The Rate of Tax for his state is 2.3%.
What is tax rate?
The ratio at which a business or individual is taxed in a tax system is known as the tax rate. Statutory, average, marginal, and effective tax rates are some of the ways that are used to present them. The terms inclusive and exclusive can be used to present these rates when applied to a tax base.
Annual Salary of Marcus Hatfield is = $43500
His Exemption from the tax is = $2000
He pays tax on the remaining amount i.e.
$43500 - $2000 = $41500.
His contribution toward the tax is $ 954.50,
Let the Rate of tax is x, thus
[tex](\frac{X}{100} *41500) = 954.50\\ x = \frac{95450}{41500} \\x = 2.3[/tex]
Thus, the rate of tax is 2.3% of his salary.
Hence, the Rate of Tax for his state is 2.3%.

Using elimination to solve the system of equations.
3x-5y=11
5(x+y)=5
Answer:
3x - 5y = 11
5(x + y) = 5
Expand the second equation:
5x + 5y = 5
Add both equations:
3x - 5y = 11
5x + 5y = 5
8x = 16
Solve for x:
8x = 16
x = 2
Input x in any equation and solve for y:
3(2) - 5y = 11
6 - 5y = 11
-5y = 5

3w^2-12w=-12
use quadratic formula to solve
Answer:
To solve the quadratic equation 3w^2 - 12w = -12, we can use the quadratic formula:
x = (-b +/- sqrt(b^2 - 4ac)) / (2a)
In this case, a = 3, b = -12, and c = -12. Plugging these values into the formula, we get:
w = (-(-12) +/- sqrt((-12)^2 - 43(-12))) / (2*3)
Simplifying, we get:
w = (12 +/- sqrt(144 + 144)) / 6
w = (12 +/- sqrt(288)) / 6
w = (12 +/- sqrt(288)) / 6
w = (12 +/- 16.97) / 6
w = (12 +/- 16.97) / 6
w = 28.97/6 or -4.97/6
w = 4.828 or -0.828
Therefore, the solutions to the equation 3w^2 - 12w = -12 are w = 4.828 and w = -0.828.
Answer:
w = 2
Step-by-step explanation:
[tex]3w^{2} -12w=-12\\3w^{2} -12w+12 = 0\\[/tex]
[tex]\frac{-b + \sqrt{b^{2} - 4ac} }{2a}[/tex]

According to the table, what wa the rate of change between 2018 and 2021?
The rate of change in the attendance of students between 2018 and 2021 is 1.24.
What is the rate of change?The term "rate of change" (ROC) describes the rate at which something changes over time.
Thus, it is not the number of individual changes themselves but rather the acceleration or deceleration of changes (i.e., the rate).
The rate of change is a tool used in finance to comprehend price returns and spot trend momentum.
Divide the change in y-values by the change in x-values to determine the average rate of change.
Identifying changes in measurable values like average speed or average velocity calls for the knowledge of the average rate of change.
So, according to the given table:
The rates of change between 2018 and 2021 are:
2018/2021
93/75
1.24
Therefore, the rate of change in the attendance of students between 2018 and 2021 is 1.24.

You use a garden hose to fill a wading pool. if the water level rises 17 centimeters every 5 minutes and you record the data point of (15, y), what is the value of y? use slope to justify your answer.
The line has a 17/5 slope and y has a value of 51 which will be (15, 51).
What is the slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
The general equation for every straight line is y = MX + c, where m is the gradient (or degree of steepness) of the line and c is the y-intercept (the point in which the line crosses the y -axis).
So, the water level rises by 17 cm in 5 minutes.
Then in 15 minutes, the water will rise by:
15 * 17/5
3*17
51
Then (x, y) will be (15, 51).
Obtaining the slope as follows:
Formula: m = y1 - y2/x1 - x2
m = y2 - y1/x2 - x1
m = 17 - y/5 - x
m = 17/5
Therefore, the line has a 17/5 slope and y has a value of 51 which will be (15, 51).

On Thursday when the correct time is 5:00h, watch shows 4:24h.
What is ratio?Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.
If a and b are two values, their ratio will be a:b,
Given that,
The watch is set at 11:00 h on Sunday.
Also, the watch loses 8 seconds in every hour.
To determine the time in watch on Thursday,
In one day total hours = 24 hours.
from Sunday 11:00 to Thursday 11:00
Total hours = 24 x 4 = 96 hours
And 11:00 to 5:00, total = 6 hours
Total hours = 96 + 6 = 102 hours
Since, watch loses 8 seconds in 1 hour
So in 102 hours watch losses = 102 x 8 = 816 seconds
816 seconds = 816/60 minutes = 13.6 minutes
The watch loses 13.6 minutes in 102 hours.

How to Graph the Equation of a Line?The equation of a line, where m is the slope or unit rate, and b is the y-intercept or starting value, is expressed as y = mx + b in the slope-intercept form.
Given the situation above, first determine the value of the starting value / y-intercept (b) and that of the slope / unit rate (m).
The starting value / y-intercept is b = 300.
The slope / unit rate is m = - 50 [this is negative because the distance from home reduces as she drives at the speed of 50 mph]
To write the equation, substitute m = -50 and b = 300 into y = mx + b:
y = -50x + 300.

Given (x – 7)2 = 36, select the values of x. x = 13 x = 1 x = –29 x = 42
Answer: x = 25
Step-by-step explanation:
(x-7) = 36/2
x-7 = 18
x = 18 +7
x = 25
Answer: x = 1 and x = 13.
Step-by-step explanation: To solve the equation (x - 7)^2 = 36, we can first rewrite the equation as x^2 - 14x + 49 = 36.
Next, we can rewrite the equation as x^2 - 14x + 13 = 0.
To solve for x, we can then use the quadratic formula:
x = (-b +/- sqrt(b^2 - 4ac)) / (2a)
where a = 1, b = -14, and c = 13.
Substituting these values into the formula, we get:
x = (14 +/- sqrt(14^2 - 4(1)(13))) / 2
x = (14 +/- sqrt(196 - 52)) / 2
x = (14 +/- sqrt(144)) / 2
x = (14 +/- 12) / 2
The values of x are therefore 1 and 13.
