There are approximately 4.3 weeks in each month. How much will you take home each month after taxes?​
Marianna [84]

Answer:

So roughly c x c = b/100

5 x 5 x 100 = $2500

Step-by-step explanation:

Lets say c = 5 and b = 1

= 5c =100c/5c x b

= 20c x b

We can also show

= 20c x b =5c

c = 20c/5c x b = 5c

1/20 x 5c = 5c

b=1

One example is 20%  = 0.20 x 500 = 100c  

=  7.12c  = 7c

1= 100%

100 x 71.042  = 710.42 weekly pay. emergency tax 142 = 568

100 x 71.042 = 710.42 weekly pay, normal tax 15% 142.084 =107

710-107 = 603 a week

4.3/7 x 603/7 = 86.1428571429 x 30 = 2584.29

jok3333 [9.3K]

Answer:

Step-by-step explanation:

the  expression could help you find the distance between A(x; y) and B(x',y')is:

AB = √((x-x')²+(y-y')²)

in this exercise  :  x = 10

                             x' = - 6

                              y =4

                             y' = 4

Find the least common multiple of each pair of polynomials.<br> 5 y² - 80 and y + 4
kobusy [5.1K]

The least common multiple of each pair of the polynomial (5y² - 80) and

(y + 4) is equal to 5(y-4)(y+4).

As given in the question,

Given pair of the polynomial is (5y² - 80) and (y + 4)

Simplify the given polynomial using (a² -b²) = (a-b)(a +b)

(5y² - 80) = 5(y² -16)

⇒(5y² - 80) = 5(y² - 4²)

⇒(5y² - 80) = 5(y -4)(y + 4)

And  (y + 4) = (1) (y+4)

Least common multiple = 5(y-4)(y+ 4)

Therefore, the least common multiple of the given pair of the polynomial is 5(y -4)(y+ 4).

You order a new pair of running shoes from a website that offers free shipping on orders of $75 or more. Your shoes cost $69.95.
gayaneshka [121]

Answer: x > 75-69.95; you need five dollars and five cents more for free shipping ($5.05)

Step-by-step explanation: i believe this is the correct answer because as long as you have 75 dollars or more, then you will be good so that’s how i got the inequality. to find this you just subtract the amount needed (75) by the amount you have and you get your answer. oh and to be clear x represents the amount needed for free shipping. i am not sure if i understood the problem correctly so i apologize if it is incorrect. i hope this helped and good luck!
