Answer:

1,300 computers

Step-by-step explanation:

As, they are saying they sold 30% of the computers last month

And that 30% was 390

So, x = the total number of computers

30% of x = 390

30% = 30/100 and "of" represents multiplication

So 30/100 X x = 390

We will transpose everything

30x = 39000

x = 39000 ÷ 30 = 1,300

So 1,300 computers were sold

Answer:

44%

Step-by-step explanation:

Given that,

Initial price = $329,550.

Final price = $184,548

We need to find by what percent the value of the condo go down. The percent decrease or increase is givnen by the formula as follows :

[tex]\%=\dfrac{\text{change in value}}{\text{initial value}}\times 100\\\\=\dfrac{329,550-184,548}{329,550}\times 100\\\\=44\%[/tex]

So, the value go down by 44%.

Answer:

4x + 7y = 3365

x + y = 578

x = matinees

y = regular

Step-by-step explanation:

Given

$4 = matinees

$7 = regular

Total tickets = 578

Money collected = $3365

If one calls the amount of matinees that when "x" and the amount of regulars that went "y", then one can form the system;

4x + 7y = 3365

x + y = 578

Solving the system;

Multiply the second equation by (-4)

4x + 7y = 3365

-4x - 4y = -2312

Add the equations

4x + 7y = 3365

-4x -4y = -2312

3y = 1053

Inverse operations

3y = 1053

/3        /3

y = 351

x = 227

Answer:

The correct option is:  A line traveling to the right with an open dot on p = -3.

Option D is correct option.

Step-by-step explanation:

Choose the description that matches the inequality [tex]p > -3[/tex].

The inequality states that, the value of p is greater than -3

For drawing the number line for the inequality, we know that if p > -3, there will be open circle on -3 because -3 is not included and the greater values are on the right side of number line, so line will be travelling to right side.

The number line is attached in figure.

So, The correct option is:  A line traveling to the right with an open dot on p = -3.

Option D is correct option.

Answer:

True, these measures do form a right triangle.

Step-by-step explanation:

Pythagorean Theorem: a^2 + b^2 = c^2

(6)^2 + (8)^2 = (10)^2

Answer:

6.4%

Step-by-step explanation:

We solve this question in using the population growth rate formula

P(t) = Po(1 + r)^t

P(t) = Population after t years = 28 ft

Po = Initial Population = 20 1/2 feet or 20.5 feet

r = Growth rate = ?

t = Time in years = 5

Hence:

28 = 20.5 (1 + r)⁵

Divide both side by 20.5

28/20.5 = 20.5 (1 + r)⁵/20.5

1.3658536585 = (1 + r)⁵

5th root both sides.

5√(1.3658536585) = 5√(1 + r)⁵

1.0643411027 = 1 + r

r = 1.0643411027 - 1

r = 0.0643411027

Converting to percentage

r = 0.0643411027 × 100

r = 6.43411027%

Approximately = 6.4%

The yearly growth rate of the apple tree = 6.4%

Answer:

17.5

105 divided by 6 equals 17.5

18 cars are needed to get all 105 people to the movie.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, 105 people are going to a movie 6 people can ride in each car.

Let the number of cars required be x.

Now, x= Total number of people/Number of people in each car

= 105/6

= 17.5

≈ 18

Therefore, 18 cars are needed to get all 105 people to the movie.

Answer:

y = 2x + 3

Step-by-step explanation:

A line parallel to y = 2x has exactly the same slope but a different y-intercept, b.

Start with y = mx + b, and replace m with 2, y with -1 and x with -2:

-1 = 2(-2) + b, or

-1 = -4 + b.

Then b = 3, and the desired equation is y = 2x + 3

Answer:

60 minutes is 20% of 300 minutes

Step-by-step explanation:

let x be the number of total minutes

60 = 20% of x

20% = 1/5

60 = 1/5x

multiply both sides by 5

300 = x

x = 300 minutes

Answer:

The values of x and y that make the quadrilateral is a parallelogram are x = 12 and y = 21

Step-by-step explanation:

In the given figure

If DEFG is a parallelogram, then DE = GF and DG = EF

∵ DE = GF

∵ DE = 6x - 12 and GF = 2x + 36

→ Equate them

∴ 6x - 12 = 2x + 36

→ Subtract 2x from both sides

∵ 6x - 2x - 12 = 2x - 2x + 36

∴ 4x - 12 = 36

→ Add 12 to both sides

∵ 4x - 12 + 12 = 36 + 12

∴ 4x = 48

→ Divide both sides by 4

∴ x = 12

∵ DG = EF

∵ DG = 6y - 42 and EF = 4y

→ Equate them

∴ 6y - 42 = 4y

→ Add 42 to both sides

∵ 6y - 42 + 42 = 4y + 42

∴ 6y = 4y + 42

→ Subtract 4y from both sides

∵ 6y - 4y = 4y - 4y + 42

∴ 2y = 42

→ Divide both sides by 2

∴ y = 21

∴ The values of x and y that make the quadrilateral is a parallelogram are

   x = 12 and y = 21
