Answer:

Ribbon can't be enough

Step-by-step explanation:

Markin is making a flag shaped like a square. Each side measures 13 m. He wants to add ribbon along the edges. He has 48 m of ribbon. Does he have enough ribbon? If it is not enough,how much more ribbon needed?

Given :

Side length of square shaped flag = 13 m

Length of ribbon markin has to add along edges = 48 m

To know if the ribbon will enough ; we obtain the perimeter of the square shaped flag ;

4 * side length

4 * 13 = 52 meters

52 > 48

Since the perimeter is greater than the length of ribbon, then ribbon can't be enough

a piece of luggage sells for $225.00 it is on sale this week for $195.00 what is the percent decrease to the nearest whole perce
viktelen [127]

Answer: 13%

Step-by-step explanation:

Given : A piece of luggage sells for $225.00 it is on sale this week for $195.00 .

Decrease in price = $225.00-$195.00= $30.00

Formula to find the percent decrease :-

\dfrac{\text{Decrease in price}}{\text{Previous price}}\times100\\\\=\dfrac{30}{225}\times100=13.3333333333\approx13\%\ \ [\text{Rounded to the nearest whole percent.}]

Hence, the  percent decrease = 13%

If f(x)=3 x and g(x)= 1/x , what is the domain of (g o f)(x)?
aliya0001 [1]

Answer:

The domain is (-∞ , 0)∪(0 , ∞) OR The domain is {x : x ≠ 0}

Step-by-step explanation:

* Lets revise the composite function

- A composite function is a function that depends on another function.

- A composite function is created when one function is substituted into

 another function.

- Ex: f(g(x)) is the composite function that is formed when g(x) is

 substituted for x in f(x).

- In the composition (f ο g)(x), the domain of f becomes g(x).

* Lets solve the problem

∵ f(x) = 3x and g(x) = 1/x

- In (g o f)(x) we will substitute x in g by f

∴ (g o f)(x) = 1/3x

- The domain of the function is all real values of x which make the

  function defined

- In the rational function r(x) = p(x)/q(x) the domain is all real numbers

 except the values of x which make q(x) =0

∵ (g o f)(x) = 1/3x

∵ 3x = 0 ⇒ divide both side by 3

∴ x = 0

∴ The domain of (g o f)(x) is all real numbers except x = 0

∴ The domain is (-∞ , 0)∪(0 , ∞) OR The domain is {x : x ≠ 0}

The chart shows the population each year for a small town.
Novay_Z [31]

Answer:

69.77 % population increased from year 1 to year 5

Step-by-step explanation:

Population  of year 1 = 2150

Population of year 2 = 3650

increase in population = 3650-2150 = 1500

Percentage increase =   ( increased/intial) x 100

                                    =    (1500/2150) x 100

                                   =  69.77
