Answer:

The mean proportional of 6, and 24 will be 12

Step-by-step explanation:

We know that the Mean proportional of two

numbers, x, and y :  [tex]\sqrt{xy}[/tex]

Therefore, the mean proportional of 6, and 24

[tex]=\sqrt{6\times 24}[/tex]

[tex]=\sqrt{144}[/tex]

[tex]\mathrm{Factor\:the\:number:\:}\:144=12^2[/tex]

[tex]=\sqrt{12^2}[/tex]

[tex]\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a^n}=a[/tex]

[tex]\sqrt{12^2}=12[/tex]

[tex]=12[/tex]

Therefore, the mean proportional of 6, and 24 will be 12.

The statement which best describes the value of the expression at; x = 1 is; Choice D; The result is a whole number that is neither prime nor composite.

It follows from the task content that the value of the expression be determined at; x = 1 and consequently, the result be classified as a whole number, prime number or composite number.

Hence, when x = 1;

5x - 4 = 5(1) - 4.

= 5 - 4

= 1.

Hence, the result is 1 which can be classified as a whole number (integer). However, it is not a prime number and neither is it a composite number.

Therefore, Choice D is correct.

Answer:

60000

Step-by-step explanation:

AFTR 30 YEARS =15000*2=30000

AFTR 60 YEARS=30000*2=60000

First of all, the population is 15,000 NOT 150,00. Do you know why?

After 30 years, 15,000 doubles to become 30,000.

60,000 is twice 30,000.

So, after another 30 years, 30,000 people increases to 60,000.

Answer:

huh what locations

Step-by-step explanation:

Answer:

Above what?

Step-by-step explanation:

Answer: 92 or 119

in 4 months, 2 months with 30 days per month,  2 months with 31 days per month

suppose: the number to find is X

have: 90 < X < 30.2 + 31. 2 ⇔ 90 < X < 122

if X is a number has 2 digits => X is xy

=> [tex]\left \{ {{x+y=11} \atop {90<x\leq 100}} \right.[/tex]

=> xy = 92

if X is a number has 3 digits => X is abc

we have: [tex]\left \{ {{a+b+c=11} \atop {100\leq abc<122}} \right.[/tex]

because 100 ≤ abc < 122 => a = 1; b = 0 or 1

+) if a =1 ,b = 0 but a+ b +c = 11 => c = 10 (removed because c is a 1-digit number)

+) if a = 1, b = 1 => c = 9

=> abc = 119

=> X is 92 or 119

3n-6>5

3n>5+6

3n>11

n>11/3

n>3.6

Answer:

n < 1/3

Step-by-step explanation:

-3(n-2) > 5

-3n + 6 > 5

-3n > 5 - 6

-3n > -1

n > -1/-3 (flip the sign of the inequality because you divided by a negative number)

Hence, n < 1/3 OR n < 0.333

Step-by-step explanation:

The circumcenter is equidistant from all the vertices of the triangle: PV = RV. There are enough dimensions given to let us find RV from the Pythagorean theorem.

  RV² = RS² +SV²

  RV² = 11² +20² = 521

I hope this is good enough:

y-intercept is at positive 2 so you would have +2

it has a negative slope because it is going downwards

Circumference of the wheel is equal to one full rotation

Answer:

1 rotation: 65.312 inches

5 rotations: 326.56 inches

30 rotations: 1959.36 inches

Circumference = π and diameter

3.14 x 20.8 = 65.312 inches

5C = 5 x 65.312 = 326.56 inches

30C = 30 x 65.312 = 1959.36 inches

The required cost of a standard member is $25 as of the given condition.

Given that,
The monthly dues for a premium membership at a health club is $15 more than the cost of a standard membership. The premium membership is $40.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

here,
Let the cost of the standard membership be x,
According to the question,
x = 40 - 15
x = 25

Thus, the required cost of a standard member is $25 as of the given condition.

Answer:

B. [tex]\frac{\sqrt{3}}{11}, \frac{\pi}{24}, \frac{3}{25}, \frac{9}{100}[/tex]

Step-by-step explanation:

The question is not properly presented. See attachment for proper presentation of question

From the attachment, we have that:

[tex]W = \frac{3}{25}[/tex]

[tex]X = \frac{\sqrt{3}}{11}[/tex]

[tex]Y = \frac{9}{100}[/tex]

[tex]Z = \frac{\pi}{24}[/tex]

Required

Order from greatest to least

First, we need to simplify each of the given expression (in decimals)

[tex]W = \frac{3}{25}[/tex]

[tex]W = 0.12[/tex]

[tex]X = \frac{\sqrt{3}}{11}[/tex]

Take square root of 3

[tex]X = \frac{1.73205080757}{11}[/tex]

[tex]X = 0.15745916432[/tex]

[tex]X = 0.16[/tex] --- approximated

[tex]Y = \frac{9}{100}[/tex]

[tex]Y = 0.09[/tex]

[tex]Z = \frac{\pi}{24}[/tex]

Take π as 3.14

[tex]Z = \frac{3.14}{24}[/tex]

[tex]Z = 0.13083333333[/tex]

[tex]Z = 0.13[/tex]  --- approximated

List out the results, we have:

[tex]W = 0.12[/tex]    [tex]X = 0.16[/tex]    [tex]Y = 0.09[/tex]    [tex]Z = 0.13[/tex]

Order from greatest to least, we have:

[tex]X = 0.16[/tex]     [tex]Z = 0.13[/tex]      [tex]W = 0.12[/tex]       [tex]Y = 0.09[/tex]

Hence, the order of arrangement is:

[tex]X = \frac{\sqrt{3}}{11}[/tex]     [tex]Z = \frac{\pi}{24}[/tex]      [tex]W = \frac{3}{25}[/tex]      [tex]Y = \frac{9}{100}[/tex]

i.e.

[tex]\frac{\sqrt{3}}{11}, \frac{\pi}{24}, \frac{3}{25}, \frac{9}{100}[/tex]
