Answer:

the original price is $7.89

the price on sale is $6.44

i hope this helps

Step-by-step explanation:

divide $12.88 by 2 to get the price of one of those comic books on sale which gives you $6.44

if you want the original price you just add $1.45 to $6.44 and then thats the price before the sale.

Answer:

$7,562.5

Step-by-step explanation:

Given the function of the profit earned expressed as;

f(p) =-40p^2+1100p

To maximize the profit, df(p)/dp must be sero

df(p)/dp = -80p + 1100 = 0

-80p + 1100 = 0

-80p = - 1100

p = 1100/80

p = 13.75

Substitute p = 13.75 into the function

f(13.75) =-40(13.75)^2+1100(13.75)

f(13.75) = -7,562.5+15,125

f(13.75) = 7,562.5

Hence the symphony should charge $7,562.5 to maximize the profit.

Answer:

a = 49°

Step-by-step explanation:

From the figure attached,

In ΔBOC,

OB = OC = Radii of the circle O

Therefore, m∠OBC = m∠OCB = 41° [Opposite angles of the equal sides of a triangle]

By triangle sum theorem,

m∠OBC + m∠OCB + m∠BOC = 180°

41° + 41° + m∠BOC = 180°

m∠BOC = 180° - 82°

              = 98°

Since, "angle subtended by an arc at the center is twice the angle subtended at the circumference",

m∠BOC = 2(m∠BAC)

98° = 2(a)

a = 49°

Step-by-step explanation:

its C. cause if f -g is equal to positive 4

Option B → (f - g)(x) = [tex]$2x^{3} +5x^{2}[/tex] - 8x - 4  is correct.

We have the following functions -

f(x) = [tex]2x^{3} +5x^{2} -6x-7[/tex]

g(x) = 2x - 3

We have to determine (f - g)(x).

In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.

According to the question, we have -

f(x) = [tex]2x^{3} +5x^{2} -6x-7[/tex]

g(x) = 2x - 3

Now -

(f - g)(x) = {[tex]$2x^{3} +5x^{2} -6x-7[/tex] - (2x - 3)}

(f - g)(x) = {[tex]$2x^{3} +5x^{2}[/tex] - 6x - 7 - 2x + 3}

(f - g)(x) = [tex]$2x^{3} +5x^{2}[/tex] - 8x - 4

Hence, Option B → (f - g)(x) = [tex]$2x^{3} +5x^{2}[/tex] - 8x - 4  is correct.

Answer:

8736

Step-by-step explanation:

The LCM of 156 and 224

First find the highest common factor between the two number

156 = 4 * 39

224 = 4 * 56

Since 4 is the highest common factor between both numbers, the LCM of 156 and 224 will be the product of the highest common factor and the other multiples that are left when the numbers are divided by the highest common factor.

As such, the LCM of 156 and 224

= 4 * 39 * 56

= 8736

Answer:

to get rid of the 3 on the x you have to divide it by 3. whatever you do to one side you have to do to the other side so the answer would be x=8

Step-by-step explanation:

Answer:

x = 8

Step-by-step explanation:

To get the variable alone you would divide both sides by 3. You do this because 3 is a common factor that both 3 and 24 have. Once you divide 3 on each side, you have x = 8 as your final answer.

Answer:

Katrina would need to buy 20 sweatshirts.

Step-by-step explanation:

The number of sweatshirts Katrina would need to order from  each company can be determined by forming the linear equation in two variables.

Given :

Let the number of sweatshirts orders from company MH Designs be 'x' and the number of sweatshirts orders from company Print Rich be 'y'.

So, the cost for ordering the sweatshirt from the company MH Design is:

[tex]21.50x = c[/tex]

Now, the cost for ordering the sweatshirt from the company Print Rich is:

18y + 70 = c'

Given that the number of sweatshirts Katrina would need to order from  each company for the costs to be the same. So :

21.5x = 18y + 70

Now, put the value of x and y so, that in the above equation, both sides become equal.
