A chair can be purchased in one of four colors: red, white, green, or blue. The number of chairs purchased in each color is listed below. Red: 150 white: 450 green: 225 blue: 375 Based on the information shown in the list, what is the probability that the next chair purchased will be red?

### Answers

**Answer:**

[tex]P(Red) = 0.125[/tex]

**Step-by-step explanation:**

**Given**

[tex]Red: 150[/tex]

[tex]White: 450[/tex]

[tex]Green: 225[/tex]

[tex]Blue: 375[/tex]

**Required**

Determine the probability of getting a red chair, next.

**First, we nee the total number of chairs**

[tex]Total = 150 + 450 + 225 + 375[/tex]

[tex]Total = 1200[/tex]

**Probability of getting red is then calculated as thus;**

[tex]P(Red) = Red/Total[/tex]

[tex]P(Red) = 150/1200[/tex]

[tex]P(Red) = 0.125[/tex]

O ZORP and ZORN are a linear pair

O ZORP and ZORN are vertical angles

O 80 = 3x +10

O x = 30

### Answers

(a) ∠ORP and ∠ORN are a linear pair .

Let us prove that option a , is the correct option by finding the value of x .

Angle ORP and angle ORN are a linear , which means their sum will be equal to 180° .

So :-

[tex]80 + 3x + 10 = 180[/tex]

[tex]3x + 80 + 10 = 180[/tex]

[tex]3x + 90 = 180[/tex]

[tex]3x = 180 - 90[/tex]

[tex]3x = 90[/tex]

[tex]x = \frac{90}{3} [/tex]

[tex]x = 30°[/tex]

As we were able to find put the value of x only after we cam to know that ∠ORP and ∠ORN are a linear pair , we say that option a is the correct statement .

Therefore , the correct answer is :-

**(a) ∠ORP and ∠ORN are a linear pair .**

The **value **of x is **equal **to 30°. Hence, proved.

What are angles at a point on a straight line?

**Angles **on a straight line relate to the sum of angles that can be arranged together so that they form a** straight line**. Angles on a straight line add to 180°.

Given that, m∠ORP=80° and m∠ORN=(3x+10)°.

Here, m∠ORP+m∠ORN=180° (Angles on straight line adds upto 180°)

80°+(3x+10)°=180°

90°+3x=180°

3x=90°

x=90°/3

x=30°

Hence, proved.

Alex has twice as much money as Jennifer. Jennifer has $6 less than Shannon. Together they have $54. How much money does each have?

### Answers

**Answer:**

**Alex has twice as much money as Jennifer.**

**a = 2j**

**Jennifer has $6 less than Shannon.**

**j = s-6**

**j+6 = s**

**All together the three friends have $54.**

**a + j + s = 54**

**Replace a and s**

**2j + j + (j+6) = 54**

**4j = 54 - 6**

**4j = 48**

**j = 48/4**

**j = 12 **

**Jennifer has $12**

**Alex= 2*12 = $24**

**Shannon = 24+12+s = 54**

**= 36+s = 54**

**s = 18**

**Shannon has $18**

Jamila is walking her small dog for a walk around her neighborhood. They travel 3/5 They travel 3/5of a mile in 40 minutes. Determine the unit rate they walk in minutes per hour.

### Answers

**Answer:**

**unit rate = 0.9 miles per hour **

**Step-by-step explanation:**

Rate per hour of walking is calculate by = distance moved in miles/ time taken in miles

_________________________

given

distance = 3/5 of a mile = 3/5 miles

time = 40 minutes

we have to find time in hours

60 minutes = 1 hour

40 minutes = 1/60 *40 hours = 2/3 hours

thus

unit rate = (3/5 miles)/ (2/3 hours ) = (3*3)miles/(5*2) hour = 9/10 miles per hour

**unit rate = 0.9 miles per hour **

Using the figure below, find the measure of z ( just enter in the number for your answer don’t worry about the degree symbol or saying “ degrees” after the number

### Answers

**Answer:**

z = 29°

**Step-by-step explanation:**

We know that the 3 angles in a triangle always add up to 180°. So for triangle ABC, angle A = 59° (given), and angle B = 43° + 49° = 92° (given).

angle A + angle B + angle C = 180°

59° + 92° + z = 180°

151° + z = 180°

Subtract 151° from both sides of the equation

z = 180° -151°

z = 29°

What are trigonometric equations?

These are the **equation **that contains **trigonometric operators **such as sin, cos.. etc.. In **algebraic operation**.

Diameter = 200

Radius = Diameter/2 = 100

Rotational angle = 60°

Let the height be h
