Proportional relationships are written in the form y = kx where k is the constant of proportionality. In this case, k = 10 so the answer is 10.

Answer:

[tex]\$10x + \$94\geq\ \$194[/tex]

Step-by-step explanation:

Given

Wage = $10 per hour

Savings = $94

Stereo = $194

Required

Represent the scenario using an inequality

From the question, x represents the number of hours.

If his wage is $10 per hour then, his wage is $10x in x hours

Solving further;

For George to afford the stereo, the sum of his wages and savings must be greater than or equal to the cost of the stereo

Mathematically, this is:

[tex]Wages + Savings \geq\ Stereo[/tex]

Substitute right values for the above expression

[tex]\$10x + \$94\geq\ \$194[/tex]

The options are not well presented, hwever the solution is [tex]\$10x + \$94\geq\ \$194[/tex]

  6x3 - 9x  =   3x • (2x2 - 3)  

Trying to factor as a Difference of Squares:

6.2      Factoring:  2x2 - 3  

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check :  2  is not a square !!

Ruling : Binomial can not be factored as the

difference of two perfect squares

Final result :

 3x • (2x2 - 3)

[tex]x=\frac{26}{7}[/tex]

Answer:

first piece: 3.25 inches

second piece: 6.5 inches

third piece: 17.25 inches

Step-by-step explanation:

a + b + c = 27

b = 2a

c = 5a + 1

a = first piece length

b = second piece length

c = third piece length

then:

a + 2a + (5a+1) = 27

8a + 1 = 27

8a = 27-1

8a = 26

a = 26/8

a = 3.25 in

b = 2a

b = 2*3.25

b = 6.5 in

c = 5a+1

c = 5*3.25  +  1

c = 16.25 + 1

c = 17.25 in

Check:

3.25 + 6.5 + 17.25 = 27

Answer:

[tex]x = \frac{c-b}{a}[/tex]

Step-by-step explanation:

To solve for x, x needs to be on one side while all the other variables are on the other

To do this first subtract b from each side making the equation,

ax = c - b

Now divide by a on both sides. This means that to solve for x the equation must be ...

[tex]x = \frac{c-b}{a}[/tex]

Answer:

Step-by-step explanation:

Since ∆LMM is a triangle all it's interior angles sum up to 180°

To find M add up all the angles and N and equate it to 180° to find N

That's

L + M + N = 180

33 + N + 79 = 180

N + 112 = 180

N = 180 - 112

Answer:

[tex]x=\frac{-10-z}{y}[/tex]

Step-by-step explanation:

1 Subtract z from both sides.

[tex]-10-z=xy[/tex]

2 Divide both sides by y

2 Multiply both sides by j.

[tex]-4=(k-h)j[/tex]

3 Divide both sides by k−h.

[tex]-\frac{4}{k-h}=j[/tex]

4 Switch sides.

[tex]j=-\frac{4}{k-h}[/tex]

[tex]\rule[225]{225}{2}[/tex]

Step-by-step explanation:

Solving for x:

[tex]-10=xy+z[/tex]

Subtracting z from both sides:

[tex]-10-z=xy[/tex]

Divding both sides by y:

[tex]\displaystyle \frac{-10-z}{y} =x[/tex]

Solving for j:

[tex]\displaystyle h-\frac{4}{j} =k[/tex]

Subtracting h from both sides:

[tex]\displaystyle - \frac{4}{j} =-h+k[/tex]

Multiplying both sides by j,

then dividing both sides by (-h + k):

[tex]\displaystyle - \frac{4}{-h+k} =j[/tex]

Simplifying the equation:

[tex]\displaystyle \frac{4}{-(-h+k)} =j[/tex]

[tex]\displaystyle \frac{4}{h-k} =j[/tex]

Thanks to the people who commented the correct answer on the wrong answer!

Ben's average speed will be equal to 70.5 meters per minute.

Calculating average speed involves dividing the whole distance travelled by the total time it took to cover that distance. Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance.

It is given that Ben walks 500 meters from his house to the corner store. He then walks back toward his house but continues 200 meters past his house to talk to a neighbour. It takes Ben 17 minutes from the time he leaves his house until he stops to talk to his neighbour.

The average speed is calculated as below:-

Average speed = Total distance / Total time

Average speed = ( 500 + 500 + 200 ) / 17

Average speed = ( 1200 ) / 17

Average speed = 70.5 meters per minute.

Therefore, Ben's average speed will be equal to 70.5 meters per minute.

Answer: 2/23

Step-by-step explanation: Absolute value is a term which is used to indicate the distance of a point or number from the origin of a number line or coordinate system.

Suppose x is a real number. Then the absolute value of x is defined as follows:

For x = 0 or x > 0, | x | = x

For x < 0, | x | = - x

Now, we have to find the absolute value of the given number  that means we have to find the distance of   from the origin of a number line.

Distance of  from the origin is  . As distance can never be negative.

Therefore, the absolute value of  is 2/23 .

Its already a decimal because its no longer a fraction.

Step-by-step explanation:

35000/1 = 35000 or 35000.0

Unless you have:

Answer:

About 66 tubes

Step-by-step explanation:

Cylinder surface area formula: 2πr(h + r) where h = height and r = radius

In this case, h = 14, π = 3.14 and r = 4.5 so the surface area of one pottery is:

2 * π * 4.5 * (14 + 4.5) = 166.5π ≈ 523.08

The surface area of 15 potteries would be 523.08 * 15 = 7846.2 so it would take 7846.2 / 120 = 65.385 ≈ 66 tubes. We round to the nearest integer because in this context, you can only have integer values of tubes, you can't have, say, 0.5 tubes.

Answer:

40

Step-by-step explanation:

Variability is a measures of the interquartile range of a given set of data. The greater the interquartile range, the more the variability.

The interquartile range (IQR) = Third quartile (Q3) - First Quartile (Q1)

IQR for City A = 70 - 40 = 30

IQR for City B = 80 - 40 = 40.

City B has a greater IQR value, therefore, it has the greater variability in temperature.

The interquartile range for the city with greater variability is 40.

Answer:

d = 13  (distance between two points)

Step-by-step explanation:

(4, -2) and (-1, 10)

(X1, Y1)  and (X2, y2)

distance between two points = d = sqrt (X2 - X1)² + (Y2 - Y1)²

d = √ (-1 - 4)² + (10 - (-2))²

d = √25 + 144

d = √169

d = 13  (distance between two points)
