Total cost: $900 + $3150 + $3200 = $7450
Moving Average Unit Cost:
June 1: $7450 / (150 + 450) = $7/unit (rounded to 3 decimal places)
June 12: $7450 / (150 + 450 + 400) = $7.36/unit (rounded to 3 decimal places)
June 15: $7450 / (150 + 450 + 400 + 500) = $7.51/unit (rounded to 3 decimal places)
June 23: $7450 / (150 + 450 + 400 + 500) = $7.51/unit (rounded to 3 decimal places)
June 27: $7450 / (150 + 450 + 400 + 500 + 420) = $7.43/unit (rounded to 3 decimal places)
Cost of ending inventory using perpetual inventory system:
FIFO: $7.51/unit * 80 units = $604 (rounded to 3 decimal places)
LIFO: $7/unit * 80 units = $560 (rounded to 3 decimal places)

m∠Y = 60°WY = 7 inStep-by-step explanation:
Given triangle WXY with sides WX = 7 in and XY = 7 in and angle X = 60°, you want the measure of angle Y and the length of side WY.
Isosceles triangleThe equal given side measures tell you that their opposite angles (W and Y) have equal values. Those values will be such that the total of all angles is 180°:
W +Y +X = 180°
Y +Y +60° = 180° . . . . . . . . . . . use given values; substitute Y for W
Y = (180° -60°)/2 = 60° . . . . . . . subtract 60°, divide by 2
All of the angles in this triangle have the same measure, so it is an equilateral triangle. All of the sides have the same measure, too.
angle Y = 60°
WY = 7 inches

The fact that 1 liter = 1.057 quarts can be written as the conversion factor
The conversion factor of litre to quarts is 1 litre = 1.057 quarts and its meaning is discussed below.
What is a conversion factor?
A conversion factor is a number that is used to multiply or divide one set of units into another. If a conversion is required, it must be done using the correct conversion factor to get an identical value. The correct conversion factor to convert minutes to hours is 60 minutes = 1 hour.
The metric unit of a volume known as the litre is mostly used to measure liquids.
An English measurement of volume equal to the one-quarter gallon is the quart. There are now three different types of quarts in use: the liquid quart, dry quart, and imperial quart of the British imperial system.
The standard value of converting liquid to quarts is 1 litre = 1.057 quarts.
This means that volume of 1 litre of a substance is equivalent to the volume of 1.057 quarts of the same substance.
Therefore the conversion factor of litre to quarts is 1 litre = 1.057 quarts.

Jimena finances a $4,200 furniture purchase. The store offers 3%
simple interest, and Jimena will pay off the balance in 6 months.
How much simple interest will Jimena pay the store?
Answer: To calculate the simple interest, you can use the formula:
I = Prt
where I is the interest, P is the principal (the amount borrowed), r is the interest rate as a decimal, and t is the time in years.
In this case, P = $4,200, r = 0.03, and t = 6/12 = 0.5 (since the interest is paid over 6 months, which is half of a year). Plugging these values into the formula, we get:
I = Prt = 4,200 * 0.03 * 0.5 = $63
So, Jimena will pay the store $63 in simple interest.

If we are to write the following polynomial in descending powers of the variable and with no missing powers 3x^3 -70, it would be 3x^3 - 70 + 0x^2 + 0x + 0
What is a Polynomial?A polynomial is an equation made up of coefficients and indeterminates that uses only the addition, subtraction, multiplication, and powers of positive-integer variables.
Hence, it can be seen that descending order is basically when the power of a term decreases for each succeeding term. For example, x3 + x2 + x or 2 x4 + 3 x2 + 7 x are arranged in descending order. Descending order is more commonly used.
The polynomial in descending powers of the variable with no missing powers is:
3x^3 - 70 = 3x^3 - 70 + 0x^2 + 0x^1 + 0x^0
= 3x^3 - 70 + 0x^2 + 0x + 0

