The calculated number of police cadets in the group is 25

From the question, we have the following parameters that can be used in our computation:

Scouts = 8/13

Police cadets = the rest

This means that

Police cadets = 1 - 8/13

Evaluate

Police cadets = 5/13

Also, we have

Prefects = 3/8 or 15 of scouts

This means that

3/8 * Scouts = 15

Scouts = 40

So, we have

Total = 40/(8/13)

Total = 65

Recall that

Police cadets = 5/13

So, we have

Police cadets = 5/13 * 65

Evaluate

Police cadets = 25

Hence, the number of police cadets in the group is 25

Therefore, the trader should sell the article for GHC 4440.00 to make a profit of 48%.

Percent is a way of expressing a number as a fraction of 100. The term "percent" means "per hundred". Percentages are usually denoted by the symbol %, which is placed after the numerical value. Percentages are used in many fields, including finance, science, and everyday life, to represent proportions, rates, and changes in quantities.

Here,

Let's call the original cost of the article "C".

We know that the trader made a profit of 24%, which means that he sold the article for 100% + 24% = 124% of its cost:

124% of C = GHC 3720.00

To find C, we can divide both sides by 1.24:

C = GHC 3720.00 / 1.24

C = GHC 3000.00

So the trader originally purchased the article for GHC 3000.00.

Now we want to know how much the trader should sell the article for to make a profit of 48%. This means that he wants to sell the article for 100% + 48% = 148% of its cost:

148% of C = ?

Substituting C = GHC 3000.00, we get:

148% of GHC 3000.00 = (148/100) x GHC 3000.00

= GHC 4440.00

Answer:

Step-by-step explanation:

Formula

Inscribed angle = Central angle/2

Here

Inscribed angle = x

Central angle = 76

x = 76/2

x = 38

The cost of a croissant before the increase was $0.75, the cost of a cup of coffee was $0.75, and the cost of a fruit bowl was $2.25.

Let's start by assigning variables to the cost of each item before the price increase. Let x be the cost of a croissant, y be the cost of a cup of coffee, and z be the cost of a fruit bowl.

From the problem statement, we know that:

x + y + z = 5.25 (total cost before price increase)

z = 3x (fruit bowl costs 3 times as much as a croissant)

Substituting z = 3x into the first equation, we get:

x + y + 3x = 5.25

4x + y = 5.25

Now we need to solve for x and y. We don't have an equation directly relating the price increase to the new prices, but we can use the percentage increase to write:

New croissant price = x + 0.15x = 1.15x

New coffee price = y + 0.4y = 1.4y

The new total cost will be:

1.15x + 1.4y + z

Substituting z = 3x, we get:

1.15x + 1.4y + 3x

Simplifying this expression and using the equation 4x + y = 5.25 to eliminate y, we get:

1.15x + 1.4y + 3x = 4.15x + 1.4(5.25 - 4x)

4.15x + 1.4(4x - 5.25) = 4.55x - 5.85

Therefore, the new total cost will be $4.55x - $5.85. To find the cost of each item before the increase, we can solve the system of equations:

4x + y = 5.25

z = 3x

Substituting z = 3x into the first equation, we get:

4x + y + 3x = 5.25

7x + y = 5.25

Solving for y in terms of x, we get:

y = 5.25 - 7x

Substituting this expression into the equation for the new total cost, we get:

4.55x - 5.85 = 1.15x + 1.4(5.25 - 4x) + 3x

Simplifying and solving for x, we get:

x = 0.75

Substituting this value of x into the equation for y, we get:

y = 5.25 - 7(0.75) = 0.75

Substituting x and z = 3x into the equation for the total cost before the increase, we get:

0.75 + 0.75 + 3(0.75) = 3.75

Therefore, the cost of a croissant before the increase was $0.75, the cost of a cup of coffee was $0.75, and the cost of a fruit bowl was $2.25.

The probability of Shayla winning the $200 prize with 10 lottery tickets is approximately 0.2753%.

In a probability context, an event refers to an outcome or set of outcomes of an experiment or process. The probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

The probability of winning the lottery can be calculated using the formula:

Probability of winning = 1 / odds

Here, the odds of winning are given as 1-in-3,598. So, the probability of winning is:

Probability of winning = 1 / 3,598

= 0.000278

Shayla has bought 10 lottery tickets. So, the probability of winning the $200 prize with at least one ticket can be calculated as the complement of the probability of not winning with any of the tickets. That is:

Probability of winning with at least one ticket = 1 - Probability of not winning with any ticket

The probability of not winning with a single ticket is 1 - 0.000278 = 0.999722. So, the probability of not winning with all 10 tickets is:

