Therefore , the solution of the given problem of equation comes out to be n = 3.
What is an equation?The same variable word is frequently used in mathematical formulas to attempt to ensure consistency between two assertions. Mathematical equations, also referred to as assertions, are used to demonstrate the equality of many academic figures. Instead of dividing 12 into two portions in this instance, the normalise function adds b + 6 to use the illustration of
y + 6.
Here,
Part 1: We will add 1 to both sides of the equation because we want to separate n in this situation:
=> n - 1 + 1 = 2 + 1
Simplifying:
=> n = 3
Consequently, n = 3 is the answer to the problem n - 1 = 2 when n is taken into account.
To put it up:
=> n - 1 = 2
To both ends, add one:
=> n - 1 + 1 = 2 + 1
Simplify:
=>n = 3
Part 2:
In order to isolate the variable (n) on one side of the equation, we can use inverse operations to answer for n in the equation n - 1 = 2.
Addition is the opposite of reduction. In order to isolate n in this example, we therefore add 1 to both sides of the equation using the inverse process of subtraction.
The steps required are as follows:
=> n - 1 = 2 (original calculation) (original equation)
To both ends, add one:
=> n - 1 + 1 = 2 + 1
Simplify:
=> n = 3

Answers
The savings plan balance after 6 months with an APR of 2% and monthly payments of $150 is approximately $913.35.
What distinguishes nominal interest rates from effective interest rates?The stated interest rate on a loan or investment is known as the nominal interest rate; it does not account for compounding or any other elements that may have an impact on the real return or expense. Often, it is stated as an annual percentage rate (APR).
The effective interest rate, in contrast, takes into account compounding and other elements that may have an impact on the true cost or return of a loan or investment. It is often represented as an annual percentage yield and represents the actual rate of return or cost that is earned or paid on the principal amount over a certain time (APY).
Given that,
APR = 2% and monthly payments = $150.
For future value of annuity we use the following formula:
FV = Pmt × [(1 + r)⁽ⁿ⁻¹⁾] /r
Substituting the values:
r = 0.02/12 = 0.0016667, n = 6, and Pmt = $150:
FV = $150 × [(1 + 0.0016667)⁽⁶⁻¹⁾]/0.0016667
FV ≈ $913.35
Hence, the savings plan balance after 6 months with an APR of 2% and monthly payments of $150 is approximately $913.35.

The length of the hypotenuse (x) in the given right triangle is approximately 10 units.
Hence the correct option is B.
Given is right triangle with perpendicular side having measurement of 5 units,
The acute angle between the base and the hypotenuse = 30°
The acute angle between the perpendicular and the hypotenuse = 60°
We need to find the length of the hypotenuse (x).
We can use the trigonometric ratio for sine (sin) to relate the lengths of the sides.
In this case, we'll use the sine of the 30° angle:
sin(30°) = opposite/hypotenuse
sin(30°) = 5/x
To solve for x, we can rearrange the equation:
xsin(30°) = 5
x = 5 / sin(30°)

Kremena took out a $500 discounted loan for a period of 3 months. The amount she actually received into her bank account was $460. Assuming simple interest rates, what is effective interest rate re?
Answers
The effective interest rate on the loan is also 32%.
What is effective interest rate ?
Effective interest rate is the actual interest rate that is paid or earned on an investment, loan, or other financial product. It takes into account not only the nominal interest rate, which is the stated rate of interest, but also the frequency of compounding or other factors that affect the overall return.
According to the question:
To find the effective interest rate, we first need to calculate the amount of interest Kremena paid on the loan. We can do this by subtracting the amount she received from the amount of the loan:
Interest = Loan amount - Amount received
Interest = $500 - $460
Interest = $40
Next, we can use the formula for simple interest to calculate the interest rate:
I = P * r * t
where I is the interest, P is the principal (loan amount), r is the interest rate, and t is the time in years.
Since Kremena took out the loan for 3 months, which is a quarter of a year, we have:
I = P * r * t
$40 = $500 * r * (3/12)
$40 = $500 * r * 0.25
r = $40 / ($500 * 0.25)
r = 0.32 or 32%
So the interest rate on the loan is 32%. However, this is the nominal interest rate, which does not take into account the effects of compounding. To find the effective interest rate, we need to take into account the fact that Kremena only received $460, which means that she effectively paid more interest than she would have if she had received the full $500.
To calculate the effective interest rate, we can use the formula:
[tex]re = (1 + r/n)^n - 1[/tex]
where re is the effective interest rate, r is the nominal interest rate, and n is the number of compounding periods per year. Since the problem specifies simple interest, there is no compounding, so we can take n = 1. Plugging in the values, we get:
[tex]re = (1 + 0.32/1)^1 - 1[/tex]
re = 0.32 or 32%
So the effective interest rate on the loan is also 32%.

