To a box that contained 30 pencils 10 out of which were red several more non-red pencils were added. Now 25% of all pencils in t

Anastasy [175]

Answer:

The Amount of Non-red pencil which were added to the box = 10

Step-by-step explanation:

Given as :

The number of pencils in a box = 30

The number of red pencils in a box out of 30 = 10

So , the number of Non-red pencils = 30 - 10 = 20

Again let the number of Non-red pencils which added further = x

So, now the amount of total pencil get increase to (30+x)

Among (30+x) pencils in box,25% of them are red ,

I.e The number of red pencils in a box out of (30+x) = 25% of (30+x)

And the number of Non-red pencils = 20 + x

SO, according to question

25% of (30+x) + (20+x) = (30+x)

Or, (20+x) = (30+x) - (25% of (30+x))

Or, 20+x = (30+x) [ 1 -( $\frac{25}{100}$ ]

Or, 20+x = (30+x) ( $\frac{3}{4}$

Or, 80+4x = 90+3x

or 4x - 3x = 90-80

Or, x = 10

Hence the number of Non-Red pencils in the box which added further = 10 Answer

Answer:

$\boxed{x^4 + x^2 + x}$

Step-by-step explanation:

$\frac{x^5 - x^4 + x^3 -x^2 + x - 1}{x - 1}$

$= \frac{(x - 1)(x^4 + x^2 + x)}{x - 1}$

$= x^4 + x^2 + x$

Happy to help :)

The number of employees for a certain company has been decreasing each year by 2%. If the company currently has 690 employees an

solmaris [256]

Answer:

511 employees

Step-by-step explanation:

Given data

P=690

rate= 2%

time = 13 years

let us apply the simple interest formula

A=P(1-rt)

Note the negative sign (since we are dealing with decrease)

A= 690(1-0.02*13)

A=690(1-0.26)

A=690*0.74

A=510.6

A= 511 approx

Hence the population will reduce to 511 employees
