A coastal town with 4,500 inhabitants has the fraction of 1,200 working in the service sector, which represents approximately 26.67% of the total population.

One third of the population works in fishing, which is equal to

(1/3) x 4,500 = 1,500 inhabitants

Two fifths work in agriculture, which is equal to

(2/5) x 4,500 = 1,800 inhabitants

The remaining inhabitants work in the service sector, which is equal to

4,500 - 1,500 - 1,800 = 1,200 inhabitants

To find the fraction of inhabitants who work in the service sector, we can divide the number of inhabitants who work in the service sector by the total population

1,200 / 4,500 = 0.2667 or 26.67%

Therefore, there are 1,200 inhabitants working in the service sector, which represents approximately 26.67% of the total population.

Answer:

112ft

Step-by-step explanation:

To find the total surface area, we need to find the area of each face of the shape and add those area together.

So, for the rectangular faces, we multiply 4 by 8 to get 32.

For the triangle faces, we multiply 4 by 4 and divided by 2 which is 8. We can use the equation base*height/2 because  the 4ft lengths form a right angle, meaning four is the base and height.

There are three rectangular faces, and two triangular faces, so

(3*32)+(2*8)= 112 ft

Step-by-step explanation:

In order to find b use sin

Sin (30) = b/46

Sin (30) = b/46b = sin (30) × 46

Sin (30) = b/46b = sin (30) × 46b = 1/2 × 46

Sin (30) = b/46b = sin (30) × 46b = 1/2 × 46b = 23

If the angle bisector of angle M also bisects side LN, then we can conclude that triangle LMN is an isosceles triangle.

Let the angle bisector of angle M cross LN at point P to show why this is true. We know from the angle bisector theory that LP/PN = LM/MN. Because LP = PN, LM = MN, which indicates that triangle LMN has two equal sides (LM = MN) and is thus an isosceles triangle.

A triangle with two equal sides and two equal angles is called an isosceles triangle. The two equal angles are opposite the equal sides and are known as the basis angles.

The angle bisector of the vertex angle (the angle opposite the equal sides) likewise bisects the base, dividing it into two equal segments.

Using the Principle of permutations it is found that, there are 720 ways in which the horses can finish in first, second, and third place.

This is an example of a permutation problem, where we are interested in the number of ways to order a set of objects.

In this case, we have 10 horses racing at the championship, and we want to determine how many ways they can finish in first, second, and third place.

To solve this problem, we can use the permutation formula:

P(n, r) = n! / (n - r)!

where n is the total number of objects and r is the number of objects we want to choose and arrange in order.

In this case, we want to choose 3 horses from 10 to finish in a particular order. Therefore, we have:

P(10, 3) = 10! / (10 - 3)!

= 10! / 7!

= 10 x 9 x 8

= 720

Answer:

The answer is A, you have to simplify in order to solve this equation.

Answer:

x-intercept (10, 0)

y-intercept (0, -6)

Step-by-step explanation:

The x-intercept is where y = 0. Thus, set y as 0 to find the x-intercept:

3x - 5(0) = 30

3x - 0 = 30

3x = 30

x = 10                         The x-intercept is (10, 0)

The y-intercept is where x = 0. Thus, set x as 0 to find the y-intercept:

3(0) - 5y = 30

0 - 5y = 30

-5y = 30

y = -6                           The y-intercept is (0, -6)

Answer: (10,0) and (0,-6)

Step-by-step explanation:

To find the y intercepts we solve the equation for when x=0. So we have 3(0)-5y=30 which reduces to -5y=30. Divide -5 on both sides and get y=-6. Therefore, the y intercept is (0,-6). To find the x intercept plug 0 in for y. Then you get x=10, so the x intercept is (10,0).

If the lawyer Carson decides to charge 20% less in the rate of $369 per hour, then the new amount that Carson charge per hour will be $288.

The per-hour rate of the lawyer Carson is = $360,

To find new-rate, we convert the percentage 20% to a decimal which is 0.2,

We multiply the previous rate of $360 by 0.2 to get the amount of the reduction:

⇒ $360 × 0.2 = $72,

So, Carson has reduced his rate by $72 per hour.

To find the new rate, we subtract reduced-rate from the previous-rate:

We get,

⇒ $360 - $72 = $288,

Therefore, Carson's "new-rate" is $288 per hour.

We have the values of a and b, so let's substitute:

[tex]x^{2} =4(4+5)[/tex]

evaluate the right side

[tex]x^{2} =36[/tex]

take the square root of both sides

x=6

Hope this helps!

Answer:

x=6

Step-by-step explanation:

To solve this problem, you first have to use the formula for this problem. The formula is [tex]b(a+b)=c^2[/tex]. The b in this formula is four or the part of the secent outside the circle, while the a is the line in the middle of the circle, which is 5. The C would be the x because the c is always the tangent of the circle.