Answers
The radian measure of the angle that forms an arc of length 38 inches in Circle O is approximately 1.9 radians.
What is an angle ?
The length of an arc of a circle is given by the formula:
length of arc = radius * angle in radians
Let x be the radian measure of the angle that forms an arc of length 38 inches in Circle O. Then we can write:
38 = 20x
Solving for x, we get:
x = 38/20
x = 1.9 radians (to the nearest tenth)
Therefore, the radian measure of the angle that forms an arc of length 38 inches in Circle O is approximately 1.9 radians.
What is an arc?
In geometry, an arc is a segment of a curve, such as a circle or an ellipse. It is defined as the portion of the curve that lies between two distinct endpoints. An arc is named based on its endpoints, and it can be classified as a minor arc, major arc, or semicircle depending on its length. A minor arc is an arc that measures less than 180°, a major arc is an arc that measures more than 180°, and a semicircle is an arc that measures exactly 180°. The measure of an arc is typically given in degrees or radians, and it can be calculated using the formula:
measure of arc = (central angle/360) * 2πr
where r is the radius of the circle, and the central angle is the angle that the arc subtends at the center of the circle.

A retailer sold bat at 25% profit. Cost price of 5 bats is equal to cost price of 4 balls. On ball retailer earns 40% profit. If on selling one bat and one ball he earns Rs. 45 profit then find cost price of ball
Answers
The cost price of one ball is equal to Rs. 75
How to evaluate for the cost price of ballWe shall represent the cost price of one bat with the letter 'x', so that the selling price of one bat is 125% of 'x', which is 1.25x.
The cost price of 5 bats is equal to the cost price of 4 balls. So,
5x = 4y, where 'y' is the cost price of one ball.
y = (5/4)x
Also, we know that the profit percentage on one ball is 40%. So, the selling price of one ball is 140% of its cost price, which is 1.4y.
Profit earned on selling one bat and one ball is calculated as:
Profit = Selling price - Cost price
Profit = (1.25x + 1.4y) - (x + y)
Profit = 0.25x + 0.4y
Profit = 0.25x + 0.4(5/4)x {Substituting the value of 'y'}
Profit = 0.75x
given that the above profit is equal to Rs. 45. them,
0.75x = 45
x = 60
The cost price of one bat is Rs. 60 and the cost price of one ball:
y = (5/4)x
y = (5/4) × 60
y = 75
Therefore, the cost price of one ball is Rs. 75.

Here,
We can use the substitution or elimination technique to solve this system. Here, we'll employ the removal strategy.
given solution system:
=> y = 3x + 1 (1)
=>-x + 2y = -3 (2) (2)
By combining equations (1) and (2) multiplied by 1 and 3, respectively, we can remove the variable x:
=>3*(-x + 2y = -3)
=> -3x + 6y = -9
=> 1*(y = 3x + 1)
=> y = 3x + 1
Combining the two equations:
=>y = 3x + 1
=> -3x + 6y = -9
=> 6y - 3x = -8
By multiplying both parts of this equation by 3, we can make it simpler:
=> 2y - x = -8/3
However, we can still use equation (1) to replace y even though we have a new equation in terms of x and y:
=> y = 3x + 1
=> 2y - x = -8/3
y = 3x Plus 1 is substituted in the second equation:
=>2(3x + 1) - x = -8/3
=> 6x + 2 - x = -8/3
=>5x = -14/3
=>x = -14/15

