4x}{4} \leq \dfrac{25}{4}[/tex]

[tex]\implies x \leq 6.25[/tex]

Note:  As x represents the number of baseballs you can buy, and as you cannot buy part of a baseball or negative baseballs, the real solution is 0 ≤ x ≤ 6.

To graph  x ≤ 6.25  on a number line:

To graph  0 ≤ x ≤ 6  on a number line:

The least to greatest or increasing order of the given data set will be 0.1375,0.25,5/8,11/16 thus, option (C) is correct.

Average Rate of Change

Functions are relationships that exist between two variables. Graphing them allows us to observe and predict their behavior. The graph of a function is a line or curve where we can determine random values directly and identify a set of results through it.

The rate of change is one of the calculations we can determine from a graph. It is the change of the function per unit. It is deriving from the slope of the line formed in the interval. The formula for determining the rate of change is:

The values of a and b in the expression x³ + ax³ + bx - 3 are a = 1 and b = -17

From the question, we have the following parameters that can be used in our computation:

x^3+ax^3+bx-3

Rewrite properly

So, we have

x³ + ax³ + bx - 3

The expression has a factor of x - 3

This means that

(3)³ + a(3)³ + b(3) - 3 = 0

So, we have

27 + 27a + 3b - 3 = 0

Evaluate the like terms

27a + 3b = -24

Divide by 3

9a + b = -8

The expression has a remainder of 15 when divided by x + 2

This means that

(-2)³ + a(-2)³ + b(-2) - 3 = 15

So, we have

-8 - 8a - 2b - 3 = 15

Evaluate the like terms

-8a - 2b = 26

Divide by -2

4a + b = -13

So, we have

9a + b = -8

4a + b = -13

Subtract the equations

5a = 5

Divide

a = 1

Recall that 4a + b = -13

So, we have

4(1) + b = -13

So, we have

b = -13 - 4

Evaluate

b = -17

Hence, the values are 1 and -17

Answer: 20

Step-by-step explanation: There are 2 ways to solve this problem. This is one way, it is a shortcut. So if you didn't know, 25% of 100 (the whole thing) is 1/4, so if you divide 80 by 1/4, you should get 20. The 2nd way is to set up a proportion, so it would be 25 over 100 = ? over 80. Now, you would cross multiply the 25 and 80 to get 2000. Then you take the 2000 and divide it by 100 to get 20. I hoped this explanation helped you.

Answer:

20

Step-by-step explanation:

Write 25% as 25/100

Since, finding the fraction of a number is same as multiplying the fraction with the number, we have

25/100 of 80 = 25/100 × 80

Therefore, the answer is 20

If you are using a calculator, simply enter 25÷100×80 which will give you 20 as the answer.

Her commission rate is 7.44%.

What is commission rate?

The payment that is either a fixed amount or a percentage of a sale is the commission rate. When they make a sale, people in commission-based professions like insurance brokers, real estate agents, and car salespeople are compensated.

The parameters given are;

The amount Mary earns annually = $28,000

The amount Mary grossed during a week = $658.00

The amount Mary had sold during the week to make the amount grossed during the week = $1673.19

Given that Mary makes $28,000 per year

Therefore;

The amount Mary earns per week = Amount earned per year/52

The amount Mary earns per week =  $28,000/52 = $538.46

The amount extra she made on commission = $658.00- $538.46= $119.54

The commission rate = Commission earned/(Amount of merchandise sold)×100

The commission rate = 119.54/1673.19 × 100 = 7.14%

For a taxable income of $1,80,900, the effective tax rate is 21.11%.

Marginal tax is the tax rate applied to an individual’s last dollar of income. It is the additional tax that must be paid on any additional income earned. In other words, it is the tax rate that applies to an individual’s income after all deductions. For example, if an individual’s income is $50,000 and the marginal tax rate is 25%, then the individual must pay an additional $12,500 in taxes on top of the $25,000 in taxes already paid on their $50,000 income.

Marginal tax rates are progressive, meaning that as an individual’s income increases, the marginal tax rate will increase as well. The marginal tax rate is important to understand because it helps individuals determine how much additional income they will need to earn in order to make up for the taxes they will have to pay on that income. It is also important to understand how marginal tax rates can affect tax planning strategies.

To determine the effective tax rate for a taxable income of $180,900, calculate the sum of the marginal tax rates for each tax bracket that the $180,900 falls into. The taxable income of $180,900 is greater than $89,075 and less than $170,050. The marginal tax rates for these two tax brackets are 22% and 24%, respectively. The sum of the marginal tax rates is 46%. Divide the sum by the taxable income of $180,900 to get the effective tax rate of 21.11%. Round the final answer to the nearest hundredth to get 21.11%.

What is proportionality?

Suppose there are two quantities. Proportionality indicates that if there is a change in the value of one quantity, the value of other quantity also changes but maintaining a constant ratio

Proportionality can be direct or inverse

Direct proportion

Two quantities are said to be in direct proportion if on increasing the value of one quantity, the value of other quantity also increases and vice versa.

For example cost of a commodity and quantity of a commodity are in direct proportion

Inverse proportion

Two quantities are said to be in inverse proportion if on increasing the value of one quantity, the value of other quantity decreases and vice versa.

For example Number of men and number of days taken by those men to complete a job.

Length of paver in the model = [tex]\frac{2}{3}[/tex] ft

Actual length of paver = [tex]\frac{1}{2}[/tex] ft

Let the constant of proportionality be k