So let us substitute the values (this will require quite a bit of algebra).

[tex]b(a+b)=c^2\\\\4(5+4)=x^2\\\\4(9)=x^2\\\\36=x^2\\\\\sqrt{36}=\sqrt{x^2}\\\\6=x[/tex]

(We had to take the square root of both sides to isolate x, this type of problem is called a perfect square binomial.)

The mean and the standard deviation of the sampling distribution of the sample mean  is equal to 4.57 and 0.69 respectively.

Population mean  'μ' = 4.57

Sample size 'n' = 7

Population Standard deviation 'σ' =1.82

Mean of the sampling distribution of the sample mean is equal to the population mean,

which is μ = 4.57.

So, μₓ = μ = 4.57.

Standard deviation of the sampling distribution of the sample mean also known as the standard error of the mean.

Using the formula we have,

σₓ = σ / √(n)

Substituting the given values, we have,

⇒ σₓ = 1.82 / √(7)

⇒ σₓ = 1.82 / 2.646

⇒ σₓ = 0.6878

⇒ σₓ ≈ 0.69

This implies,

The standard deviation of the sampling distribution of the sample mean is σₓ ≈ 0.69.

Answer:

The correct answer is x = -7 and x = 1. To solve this equation using the completing the square method, we first need to subtract 13 from both sides of the equation. We then need to add 49/4 to both sides of the equation. This gives us (x + 7/2)^2 = 49/4. We then take the square root of both sides of the equation to get x + 7/2 = 7/2 or x = -7. We can then solve for the other value of x by subtracting 7/2 from both sides of the equation, giving us x = 1.

According to unitary method, the total number of fruits in the basket is (8/7) times the difference between the total number of fruits and 5.

To find out the total number of fruits in the basket, we need to add up the number of apples, bananas, and oranges. So, the equation we can use is:

total fruits = number of apples + number of bananas + number of oranges

total fruits = 5 + (5/8)x + (1/4)x

Notice that we used "x" to represent the total number of fruits. Now we can simplify the equation by finding a common denominator for the fractions:

total fruits = 5 + (5/8)x + (2/8)x

total fruits = 5 + (7/8)x

So, we have an equation for the total number of fruits in the basket in terms of "x". To solve for "x", we can subtract 5 from both sides of the equation:

(7/8)x = total fruits - 5

And then, we can multiply both sides by 8/7 to isolate "x":

x = (8/7)(total fruits - 5)

Ryan thus walked a distance of 1.8375 miles.

Let d be the distance between Ryan's house and his friend's house.

According to the problem, Ryan went to his friend's house at a speed of 3 miles per hour, which equals d/3 hours.

Ryan rode his bike home at 7 miles per hour, which meant it took him d/7 hours.

We can use the following equation because the round trip took 1.75 hours:

d/3 + d/7 = 1.75

To calculate d, first, simplify the equation by locating a common denominator:

(7d + 3d) / (3 x 7) = 1.75

10d / 21 = 1.75

When we multiply both sides by 21, we get:

10d = 1.75 x 21

10d = 36.75

When we divide both sides by 10, we get:

d = 3.675

The distance between Ryan's residence and his friend's house is thus 3.675 miles. Ryan walked to his friend's house and returned home on the same route, thus he walked the same distance as he rode the bike, which is d/2 = 1.8375 miles.

In the given polygon, the sides of AVWX in order from longest to shortest is XV, WX, VW (option c)

To determine the order of sides from longest to shortest, we need to use the fact that the longest side is opposite the largest angle, and the shortest side is opposite the smallest angle. Therefore, we need to determine which sides are opposite the largest and smallest angles.

We are given that m/V = 96°, which means that angle V is the largest angle in the quadrilateral. Therefore, side XV is opposite the largest angle and is the longest side.

Similarly, we are given that m/W = 39°, which means that angle W is the smallest angle in the quadrilateral. Therefore, side WX is opposite the smallest angle and is the shortest side.

Now we need to determine the order of the remaining sides, which are AV and VW. To do this, we need to use the fact that the sum of the measures of angles in a quadrilateral is always 360°. Therefore, we can find the measure of angle A by subtracting the sum of the other three angles from 360°.

m/A = 360° - (m/V + m/W + m/X) = 360° - (96° + 39° + m/X)

We don't know the measure of angle X, but we know that it must be between 0° and 180° since it is an interior angle of a quadrilateral. Therefore, we can set up an inequality to find the maximum and minimum values of angle A.

0° < m/X < 180°

96° + 39° < 360° - m/A < 96° + 39° + 180°

135° < 360° - m/A < 315°

225° < m/A < 45°

Since angle A is between 225° and 45°, we know that side AV is longer than side VW. Therefore, the order of sides from longest to shortest is:

XV, WX, AV, VW

Hence the correct Answer is C. XV, WX, VW
