Answer:
[tex]\frac{3}{35}[/tex]
Start with 1/5 × 4/7[tex]\frac{1}{5} *\frac{4}{7} = \frac{1 * 4}{5 * 7} = \frac{4}{35}[/tex]
Preserve [tex]\frac{4}{35}[/tex] as x, it will be of good use in just a moment.[tex]\frac{4}{35} = x[/tex]
Multiply x([tex]\frac{4}{35}[/tex]) by [tex]\frac{3}{4}[/tex][tex]x * \frac{3}{4}[/tex]
To do this, you have to substitute the numerator(4) as x, and the denominator(35) as y.[tex]\frac{x(4) * 3}{y(35) * 4} = \frac{12}{140}[/tex]
Simplify using the LCD Least Common Denominator.[tex]\frac{12 / 4}{140 / 4} = \frac{3}{35}[/tex]

And with that information, your final answer is [tex]\frac{3}{35}[/tex]

The seasonal demand for a particular product is given below: Period 1 2 3 4 5 6 Demand 300 450 100 450 450 100 The fixed parameters are: Fixed Cost $8 Unit Production Cost $1 Holding Cost $ 1.3 Calculate total ordering cost using following three methods: i) Lot-for-Lot ii) Wagner-Whitin algorithm iii) Fixed order quantity
The ordering cost using the Lot-for-Lot method is 900.06.
How to calculate the cost?The ordering cost using the Lot-for-Lot method will be calculated thus:
C = Q/2(H) + D)Q(S)
C = 450/2(4) + 100/450(3)
C = 450(2) + 30/45
C = 900 + 0.7
C = 900.7
The ordering cost using Wagner-Whitin algorithm will be:
= 300 + 900 + 300 + 1700 + 2150 + 600
= 5750
The ordering cost using fixed order quantity will be:
= 6/(300 + 450 + 100 + 450 + 450 + 100)
= 6/1850
= 0.00324

can anyone help me find x, please?
Answer:
86°
Step-by-step explanation:
Two sides of the triangle are equal
=> ∠A = ∠C
And since ∠A = 47°
=> ∠C = 47° & ∠B = x°
Now, according to Angle sum property of a triangle
=> ∠A + ∠B + ∠C = 180°
=> 47° + x + 47° = 180°
=> 94° + x = 180°
=> x = 180 - 94 = 86°
Therefore x = 86°

Which of the following logarithmic equations is equivalent to the exponential
equation below?
e^x = 15.29
Answer:
Step-by-step explanation:
Natural log and the number 'e' are inverse to each other. Therefore, if you take the natural log of both sides, the exponential cancels and leaves 'x' isolated:
[tex]ln(e^x)=ln(15.29)[/tex]
[tex]x=ln(15.29)[/tex]
Let's solve for x
e^x=15.29So natural logarithm on both sides
[tex]\\ \rm\Rrightarrow x=ln(15.29)[/tex]

Given the vector field F= ∆(x3 + y3 + z3 + 3xyz), find div F and curl F.
Since F is apparently a vector field, I assume you mean
[tex]\vec F = \nabla(x^3+y^3+z^3+3xyz)[/tex]
with ∇ = gradient, whereas ∆ is often used to denote the Laplacian, ∆ = ∂²/∂x² + ∂²/∂y² + ∂²/∂z².
Let [tex]f(x,y,z)=x^3+y^3+z^3+3xyz[/tex]. Compute the gradient of f :
[tex]\vec F = \nabla f(x,y,z) = \dfrac{\partial f}{\partial x} \, \vec\imath + \dfrac{\partial f}{\partial y} \, \vec\jmath + \dfrac{\partial f}{\partial z} \, \vec k[/tex]
[tex]\vec F = (3x^2+3yz) \,\vec\imath + (3y^2 + 3xz) \,\vec\jmath + (3z^2+3xy) \,\vec k[/tex]
Now compute the divergence of F (incidentally, divergence of a gradient field is the Laplacian of the f):
[tex]\mathrm{div} \, \vec F = \dfrac{\partial(3x^2+3yz)}{\partial x} + \dfrac{\partial(3y^2+3xz)}{\partial y} + \dfrac{\partial(3z^2+3xy)}{\partial z}[/tex]
[tex]\boxed{\mathrm{div} \, \vec F = 6x + 6y + 6z}[/tex]
and the curl: (the following is overkill, since any gradient field has curl zero, but it doesn't hurt to verify that)
[tex]\mathrm{curl}\, \vec F = \left(\dfrac{\partial(3z^2+3xy)}{\partial y} - \dfrac{\partial(3y^2+3xz)}{\partial z}\right) \,\vec\imath - \left(\dfrac{\partial(3z^2+3xy)}{\partial x} - \dfrac{\partial(3x^2+3yz)}{\partial z}\right) \, \vec\jmath \\ ~~~~~~~~~~~~ + \left(\dfrac{\partial(3y^2+3xz)}{\partial x} - \dfrac{\partial(3x^2+3yz)}{\partial y}\right) \,\vec k[/tex]
[tex]\boxed{\mathrm{curl} \,\vec F = \vec 0}[/tex]

