Answer:

1.91/9

Step-by-step explanation:

x=0.212121212........                                                         .........1  equation

10x=2.12121212.........                                                       ........2   equation

1 equation - 2 equation

9x=1.91

x=1.91/9

therefore 0.212121.....=1.91/9

Answer:

El tiempo que tardarán Lourdes y Rosabel en hacer el trabajo juntas es de 3,6 horas.

Step-by-step explanation:

Los parámetros dados son;

El tiempo que tarda Lourdes en leer las letras = 6 horas

El tiempo que le toma a Rosabel leer las letras = 9 horas

Sea la cantidad total de trabajo de oficina = X

Deje que el tiempo que ambos tienen que trabajar para hacer el trabajo = t

Por lo tanto;

La tasa de trabajo de Lourdes = X / 6

La tasa de trabajo de Rosabel = X / 9

X / 6 × t + X / 9 × t = X

t × (1/6 + 1/9) = 1

t × 5/18 = 1

t = 18/5 = 3,6 horas

Por lo tanto;

El tiempo que les llevará a Lourdes y Rosabel hacer el trabajo juntas = 3.6 horas.

Answer:

where x is the length of the first place

[tex]x+1x+5x+1=27[/tex]

[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: 5418.54 feet

Step-by-step explanation:

Given: Nadia started at 19.26 feet below sea level.

She climbed a total of 5,437.8 feet up from her initial position.

Since we take negative integers to show depth .

Here,  19.26 feet below sea level. means - 19.26 feet respective to sea level

So her altitude at the end of her climb above sea level = 5437.8-19.26 feet =

= 5418.54 feet

Hence, Nadia's altitude at the end of her climb was 5418.54 feet.

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:

Option 2

Step-by-step explanation:

Let's say that Phalicia opens her savings account one year (12 months) before she goes to college.

With Option 1, she would have saved 300 + 50 * 11 = $850. We do 50 * 11 and not 50 * 12 because she deposits $50 for 11 months, not 12.

With Option 2, she would have saved 5 * 3¹¹ = $885735. Note that we do 3¹¹ and not 3¹² because 5 is being tripled 11 times.

Obviously, she should choose Option 2 because she saves A LOT more money.

Additionally, we can notice that Option 1 is an example of an arithmetic sequence whereas Option 2 is an example of a geometric sequence. Their explicit formulas would be aₙ = 50n + 250 and aₙ = 5 * 3⁽ⁿ⁻¹⁾ respectively.

Answer:

40.135

Step-by-step explanation:

Use a calculator?

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:

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:

[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]

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)

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.
