The income tax can be paid by the teacher =$ 9212.
What is income tax:An income tax is a sort of tax that is levied on the earned and unearned income of an individual or corporation.
For instance, the United States levies a federal income tax on its residents, regardless of where they reside—in the country or overseas. The majority of the money the US government receives comes from this income tax.
Here we have
The annual salary of a teacher is $ 65,800
The rate of income tax = 14%
The income tax can be paid = 14% of 65800
=> [tex]\frac{14}{100} \times 65800[/tex]
= [tex]14 \times 658[/tex]
= 9212

In triangle DEF angle F i 120 degree and f= 4/3e. Find the meaure of angle D and angle E
The measure of the angle D and F can be calculated form the total measure of the Angle of the triangle that is 180.
In the triangle DEF, F is 120 degree and F is 4/3rd of E. A straight angle is just a straight line which is where it gets its name. the sum of a triangles angles 180. It is proved by angular defect and triangles area. The angle sum of a triangle will always be equal to 180°. The angle sum of a quadrilateral is equal to 360°, and a triangle can be created by slicing a quadrilateral in half from corner to corner. Since a triangle is essentially half of a quadrilateral, its angle measures should be half as well.
Angle F = 120 degree
F= 4/3 E
E= 90 degree
The sum of the angle is 180. so,
D + E + F = 180
Putting all the values we can find the measure of angle D and Angle E.

Answer:
x = 11midline = 16baseline = 32Step-by-step explanation:
You have a triangle with its midline length given as x+5 and its parallel base line length given as 3x-1. We presume you want to know the value of x and the lengths of the segments.
MidlineThe midline is half the length of the parallel base line, so you have ...
x +5 = 1/2(3x -1)
Solution2x +10 = 3x -1 . . . . . . . multiply by 2
11 = x . . . . . . . . . . . . . add 1-2x
The midline length is x+5 = 11+5 = 16.
The base line length is 3x-1 = 33 -1 = 32, twice the length of the midline.
The solution to the triangle is ...
x = 11midline = 16base line = 32As a pharmacist, you are responsible for knowing about medication dosage, and how long a dose stays in the patient's system. Let's look at an example of a common medication, called ibuprofen. When a patient takes a 400 mg dose of ibuprofen, it releases into the bloodstream at a certain rate, and then decreases over time. The function that models this concentration of medicine over time is complex and looks like this:
P(t) = 0.5t + 3.45t³ - 96.65t² + 347.7t, when 0 ≤t≤6 . In this function above, P(t) is the amount of medication (in mg) in the

A power outage affected all homes and businesses within a 5 mi radius of the power station. If the power station is located 1 mi west and 3 mi north of the center of town, find an equation of the circle consisting of the furthest points from the station affected by the power outage.
Answer: x^2 - 2x + y^2 - 6y + 10 = 0.
Step-by-step explanation: The power station is located 1 mi west and 3 mi north of the center of town, which means that it is located at the point (1, 3) on the coordinate plane. The power outage affected all homes and businesses within a 5 mi radius of the power station, which means that the furthest points from the station affected by the power outage are located on a circle with a radius of 5 mi.
The equation of a circle with center (h, k) and radius r is given by:
(x - h)^2 + (y - k)^2 = r^2
Substituting the values for the center of the circle (h, k) = (1, 3) and the radius r = 5, the equation of the circle consisting of the furthest points from the power station affected by the power outage is:
(x - 1)^2 + (y - 3)^2 = 5^2
This simplifies to:
x^2 - 2x + 1 + y^2 - 6y + 9 = 25
Combining like terms, the equation becomes:
x^2 - 2x + y^2 - 6y + 10 = 0
This can be written in standard form as:
x^2 - 2x + y^2 - 6y + 10 = 0
Therefore, the equation of the circle consisting of the furthest points from the power station affected by the power outage is x^2 - 2x + y^2 - 6y + 10 = 0.

