(0.04 x150=6)
lastly add 6 (your calculated sales tax) to your total sale price
getting a final answer of $156.00
And arithmetic sequence has a first term of 10 and the sixth term of 40. What is the 20th term of the sequuence?
Solution
The general form of the n-th term = a + (n-1)d
Here we are given the 1st term (a) = 10
6th term = 40
We need to find the 20th term.
Let's find the common difference.
6th term = 10 + (6 - 1) d
6th term is 40, so
40 = 10 + (6 -1)d
40 -10 = 5d
30 = 5d
d = 30/5
d = 6
The common difference is d = 6.
20th term = a + (n -1)d
= 10 + (20 -1)6
= 10 + 19*6
= 10 + 114
20th term = 124

37 is what percent of 144 to the nearest percent?
To find what percent 37 is of 144, divide 37 by 144, get the decimal form, multiply by 100, and round to the nearest whole number. The result is approximately 26%.
To calculate 37 as a percentage of 144, we use the following steps:
Divide 37 by 144 to get the decimal form of the ratio.Multiply the result by 100 to convert it to a percentage.After performing the division, we find that 37/144 \0.2569 (rounded to four decimal places). Multiplying this by 100, we obtain 25.69%, which we then round to the nearest whole number, giving us 26%.
The answer to the question "37 is what percent of 144 to the nearest percent?" is therefore 26%.

What is the slope of the line that passess between ( 0, 4 ) and ( -8, -2 )
Answer:
The slope is 3/4.
Step-by-step explanation:
Slope formula:
[tex]\displaystyle \frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\displaystyle \frac{(-2)-4}{(-8)-0}=\frac{-6}{-8}=\frac{-6\div2}{-8\div2}=\frac{-3}{-4}=\frac{3}{4}[/tex]
Therefore, the slope is 3/4, and the correct answer is 3/4.
If a polygon has 1127 diagonals, how many sides does the polygon have? (what’s the equation to solve or & answer)
We are given : Number of diagonals of a polygon = 1127 diagonals.
We know relation between number of diagonals and number of sides of the polygon.
[tex]\frac{n(n-3)}{2}=d[/tex], Where n is the number of sides of the polygon and d is number of diagonals.Plugging d=1127 in above formula, we get
[tex]\frac{n(n-3)}{2}=1127[/tex]
Multiplying both sides by 2, we get
[tex]n(n-3)=2254[/tex]
[tex]n^2-3n=2254[/tex]
[tex]n^2-3n-2254=0[/tex]
Solving quadratic equation by factoring, we get factors
[tex]\left(n-49\right)\left(n+46\right)=0[/tex]
Solving for n, we get
n-49=0
n=49.
n+46=0.
n=-46.
We can't take number of sides by a negative number.
Therefore, number of sides does the polygon have 49 side.

Which function is graphed below?
EASY POINTS!
Answer:
The correct answer is D. I hope i help you))
The correct answer is Option D. The graphed function consists of a constant value of 5 for (x < 2) and a linear equation with a positive slope for ([tex]x \geq 2)[/tex]
The graph represents a piecewise function. Let’s analyze it step by step:
Left Segment (for (x < 2)):
The graph is a horizontal line at (y = 5).
This corresponds to the piecewise component (f(x) = 5) for (x < 2).
Right Segment (for [tex](x \geq 2))[/tex]:
The graph is an oblique line passing through points (2,5) and (5,8).
The slope of this line is [tex](\frac{8 - 5}{5 - 2} = 1).[/tex]
It intersects the y-axis at (y = -2).
This corresponds to the linear equation (f(x) = x + 3) for ([tex]x \geq 2[/tex]).
Therefore, the function graphed is a piecewise function with two parts:
For (x < 2): (f(x) = 5)
For [tex](x \geq 2)[/tex]: (f(x) = x + 3)

If the hypotenuse of a right triangle is 15 feet and one of the other legs measures 12 feet, how many feet is the unknown side?
This is the Pythagorean theorem, that equation is a^2 + b^2 = c^2, but if you dont have b you can manipulate the equation, that equation is c^2-a^2=b^2. So you take 15^2 - 12^2 and that equals 81, then you take the square root of 81, which equals 9, so your answer would be 9 feet. Hope that helped :)
The unknown side of the right-angled triangle measures 9 feet. We found this using the Pythagorean theorem.
Explanation:This problem falls under the topic of Pythagoras theorem in Mathematics. The Pythagorean theorem describes the relationship between the lengths of the sides of a right-angled triangle. It is stated as: a² + b² = c², where c represents the length of the hypotenuse, and a and b are the lengths of the other two sides of the triangle.
If one side (say, a) of the right triangle is 12 feet and the hypotenuse (c) measures 15 feet, we can calculate the length of the other side (b) using the principle of the Pythagorean Theorem. By rearranging the theorem to solve for 'b', we get the equation:
b = √(c² - a²)
Substitute the given values into the equation:
b = √((15)² - (12)²) = √(225 - 144) = √81
Hence, the unknown side 'b' measures 9 feet.

What is the value of the x-coordinate that is 9 units to the left of (5,-8)
I need to know what 11, 14, and 15 are I don't remember how to do it
When you reflect a function in the x-axis, the first coordinate of a point stays the same, and the second coordinate changes sign (what was positive is now negative and vice versa). See the attached picture.
Question 11: f(x) = -5x + 2. The function changes to its opposite, so g(x) = -(-5x + 2) = 5x - 2.
When you reflect a function in the y-axis, the first coordinate of a point changes to its opposite, but the second coordinate stays the same. Replace x with -x .
Question 14: f(x) = |2x - 1| + 3. Replacing x with -x produces g(x) = |2(-x) - 1| + 3 which simplifies to g(x) = |-2x -1| + 3.
Question 15 works the same way as #14.

This is a Mathematics problem about perimeter. If Brian has 25ft of fencing and one side of the rectangle is 9ft, the equation created is 2x =16. Solving for x gives the other dimension as 8ft which means the kennel's dimensions are 9ft by 8ft.
Explanation:The subject of this question is Mathematics and it involves a problem of perimeter in geometry. In this problem, Brian has 25ft of fencing and one side of the rectangular area, the one against the garage, doesn't need fencing, and that side is 9ft.
Let the other side be 'x'. In a rectangle, opposite sides are equal. Since one of the sides is already fenced, we need fencing for only three sides. So we can create the equation 9 + x + x = 25. This simplifies to 2x = 16. Therefore, 'x' equals 8. The dimensions of the rectangular kennel are 9ft by 8ft.
