The Outdoor Furniture Center buys wooden benches for $50 each. The owner of the Outdoor Furniture Center sells the benches for a 120% markup. At the end of the season, the owner wants to sells all the benches that are in stock. He sells the benches for 20% off.
What is the total price of a bench with the 20% discount plus a 5% sales tax?
Practice
Show your work
Answer:
92.4
Step-by-step explanation:
50$ + 120% = 110
110 - 20% = 88
88 + 5% = 92.4
The total price of a bench with the 20% discount plus a 5% sales tax is $92.4.
What is Markup Percentage?Markup percentage is defined as the total profit of the commodity in terms of percentage. It is calculated by dividing the difference of the selling price and the cost with the cost and then multiply to 100.
Markup Percentage = [(sales price - cost) / cost] × 100
Cost of a bench = $50
There is 120% markup in the bench
Selling price = $50 + ($50 × 120%)
= $50 + ($50 × 1.2)
= $50 + $60
= $110
At the end of the season, owner gives 20% discount.
Price of the bench after 20% discount = $110 - (20% × 110)
= $110 - (0.2 × 110)
= $110 - $22
= $88
There is a sales tax of 5%.
Last selling price of the bench = $88 + (5% × $88)
= $88 + (0.05 × $88)
= $88 + $4.4
= $92.4
Hence, the owner sells the bench at the season at $92.4.

Find the value of a in the polygon below.
Answer:.
m= 116 degrees
a=41 degrees
Step-by-step explanation:
Explaination: add 89+50+64 = 203
the line that m is on should equal 180. so subtract 64 from 180 and you get 116 degrees. then add 89+50+64+116=319
360-319= 41
the whole polygon should equal 360 degrees

What is a slope?The slope or gradient of a line in mathematics is a numerical representation of the steepness and direction of the line.
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
To find the equation of the line that passes through the points (-4, 0) and (0, 4), we can use the point-slope form of the equation of a line as described in the definition.
First, let's find the slope of the line. We can use the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) = (-4, 0) and (x2, y2) = (0, 4):
m = (4 - 0) / (0 - (-4)) = 4 / 4 = 1
So the slope of the line is 1.
Next, let's choose one of the given points, say (-4, 0), and substitute its coordinates and the slope into the point-slope form:
y - 0 = 1(x - (-4))
Simplifying this equation, we get:
y = x + 4
So the equation of the line that passes through the points (-4, 0) and (0, 4) is y = x + 4.

What is m∠2 + m∠3? Explain. Two lines and two line segments. Lines A B and C D are parallel horizontal lines with point C directly below point A and point D directly below point D. A vertical segment extends from A to C. A diagonal segment extends from C to B. Angle B A C is labeled 1. Angle A C B is labeled 3. Angle B C D is labeled 4. Angle A B C is labeled 2. A. 180; m∠1 + 90 = 180, so m∠2 + m∠3 = 180. B. 180; m∠1 + 90 = m∠2 + m∠3, so m∠2 + m∠3 = 180. C. 90; m∠1 + m∠2 + m∠3 = 180. m∠1 = 90, so m∠2 + m∠3 = 90. D. 90; ∠2 and ∠3 are corresponding angles, so m∠2 + m∠3 = 90.
The line AB and the segments AC and BC form triangle ∆ABC, which gives the measure of m‹2 + m‹3 as following option;
C. 90°; m‹1 + m‹2 + m‹3 = 180°. m‹1 = 90°, so m‹2 + m‹3 = 90°
How can m‹2 + m‹3 in ∆ABC be calculated?From the given descriptions, we have;
Lines AB and CD are horizontal lines.
Segment that extends from A to C which is segment AC is a vertical line
Therefore;
m‹BAC = m‹1 = 90°
‹BAC, ‹ABC, and ‹ACB, which are angles 1, 2, and 3 are interior angles of ∆ABC
Which gives;
m‹1 + m‹2 + m‹3 = 180° (sum of interior angles of a triangle theorem)
Therefore;
90° + m‹2 + m‹3 = 180° (substitution property)
m‹2 + m‹3 = 180° - 90° = 90°
m‹2 + m‹3 = 90°
The correct option is therefore;
C. 90°; m‹1 + m‹2 + m‹3 = 180°. m‹1 = 90°, so m‹2 + m‹3 = 90°Learn more about the interior (and exterior) angles of a triangle here:

Select the correct answer. Which function has a domain of all real numbers? A.y=(x+2)^ 1/4 B.y=-x^ 1/2+5 C.y=-2(3x)^1/6 D.y=(2x)^1/3-7
The option D shows a function has a domain of all real numbers.
Which is the Domain of a Function?
The domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined.
Letter A - [tex]y=\left(x+2\right)^{^{\frac{1}{4}}\:}[/tex], as you have an even exponent, the results for y should be greater or equal than zero. Thus,[tex]\left(x+2\right)^{^{\frac{1}{4}}\:}=\sqrt[4]{x+2}[/tex]
Therefore, the function domain is x [tex]\geq[/tex]-2.
Letter B - [tex]y=-x^{\frac{1}{2}}^{\:}+5[/tex], as you have an even exponent, the results for y should be greater or equal than zero. Thus,[tex]-x^{\frac{1}{2}}^{\:}+5=-\sqrt{x} +5[/tex]
x [tex]\geq[/tex] 0
Therefore, the function domain is x [tex]\geq[/tex] 0.
Letter C - [tex]y=-2\left(3x\right)^{\frac{1}{6}}[/tex], as you have an even exponent, the results for y should be greater or equal than zero. Thus,[tex]-2\left(3x\right)^{\frac{1}{6}}=-2*\sqrt[6]{3x}[/tex]
3x [tex]\geq[/tex] 0
x [tex]\geq[/tex] 0
Therefore, the function domain is x [tex]\geq[/tex] 0.
Letter D - [tex]y=\left(2x\right)^{\frac{1}{3}}-7[/tex], as you have an odd exponent, the results for y has no undefined points nor domain constraints. Thus,[tex]\left(2x\right)^{\frac{1}{3}}-7=y=\sqrt[3]{2x} -7\\ \\[/tex]
Therefore, the function domain is [tex]-\infty \: < x < \infty \:[/tex].

Present age of Ram and Ravi are in the ratio

Answer:
Step-by-step explanation:
Ravi présent âge 15 because présent would be 20:15 and then it would turn into 25:20
Answer:
15 years old
Step-by-step explanation:
Given the ratio of their ages = 4 : 3 = 4x : 3x ( x is a multiplier )
Then in 5 years the ratio of their ages is 4x + 5 : 3x + 5 = 5 : 4, that is
[tex]\frac{4x+5}{3x+5}[/tex] = [tex]\frac{5}{4}[/tex] ( cross- multiply )
4(4x + 5) = 5(3x + 5) ← distribute both sides
16x + 20 = 15x + 25 ( subtract 15x from both sides )
x + 20 = 25 ( subtract 20 from both sides )
x = 5
Thus
Ravi's age is 3x = 3 × 5 = 15
