Answer:

$6240

Step-by-step explanation:

Find the rate by dividing property tax by the appraisal value.

[tex]\frac{3840}{160000}=0.024[/tex]

Now multiply the appraised value by this rate to find the property tax.

[tex]260000*0.024=6240[/tex]

The property tax on a home appraised at $260,000 is $6,240.

To find the property tax on a home appraised at $260,000, we can set up a proportion using the given information. The property tax on a $160,000 home is $3,840, so we have:

$160,000 : $3,840 = $260,000 : x

Using cross-multiplication, we can solve for x:

x = ($260,000 * $3,840) / $160,000

Calculating this, we find that the property tax on a home appraised at $260,000 is $6,240.

Answer:

consistent  

Solution at (3,2)

Step-by-step explanation:

A consistent and independent solution to a system of linear equations is one point

A consistent and dependent solution to a system of linear equations is where they are the same line ( they could also be called equivalent)

An inconsistent solution is where there is no solution, the lines do not cross

Since the lines cross at exactly one point, this is a consistent and dependent solution

The solution is at x = 3  ( 3 units to the right of the origin)

and y = 2 ( 2 units up from the origin)

Final answer:

The student missed the conversion from minutes to hours. The correct conversion is 26 hours × 60 minutes/hour × 60 seconds/minute, which equals 93,600 seconds.

Explanation:

Identifying the Missed Conversion Step

The student was attempting to convert 26 hours into seconds but arrived at an incorrect result of 1560 seconds. The error occurred because the student skipped the correct conversion ratio between minutes and hours. For such conversions, it is essential to use the correct conversion factors: 60 minutes per hour and 60 seconds per minute.

Correct Conversion Process

To convert 26 hours to seconds:

First, convert hours to minutes: 26 hours × 60 minutes/hour = 1560 minutes.

Then, convert minutes to seconds: 1560 minutes × 60 seconds/minute = 93,600 seconds.

Therefore, the correct number of seconds in 26 hours is 93,600 seconds.

where n ! = n(n - 1)(n - 2).... × 3 × 2 × 1

8[tex]P_{3}[/tex]

= 8 ! / (8 - 3) !

= 8 ! / 5 !

ANSWER

[tex]^8P_3 = 336[/tex]

EXPLANATION

Recall that;

[tex]^nP_r = \frac{n!}{(n - r)!} [/tex]

The given expression is:

[tex]^8P_3[/tex]

We substitute n=8 and r=3

[tex]^8P_3 =\frac{8!}{(8- 3)!} [/tex]

[tex]^8P_3 =\frac{8!}{(5)!} [/tex]

This simplifies to :

[tex]^8P_3 =\frac{8 \times 7 \times 6 \times 5!}{5!} [/tex]

We cancel out the common factors to get:

[tex]^8P_3 = 8 \times 7 \times 6[/tex]

[tex]^8P_3 = 336[/tex]

Answer:

The length of the shorter piece is  13 inches

Step-by-step explanation:

Let's represent the longer piece of pipe with the variable L and the shorter piece of pipe with variable S.

Since the pipe is going to be the length of  L and S together, we can make this equation:

L+S=52

Also we know that the longer piece is three times the shorter piece or

L=3S

Substitute the second equation into the first equation.

L+S=52

3S+S=52

4S=52

Divide both sides by 4

4S/4=52/4

S=13 inches

The length of the shorter piece is 13 inches....

To find the length of longer piece, put the value S=13 in L=3S

L=3S

L=3(13)

L=39 inches

The length of the longer piece is 39 inches....

296 inches

Step-by-step explanation:

The perimeter is the sum of sides of a rectangle

As the length is in feet while the width is in inches, a unit conversion must take place

As 1  feet  equals to 12 inches

Answer:

A. y - 7 = -4(x + 2)

Step-by-step explanation:

Insert the coordinates into the formula with their CORRECT signs. Remember, in the Point-Slope Formula, y - y₁ = m(x - x₁), all the negative symbols give the OPPOSITE term of what they really are. In addition, I recall that perpendicular lines have OPPOSITE MULTIPLICATIVE INVERSE [RECIPROCAL] rate of changes [slopes], so -4 really should be replaced with ¼, but if your assignment says otherwise, then this is the answer.

To find the equation of a line perpendicular to y=-4x -1 that passes through (-2, 7), we take the negative reciprocal of -4 to find the slope of the perpendicular line. Plugging in the values (-2, 7) and 1/4 for the slope, we get the equation y - 7 = 1/4(x + 2). Therefore, the correct answer is A. y - 7 = -4(x + 2).

To find the equation of a line perpendicular to a given line, we need to determine the slope of the perpendicular line. The given equation is in the form y = mx + b, where m represents the slope. The slope of the given line is -4. To find the slope of the perpendicular line, we take the negative reciprocal of -4, which is 1/4. Now that we have the slope, we can use the point-slope form of a linear equation, which is y - y1 = m(x - x1), where (x1, y1) is a point on the line. Plugging in the values (-2, 7) for (x1, y1) and 1/4 for the slope, we get the equation y - 7 = 1/4(x + 2). Therefore, the correct answer is A. y - 7 = -4(x + 2).

