Write two different expressions to represent the sale price of a fishing pole, f, after a 20% discount.
Rom4ik [11]

Answer:

When we have a discount of X% of the original price, the new price is calculated as:

New price = (original price) - (original price)*(X%/100%)

In our case, let's define:

P = original price of the fishing pole

f = price of the fishing pole after the discount

X% = 20%

Then the equation for the price of the fishing pole is:

f = P - P*(20%/100%) = P - P*0.2 = P*(1 - 0.2) = P*0.8

f = 0.8*P

This means that the price after the discount is 0.8 times the original price.

Find the quotient and any excluded values.<br><br> (x + 5/x^2 + 9x + 20)/(x^2-16/x-4)
Wittaler [7]
By  <span>(x + 5/x^2 + 9x + 20) you apparently meant the following:

         x+5
 ----------------------
   x^2 + 9x + 20

and by 

</span><span>(x^2-16/x-4)
                                       x^2-16
you apparently meant ---------------
                                         x - 4

Please use additional parentheses for clarity.

Dividing,

</span>         x+5                   (x-4)(x+4)
 ----------------------  *  ---------------
   x^2 + 9x + 20                  x-4

Now, x^2 + 9x + 20 factors into   (x+4)(x+5), so what we have now is

       (x+5)(x+4)
------------------------- = 1           This is true for all x, so there are no exclusions.
    (x+4)(x+5)

Tom is the deli manager at a grocery store. He needs to schedule employees to staff the deli department at least 260 person-hour
marissa [1.9K]
If you would like to find the inequality to determine the number of full-time employees Tom must schedule, you can calculate this using the following steps:

n ... the number of full-time employees

260 <= 20 + n * 40
260 - 20 <= n * 40
240 <= n * 40
n >= 240/40
n >= 6 full-time employees

The correct result would be at least 6 full-time employees.

A rectangular deck is 12ft by 14ft. When the length and width are increased by the same amount, the area becomes 288sq. ft. By h
Cerrena [4.2K]

Dimensions of rectangle = 12 + x and 14 + x

(12 + x) (14 + x) = 288

 x^2 + 26x + 168 = 288

 x^2 + 26x - 120 = 0


(x + 30) (x - 4) = 0

x=-30, x =4

 since 4 is positive

 the dimensions increased by 4 feet

check the answer

12+4 = 16

14 +4 = 18

18*16 =288