The costs for the given candy are $7 for strawberry taffy and $6 for banana taffy. By writing equations and simplifying them, we get the requiredd values.
How to solve two equations?To solve two equations,
Rewrite one of the equations for one of its variables.Substitute it in the other equation.On simplifying, we get a value for one variable.Then, substitute in one of the equations, and we get another variable.This method of solving is called the substitution method.Calculation:It is given that, two friends visited a taffy shop.
Winton bought - 2 kg of strawberry taffy and 1 kg of banana taffy for $20.
Audrey bought - 4 kg of strawberry taffy and 4 kg of banana taffy for $52.
Then, we can write the above information into equations as
2S + B = 20 ...(1)
4S + 4B = 52 ...(2)
Where S represents strawberry taffy and B represents banana taffy.
From (1), we can write
B = 20 - 2S
Then, on substituting in (2), we get
4S + 4(20 - 2S) = 52
⇒ 4S + 80 - 8S = 52
⇒ -4S = 52 - 80 = -28
⇒ 4S = 28
∴ S = 7
Thus, the cost of strawberry taffy is $7.
On substituting S = 7 in (1), we get
2(7) + B = 20
⇒ 14 + B = 20
⇒ B = 20 - 14
∴ B = 6
Thus, the cost of banana taffy is $6.

Answer:
Step-by-step explanation:
To plot the positive rational numbers on the number line, you can use the following steps:Start by drawing a number line, with 0 at the left end and positive numbers increasing as you move to the right.Place the first number, 12, on the number line. You can place it to the right of 0, since it is a positive number.Place the next number, 134.16, to the right of 12. You can place it farther to the right, since it is a larger number.Place the next number, 310/8, to the right of 134.16. Since 310/8 is equal to 38.75, you can place it slightly to the right of 134.16, but still to the left of 39.Place the next number, 0, at the left end of the number line, since it is equal to 0.Place the next number, 1, to the right of 0, since it is a positive number.Place the next number, -2.05, to the left of 0, since it is a negative number.Place the final two numbers, 2 and 3, to the right of 1, since they are both positive numbers.The resulting number line should look something like this:-2.05 0 1 2 3 12 134.16 38.75 (310/8)

B.) Y = -3x + 7
C.) Y = -3x +5
D.) Y = 1/3x -3
The equation of a line parallel to -3x - y= -4 and passing through a point (1,4) is y = -3x + 7.
How to find the equation of a line?The equation of a line can be represented in slope intercept form as follows:
y = mx + b
where
m = slopeb = y-interceptTherefore, the line is parallel to -3x - y = -4 and it passes through (1, 4).
Parallel lines have the same slope.
Hence,
-3x - y = -4
y = -3x + 4
The slope of the line is -3.
Let's find y-intercept using (1, 4)
y = -3x + b
4 = -3(1) + b
4 + 3 = b
b = 7

We know that a triangle has 180 degree
62 + 84 = 146 degree
180 - 146 = 34 degree
34 degrees is the angle inside the triangle. The inside angle must add with the outside angle = 180 degree

Paul drives his delivery van 675 miles in 3 days. at this rate, how far will he drive in 15 days?
a. 45 miles
b. 225 miles
c. 2,025 miles
d. 3,375 miles
Therefore, the correct answer is 3,375 miles, or option (d) is the correct option.
To find out how far Paul will drive in 15 days, we need to determine his average distance per day and then multiply that number by 15. To find Paul's average distance per day, we can divide the total distance he drove in 3 days by the number of days:
675 miles / 3 days = 225 miles/day.
So Paul drives an average of 225 miles per day. If he continues to drive this same distance every day, he will drive 225 miles/day * 15 days = <<225*15=3375>>3,375 miles in 15 days.

if the coefficient of determination is a positive value, then the regression equation
Answer:
close to 1, good fit
Step-by-step explanation:
If the coefficient of determination is a positive value, it means that the regression equation is a good fit for the data. The coefficient of determination, denoted by r^2, is a measure of how well the regression equation explains the variation in the data. A value of r^2 close to 1 indicates that the regression equation explains a large portion of the variation in the data, while a value of r^2 close to 0 indicates that the regression equation does not explain much of the variation in the data.
Therefore, if the coefficient of determination is a positive value, it means that the regression equation is a good fit for the data and explains a significant portion of the variation in the data. This means that the regression equation is likely to be a reliable model for the data and can be used to make predictions about the values of the dependent variable based on the values of the independent variable.
