Answer:

3,9,and 36

Step-by-step explanation:

small=x

median=3x

big=12x

x+3x+12x=48

16x=48

x=3

3=small

3*3=9  (median)

9*4=36(big)

3+9+36 = 48

The problem is solved by setting up and solving an equation where 'x' represents the length of the first piece. The three pieces of the wire measure 3ft, 9ft, and 36ft respectively.

The question is about finding the length of each piece of a 48ft wire when it's divided into 3 pieces, with each piece having a specific relative length. Let's denote the length of the first piece as 'x'. According to the problem, the second piece is three times as long as the first one, so it's '3x', and the third is four times as long as the second, so it's '4*3x', which simplifies to '12x'.

Combining all these pieces, we get the total length of the wire: x + 3x + 12x = 48ft. This simplifies to 16x = 48ft. Finally, solving for 'x', we find that x = 48ft / 16 = 3ft. Therefore, the three pieces of the wire measure 3ft, 9ft, and 36ft respectively.

Answer:

$4,290.69

------------------------------------------------------------------------------------------------------

- To find the commission, just convert the percentage into a decimal (divide by 100) and multiply it by the sales.

3.5% = 0.035

122,591 x 0.035 = $4,290.69

Answer:

Richard Lens received a commission of $4,290.685 on a sale of  $122,591.

Step-by-step explanation:

We are given the following information in the question:

Total sale made = $122,591

Commission received by Richard = 3.5%

Amount of commission relieved =

Formula:

[tex]\displaystyle\frac{\text{Percentage of Commission recived}}{100}\times \text{Total sales}[/tex]

= [tex]\displaystyle\frac{3.5}{100}\times 122591[/tex]

= $4290.685

Thus, Richard Lens received a commission of $4,290.685 on a sale of  $122,591.

Answer:

The length of the rectangle is 25 km

Step-by-step explanation:

Let

x ----> the length of rectangle

y ----> the width of rectangle

we know that

The perimeter of rectangle is

[tex]P=2(x+y)[/tex]

we have

[tex]P=68\ km[/tex]

so

[tex]68=2(x+y)[/tex]

simplify

[tex]34=(x+y)[/tex]---- > equation A

[tex]x=3y-2[/tex] ---> equation B

substitute equation B in equation A and solve for y

[tex]34=(3y-2)+y[/tex]

[tex]34=4y-2[/tex]

[tex]4y=34+2[/tex]

[tex]4y=36[/tex]

[tex]y=9\ km[/tex]

Find the value of x

[tex]x=3(9)-2=25\ km[/tex]

therefore

7x + 9 ≥ 30

x ≥ 3

Step-by-step explanation:

7x + 9 ≥ 30

7x ≥ 21

x ≥ 3

Final answer:

The inequality 7x + 9 ≥ 30 represents the description given, and the solution is x ≥ 3, meaning any number greater than or equal to 3 satisfies the inequality.

Explanation:

The inequality that represents the description 'nine more than seven times a number (x) is at least thirty' is written as 7x + 9 ≥ 30.

To solve this inequality:

Therefore, the solution to the inequality is that x must be a number greater than or equal to 3.

Among the given options, "-0.1" is not a possible R-value. R-values represent the thermal resistance of a material, and they are always positive values.

R-values are used to measure the ability of a material to resist the flow of heat, and a higher R-value indicates better insulation. Therefore, values like 1.75, 0.2, and -0.5 could potentially be R-values, with 1.75 and 0.2 being good insulators and -0.5 indicating a poor insulator. However, a negative value like -0.1 does not make physical sense in the context of R-values.

Answer:

58,000,000 km

Step-by-step explanation:

the hair thing is just to throw you off

The average distance from the Sun to the planet Mercury is approximately 58 million kilometers, which also translates to 0.39 astronomical units (AU). Mercury's orbit varies from 46 million kilometers at its closest to 70 million kilometers at its farthest from the Sun due to its elliptical orbit.

Distance from the Sun to Mercury

The average distance from the Sun to Mercury is about 58 million kilometers. This distance is known as the semimajor axis of Mercury's orbit. Since Mercury's orbit has a high eccentricity of 0.206, its actual distance from the Sun can vary significantly. The closest point, or perihelion, is about 46 million kilometers, and the farthest point, or aphelion, is about 70 million kilometers. The concept of astronomical unit (AU) is used as a standard measure within the solar system, defined as the average Earth-Sun distance, which is about 150 million kilometers or 1 AU. Consequently, Mercury's average distance from the Sun can also be expressed as 0.39 AU.

a. What percent of people earn less than $40000?

Solution: Let S be the random variable of a salary of employee (in $), S ~ N(50000,20000). Then the random

variable X =−50000

20000

~N(0,1).

( < 40000) = ( <

40000 − 50000

20000 ) = ( < −0.5) = (−0.5) = 0.3085375.

Here Φ(x) denotes the cumulative distribution function of a standard normal distribution.

Answer: 31%.

b. What percent of people earn between $45000 and $65000?

Solution:

(45000 < < 65000) = (

45000 − 50000

20000 < <

65000 − 50000

20000 ) = (−0.25 < < 0.75)

= (0.75) − (−0.25) = 0.7733726 − 0.4012937 = 0.3720789.

Answer: 37%.

c. What percent of people earn more than $70000?

Solution:

( > 70000) = ( >

70000 − 50000

20000 ) = ( > 1) = 0.8413447.

Answer: 84%.

By converting the salary amounts to Z-scores and checking a standard normal distribution table, the percentages of people earning less than $40,000, between $45,000 and $65,000, and more than $70,000 are approximately 30.85%, 37.21%, and 15.87%, respectively.

In this question, we are dealing with what is known as a 'normal distribution' in statistics. The properties of a normal distribution allow us to calculate the percentages requested. First, we need to convert each salary to a 'Z-score'. A z-score will tell us how many standard deviations away from the mean the salary lies.

a) For $40,000, the Z-score will be (40000-50000)/20000, yielding -0.5. Looking up this Z-score in a standard normal distribution table, or using a calculator equipped with normal distribution functions, we find that roughly 30.85% of employees would earn less than $40,000.

b) For the range $45,000 to $65,000: the Z-scores will be -0.25 and 0.75 respectively. These correspond to about 40.13% and 77.34%. The percentage of people earning between these amounts would be 77.34% - 40.13% = 37.21%.

c) For over $70,000: the Z-score is 1.0 which corresponds to around 84.13%. Therefore, the percentage earning more than $70,000 is 100% - 84.13% = 15.87%