Probability of not winning with all 10 tickets = (0.999722)¹⁰

= 0.997247

Therefore, the probability of winning with at least one ticket is:

Probability of winning with at least one ticket = 1 - Probability of not winning with all tickets

Substituting the given values, we get:

8x - 6 = 180 - (25x - 13)

Solving for x, we get:

33x = 193

x = 193/33

Substituting this value of x in the expression for m∠JML, we get:

m∠JML = 25(193/33) - 13

m∠JML = 1468/3

m∠JML ≈ 489.33°

However, since lines KL and JM appear tangent, we know that minor arc KL and major arc JML share the same endpoint and thus are part of the same circle. So, the actual measure of major arc JML is:

m(arc JML) = 360° - m(arc KL)

We can find m(arc KL) by subtracting m∠KLM from 180°:

m(arc KL) = 180° - m∠KLM

m(arc KL) = 180° - (8(193/33) - 6)

m(arc KL) ≈ 70.67°

Substituting in the formula for m(arc JML), we get:

c. The monthly mortgage payment is $1,027.

a. The down payment is 10% of the home price, which is $225,000 x 0.1 = $22,500.

b. The mortgage is the remaining amount that you need to pay, which is $225,000 - $22,500 = $202,500.

c. The monthly mortgage payment can be calculated using the formula for a fixed-rate mortgage:

Monthly Payment = P [ i(1 + i)^n ] / [ (1 + i)^n – 1]

where P is the principal amount (the mortgage), i is the monthly interest rate (4.5% / 12 = 0.375%), and n is the total number of monthly payments (30 years x 12 months/year = 360).

Plugging in the values, we get:

Monthly Payment = $202,500 [ 0.00375(1 + 0.00375)^360 ] / [ (1 + 0.00375)^360 – 1] = $1,027.

The critical points of the given function f(x) = ** + 5x/ (10x-60) are x = 6 and x = -6/5. The function is decreasing on (-∞, -6/5) and increasing on (-6/5, 6) and (6, ∞). The First Derivative Test shows that x = -6/5 is a local maximum and x = 6 is a local minimum.

To find the critical points, we need to first find the derivative of the function. Using the quotient rule, we get:

f'(x) = (10x - 60)(**)' - **(10x - 60)' / (10x - 60)²

Simplifying, we get:

f'(x) = 50 / (10x - 60)²

The critical points occur where the derivative is zero or undefined. Here, the derivative is never undefined, so we only need to find where it is zero:

50 / (10x - 60)² = 0

This occurs when x = 6 and x = -6/5.

Next, we need to determine the intervals on which the function is increasing or decreasing. To do this, we can use the first derivative test. We test a value in each interval of interest to see if the derivative is positive or negative:

For x < -6/5, we choose x = -2:

f'(-2) = 50 / (10(-2) - 60)² = -5/81 < 0

Therefore, the function is decreasing on (-∞, -6/5).

For -6/5 < x < 6, we choose x = 0:

f'(0) = 50 / (10(0) - 60)² = 5/9 > 0

Therefore, the function is increasing on (-6/5, 6).

For x > 6, we choose x = 10:

f'(10) = 50 / (10(10) - 60)² = 5/81 > 0

Therefore, the function is increasing on (6, ∞).

Finally, we can use the First Derivative Test to determine the nature of the critical points.

For x = -6/5:

f'(-6/5 - ε) < 0 and f'(-6/5 + ε) > 0, for small values of ε.

Therefore, x = -6/5 is a local maximum.

For x = 6:

f'(6 - ε) < 0 and f'(6 + ε) > 0, for small values of ε.

Therefore, x = 6 is a local minimum.

a. The teacher's age in seconds can be written in scientific notation as 1.5 × [tex]10^{9}[/tex] seconds.

b. A more reasonable unit of measurement for this situation could be years, as it is a common unit used to express human age.

c. To convert the teacher's age from seconds to years, we can divide the number of seconds by the number of seconds in a year. There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and approximately 365 days in a year. So,

1.5 × [tex]10^{9}[/tex] seconds ÷ (60 seconds/minute × 60 minutes/hour × 24 hours/day × 365 days/year) = approximately 47.5 years

Therefore, the teacher is approximately 47.5 years old when using the more reasonable unit of measurement.

Solving a direct variation equation to find n gives n = -1

From the question, we have the following parameters that can be used in our computation:

A direct variation includes the points (2, –10) and (n,5).

This means that

(2, –10) = (n,5)

Express as an equation

So, we have

-2/10 = n/5

Multiply both sides of the equation by 5

So, we have the following representation

n = -2/10 * 5

Evaluate the product

n = -1

Hence, the value of n in the equation is -1