Answers
Answer:
therefore, the expression for John's age in terms of y is 4y - 16.
Step-by-step explanation:
Answer:
John's age = 4y - 16
Step-by-step explanation:
We can start by using the information given to write expressions for the ages of Libby and John in terms of Alfred's age y.
We know that Libby is 4 years younger than Alfred, so her age can be written as:
Libby's age = Alfred's age - 4
We also know that John is 4 times as old as Libby, so his age can be written as:
John's age = 4 × Libby's age
Substituting the expression for Libby's age from the first equation into the second equation, we get:
John's age = 4 × (Alfred's age - 4)
Simplifying this expression, we get:
John's age = 4 × Alfred's age - 16
Therefore, an expression in terms of y for John's age is:
John's age = 4y - 16

Answers
Answer:
Step-by-step explanation:
3.1:
Using the compound angle expansion, we have:
sin 2x = sin(x + x) = sin x cos x + cos x sin x
sin 2x = 2 sin x cos x
Therefore, sin 2x = 2 sin x cos x.
3.2:
Using the result from 3.1:
3.2.1: sin 100° = 2 sin 50° cos 50° = sin 100° = 0.766
3.2.2: sin 46° = 2 sin 23° cos 23° = sin 46° = 0.719
3.2.3: sin 40° = 2 sin 20° cos 20° = sin 40° = 0.642
3.3:
Using the identity sin(a ± b) = sin a cos b ± cos a sin b:
3.3.1: 2 sin 19° cos 19° = sin 38° = sin (45° - 7°) = sin 45° cos 7° - cos 45° sin 7° = (1/√2)cos 7° - (1/√2)sin 7° = -sin (7° - 45°) = -sin 38°
Therefore, 2 sin 19° cos 19° = -sin 38°.
3.3.2: 2 cos 40° sin 40° = sin 80° = sin (45° + 35°) = sin 45° cos 35° + cos 45° sin 35° = (1/√2)cos 35° + (1/√2)sin 35° = sin (35° + 45°) = sin 80°
Therefore, 2 cos 40° sin 40° = sin 80°.
3.3.3: sin 25° cos 155° = (1/2)(sin 180°) = 0
Therefore, sin 25° cos 155° = 0.

5. James Rodriguez strikes a soccer ball during penalty kicks. The arc of the ball can be mapped by the function f(x) = −8t(t – 8). How long does the ball spend in the air?
Answers
Answer:
The function f(x) = -8t(t - 8) represents the height of the soccer ball at any given time t, where t is the time in seconds after the ball was kicked.
To find out how long the ball spends in the air, we need to determine the time at which the ball hits the ground. The ball hits the ground when its height is zero, so we can set f(x) = 0 and solve for t:
-8t(t - 8) = 0
This equation has two solutions: t = 0 and t = 8. The first solution corresponds to the time when the ball is kicked and the second solution corresponds to the time when the ball hits the ground. Since we're interested in the time the ball spends in the air, we need to subtract the time the ball was kicked from the time the ball hits the ground:
t = 8 - 0 = 8 seconds
Therefore, the ball spends 8 seconds in the air.