What are trigonometric ratios?The sides and angles of a right-angled triangle are dealt with in Trigonometry. The ratios of acute angles are called trigonometric ratios of angles. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
From the given figure, QR=x, RS=2√3 units and ∠STR=60°.
We know that, sinθ= Opposite/Hypotenuse
sin60°=2√3/RT
√3/2=2√3/RT
RT=4 units
As we know, tanθ= Opposite/Adjacent
tan45°= x/4
1= x/4
x=4 units
Therefore, the length of QR(x) from the given figure is 4 units.

Layla is determining the area of the trapezoid. Her work is shown below.
A trapezoid has a base of 14 feet, height of 10 feet, and top side length of 8 feet.
Step 1: Break the figure into rectangles and triangles.
A trapezoid is broken into a triangle and rectangle. The rectangle has a base of 10 feet and a height of 8 feet. The triangle has a base of 10 feet and a height of 6 feet.
Step 2: Find the area of the rectangle: 8 times 10 = 80.
Step 3: Find the area of the triangle: One-half times 6 times 8 = 24.
Step 4: Add the areas together: 80 + 24 = 104 square feet.
Which best describes Layla’s error?
The height of the triangle in Step 1 should be 4 ft.
The area of the triangle in Step 3 should be One-half times 6 times 10 = 30.
The area of the triangle is Step 3 should be halved because there is only one triangle.

Step-by-step explanation:
Anny is not a very good driver, so she drives really slow. She normally drives at a speed of 50 miles per hour if it is not raining, and 30 miles per hour if it is raining. Today she drove in the sun in the morning and in the rain in the afternoon, for a total of 120 miles in 180 minutes. How many minutes did she drive in the rain?
Answer:
9.1s
Step-by-step explanation:
Since we know that velocity is uniformly decelerating, we can take the average velocity: Letting Vf equale 0 /ms, we get 1/2 21.8ms or 10.9ms. Now we know V = D/T and rearranging this gives T = D/V. Substitute our velocity of 10.9m/s for V and 99m for D: T = 99m/ 10.9ms. finally we get T = 9.1s
Hope This Helps :)
The time in which Anny drives in the rain is 90 minutes. This is calculated by using the speed-distance-time formula.
Relationship between distance, time, and speed:Speed is the ratio of distance traveled to the time taken for traveling.
Speed=distance/time
Unit: m/s
Given data:It is given that,
Anny drives at a speed of 50 miles per hour if it is not raining and drives at a speed of 30 miles per hour.
Today she drove in the sun in the morning and the rain in the afternoon, for a total of 120 miles in 180 minutes.
Calculation:Consider x be the time required to drive not in the rain and y be the time required to drive in the rain
So, the distance covered (not in the rain) = 50x (since the speed is 50 mile/h), and the distance covered (in the rain) =30y (since the speed is 30 miles/h)
Therefore, the total distance covered both in rain and without rain is:
50x+30y=120 (since the total distance she drove is 120 miles)
And the total time required for driving in rain and without rain is:
x + y=3 (since 180 minute = 3 hours)
On solving the above equations we get,
x=[tex]\frac{3}{2}[/tex] and y=[tex]\frac{3}{2}[/tex]
Then,
y=[tex]\frac{3}{2}[/tex]×60(minute)=90 minute
Therefore, the time taken for her to drive in rain is 90 minutes.

95%
Answer:
It's D) 95%
Step-by-step explanation:
It's the correct answer
The percentage of the times are between 2 hours and 4 hours is 45.5%.
What is standard deviation?Standard deviation is the positive square root of the variance. Standard deviation is one of the basic methods of statistical analysis. Standard deviation is commonly abbreviated as SD and denoted by 'σ’ and it tells about the value that how much it has deviated from the mean value.
Given that, μ=3 hour, σ=0.5 and x1=2 hours and x2=4 hours.
We know that, Z=(x-μ)/σ
Here, Z1=(2-3)/0.5
Z1=-2 = -0.2275
Z2=(4-3)/0.5
Z2=2 = 0.2275
= 0.2275-(-0.2275)
= 0.2275+0.2275
= 0.455
= 45.5%
Therefore, the percentage of the times are between 2 hours and 4 hours is 45.5%.

Step-by-step explanation:
since it is the midsegment, all involved and related line segments follow the 1/2 factor.
so, the length of the midsegment is precisely in the middle between the lengths of the top and bottom lines.
in the first drawing
22 = x + (x - 10)
22 = x + x - 10
32 = x + x = 2x
