A wholesaler sells a guitar for $1,396.20. What is the percent markup based on cost if the wholesaler paid $780 for the guitar?
The Markup percentage based on cost if the wholesaler paid $780 for the guitar is 79%
Given,
The cost price of the guitar = $780
The selling price of the guitar = $1396.20
We have to find the markup percent based on the cost;
Markup percentage;
The gross profit of a unit, which is its sales price less its cost to produce or acquire for resale, is divided by the unit's cost to determine the markup %.
Markup percent = (Selling price - cost price) / cost price x 100
= (1396.20 - 780) / 780 x 100
= 616.20 / 780 x 100
= 0.79 x 100
= 79%
That is,
The Markup percentage based on cost if the wholesaler paid $780 for the guitar is 79%

Find the value of x .
Answer:
x = 113
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 8 , then
sum = 180° × 6 = 1080°
sum the interior angles and equate to 1080
x + 137 + 144 + 139 + 123 + 150 + 142 + 132 = 1080
x + 967 = 1080 ( subtract 967 from both sides )
x = 113
A poster is
than

that there is a 5
cm border on all
sides.
If the
area of the border
alone is 1350 cm²,
what are the
dimensions of the
poster
The dimension are 75 * 50 i.e, Width = 50 cm , Length = 75 cm
Define Dimension
A measurable extent of a particular kind, such as length, breadth, depth, or height.
Let,
T = how taller the poster is
W = how wide the poster is
According to question given,
T = W + 25 ---eq(i)
The total height is calculated by multiplying the top border by 5 and the bottom border by 5. The entire height is then multiplied by the border's width, 5, times 2, so there are two tall sides. then multiplying by 5 times 2 widths.The equation looks like that,
5 * (2 (T + 10)) + 5 * (2 * W) = 1350
Now substitute the eq(i) value,
5 * (2 ((W + 25) + 10)) + 5 * (2 * W) = 1350
Now, solve for W,
5 * (2W +50 + 20) + 10W = 1350
10W + 5(70)+ 10W = 1350
20W + 350 = 1350
20W = 1350 - 350
20W = 1000
W = 1000/20
W = 50
Now, put the W value in eq(i)
T = 50 + 25
T = 75
Therefore, The dimension are 75 * 50 i.e, Width = 50 cm , Length = 75 cm

The height, h of the parallelogram is 4 feet.
How to find the height of a parallelogram?A parallelogram is a quadrilateral with opposites sides equal to each other. Opposite sides of a parallelogram are also parallel to each other.
Opposite angles of a parallelogram are congruent. The consecutive or adjacent angles of a parallelogram is supplementary.
Therefore, the height of the parallelogram can be found as follows:
The sum of angles in a parallelogram is 360 degrees.
Hence,
sin ∅ = opposite / hypotenuse
where
∅ = one angle of the parallelogramsin ∅ = 3 / 6
sin ∅ = 1 / 2
∅ = sin⁻¹ 0.5
∅ = 30
Therefore,
30 + 30 + 2x = 360
where
x = angle of the parallelogram60 + 2x = 360
2x = 360 - 60
2x = 300
x = 300 / 2
x = 150
Let's find the height of the parallelogram using trigonometric ratios,
sin 30° = h / 8
cross multiply
h = 8 sin 30°
h = 8 × 0.5

Slope of one of the dotted lines: -1/3
Slope of the line of reflection: 3
From given figure, we can observe that the line of reflection passes through points (2, 8) and (0, 2)
We need to find the slope of the line of reflection and any dotted line.
Using the formula of slope, the slope of the line of reflection would be,
m1 = (y2 - y1)/(x2 - x1)
m1 = (2 - 8)/(0 - 2)
m1 = -6 / (-2)
m1 = 3
The dotted lines are perpendicular to the line of reflection.
Let m2 be the slope of any dotted line.
We know that the product of slopes of any perpendicular lines is -1.
so, m1 * m2 = -1
3 * m2 = -1
m2 = -1/3
So, the slope of dotted any line = - 1/3
Therefore, Slope of one of the dotted lines: -1/3
Slope of the line of reflection: 3

The Pythagorean Theorem states that the squares on the hypotenuse of a right triangle, or, in standard algebraic notation, a² + b² = c².
What is meant by Pythagorean Theorem?The Pythagorean Theorem states that the squares on the hypotenuse (the side across from the right angle) of a right triangle, or, in standard algebraic notation, a² + b² = c².
The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a fundamental relationship between a right triangle's three sides in Euclidean geometry. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
First use the Pythagorean theorem. a² + b² = c²
then take the first derivative of it to get
2a(a') + 2b(b') = 2c(c')
Now figure out how far the train is after 4 seconds
6(4)=24
70² + 24² = c²
c = 74

Answer:
104 children and 195 adults
Step-by-step explanation:
let a represent number of adults and c represent number of children , then
a + c = 299 → (1)
7a + 2c = 1573 → (2)
multiplying (1) by - 2 and adding to (2) will eliminate c
- 2a - 2c = - 598 → (3)
add (2) and (3) term by term to eliminate c
5a + 0 = 975
5a = 975 ( divide both sides by 5 )
a = 195
substitute a = 195 into (1) and solve for c
195 + c = 299 ( subtract 195 from both sides )
c = 104
104 children and 195 adults were admitted

The rate of the slowest car is 86 km/hr using the concept of relative velocity.
What is Relative velocity?Relative speed is the rate at which one moving body moves in relation to another. The differential between two moving bodies determines their relative speed while they are traveling in the same direction. However, when two bodies are traveling in opposition to one another, the relative speed is determined by averaging their respective speed.
Let the speed of 1st car is v₁.
Let the speed of 2nd car is v₂.
v₁- v₂ = 18 km/hr --- (1)
And using the concept of relativity.
S(rel) = D(rel)/time
S(rel) = 360 / 2
S(rel) = 190
v₁ + v₂ = 190 --- (2)
Adding equations 1 and 2 we get
v₁ = 104 km/hr

[tex]\mathrm {I} =2\pi ^{2}\nu ^{2}\delta ^{2}\rho c[/tex]
Given is the sound intensity as measured in decibels and its measurement for a dishwasher is 37 decibels.
The given formula is -
db = 10 log(I/I₀)
Substituting the values, we get -
37 = 10 log(I/I₀)
log(I/I₀) = (37/10)
log(I/I₀) = (37/10)
(I/I₀) = e ^ (37/10)
I/I₀ = 40.44
