the midsegment of the trapezoid is RT. set up and equation and solve for x
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
x = 16
in the second drawing
x = 15 + (15 - 8) = 15 + 7 = 22

The length of QR(x) from the given figure is 4 units.
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.

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°
a class has five students what is the probability that four of the students were born on a weekday
Answer:
0.3718688642
Step-by-step explanation:
Weekdays consist of 5 days and weekends consists of 2 days. ... In case if you do not know, there are 7 days in a week.
The probability of one student who were born on a weekday
= 5/7
The probability of one student who were born on a weekend
= 2/7
This question then can be solved by using the binomial distribution formula,
[tex]P(X = 4) = \binom{5}{4} { (\frac{5}{7}) }^{4} {( \frac{2}{7}) }^{1} \\ = 0.3718688642 [/tex]

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.
The areas in Step 4 should be multiplied instead of added.

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.

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]

It is true that based on the given information triangle RST is similar to triangle UVW by the AA similarity postulate.
What are Similar triangles?Similar triangles are triangles that have the same shape but are different in size. More specifically, two triangles are similar if their corresponding angles are congruent and their corresponding sides are in proportion.
Here,
Since a figure is given with two triangles, RST and UVW.
From the figure, we can see that there are two angles that are equal, are given as;
∠R=∠U [measure is 67°]
∠T=∠W [measure is 90°]
