Linear, [tex]\frac{4}{-3}[/tex] is the slope

Step-by-step explanation:

Its linear because the rate of change doesn't change throughout our points.

Lets use our coordinate points for the bottom and middle one, making 1 our rate of our graph.

The bottom one that's closest to the x-axis would be (8,2). Move 8, the x, to the right, and up 2, the y The middle one of the points would be (5,6). Move 5, the x, to the right, and up 6, the y.

We have our points, now we find the rate of change, also known as slope.

So the equation for slope is m = [tex]\frac{db}{ca}[/tex] and our points together is (8,2)(5,6). Line up the variables with our points. So for example, 8 would be A, 2 would be B, 5 would be C and so on.

Then we have [tex]\frac{6-2}{5-8}[/tex]. Solve it, and we get [tex]\frac{4}{-3}[/tex].

Total commission= $10,237.5

Step-by-step explanation:

Giving the following information:

A real estate agent sold a house for $315,000 last week.

Commission= 3.25%

To calculate the value of the commission, we need to use the following formula:

Total commission= house value*commission percentage

Total commission= 315,000*0.0325

Total commission= $10,237.5

Answer:

4 people will receive both a t-shirt and a keychain.  

Step-by-step explanation:

To determine how many people will receive both a t-shirt and a keychain,

First we will determine those that will receive a t-shirt and as well determine those that will receive a keychain.

For those that will a receive a t-shirt

Since every 8th person receives a t-shirt, then

The 8th, 16th, 24th, 32nd, 40th, 48th, 56th, 64th, 72nd, 80th, 88th, 96th, 104th, 112th. 120th, 128th, 136th, 144th, 152nd, and 160th persons will receive a t-shirt.

For those that will receive a keychain

Since every 10th person receives a keychain, then

The 10th, 20th, 30th, 40th, 50th, 60th, 70th, 80th, 90th, 100th, 110th, 120th, 130th, 140th, 150th, and 160th persons will receive a keychain.

From above, those that will receive both a t-shirt and a keychain are the 40th, 80th, 120th, and 160th persons.

Hence, 4 people will receive both a t-shirt and a keychain.

Answer:

28°

Step-by-step explanation:

Complementary angles sum to 90° , thus

∠ DEF + ∠ LMN = 90°, that is

62° + ∠ LMN = 90° ( subtract 62° from both sides )

∠ LMN = 28°

Answer:

The integer that represent the total change in time when 5 clues are used is 10

Step-by-step explanation:

The given parameters are;

The number of free clues available = 3

The number of minutes removed for an additional clue = 5 minutes

Therefore, the total change in time when 5 clues are used is given as follows;

The number of free clues available 3

The number of clues for which 5 minutes is removed from the remaining time when 5 clues are selected = 5 - 3 = 2 clues

Therefore, the total change in time = The number additional clues × 5 minutes/clue

The total change in time = 2 clues × 5 minutes/clue = 10 minutes

The total change in time = 10 minutes

Therefore, the integer that represent the total change in time (in minutes) when 5 clues are used = 10.

Step-by-step explanation:

Answer:

Its true

Step-by-step explanation:

Answer:

The answer is below

Step-by-step explanation:

The road increases by a height of 1 m for every 15 m distance. The slope of a line is the ratio of its rise to run. The slope (m) is the tangent of the inclination. Hence:

Slope = rise / run = tanθ

Where θ is the angle of inclination.

a) Given rise = 1 m, run = 15 m

Slope of road (m) = rise / run

m = 1 m/ 15 m

m = 0.0667

slope = tanθ

tanθ = 0.0667

θ = tan⁻¹(0.0667)

θ = 3.81

θ ≈ 4°

b) cosθ = horizontal distance / 15 m

horizontal distance = 15 m × cos 4

Horizontal distance = 14.96

Horizontal distance = 15 m to nearest tenth

Answer: {-1, 0}

Explanation: Since y = -7x - 7, we can replace the y in our first equation with

a -7x - 7 and our first equation now reads 4x + 4(-7x - 7) = -4.

To solve this equation, first distribute the 4 through the parenthses.

So we have 4x - 28x - 28 = -4.

Now simplify the left side to get -24x - 28 = -4.

Adding 28 to both sides, we have -24x = 24.

Dividing both sides by -24, we find that x = -1.

To find y, plug a -1 back into either equation.

So we have y = -7(-1) - 7 or y = 0.

Our final answer is {-1, 0}.

Answer:

x= -1,

y=0

Answer:

Step-by-step explanation:

Henry and Irene working together can wash all the windows of their house in 1 h 40 min. Working alone, it takes Henry 2 1 /2 h more than Irene to do the job. How long does it take each person working alone to wash all the windows?

Let us represent

The number of hours Irene takes to do the job alone =x

1/x=Irene's work rate

The number of hours Henry takes to do the job alone = x + 2.5

1/(x+2.5)=Henry's work rate

1 hr and 40 min

Converting the 40 minutes to hour

60 mins = 1 hour

40 mins = x

x = 40/60

x = 0.6666666667 hour

1 hour 40 minutes = 1.67hours

Irene and Henry working together to do the job

Their work rate working together

sum of individual work rates=work rate when working together

1/x+1/(x+2.5)=1/1.67

LCD:(x)(x+2.5)(1.67)

(x+2.5)(1.67)+(1.67)(x)=(x)(x+2.5)

1.67x+ 4.175 +1.67x=x^2+2.5x

x^2+ 2.5x - 3.38x - 4.175

x^2- 0.84x - 4.175

Using Almighty formula

x = 42 minutes

x + 2.5 +

0.42 + 2.5 = 2.92 hours

The diameter of the larger circle is 22.50 mm

Step-by-step explanation:

Given;

ratio of radii of two circles = 2:3

diameter of the smaller circle, d = 15 mm

let the diameter of the larger circle = D

The ratio of the radii of the two circles is given by;

[tex]\frac{2r}{2R}= \frac{d}{D}= \frac{2}{3}\\\\ D= \frac{3d}{2}\\\\ D = \frac{3*15}{2} \\\\D = 22.50 \ mm[/tex]

Therefore, the diameter of the larger circle is 22.50 mm

Answer:

B) 9

Step-by-step explanation:

According to the statement, we have the following relationship:

[tex]y \propto x[/tex]

[tex]y = k\cdot x[/tex] (Eq. 1)

Where:

[tex]k[/tex] - Proportionality constant, dimensionless.

[tex]x[/tex] - Independent variable, dimensionless.

[tex]y[/tex] - Dependent variable, dimensionless.

Such constant is eliminated by constructing this relationship:

[tex]\frac{y_{2}}{y_{1}} = \frac{x_{2}}{x_{1}}[/tex]

[tex]x_{2} = \left(\frac{y_{2}}{y_{1}} \right)\cdot x_{1}[/tex] (Eq. 2)

If we know that [tex]y_{1} = 56[/tex], [tex]x_{1} = 6[/tex] and [tex]y_{2} = 84[/tex], then the value of [tex]x_{2}[/tex] is:

[tex]x_{2} = \left(\frac{84}{56} \right)\cdot (6)[/tex]

[tex]x_{2} = 9[/tex]

Hence, the correct answer is B.
