Answer:

  9 weeks

Step-by-step explanation:

In problems of this nature, the usual assumption is that the time required is proportional to the work product and inversely proportional to the number of people doing the job. Here, there is no change in the amount of work, but the number of people is reduced by a factor of 12/18 = 2/3.

So, the amount of time required is expected to increase by a factor of 1/(2/3) = 3/2.

  (6 weeks)×(3/2) = 9 weeks

It would have taken 9 weeks to sew the 540 dresses.

Answer:

D. b = 3

Step-by-step explanation:

Given the following data;

Points on x-axis (x1, x2) = 10, 12

Points on y-axis (y1, y2) = 23, 27

First of all, we would determine the slope.

Mathematically, slope is given by the formula;

[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]

[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

Substituting into the equation, we have;

[tex] Slope, m = \frac {27 - 23}{12 - 10} [/tex]

[tex] Slope, m = \frac {4}{2} [/tex]

Slope, m = 2

The equation of straight line is y = mx + b

Where;

m is the slope.

x and y are the points

b is the intercept.

To find the intercept, we would use the following formula;

y - y1 = m(x - x1)

Substituting into the formula, we have;

y - 23 = 2(x - 10)

y - 23 = 2x - 20

y = 2x - 20 + 23

y = 2x + 3 = mx + b

Therefore, intercept, b = 3

Answer:

C

Step-by-step explanation:

Answer:

Step-by-step explanation:

we have several angles that have the same vertex and so they are congruent

1) e = 35 degrees because the opp angle has this measure

2) d = 109 degrees for the reason above

3) for find f we have to notice that the sum of the three angles (if you look at the vertical line you can notice that it is a straight line, so describes two angles whose measures are 180 degrees)

f = 180 - (35 + 109)

f = 180 - 144 = 36 degrees

Answer:

Use the law of cosines to find c:

Use the low of sines to find one of the missing angles:

Find the missing angle:

Answer:

c ≈ 6.49

A ≈ 17.9°

B ≈ 67.1°

Step-by-step explanation:

To find the length of side c, use the Cosine rule.

Cosine rule

[tex]\sf c^2=a^2+b^2-2ab \cos C[/tex]

(where a, b and c are the sides and C is the angle opposite side c)

From inspection of the given triangle:

Substitute the given values into the formula and solve for c:

[tex]\implies \sf c^2=2^2+6^2-2(2)(6) \cos 95^{\circ}[/tex]

[tex]\implies \sf c^2=4+36-24 \cos 95^{\circ}[/tex]

[tex]\implies \sf c=\sqrt{40-24 \cos 95^{\circ}}[/tex]

[tex]\implies \sf c=6.49\:\:(2\:d.p.)[/tex]

To find angles A and B, use the Sine Rule.

Sine Rule

[tex]\sf \dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}[/tex]

(where A, B and C are the angles and a, b and c are the sides opposite the angles)

From inspection of the given triangle:

Substitute the given values into the formula:

[tex]\implies \sf \dfrac{\sin A}{2}=\dfrac{\sin B}{6}=\dfrac{\sin 95^{\circ}}{\sqrt{40-24 \cos 95^{\circ}}}[/tex]

Solving for A:

[tex]\implies \sf \dfrac{\sin A}{2}=\dfrac{\sin 95^{\circ}}{\sqrt{40-24 \cos 95^{\circ}}}[/tex]

[tex]\implies \sf A=\sin^{-1}\left(\dfrac{2\sin 95^{\circ}}{\sqrt{40-24 \cos 95^{\circ}}}\right)[/tex]

[tex]\implies \sf A=17.9^{\circ}\:\:(1\:d.p.)[/tex]

Solving for B:

[tex]\implies \sf \dfrac{\sin B}{6}=\dfrac{\sin 95^{\circ}}{\sqrt{40-24 \cos 95^{\circ}}}[/tex]

[tex]\implies \sf B=\sin^{-1}\left(\dfrac{6\sin 95^{\circ}}{\sqrt{40-24 \cos 95^{\circ}}}\right)[/tex]

[tex]\implies \sf B=67.1^{\circ}\:\:(1\:d.p.)[/tex]

Answer: Y=-5x+3

Step-by-step explanation:

first slope= 0 on the x axis so -2-3=-5

to get 3 you can do 4-1=3 or 7-4 or even 1-(-2)!

Correct answer: [tex]y = 3x -5[/tex]

You don't have to use the whole table in order to find equation. You can use just two points on the table to start.

In order to find the slope, the formula for that is: [tex]\frac{y_{2}-y_{1}}{x_{2} - x_{1}}[/tex]. So, we can start with points (1, -2) and (2, 1). Label (1, -2) as [tex]x_{1}[/tex] and [tex]y_{1}[/tex]; label (2, 1) as [tex]x_{2}[/tex] and [tex]y_{2}[/tex]. Now we can plug the numbers into the formula.

[tex]\frac{1-(-2)}{2 - 1}[/tex] → [tex]\frac{3}{1}[/tex] → [tex]3[/tex] is the slope.

To find the y-intercept, substitute (1, -2) into [tex]y = 3x + b[/tex].

[tex](-2) = 3(1) + b[/tex]

[tex]-2 = 3 + b[/tex]

[tex]-3[/tex]   [tex]-3[/tex]

________

[tex]b = -5[/tex] is the y-intercept.

Thus, the slope-intercept equation is [tex]y = 3x -5[/tex]. Hope this helps :) Let me know if you have any other questions related to this problem!

Answer:

50 feet

Step-by-step explanation:

Set up a 3-dimensional coordinate system (see the attached image).

This setup shows an axis that runs North-South (South is negative, North is positive), an axis that runs East-West (East is positive, West is negative), and an axis that runs Up-Down (Up is positive, Down is negative).

The two points in question are then:

First person's location (12, -20, -12), and the second person's location is (-20, 10, 12).

The distance between two points  [tex]\left( x_1,\,y_1,\,z_1\right)[/tex]  and  [tex]\left( x_2,\,y_2,\,z_2\right)[/tex] is

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2[/tex]

[tex]d=\sqrt{(-20-12)^2+(10-(-20))^2+(12-(-12))^2}\\\\d=\sqrt{(-32)^2+30^2+24^2}\\\\d=\sqrt{2500}\\\\d=50[/tex]

Answer:

6⅓ ft²

Step-by-step explanation:

Area of the figure = area of a trapezoid

= ½(a + b)h

Where,

a = 11⅓ft = 34/3 ft

b = 34/3 + 15/2 = (68 + 45)/6 = 113/6 ft

h = 6 ft

Plug in the values

Area = ½(34/3 + 113/6)*6

= (34/3 + 113/6)*3

= (68 + 113)/3

= 181/3

= 6⅓ ft²

Answer:

V=51, U=90 W= 39

Step-by-step explanation:

V= 51 Degrees (has told in the question)

U= 90 Degrees (Its A Right Angel Triangle, And Right Angle Is Always 90 Degrees)

W= 39 Degrees (Sum Of All Sides Of A Triangle = 180 Degrees

                           51 + 90 + W = 180

                           141 + W = 180

Answer:

A

Step-by-step explanation:

Equation A is true for all real numbers.  It says the quantity b + 2 is equal to itself!

Equation B, solved for b, gives b = 1, so the equation is true only for b = 1.

Equation C, solved for b, gives 2 = -2, which is absolutely false, so the equation has no solutions.

Equation D, solved for b, gives b = 1, so only one solution