A classic counting problem is to determine the number of different ways that the letters of "recommend " can be arranged.
The number of different ways that the letters of "recommend" can be arranged is 90720.
What is arrangement?
Generally speaking, an arrangement of objects is just a collection of them. A combination (order is ignored) or permutation is used to determine the number of "arrangements" of the components (order is significant). An arrangement is a group of hyperplanes that divides a space into cells.
If there are n different objects in the system then the number of different ways of arrangement of n objects is n!
If the repetition of the objects are allowed in the system the number of different ways of arrangement is -
n! / (no. of repetition of object 1)! .... (no. of repetition of object r)!
Total number of letters in the word "recommend is 9.
The number of different ways of arangement of the 9 letters is 91
The repetition of letter "e" is 2 and repetition of letter "m" is 2.
The number of different ways that the letters of "recommend" can be arranged is -
9! / 2! × 2!
(9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) / (2 × 1) × (2 × 1)
(9 × 8 × 7 × 6 × 5 × 3 × 2 × 1)

1. sin∠EDA is equal to sin∠EBC
2. sin∠CEB is not equal to sin∠EBC
3. cos∠BEC is equal to sin∠EBC
4. cos∠ADE is not equal to sin∠EBC
5. sin(90 - m∠EBC) is not equal to sin∠EBC
6. cos(90 - m∠EDA) is equal to sin∠EBC
Step-by-step explanation:
From inspection of the given diagram, ∠EAD = ∠ECB = 90°.
According to the vertical angles theorem, ∠BEC = ∠DEA.
According to AA similarity theorem, ΔADE ~ ΔCBE
Therefore, ∠EDA = ∠EBC.
This means that:
sin∠EDA is equal to sin∠EBCsin∠CEB is not equal to sin∠EBC[tex]\boxed{\begin{minipage}{9.4 cm}\underline{Trigonometric ratios} \\\\$\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}[/tex]
Since cos∠BEC = CE/BE and sin∠EBC = CE/BE then:
cos∠BEC is equal to sin∠EBC.As ∠BEC ≠ ∠ADE then:
cos∠ADE is not equal to sin∠EBC.As sin(90° - x) = cos(x) then sin(90 - m∠EBC) = cos∠EBC.
As cos∠EBC ≠ sin∠EBC then:
sin(90 - m∠EBC) is not equal to sin∠EBCAs cos(90° - x) = sin(x) then cos(90 - m∠EDA) = sin∠EDA.
As sin∠EDA = sin∠EBC then cos(90 - m∠EDA) = sin∠EBC.
Hence:
cos(90 - m∠EDA) is equal to sin∠EBC.Let f(x)=6x2+18x. Answer the following questions. 1. Find the x intercepts of the parabola. Intercepts (separate with commas): x=2. Find the vertex of the parabola. Write the vertex as a point (a,b) where a and b are numbers.
The x-intercept is -3 and the vertex of the parabola is (-1.5, -13.5).
What is vertex?The intersection of two lines, two line segments, or any other suitable arrangement of rays, segments, and lines that results in two straight "sides" coming together at one location is known as an angle's vertex.
The x coordinate of the vertex is given as:
x = -b/2a= -18/ 2(6)= - 1.5
The y coordinate of the vertex is given as:
y = f(- 1.5)
f(- 1.5) = 6(- 1.5)² + 18(- 1.5) = 13.5 - 27= -13.5
Hence, the vertex of the parabola is (-1.5, -13.5).
The x intercept is found by substituting the value of y = 0 in the function:
0 = 6x² + 18x
0 = 6x (x + 3)
x + 3 = 0
x = -3
Hence, the x-intercept is -3 and the vertex of the parabola is (-1.5, -13.5).

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Triangles PQR and ZQX are similar!
Square side => a
XZ / (PQ - PZ) = PR / PQ
a / (12 - a) = 8 / 12
a = 4.8
The side length of the square PZXY is sqrt(2).
What is a square?A square is a two-dimensional figure that has four sides and all four sides are equal.
The area of a square is given as side².
We have,
Since triangle PQR is a right triangle, we can use the Pythagorean theorem to find the length of QR:
QR² = PQ² + PR²
QR² = 1² + 1²
QR² = 2
QR = √2
Since PZXY is a square, its sides are equal in length.
Let's denote the length of one side of the square as s.
Then, we can write:
PR = PX + RX
1 = s + QY
Since QY = PZ = s and PX = QX = QR - QY = sqrt(2) - s,
we can substitute these values into the equation for PR to get:

