Novay_Z [31]

The number of ways that the company can choose four workers is 40920 ways.

<h3>How to calculate the number?</h3>

From the information, the building company employs 3 laborers 12 joiners 8 electrician 4 plumbers. The total number of workers will be:

= 3 + 12 + 8 + 4

= 27 workers

It should be noted that combination will be used to choose the 4 workers. This is illustrated as

Combination formula

ⁿCr = n! / ((n – r)! r!)

n = the number of items.

r = how many items are taken at a time.

where n = 33

r = 4

ⁿCr = n! / ((n – r)! r!)

³³C₄ = 33! / (33 - 4)! 4!

= 33! / 29! 4!

= 33 × 32 × 31 × 30 / 4 × 3 × 2

= 40920 ways

What is the equation of the line passing through the points (Two-fifths, StartFraction 19 Over 20 EndFraction)and (one-third,

Vinil7 [7]

<h3>4x - 8y = -6 is the equation of line in standard form</h3>

Solution:

The equation of line in point slope form is given as:

$y - y_1 = m(x-x_1)$

Where, m is the slope of line

The slope of line is given as:

$m = \frac{y_2-y_1}{x_2-x_1}$

From given,

$(x_1, y_1) = (\frac{2}{5} , \frac{19}{20})\\\\(x_2, y_2) = (\frac{1}{3} , \frac{11}{12})$

Substituting the values we get,

$m = \frac{\frac{11}{12} - \frac{19}{20}}{\frac{1}{3} - \frac{2}{5}}\\\\Simplify\\\\m = \frac{-8}{240} \times \frac{15}{-1}\\\\ m = \frac{120}{240}\\\\m = \frac{1}{2}$

$\text{Substitute } m = \frac{1}{2} \text{ and } (x_1, y_1) = (\frac{2}{5} , \frac{19}{20}) \text{ in eqn 1 }$

$y - \frac{19}{20} = \frac{1}{2}(x - \frac{2}{5})\\\\y - \frac{19}{20} = \frac{x}{2} - \frac{1}{5}\\\\\frac{x}{2} - y = - \frac{19}{20} + \frac{1}{5}\\\\\frac{x}{2} - y = \frac{-15}{20}\\\\Simplify\\\\y = \frac{1}{2}x + \frac{3}{4}$

In standard form,

$y = \frac{4x+6}{8}\\\\8y = 4x + 6\\\\4x - 8y = -6$

Thus the equation of line is found

Ilya [14]

Answer:

first he had M some unknown amount

then he had 2/3 M since he spent 1/3 M

then he spent 3/4 of the (2/3 M) so he had 1/4 of the ( 2/3M)

then he spent what was left $20 so $20 = 1/4 ( 2/3 M) now solve for M

and check by doing each step and figuring how much was spent and how much left.

another method 

let us consider the left amount be Y and total now of M dollar be X

then

Y = amount of money Nartin has left

Y = X - ( 1/3 ) ( X ) - ( 3/4 ) ( X - 1/3 X ) - 20

Y = X - 1/3 X - 3/4 X + 3/12 X - 20

Y = X - 4/12 X - 9/12 X + 3/12 X - 20

Y = X - 10/12 X - 20

Y = X - 5/6 X - 20

Y = ( 1 / 6 ) ( X ) - 20

hope it helped u buddy : )
