Answer: 2 hours=6 degrees C

              5 hours=-31 degrees C

               Half an hour=9.5 degrees C

I hope this helps. Sorry if I made a mistake. Good luck!

Step-by-step explanation:

9 x 2 hours = 18 C        14-8= 6 degrees C

9 x 5 hours = 45 C       14-45= -31 degrees C

9 x 0.5 = 4.5 C              14-4.5= 9.5 degrees C

The required area of the frame shown is 5x + 3. Option C is correct.

The surface area of any shape is the area of the shape that is faced or the surface area is the amount of area covering the exterior of a 3D shape.

Here,
The area of the picture is given as,
= 2x × x
= 2x²

The area of the whole painting with frame.

= (x + 1)(2x+ 3)
= 2x² + 5x + 3

The area of the frame is given as,
= area of picture with frame - an area of the picture,
= 2x² + 5x + 3 - 2x²
= 5x + 3

Thus, the required area of the frame shown is 5x + 3. Option C is correct.

Answer:

The answer is 70,000 sales.

Bob gets paid an annual salary of $30,000, which means that monthly he gets:

$30,000 : 12 months = $2,500 per month

x - number of sales

Bob earns 5% commission on all sales he makes: x * 5% = x * 0.05 = 0.05x

The function is:

f(x) = 2,500 + 0.05x

Bob wants to make $6,000 this month: f(x) = 6,000

2500 + 0.05x = 6000

0.05x = 6000 - 2500

0.05x = 3500

x = 3500 : 0.05

x = 70000 sales

Step-by-step explanation:

Sales for the month should amount to $70,000

Annual salary = $30,000

Commission on sales = 5%

To make 6000 in a month :

Monthly salary = $30000 / 12 = $2500

Month earning = $2500 + 5% × (monthly sales)

Month earning = $6000

Let month sales = m

6000 = 2500 + 0.05m

6000 - 2500 = 0.05m

3500 = 0.05m

m = 3500 / 0.05

m = 70,000

Sales for the month should be 70,000

Answer:

m=x+6

Step-by-step explanation:

Let's solve for m.

24 pack of mountain dew=9.99

1 pack of mountain dew=9.99/24=0.41625

Answer:

2n + 20

Step-by-step explanation:

Answer:

1) [tex]sin \left(\dfrac{- \pi}{12} \right) = \dfrac{(\sqrt{2} - \sqrt{6} }{4}[/tex]

2) [tex]tan\left(\dfrac{ \pi}{12} \right) = 2 - \sqrt{3}[/tex]

3) [tex]tan\left(\dfrac{ 5\cdot \pi}{12} \right) = 2 + \sqrt{3}[/tex]

Step-by-step explanation:

1) [tex]sin \left(\dfrac{- \pi}{12} \right) = sin(-15^{\circ})[/tex]

sin(-15°)  = sin(30° + (- 45°)) = sin(30°)cos(-45°) + cos(30°)sin(-45°)

sin(30°)cos(-45°) + cos(30°)sin(-45°) = 1/2 × (√2)/2 + (√3)/2 × (-√2)/2

1/2 × √2/2 + √3/2 × -√2/2 = (√2)/4 - (√6)/4 = ((√2) - (√6))/4

sin(-15°)  = ((√2) - (√6))/4

[tex]sin \left(\dfrac{- \pi}{12} \right) = sin(-15^{\circ}) = \dfrac{(\sqrt{2} - \sqrt{6} }{4}[/tex]

2) [tex]tan\left(\dfrac{ \pi}{12} \right) = tan(15^{\circ})[/tex]

tan(15°)  = tan(45° + (-30°)) = (tan(-30°) + tan(45°))/(1 - tan(-30°)×tan(45°))

(tan(-30°) + tan(45°))/(1 - tan(-30°)×tan(45°)) = ((-1/√3) + 1)/(1 - (-1/√3))

((-1/√3) + 1)/(1 - (-1/√3)) = (3 - √3)/(3 + √3) = (3 - √3)·(3 -√3)/((3 - √3)·(3 + √3))

(3 - √3)·(3 -√3/((3 - √3)·(3 + √3)) = (9 - 6·√3 + 3)/(9 - 3) = (12 - 6·√3)/6

(2 - √3)

[tex]tan\left(\dfrac{ \pi}{12} \right) = tan(15^{\circ}) = 2 - \sqrt{3}[/tex]

3) [tex]tan\left(\dfrac{ 5\cdot \pi}{12} \right) = tan(75^{\circ})[/tex]

tan(75°)  = tan(30° + 45°) = (tan(30°) + tan(45°))/(1 - tan(30°)×tan(45°))