Write the first five terms of the arithmetic sequence with the first term a1=7 and the common difference d=4
Answer:
7, 11, 15, 19, 23
Step-by-step explanation:
Since the common difference is 4 each successive term is 4 more than the previous term
If we let aₙ be the nth term,
a₁ = 7
a₂ = 7 + 4 = 11
a₃ = 11 + 4 = 15
a₄ = 15 + 4 = 19
a₅ = 19 + 4 =23
The first five terms are: 7, 11, 15, 19, 23
We can also use the generalized formula for the nth term:
aₙ = a₁ + d(n - 1)
where a₁ = first term
d = common difference
Plugging in the known values we get
aₙ = 7 + 4(n- 1)
aₙ = 7 + 4n - 4
aₙ = 3 + 4n
Substituting n = 1, 2, 3, 4, 5 into the above equation will yield the same values

vector a has a magnitude 5.00 and points in a direction 60.0degrees clockwise from the negative y axis. what are the x and y components of vector a.
A is directed along negative X and Y axes respectively having magnitudes 3.214 and 3.83 units respectively.
A vector is an object that, as we all know, possesses both magnitude and direction. We must determine a vector's length in order to determine its magnitude. Vector quantities include things like velocity, displacement, force, momentum, etc. However, scalar quantities like as speed, mass, distance, volume, temperature, etc. exist. In contrast to vectors, which
have both magnitude and direction, scalars only have magnitude.
Magnitude of vector A = |A| = 5 units
We know, the negative Y-axis is an angle of 270° counterclockwise with a positive X-axis.
θ = Angle of vector A with positive X-axis = (270° - 40°) = 230°
So, x component of vector A = Ax = |A| * cos 230° = |A| * cos (180° + 50°) = |A| * (- cos 50°) = 5 * (-0.6428) = -3.214
And, y component of vector A = Ay = |A| * sin 230° = |A| * sin (180° + 50°) = |A| * (- sin 50°) = 5 * (-0.766) = -3.83
Since Ax and Ay both are negative relative to positive X and Y axes respectively; so, the x and y components of vector A are directed along negative X and Y axes respectively having magnitudes 3.214 and 3.83 units respectively.

What are Parallel lines?Parallel lines are two or more lines in a coordinate plane that are equidistant from each other at all coordinates.
The given line can be rewritten in slope-intercept form as y=(5/8)x+(3/4), where the slope is 5/8. So, any parallel line will also have a slope of 5/8.
Using the point-slope form of a line, we can write the equation of the line as:
y - (-4) = (5/8)(x - 4)
Simplifying, we get:
y = (5/8)x - 23/8
Therefore, the equation of the line that is parallel to 5x-8y=-6 and passes through (4,-4) is y = (5/8)x - 23/8.
The slope of the given line is 5/8, so the slope of any line perpendicular to it will be -8/5.
y - (-4) = (-8/5)(x - 4)
Simplifying, we get:
y = (-8/5)x + 16/5
Therefore, the equation of the line that is perpendicular to 5x-8y=-6 and passes through (4,-4) is y = (-8/5)x + 16/5.

Suppose that a particle moving along the x-axis encounters a resisting force that results in an acceleration of a =-=-0.10 V v. Given that x = 0 cm and v = 36 cm/s at time t = 0, find the velocity v and position x as a function of t for t 2 0. v= 2 cm/s Edit C x= 2 cm
The velocity of the particle v as a function of time t is given by v(t) = 36 - 0.10 * t^2 cm/s and the position x as a function of time t is given by x(t) = 36 * t - 0.05 * t^3 cm.
The problem states that at time t = 0, the particle has an initial velocity of v = 36 cm/s and is located at x = 0 cm. The particle is accelerating with a=-0.10 V v. This means that the velocity of the particle is changing by -0.10 V v each second. This can be expressed in terms of the time t as v(t) = 36 - 0.10 * t^2 cm/s. The position of the particle at any time t can be expressed as x(t) = x0 + v0 * t + 1/2 * a * t^2, where x0 is the initial position and v0 is the initial velocity. In this case, x0 = 0 and v0 = 36, so the position of the particle at any time t can be expressed as x(t) = 36 * t - 0.05 * t^3 cm. This means that the particle will move away from the origin (x=0) and its velocity will decrease each second.