By applying the principle of inclusion-exclusion and considering students in History, we find that 3 students are in neither Math Competition classes nor Geometry.

To determine how many students are in neither Math Competition classes nor Geometry, we can use the principle of inclusion-exclusion. We have 50 students in total, with 25 in Math Competition classes and 29 in Geometry. However, since 19 students are in both classes, they were counted twice when we added the students in Math Competition classes and Geometry together. Thus, we subtract the number of students in both to avoid double-counting:
(25 + 29 - 19) = 35 students are in at least one of the math classes. Additionally, 12 students are in a History class and no math classes. Therefore, the number of students in at least one class (math or history) is 35 + 12 = 47.

Finally, to find the number of students in neither class, we subtract the number of students in at least one class from the total number of students:
50 - 47 = 3 students are in neither Math Competition classes nor Geometry.

Answer:

or

10.6301458127

Step-by-step explanation:

Plug the coordinated into this equation and make sure you match up the corrdinates in the correct order

d = √(x2 - x1)^2 + (y2 - y1)^2

The number next to the number does NOT mean multiply it mean like this

(x2, y2)  and (x1, y1) so you would plug them in like this:

d = √(-6 - 2)^2 + (4 - (-3))^2

d = √(-8)^2 + (7)^2

d = √(64 + 49

d = √113

or 10.6301458127

Answer with Step-by-step explanation:

The distance(d) between the points (a,b) and (c,d) is given by:

[tex]d=\sqrt{(c-a)^2+(d-b)^2}[/tex]

Here, we have to find distance between (2,-3) and (-6,4)

(a,b)=(2,-3) and (c,d)=(-6,4)

[tex]d=\sqrt{(-6-2)^2+(4-(-3))^2}[/tex]

[tex]d=\sqrt{8^2+7^2}[/tex]

[tex]d=\sqrt{64+49}[/tex]

[tex]d=\sqrt{113}[/tex]

Hence, the distance between the points (2 -3) and (-6 4) on the coordinate plane is:

[tex]\sqrt{113}[/tex]

Kasey has $53.63 withheld from her weekly paycheck of $865 for Social Security, which is calculated by multiplying her weekly pay by the Social Security tax rate of 6.2%.

The question asks us to calculate how much is withheld from Kasey's paycheck for Social Security.

With a weekly pay of $865, we need to find 6.2% of that amount since that is the percentage deducted for Social Security taxes.

To find this amount, we multiply $865 by 0.062.

Calculation: $865 × 0.062 = $53.63

Therefore, $53.63 is withheld from Kasey's paycheck each week for Social Security.

Explanation:

first, ignore the -4p for now. do the small equation without the variable. SO, we would do 7 - 5 = 2.

there aren't any addition symbols being used in the equation and there aren't any other numbers with the p variable. this means that the -4p will stay the same. so we would end up with -4p - 2

(this isn't the normal way of solving this, but I did my own way and got the same answer)

Answer:

The complete factorization is 3x² (x - 5)² ⇒ 2nd answer

Step-by-step explanation:

* Lets revise how to factorize a trinomial

- Find the greatest common factor of the coefficients of the three terms

∵ The trinomial is 3x^4 - 30x³ + 75x²

- The greatest common factor of 3 , 30 , 75 is 3

∵ 3 ÷ 3 = 1

∵ 30 ÷ 3 = 10

∵ 75 ÷ 3 = 25

∴ 3x^4 - 30x³ + 75x² = 3(x^4 - 10x³ + 25x²)

- Now lets find the greatest common factor of the variable x

∵ x² is the greatest common factor of the three terms

∵ x^4 ÷ x² = x²

∵ 10x³ ÷ x² = 10x

∵ 25x² ÷ x² = 25

∴ 3(x^4 - 10x³ + 25x²) = 3x² (x² - 10x + 25)

- Lets factorize (x² - 10x + 25)

∵ √x² = x

∵ √25 = 5

∵ 2 × 5 × x = 10x

∴ x² - 10x + 25 is a completing square

∴ (x² - 10x + 25) = (x - 5)²

∴ 3x² (x² - 10x + 25) = 3x² (x - 5)²

* The complete factorization is 3x² (x - 5)²

Answer:

3x^2 (x-5)^2

Step-by-step explanation:

3x^4 − 30x^3 + 75x^2

We can factor out a 3x^2 from each term

3x^2 (x^2 -10x +25)

The term inside the parentheses can be factored

What 2 numbers multiply to 25 and add to -10

-5*-5 = 25

-5+-5 = -10

3x^2 (x-5) (x-5)

3x^2 (x-5)^2
