$\\ \tt\longmapsto 9(a+11)$

Apply distributive law

a(b+c)=ab+ac

$\\ \tt\longmapsto 9a+9(11)$

$\\ \tt\longmapsto 9a+99$

A company has 29900 employees in one country. If this represent 18.3% of the company’s employees, how many employees does it hav

mario62 [17]

Answer:

About 163 388 employees

Step-by-step explanation:

Let total number of employees in the company be represented by x. Thus:

$18.3\% \: of \: x = 29900$

$18.3\% \:x \: = 29900$

$\frac{18.3}{100}x = 29900$

$0.183x = 29900$

Divide through by 0.183

$\frac{0.183x}{0.183} = \frac{29900}{0.183}$

$x = 163387.9$

$x = 163388 \: to \: nearest \: whole \: number$

The total number of employees in one country is about 163388

If the parallel sides of a trapezoid are contained by the lines and , find the equation of the line that contains the midsegment

Fittoniya [83]

Answer:

Equation of midsegment line: y = (-1/4)x + 2.

Step-by-step explanation:

If the parallel sides of a trapezoid are contained by the lines:-

y = (-1/4)x +5 and y = (-1/4)x - 1

Midsegment of any trapezoid is the line segment

1. that is parallel to pair of parallel side of trapezoid and

2. that passes through the middle of the trapezoid and cuts the other two sides into equal-half.

It means the midsegment would have same slope as the parallel lines and y-intercept would be in the middle of intercepts of parallel lines.

So y = mx + b

where m = -1/4 and b = (5 - 1)/2 = 4/2 = 2.

Hence, the equation of midsegment would be y = (-1/4)x + 2.

84% 84, percent of astrid's books are fiction. What fraction of astrid's books are fiction?

yuradex [85]

Let number of books by astrid's = x

Out of x , 84% are fiction.

So, Number of non fictional books = x - $\frac{84x}{100}$

= $\frac{100x- 84 x}{100} = \frac{16x}{100}$

→Ratio of number of books to fictional books

$=\frac{x}{\frac{84x}{100}}\\ = \frac{100}{84}\\= \frac{25}{21}$ ⇒[Dividing numerator and denominator by 4.]

→Out of 25 books by astrid 21 are fictional.

→ Number of fictional books by astrid = $\frac{21}{25}$

Given the function f(x) = 2|x + 6| – 4, for what values of x is f(x) = 6?

lara [203]

Answer:

x = -1 , - 11,

Step-by-step explanation:

| x | = x

|- x | = x

f(x) = 2 | x + 6 | - 4

x = - 1 , f( - 1) = 2 | - 1 + 6 | - 4 = 2 | 5 | - 4 = 10 - 4 = 6 , True

x = 1 , f( 1 ) = 2 | 1 + 6 | - 4 = 2 | 7 | - 4 = 14 - 4 = 10 , False

x = 11, f( 11 ) = 2 | 11 + 6 | - 4 = 2 | 17 | - 4 = 34 - 4 = 30 , False

x = - 11, f( - 11) = 2 | -11 + 6 | - 4 = 2 | - 5 | - 4 = 10 - 4 = 6 , True

x = 14 , f( 14 ) = 2 | 14 + 6 | - 4 = 2 | 20 | - 4 = 40 - 4 = 36 , False

x = -14 , f( - 14 ) = 2 | - 14 + 6 | - 4 = 2 | - 8 | - 4 = 16 - 4 = 12 , False

x = - 26 , f( - 26) = 2 | -26 + 6 | - 4 = 2 | -20 | - 4 = 40 - 4 = 36 , False

x = 26, f( 26 ) = 2 | 26 + 6 | - 4 = 2 | 32 | - 4 = 64 - 4 = 60 , False

Given f ( x ) = 6

f( x ) = 2 | x + 6 | - 4

6 = 2 | x + 6 | - 4

6 + 4 = 2 | x + 6| - 4 + 4 [ adding 4 to both sides ]

10 = 2 | x + 6 | + 0

5 = | x + 6 | [ dividing both sides by 2 ]

$- 5 =\ ( x+ 6) \ = 5\\\\$ $[ \ | x | = a\ => \ -a \ = x \ = a \ ]$

$- 5 - 6 = \ x + 6 - 6 \ = \ 5 - 6\\$ $[ \ subtracting \ by \ 6 \ ]$

$-11 = \ x \ = - 1$