(tan(30°) + tan(45°))/(1 - tan(30°)×tan(45°)) = ((1/√3) + 1)/(1 - 1/√3)

((1/√3) + 1)/(1 - 1/√3) = (3 + √3)/(3 - √3) = (3 + √3)·(3 +√3/((3 - √3)·(3 + √3))

(3 + √3)·(3 +√3/((3 - √3)·(3 + √3)) = (9 + 6·√3 + 3)/(9 - 3) = (12 + 6·√3)/6

(12 + 6·√3)/6 = 2 + √3

[tex]tan\left(\dfrac{ 5\cdot \pi}{12} \right) = tan(75^{\circ}) = 2 + \sqrt{3}[/tex]

Adjacent angles: Two angles with a common arm and vertex are called adjacent angles.

They share  a common arm and common vertex.

Adjacent angles are not always equal in measure

Vertical angles: When two lines intersect each other, then the pair of opposite angles formed at the vertex are called vertical angles.

They share a common vertex, but no common arm.

Vertically opposite angles are equal in measure.

#SPJ2

Answer:

line b and c are perpendicular because the product of their slope is -1

Step-by-step explanation:

For two lines to be parallel they must have the same slope

For two line to be perpendicular, the product of their slope must be -1

Line a: 2x-7y=14      

Rewrite in the form y = mx+c

-7y = -2x + 14

y = -2/-7 x + 14/-2

y = 2/7x  - 7

The slope of line a is 2/7

Line b: y=7/2x-8

This is already in standard format

mx = 7/2 x

m = 7/2

The slope of line b is 7/2

Line c: 2x+7y=21

Rewrite in standard form

7y = -2x + 21

y = -2/7 x + 21/7

y = -2/7 x + 3

The slope of line c is -2/7

Take the product of line b and c

mb * mc  = 7/2 * -2/7

mb * mc = -1

Hence line b and c are perpendicular because the product of their slope is -1

Step-by-step explanation:

Answer: 20

Step-by-step explanation:

Step-by-step explanation:

Mary's age = x

Billi's age = x+6

So, Mary age + Billi age = x + (x + 6)

Sum of their ages = 2x + 6

So, 2x + 6= 48

2x = 48 - 6

2x = 42

x = 42/2

Mary age = x = 21

And Billi age = x +6= 21 + 6 = 27

So Mary = 21

And Billi = 27

Lets check!

21 + 27 = 48

So therefore their ages add up to 48

So the answer is correct!

Answer:

[tex]x=-15.8994[/tex]

Step-by-step explanation:

Skills needed: Solving one variable equations, Multiplication

1) We are given: [tex]-11.818=-7+\frac{x}{3.3}[/tex], and we need to solve for "[tex]x[/tex]"

2) In order to do this, you need to isolate the variable. In other words, you need to make sure the term involving  "[tex]x[/tex]" is on one side of the equation, while everything else is on the other side.

3) [tex]-11.818+7 = -7+\frac{x}{3.3} +7[/tex]

[tex]-11.818+7=-4.818[/tex]

-7 and 7 on the right side cancel out.

4) So you are left with: [tex]-4.818=\frac{x}{3.3}[/tex]

5) So then: [tex]-4.818 * 3.3 = x[/tex] (that star sign in between -4.818 and 3.3 is a multiplication sign)

[tex]-4.818*3.3 = -15.8994[/tex], so [tex]x = -15.8994[/tex]

Step-by-step explanation: Khan Academy Explanation

The mean and standard deviation is given by -

μ = 0.35 and σ = 0.09.

Given is that suppose that 35% of students in a school can sing their national anthem correctly. The music teacher takes an SRS of 30 students from the population of 750 students at the school and finds that 40% of students sampled can sing their national anthem correctly. The teacher plans to take more samples like this. Let {p} represent the proportion of a sample of 30 students in the school who can sing their national anthem correctly.

        where -

        {σ} = population standard deviation

        {N} = the size of the population

        x{i} = each value from the population

        {μ} = the population mean

The mean and standard deviation is given by -

μ = 0.35

σ = √(0.35)(0.65)/(30) = 0.48/5.5 = 0.09

σ = 0.09

Therefore, the mean and standard deviation is given by -

μ = 0.35 and σ = 0.09

Answer:

7 or -7

Step-by-step explanation:

the question is asking for x to to the second power which is x squared or x^2

so setting x^2=49

square root both sides of the equation so that x is by itself and the other side is just ±√(49). which ±√49 is just 7 or -7
