Step-by-step explanation:

a) 1 kilómetro equivale a 1000 metros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

[tex]x = 8000\,m \times \frac{1\,km}{1000\,m}[/tex]

[tex]x = 8\,km[/tex]

b) 1 kilogramo equivale a 1000 gramos, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

[tex]x = 4000\,g \times \frac{1\,kg}{1000\,g}[/tex]

[tex]x = 4\,kg[/tex]

c) 1 kilómetro equivale a 1000 metros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

[tex]x = 3000\,m \times \frac{1\,km}{1000\,m}[/tex]

[tex]x = 3\,km[/tex]

d) 1 metro equivale a 100 centímetros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

[tex]x = 7\,m \times \frac{100\,cm}{1\,m}[/tex]

[tex]x = 700\,cm[/tex]

e) 1 centímetro equivale a 10 milímetros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

[tex]x = 30\,mm \times \frac{1\,cm}{10\,mm}[/tex]

[tex]x = 3\,cm[/tex]

f) 1 centímetro equivale a 10 milímetros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

[tex]x = 10\,cm \times \frac{10\,mm}{1\,cm}[/tex]

[tex]x = 100\,mm[/tex]

g) 1 centímetro equivale a 10 milímetros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

[tex]x = 70\,mm\times \frac{1\,cm}{10\,mm}[/tex]

[tex]x = 7\,mm[/tex]

h) 1 litro equivale a 1000 mililitros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

[tex]x = 10\,L\times \frac{1000\,mL}{1\,L}[/tex]

[tex]x = 10000\,mL[/tex]

i) 1 metro equivale a 100 centímetros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

[tex]x = 800\,cm \times \frac{1\,m}{100\,cm}[/tex]

[tex]x = 8\,m[/tex]

j) 1 kilogramo equivale a 1000 gramos, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

[tex]x = 6\,kg\times \frac{1000\,g}{1\,kg}[/tex]

[tex]x = 6000\,g[/tex]

Answer:

Between - groups variance

Step-by-step explanation:

From the question we see that the college freshmen are assigned to one of the three given groups. This means that they are exposed to different experimental conditions and thus it means that the variation differs as a result of different experimental conditions between the groups.

Thus, these differences reflect between - group variance.

Answer:

Hourly wage at the library = x = $7.5

Hourly wage at the coffee cart = y = $7

Step-by-step explanation:

Let

Hourly wage at the library = x

Hourly wage at the coffee cart = y

On Monday, he works 3 hours at the library and 2 hours at the coffee cart and earns $36.50.

Hence:

3x + 2y = 36.5.... Equation 1

On Tuesday, he works 2 hours at the library and 5 hours at the coffee cart and earns $50.

2x + 5y = 50...... Equation 2

Combining both Equations

3x + 2y = 36.5.... Equation 1

2x + 5y = 50...... Equation 2

We solve using Elimination method, Multiply Equation 1 by 2 and Equation 2 by 3 which are coefficients of x to eliminate x

6x + 4y = 73 .. Equation 3

6x + 15y = 150...... Equation 4

Subtract Equation 3 from Equation 4

11y = 77

y = 77/11

y = 7

Solving for x using Equation 2

2x + 5y = 50...... Equation 2

2x + 5 × 7 = 50

2x + 35 = 50

2x = 50-35

2x = 15

x = 15/2

x = 7.5

Therefore,

Hourly wage at the library = x = $7.5

Hourly wage at the coffee cart = y = $7

Answer:

[tex] {x}^{2} + 11x + 30[/tex]

Step-by-step explanation:

Area is length x width

The length is

[tex](x + 6)[/tex]

The width is

[tex](x + 5)[/tex]

Multiply both using FOIL Method

[tex](x + 6)(x + 5)[/tex]

[tex] {x}^{2} [/tex]

[tex]6 \times x = 6x[/tex]

[tex]5 \times x = 5x[/tex]

[tex]6 \times 5 = 30[/tex]

Write in standform form

[tex] {x}^{2} + 6x + 5x + 30[/tex]

[tex] {x}^{2} + 11x + 30[/tex]

The abbreviation CD stands for "Compact Disc."

A compact disc is a small, portable, round disc that is used for storing and playing back digital audio, video, and other types of data. It was introduced in the early 1980s as a replacement for vinyl records and cassette tapes.

A CD is made up of a polycarbonate plastic layer that is coated with a reflective metal layer and protected by a clear plastic layer. Information is stored on the disc in the form of tiny pits and lands that are read by a laser beam in a CD player or computer CD-ROM drive.

CDs have a storage capacity of up to 700 MB, which allows for around 80 minutes of audio or several hours of compressed video. They are commonly used for storing music albums, software programs, and other types of multimedia content.

In addition to audio CDs, there are also CD-ROMs (read-only memory), CD-Rs (recordable), and CD-RWs (rewritable). CD-ROMs are pre-recorded discs that cannot be modified, while CD-Rs and CD-RWs can be burned or written with data by the user. CD-Rs can only be written once, while CD-RWs can be erased and re-written multiple times.

Overall, the abbreviation CD refers to the Compact Disc, a versatile medium for storing and playing back digital data.

Step-by-step explanation:

distance formula

Answer:

r will be half of your diameter so 11 divided by 2 = 5.5 is your new radius.

To find surface area we use the basic formula:

4πr^2

4 x 3.14 x 30.25(radius squared, 5.5 x 5.5 = 30.25) = 379.94 ft^2 is your surface area

Answer:

Step-by-step explanation:

Answer:

x = 2.5 or 5/2.

Step-by-step explanation:

They're congruent angle, so set them equal to each other

5x + 13 = x + 23

Solve for x:

4x = 10

x = 10/4 = 5/2 = 2.5

D. 5x5x5x5 = 625

Answer:

5⁴ has the greatest value

Step-by-step explanation:

9² = 9 x 9 = 81

2⁵ = 2 x 2 x 2 x 2 x 2 = 32

10² = 10 x 10 = 100

5⁴ = 5 x 5 x 5 x 5 = 624

Therefore, 5⁴ has the greatest value!

x=67º

Step-by-step explanation:

First since the supplementary angle next to 157º is in the triangle, we can find that. 180-157 = 23. Then we can use triangle angle sum theorem to find x. 180-(23+90) = 67º

Answer: #444

Step-by-step explanation:

First find the original selling price of the article.

When sold for #372 the profit was 24%. Assume the original price is x.

372 = x + 24% * x

372 = 1.24x

x = 372 / 1.24

= #300

If he wanted to make a profit of 48% he should have sold for:

= Original price + (original price * 48%)

= 300 + (300 * 48%)

= #444
