At a store, notebooks are on sale for 78% off the regular price. The cost of a notebook is represented by n. Which of the
following expressions does NOT represent the sale price of the notebooks?
O A n +0.22
OB. 0.22n
OC. n - 0.78n
OD. (1 -0.78)

Answer:

The percent error is 83.6.

Answer:

180° - (360/n)°, where n is the number of sides of the polygon.

Step-by-step explanation:

Polygon has n sides.

Divide the polygon radially into n congruent, isosceles triangles.

For each triangle:

 vertex angle = (360/n)°

   sum of base angles = 180° - vertex angle = 180° - (360/n)°

Each interior angle of the n-gon = 180° - (360/n)°

Answer: See explanation

Step-by-step explanation:

Your question isn't complete. First and foremost, to be able to solve this, we need to know the total marks of the examination.

Let's assume that the total marks for the exam is 80. Since Donte scored 55 on his mastery exam, the percent that he score will be:

= 55/80 × 100

= 68.75%

Answer:

the height of the flag = 12cm

Step-by-step explanation:

inclide ladder length = 15m (hypotenuse)

distance between ladder foot and flag foot= 9m (base)

according to Pythagoras theorem,

(h)^2 = (p)^2 + (b)^2

(15)^2 = (p)^2 + (9)^2

(p)^2 = (15)^2 - (9)^2

(p)^2 = 225-81

p = √144

p= 12 cm

Answer:

  x = 12

Step-by-step explanation:

Step(i):-

From graph,

             The angle of the triangle ∝ = 45°

   Given hypotenuse of the triangle

              AC = 12√2  and AB = x

Step(ii):-

we will choose sine function

            [tex]sin\alpha = \frac{opposite side}{hypotenuse}[/tex]

            [tex]sin\alpha = \frac{x}{12\sqrt{2} }[/tex]

 Given that an angle ∝ = 45°

           [tex]sin45 = \frac{x}{12\sqrt{2} }[/tex]

           [tex]\frac{1}{\sqrt{2} } = \frac{x}{12\sqrt{2} }[/tex]

           [tex]\frac{1}{1 } = \frac{x}{12}[/tex]

          x = 12

Final answer:-

x = 12

Answer:

£220 is worth €247

Answer:

$2.40 or $77.55

Step-by-step explanation:

I don't know if you are asking for how much off or what, so I'm doing both

First, we have to find how much we have to take off or what is 30% of 79.95 so our equation is:

79.95 x 0.03 = 2.40

So 30% of 79.95 is $2.40

To find how much our new price sale is, we have to take that $2.40 off so our equation is:

79.95 - 2.4 = 77.55

So our discount price is $77.55

hope this helps:)

Answer:12

Step-by-step explanation:

8500 x 35% = 297.50 in simple interest per year

12000 - 8500 = 3500 in interest earned in total

3500/297.5 = 11.76 number of years to make total interest from amount per year.

If you round up, almost 12 years .

Answer:50

Step-by-step explanation:

15/30= 0.5 which is 1% of the class

Multiply by 100 to get 100% of the class

Answer:

0.008

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Total outcomes:

He will visit 5 different cities. So the total number of ways this can happen is an arrangment of 5 elements, that is:

[tex]T = A_{5} = 5! = 120[/tex]

Desired outcome:

In alphabetical order, so only one possible outcome, which means that [tex]D = 1[/tex]

Probability:

[tex]p = \frac{D}{T} = \frac{1}{120} = 0.008[/tex

Answer:

sorry cnat help ya!

Step-by-step explanation:

Answer:

B = { square numbers less than 30 }.

or

B = {x/x is square of a whole number; [tex]0 \leq x \leq 5[/tex] }

Step-by-step explanation:

Given the set B

B={ 0,1,4,9,16,25}

Let us check the elements in set B.

[tex]x = 0 = 0^{2}[/tex]

[tex]x\:=\:1\:=\:1^2[/tex]

[tex]x\:=\:4\:=\:2^2[/tex]

[tex]x\:=\:9\:=\:3^2[/tex]

[tex]x\:=\:16\:=\:4^2[/tex]

[tex]x\:=\:25\:=\:5^2[/tex]

It is clear that each element in set B is a square of a whole number.

Thus, we can specify set of B by giving a written description of Its element in a variety of ways, such as:

B = { square numbers less than 30 }.

or

B = {x/x is square of a whole number; [tex]0 \leq x \leq 5[/tex] }
