Answer:

12/7

Step-by-step explanation:

The value of the expression as a fraction is 12/7.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

6/7 ÷ 1/2

This can be written as,

= (6/7) / (1/2)

= (6 x 2)/7

= 12/7

Thus,

The value is 12/7.

Answer: 4746.09375 dollars (just round down to nine cents)

Step-by-step explanation:

The revenue in the 5th night in two will be $4746.093.

A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.

For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.

Revenue in the first night = $15000

Since revenue of new night is 75% of the previous night

So,

2nd night = 15000 × 75/100 = 11250

3rd night = 8437.5

So the given sequence is ;

15000, 11250, 8437.5 ... it is a GP series.

First term(a) = 15000

Common ratio(r) = 11250/15000 = 0.75

The nth term of a GP is given by ;

[tex]a_{n} = ar^{n-1}[/tex]

So for 5th-night n = 5

So,

a₅ = ar⁵⁻¹

a₅ = 15000(0.75)⁴

a₅ = 4746.093

Hence "The revenue in the 5th night in two will be $4746.093".

Answer:

x < 2

Step-by-step explanation:

Given

5(x - 2) < - 3x + 6 ← distribute parenthesis on left side

5x - 10 < - 3x + 6 ( add 3x to both sides )

8x - 10 < 6 ( add 10 to both sides )

8x < 16 ( divide both sides by 8 )

x < 2

Hey there!☺

[tex]Answer:\boxed{x<2}[/tex]

[tex]Explanation:[/tex]

Let's start by simplifying both sides of the inequality:

[tex]5x-10<-3x+6[/tex]

Now add 3x to both sides:

[tex]5x-10+3x<-3x+6+3x\\8x-10<6[/tex]

In our third step, we will add 10 to both sides:

[tex]8x-10+10<6+10\\8x<16[/tex]

In our last step, we will divide both sides by 8:

[tex]\frac{8x}{8}=\frac{16}{8}[/tex]

Simplify 16/8:

[tex]\frac{16}{8}=2\\ x<2[/tex]

x<2 is your answer.

Answer:

a. S = 1.5C

b. C = $200

Step-by-step explanation:

Firstly, we want to write an equation using retail cost of watch and s for sale price

From the question, we are looking at a markup of 50%

Mathematically therefore;

S = C + (50/100 * c)

S = C + 0.5C

S = 1.5C

Now we want to calculate the cost to the retailer given that the watch was sold as $300 by the retailer

We use the equation:

S = 1.5C

300 = 1.5C

C = 300/1.5

C = $200

Answer:

XM = 1 unit

Step-by-step explanation:

It is given that, M is the midpoint in the segment.

Midpoint bisects the lines such that,

XM = MY

Put XM = x+2 and MY = 2x+3

x+2=2x+3

Taking like terms together,

x-2x=3-2

-x=1

x = -1

Put x = -1 in XM = x+2

(-1) + 2 = 1 = XM

So, the value of XM is 1 unit.

Answer:

The equation of the parabola that models the path of the long jumper through the air is [tex]y = -x^{2}+12\cdot x -27[/tex].

Step-by-step explanation:

Mathematically, we know that parabolas are second-order polynomials and every second-order polynomials, also known as quadratic functions, can be constructed by knowing three different points of the curve. The standard form of the parabola is:

[tex]y = a\cdot x^{2}+b\cdot x + c[/tex]

Where:

[tex]x[/tex] - Horizontal distance from the start line, measured in meters.

[tex]y[/tex] - Height of the long jumper, measured in meters.

[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Polynomial constants, measured in [tex]\frac{1}{m}[/tex], dimensionless and meters, respectively.

If we know that [tex](x_{1},y_{1}) = (3\,m, 0\,m)[/tex], [tex](x_{2},y_{2}) = (8\,m, 0.05\,m)[/tex] and [tex](x_{3}, y_{3}) = (9\,m, 0\,m)[/tex], this system of linear equations is presented below:

[tex]9\cdot a + 3\cdot b + c = 0[/tex] (Eq. 1)

[tex]81\cdot a + 9\cdot b + c = 0[/tex] (Eq. 2)

[tex]64\cdot a + 8\cdot b + c = 0.05[/tex] (Eq. 3)

The coefficients of the polynomial are, respectively:

[tex]a = -\frac{1}{100}[/tex], [tex]b = \frac{3}{25}[/tex], [tex]c = -\frac{27}{100}[/tex]

The equation of the parabola that models the path of the long jumper through the air is [tex]y' = -\frac{1}{100}\cdot x^{2}+\frac{3}{25}\cdot x -\frac{27}{100}[/tex].

But we need [tex]y[/tex] measured in centimeters, then, we use the following conversion:

[tex]y = 100\cdot y'[/tex]

Then, we get that:

[tex]y = -x^{2}+12\cdot x -27[/tex]

Where [tex]x[/tex] and [tex]y[/tex] are measured in meters and centimeters, respectively.

The equation of the parabola that models the path of the long jumper through the air is [tex]y = -x^{2}+12\cdot x -27[/tex].

Answer:

y = -12/(4d - 7d)

Step-by-step explanation:

Step 1: Write equation

4dy + 12 = 7dy

Step 2: Solve for y

Subtract 7dy on both sides: 4dy + 12 - 7dy = 0

Subtract 12 on both sides: 4dy - 7dy = -12

Factor out y: y(4d - 7d) = -12

Divide both sides by 4d - 7d: y = -12/(4d - 7d)

Hello! :)

First thing you do is add -7dy to both sides

4dy + 12 + -7dy = 7dy + -7dy

-3dy + 12 = 0

Next you will have to add -12 to both sides

-3dy + 12 + -12 = 0 + -12

-3dy = -12

Last thing you have to do is divide both sides by -3d

-3dy/-3d = -12/-3d
