Answer:

Velocity of plane is 100 mi/hr along northeast direction

Step-by-step explanation:

From the question it is given that Initial velocity of plane is 150 mi/hr along east north direction and wind is blowing at 50 mi/hr along southwest direction

since the velocity of wind and plane is exactly opposite

⇒ relative velocity of plane with respect to wind is given by

[tex]v_r_e_l = v_p - v_w[/tex] where [tex]v_p[/tex] is the velocity of plane = 150mi/hr and [tex]v_w[/tex] = velocity of wind = 50 mi/hr

Therefore, [tex]v_r_e_l = v_p - v_w[/tex]  = [tex]v_r_e_l = 150 - 50 = 100 mi/hr[/tex] alond northwest direction

Therefore, velocity of plane is 100 mi/hr along northeast direction

By working with the velocity vectors, we will find that the direction of motion of the plane is 28.7 south of east.

First, we need to define our coordinate axis, I will define the x-axis as the east and the y-axis as the north.

We know that the plane travels at 150 mi/hr at 100° east of north, notice that if we measure from the positive x-axis, this is equivalent to an angle of -10°.

So the vector is:

V =  < 147.7 mi/hr,  -26 mi/hr >

Now we know that the wind blowing at 50mi/hr at southwest, exactly southwest would be at an angle of 225°, so the components of the vector are:

So the vector is:

W = < -35.4 mi/hr, -35.4 mi/hr>

The sum of the vectors gives the total velocity of the plane in the wind, we will get:

V + W =  < 147.7 mi/hr -35.4 mi/hr ,  -26 mi/hr -35.4 mi/hr >

V + W =  <112.3 mi/hr, -61.4 mi/hr>

The direction of a vector <x, y> is given by:

θ = Atan(y/x)

Then in this case the direction of the plane is:

θ = Atan(-61.4 mi/hr/112.3 mi/hr) = -28.7°

So the direction of the plane is 28.7° south of east.

Answer:

See Explanation

Step-by-step explanation:

Both vertical lines are parallel to each other. (given)

Similarly, both horizontal lines are also parallel to each other.. (given)

So, quadrilateral obtained by the intersection of both vertical and horizontal lines is a rectangle.

Therefore,

Answer For the question:

8

Answer: -1/8

Step-by-step explanation:

3/4 + -3/8 + -1/4

Find the LCM of 4, 8, and 4

That's 8 so you make an equivalent fraction for all fractions so the denominator is 8.

3/4 = 6/8

-3/8 = -3/8

-1/4 = -4/8

Now the expression looks like this:

6/8 + - 3/8 + -4/8

6/8 - 3/8 - 4/8

6/8 - 7/8

-1/8

Answer:

y=124°

x=67°

Step-by-step explanation:

For the triangle on the right

180-74-50=56°

then y= 180-56=124°

For the triangle on the middle (that small triangle)

180-85(Head opposite angles)-50=45°

So

x=180-45-68=67°

Step-by-step explanation:

solution

let,A(5,-1)

given

y=12x-1

or, y = 12 × x + (-1)

comparing it with y=mx+c

we get

x=1

y = c = -1

now

A(5,-1) and B(1,-1)

equation of line is,

(y-y1)/(x-x1) = (y2-y1)/(x2-x1)

or, (y+1)/(x-5) = (-1+1)/(1-5)

or, (y+1)/(x-5) = 0/-4

cross multiply

-4y-4 = 0

or, 0=4y+4

or, 4y+4=0 is the required eqn

I think this is the process and answer too.

I hope this helps you

Answer: 2 Vats will be used

Step-by-step explanation:

using the formula below, the ideal number of Kanban cards can be calculated;

N = (DT × ( 1 + X)) / C

where N is total number of container,

D is panned usage rate of using work Centre

T is Average waiting time for replenishment of parts plus average production for a  container of parts,

X is policy variable set by management that reflects possible inefficiency in the system ,

C is capacity of standard container.

Now, in the question, we were given that;

D = 204 pounds per day  = 204 / 8hrs = 25.5 pounds/hr   { The plant operates on an eight-hour day}

T = 2.25 hrs

X = 0.17

C = 34 pounds each

we substitute

N = (25.5×2.25 × ( 1 + 0.17)) / 34  

N = 67.12876 / 34

N = 1.974375 ≈ 2 Vats

Therefore 2 Vats will be used.

<R = 47 degrees

<S = 47 degrees

<T = 86 degrees

Step-by-step explanation:

The sum of angles in a triangle is 180degrees

Given triangle RST

<R + <S + <T = 180

9x + 2 + 13x - 18 + 17x +1 = 180

39x - 15 = 180

39x = 180 + 15

39x = 195

x = 195/39

x = 5

Get <R

<R = 9x + 2

<R = 9(5) + 2

<R = 47 degrees

Get <S

<S = 13x-18

<S = 13(5) - 18

<S = 65-18

<S = 47 degrees

Get <T

<T = 17x + 1

<T = 17(5)+1

<T = 85+1

<T = 86 degrees
