The perimeter is 54 m. The apothem is \root(3)(3) . To the nearest tenth, what is the area of this regular polygon?
The area of this regular polygon is 46.8 square units
How to determine the area of this regular polygon?The given parameters are:
Perimeter, p = 54 m
Apothem, a = √3
The area of this regular polygon is then calculated as:
Area = 0.5 * Apothem * Perimeter
Substitute the known values in the above equation
Area = 0.5 * √3 * 54
Evaluate the product
Area = 46.8

45.7 kilometers =
meters
Answer:
45.7 kilometers = 45,700 meters
Explanation:
Hi!
Okay, so basically, in one kilometer, there are 1000 meters.
Using this problem, all you have to do is multiply 45.7 by 1000, which is 45,700.
Whatever value is used for kilometers (ex. 2), just multiply by 1000, and you’ll get the value as meters (ex. 2 x 1000 = 2000 meters).
Hope this helps!
To convert kilometers to meters, multiply the kilometer value by 1000 meters which is equal to 1 km.
Convert 45.7 kilometers to meters:
Knowing that 1000 m = 1 km.[tex]\boldsymbol{\sf{Therefore \ \ \longmapsto \ \ 45.7\not{km}*\left(\dfrac{1000 \ m}{1\not{km}}\right)=45700 \ m }}[/tex]

6. A cube of side 10 cm is melted down

Calculate the surface area of one of the
spheres.
The surface area of the Spheres is 104.19 cm².
According to the statement
we have given that the
there is a cube with side 10 cm and convert into ten spheres and we have to find the surface area of a sphere.
So,
we know that the cube has a 6 sides, each one 10 x 10 cm
So,
A cube with sides of 10 cm will have a surface area of 600 cm².
And The volume of the cube will be 1,000 cm³ ( = 10 x 10 x 10).
If you melt it down to form ten identical spheres, each of them will have a volume of:
1,000 cm³ / 10 = 100 cm³
And the volume of a sphere is:
[tex]V = 4/3 (pi)r ^{2}[/tex]
So you can calculate the radius of the spheres:
r³ = 3V / 4pi = (300) / (12.5664) = 23.8732 cm³
r = 2.8794 cm
Now, you can use the radius to find the surface area of the spheres:
As = 4pi*r² = (12.5664)(2.8794)^2 = 104.19 cm²

The revenue function in terms of q will be 200q - 3q².
How to calculate the revenue?The following can be deduced based on the information given:
P(q) = 200 - 3q
C(q) = 75 + 80q - q²
The revenue function in terms of q will be:
= Price × Quantity
= (200 - 3q) × q
= 200q - 3q²
The profit will be:
= Total revenue - Total cost
= (200q - 3q²) - (75 + 80q - q²)
= 200q - 3q² - 75 + 80q + q²
= -2q² + 280q - 75
= 2q² - 280q + 75
The average cost function will be:
= Total cost / Quantity
= (75 + 80q - q²) / q
= 75/q + 80 - q
The marginal cost will be 80 - 2q.
The marginal revenue will be 200 - 6q.
The marginal cost when q = 20 will be:
= 80 - 2q
= 80 - 2(20)
= 80 - 40
= 40
The marginal revenue when q = 20 will be:
= 200 - 6q
= 200 - 6(20)
= 200 - 120
= 80
The company should decrease production from 20 units in order to gain more profit.
The production level that gives the largest profit for the company will be gotten by finding the second derivative for the profit function as illustrated in the question. The profit function is 2q² - 280q. Then the production level will be 4.

Find the rational roots f(x) =3x3+ 2x2 + 3x + 6
The rational roots of f(x) = 3x^3 + 2x^2 + 3x + 6 are ±(1, 2, 3, 6, 1/3, 2/3)
How to determine the rational root of the function f(x)?The function is given as:
f(x) = 3x^3 + 2x^2 + 3x + 6
For a function P(x) such that
P(x) = ax^n +...... + b
The rational roots of the function p(x) are
Rational roots = ± Possible factors of b/Possible factors of a
In the function f(x), we have:
a = 3
b = 6
The factors of 3 and 6 are
a = 1 and 3
b = 1, 2, 3 and 6
So, we have:
Rational roots = ±(1, 2, 3, 6)/(1, 3)
Split the expression
Rational roots = ±(1, 2, 3, 6)/1 and ±(1, 2, 3, 6)/3
Evaluate the quotient
Rational roots = ±(1, 2, 3, 6, 1/3, 2/3, 1, 2)
Remove the repetition
Rational roots = ±(1, 2, 3, 6, 1/3, 2/3)
Hence, the rational roots of f(x) = 3x^3 + 2x^2 + 3x + 6 are ±(1, 2, 3, 6, 1/3, 2/3)

The Smith family and the Stewart family each used their sprinklers last summer. The water output rate for the Smith family's sprinkler was 25L per hour. The water output rate for the Stewart family's sprinkler was 30L per hour. The families used their sprinklers for a combined total of 65 hours, resulting in a total water output of 1750L. How long was each sprinkler used?
The Smith family's and Stewart family's sprinkler was used 40 and 25 hours.
According to the statement
we have given that the Smith family's sprinkler was 25L per hour and
Stewart family's sprinkler was 30L per hour and The families used their sprinklers for a combined total of 65 hours, resulting in a total water output of 1750L.
And we have to find the How long was each sprinkler used.
So, For this purpose,
The given statements in the equation form become:
Let Smith family's sprinkler be x
Let Stewart family's sprinkler be y then
The equation become
x + y = 65 -(1)
25x + 30y = 1750 -(2)
Here we use the elimination method.
So, Multiply (1) by 25 and (2) by 1 then
25x + 25y = 1625
25x + 30y = 1750
Now eliminate x from the equations then
-5y = -125
y = 25
then x value becomes
x + y = 65
x + 25 = 65
x = 40.
So, The Smith family's and Stewart family's sprinkler was used 40 and 25 hours.

a man borrowed GHC 1200 at the bank for 4 months at the rate of 5%.Calculate a. his simple interest
there are 12 months in a year, so then 4 months is really 4/12 of a year.
[tex]~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\\ P=\textit{original amount deposited}\dotfill & 1200\\ r=rate\to 5\%\to \frac{5}{100}\dotfill &0.05\\ t=\to \frac{4}{12}years\dotfill &\frac{1}{3} \end{cases} \\\\\\ I = (1200)(0.05)(\frac{1}{3})\implies I=20~GHC[/tex]

What is the probability that the mean score for 10 randomly selected people who took the LSAT would be above 157? Round your answer to three decimal places. (Example: 0.398)
Using the normal distribution, there is a 0.007 = 0.7% probability that the mean score for 10 randomly selected people who took the LSAT would be above 157.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].Researching this problem on the internet, the parameters are given as follows:
[tex]\mu = 150, \sigma = 9, n = 10, s = \frac{9}{\sqrt{10}} = 2.85[/tex]
The probability is one subtracted by the p-value of Z when X = 157, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
Z = (157 - 150)/2.85
Z = 2.46
Z = 2.46 has a p-value of 0.993.
1 - 0.993 = 0.007.
0.007 = 0.7% probability that the mean score for 10 randomly selected people who took the LSAT would be above 157.
