Step-by-step explanation:

Emma has just started a new sales job. She makes $20 an hour. On top of her hourly wages, she’ll be paid a commission of 15% on all sales she makes. Use this information to answer the following questions.

Part A
Question
Which equation in the form y = mx + cs models Emma’s situation?

y = 20x + 0.15
y = 20x + 15
y = 20x + 0.15s
y = 20x + 15s

Answers

Answer:

y = 20x + 0.15s

Step-by-step explanation:

Shew makes $20 par hour, so for x hours, she makes 20x.

She makes 15% commission on the sales, s. 15% = 0.15,so for the sales, s, she makes 15% * s = 0.15s.

The total she makes is 20x + 0.15s

Answer: y = 20x + 0.15s

The equation in the form y = mx + cs models Emma’s situation is

y = 20x + 0.15s

Shew makes $20 par hour, so for x hours, she makes 20x.

What is the slope-intercept form of the line?

The slope-intercept of the line y= mx+c

Where y co-ordinate

x-  x co-ordinate

m=slope of the given line

C-y intercept.

She makes 15% commission on the sales, s. 15% = 0.15,

So for the sales, she makes

15% * s = 0.15s.

The total she makes is 20x + 0.15s

y = 20x + 0.15s

A skyscraper is a rectangular prism with a height of 398 meters. The bases are squares with sides that are 62 meters. What is the surface area of the skyscraper?

Answers

Answer:

106,392 meters squared.

Step-by-step explanation:

Surface area of a rectangular prism or cuboid is given by:

SA = 2 (lw + wh + lh)

where:

· l is the length of the cuboid.

· w is the width of the cuboid.

· h is the length of the cuboid.

Here we have h = 398 m, l = w = 62 m because this is a square base.

So we get:

SA = 2 ( 398 · 62 + 62² + 398 · 62)

= 2 (24676 + 3844 + 24676)

= 2 · 53196

= 106392 m²

I'm so confused, and i need to solve for h.

Answers

Answer:

Step-by-step explanation:

Begin by multiplying both sides by 2

2*A  =  2*(b1 + b2) * h/2                        Cancel the 2s

2A = (b1 + b2 ) * h                                 Divide both sides by (b1 + b2)

2A/(b1 + b2) = (b1 + b2)*h / (b1+b2)     Cancel B1 + b2

2A/(b1 + b2) = h

Part B: Is the point (8, 10) included in the solution area for the system? Justify your answer mathematically. (4 points)
(10 points)

Answers

Answer:

Step-by-step explanation:

y > 3x + 10

y < -3x - 1

Part A:

You'd graph the given systems of linear inequalities the same way as you graph the linear equations.  

To graph y > 3x + 10, plot the y-intercept, (0, 10), then use the slope, m = 3 (rise 3, run 1), to plot other points on the graph.  Use a dashed line (because of the ">" symbol).  

Follow the same steps for the other linear inequality. Plot the y-intercept, (0, -1), then use the slope, m = -3 (down 3, run 1) to plot other points. Use a dashed line (because of the "<" symbol).  

Pick a test point on either side of the boundary line and plug it into the original problem.  This will help determine which side of the boundary line is the solution.  Plug in a test point that is not on the boundary line.

Use the point of origin, (0, 0) as the test point. Plug in these values into the given systems of linear inequalities to see whether it will provide a true statement.  

y > 3x + 10

0 > 3(0) + 10

0 > 0 + 10

0 > 10 (False statement).  

y < -3x - 1

0 < -3(0) - 1

0 < 0 - 1

0 < -1 (false statement).  

Since the point of origin provided a false statement to the given systems of linear inequalities, you must shade the half-plane region where it doesn't contain the test point.  

Part B:

You'll do the same process as what I've done for the test point. Plug in the values of (8, 10) into the given systems of linear inequalities. If it provides a false statement, then it means that it is not a solution to the system.  

y > 3x + 10

10 > 3(8) + 10

10 > 24 + 10

10 > 34 (False statement).  

y < -3x - 1  

10 < -3(8) - 1

10 < -24 - 1

10 < -25 (false statement).  

Therefore, (8, 10) is not a solution to the system.

Answers

The quadrilaterals are similar and are related by a scale factor, taken from

a specific location, that maps the points on one figure to the other.

a. The scale factor that takes Figure 1 to Figure 2, is 3

b. The scale factor that takes Figure 2 to Figure 1 is [tex]\dfrac{1}{3}[/tex]

Reasons:

From the question, we have that Figure 1 is a scaled copy of Figure 2, therefore;

Let ABCD represent Figure 1, we have;

ABCD ~ PQRS

Length of [tex]\overline{AD}[/tex] = √(2² + 3²) = √(13)

Length of [tex]\overline{PS}[/tex] = √(6² + 9²) = √(117) = √(9 × 13) = 3·√(13)

Therefore;

a. The scale factor that takes Figure 1 to Figure 2, SF₁₂, is therefore;

[tex]SF_{12} = \mathbf{\dfrac{\overline{PS}}{\overline{AD}}}[/tex]

Which gives;

[tex]SF_{12} = \dfrac{3 \cdot \sqrt{13} }{\sqrt{13} } = 3[/tex]

The scale factor that takes Figure 1 to Figure 2, SF₁₂ = 3

(3 times the lengths of Figure 1 gives the lengths on Figure 2)

b. The scale factor that takes Figure 2 to Figure 1, SF₂₁, is given as follows;

[tex]SF_{21} = \mathbf{\dfrac{\overline{AD}}{\overline{PS}}}[/tex]

Which give;

[tex]SF_{21} = \dfrac{\sqrt{13} }{3 \cdot \sqrt{13} } = \mathbf{\dfrac{1}{3}}[/tex]

The scale factor that takes Figure 2 to Figure 1, SF₂₁ is [tex]\underline{\dfrac{1}{3}}[/tex]

Solve 4(x−5)=6x. You must SHOW EACH STEP for full credit.

Answers

Answer:

x = − 10

Step-by-step explanation:

Let's solve your equation step-by-step.

4 ( x − 5 ) = 6x

Step 1: Simplify both sides of the equation.

4 ( x − 5 ) = 6x

( 4 ) ( x ) + ( 4 ) ( − 5 ) = 6x ( Distribute )

4x + − 20 = 6x

4x − 20 = 6x

Step 2: Subtract 6x from both sides.

4x − 20 − 6x = 6x − 6x

− 2x − 20 = 0

Step 3: Add 20 to both sides.

− 2x − 20 + 20 = 0 + 20 − 2x = 20

Step 4: Divide both sides by -2.

− 2x / − 2 = 20 / − 2

x = − 10
