Answer:

  $74.67

Step-by-step explanation:

Let p represent the original price. Then the relation is ...

  $56 = p - 0.25×p

  $56 = 0.75p

  $56/0.75 = p ≈ $74.67

The original price was $74.67.

Answer:

180°

Step-by-step explanation:

The measure of an inscribed angle (inscribed inside a circle) is half the measure of its inscribed arc.

m∡H = (1/2)(m arc GJI)

m∡J = (1/2)(m arc GHI)

m∡H + m∡J = (1/2)(m arc GJI + m arc GHI)

But those two arcs added together on the right side are the whole circle, so they add to 360°.

m∡H + m∡J = (1/2)360°

m∡H + m∡J = 180°

Answer: D , p = n (800 - 450) - 3000

Step-by-step explanation: Firstly, you have to account for how much money Rafael is making off of each computer (800 - 450). That factor is then multiplied by the variable "n" which represents the amount of computers sold. Lastly, since this is an equation to calculate his monthly profits, you have to subtract the rent that he is paying ($3000) from the total profit that he made off of selling the computers. Therefore, giving you the equation

P (profit) = n (amount of computers sold) (800-450) - 3000 (rent).

The equation that represents Rafael's monthly profit selling 'n' numbers of computers is D. P = n(800 - 450) - 3000.

An equation represents equality for the terms that are on the both side of the equal sign.

Given Rafael buys computers for 450 dollars and sells them for 800 dollars each.

He also had to pay 3000 dollars for rent and utilities for the store and the number of computers sold in each month is given by 'n'.

∴ The equation that represents his profit(P) in a month is,

P = n(800 - 450) - 3000.

Answer:

60

Step-by-step explanation:

A percentage is divided by 100 to get it's decimal form. So 400/100 = 4.0

Now you take the value given and multiply it by the percentage in decimal form.

So in this case.

15*4 = 60

D. Hyperbola

Step-by-step explanation:

I put B but it was wrong

D is the right answer

The given equation is represent a ''Hyperbola''.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The equation is,

⇒ 9x² - 5x - 3y² - 2y + 4 = 0

Now, We know that;

The standard form of the equation is,

⇒ ax² + by² + 2gx + 2fy + 2hxy + c = 0

For Hyperbola, The condition is,

⇒ h² > ab

For Ellipse ,  The condition is,

⇒ h² < ab

Here, We have;

⇒ h = 0

⇒ a = 9

⇒ b = - 3

⇒ ab = 9 x - 3 = - 27

⇒ h = 0

Hence, We get;

⇒ 0 > - 27

⇒ h² > ab

Thus, This equation is represent a ''Hyperbola''.

To solve this polynomial equation, we first factor the left side.

To factor x² + 8x + 12 = 0, look for factors of 12 that add to 8.

These factors are 6 and 2 so we have (x + 6)(x + 2) = 0.

So either x + 6 = 0 or x + 2 = 0 and solving for

x in each equation, our answer is {-6, -2}.

Answer:

$16.20

Step-by-step explanation:

Bill: $54.00

Tip: 20%

People: 4

To figure out 10% of the bill, you need to move the decimal point over to the left one place: $5.40

10%: $5.40

5.40 times 2 = $10.80

54.00 + 10.80 = 64.80

Grand Total= $64.80

Since there are 4 people, we need to divide by 4:

64.80 divided by 4 = $16.20