∴Total cost on posters = ([tex]\frac{2 dollars}{1 poster}[/tex]) × (9 posters)
= $18
Note: The unit multiplier used above is arranged in a way that the current unit of “posters” is cancelled out and the answer is assigned with the new unit of “dollars".
Number of fliers Rhett gives out = x
Printing cost of each flier = $0.20
∴Total cost on fliers = [tex]\frac{0.20 dollars}{1flier}[/tex] × (x fliers)
= $0.20x
Note: The unit multiplier used above is arranged in a way that the current unit of “fliers” is cancelled out and the answer is assigned with the new unit of “dollars”
∴How much it cost Rhett to search for his lost puppy:
y = Total cost on fliers + Total cost on posters
∴[tex]y = 0.20x + 18[/tex]

Compute the limit of the problem in the picture
Answers
Answer:
1/2
Step-by-step explanation:
You want the limit ...
[tex]\displaystyle \lim_{t\to\infty}{\dfrac{t-3}{\sqrt{4t^2+25}}}[/tex]
Solution 1In general, for polynomial-like functions, the limit is the ratio of the highest-degree terms:
[tex]\displaystyle \lim_{t\to\infty}{\dfrac{t-3}{\sqrt{4t^2+25}}} = \lim_{t\to\infty}{\dfrac{t}{\sqrt{4t^2}}}=\dfrac{t}{2t}=\boxed{\dfrac{1}{2}}[/tex]
Solution 2You can consider the limit when x→0 and t=1/x.
[tex]\displaystyle \lim_{t\to\infty}{\dfrac{t-3}{\sqrt{4t^2+25}}} = \lim_{x\to 0}{\dfrac{\dfrac{1}{x}-3}{\sqrt{\dfrac{4}{x^2}+25}}}\\\\\\=\lim_{x\to 0}\dfrac{1-3x}{\sqrt{4+25x^2}}=\dfrac{1}{\sqrt{4}}=\boxed{\dfrac{1}{2}}[/tex]

A two-digit locker combination has two nonzero digits and no two digits are the same. Event A is defined as choosing an odd digit for the first number, and event B is defined as choosing an even digit for the second number.
If a combination is picked at random, with each possible locker combination being equally likely, what is P(B|A) expressed in simplest form?
Answers
The conditional probability is given as follows:
P(B|A) = 1/2, option C.
How to calculate a probability?A probability is calculated as the division of the desired number of outcomes by the total number of outcomes in the context of a problem/experiment.
The events are given as follows:
Event A: odd digit for the first number.Event B: even digit for the second number.P(B|A) is the probability that the second digit is even, considering that the first digit was odd. As the digits cannot repeat, and there will be 8 remaining digits, out of which 4 will be even, the probability is given as follows:
P(B|A) = 4/8 = 1/2.

If the total amount of wealth in the world is $418.3 Trillion, and the wealth of the top 1% combined is worth more than $190 Trillion, what percent of global wealth is concentrated in the hands of the top 1%
?
Answers
Answer: The top 1% of the world's population holds more than 45% of global wealth.
Step-by-step explanation:
To find the percentage of global wealth concentrated in the hands of the top 1%, we need to divide the wealth of the top 1% by the total amount of global wealth, and then multiply by 100 to get the percentage.
Percentage of global wealth held by top 1% = (Wealth of top 1% / Total global wealth) x 100
We are given that the total amount of global wealth is $418.3 trillion, and the wealth of the top 1% is more than $190 trillion.
So, the percentage of global wealth held by the top 1% is:
(190 trillion / 418.3 trillion) x 100 = 45.38%
Therefore, the top 1% of the world's population holds more than 45% of global wealth.
Answer:
45.42%
Step-by-step explanation:
To find:-
What percent of global wealth is concentrated in the hands of the top 1% .Answer:-
We are here given that, the total global wealth is 418.3T dollars and more than 190T dollars is in hands of top 1% of the people. We are interested in finding out the percentage of global wealth in the hands of top 1% . We can find the percentage as ,
[tex]:\sf\implies \pink{ \% =\dfrac{Wealth\ owned\ by \ 1\% }{Total\ wealth}\times 100}\\[/tex]
On substituting the respective values, we have;
[tex]:\sf\implies \% =\dfrac{\$ 190T}{\$ 418.3T}\times 100\\[/tex]

Solving Square Root Equations
Solve the following equations. Be sure to label any extraneous solutions.
Answers
The solution of each equation are;
1) x = 6, x = 0
2) x = 3, x = 2
3) x= 4 ±√6
4) x = 6 ± √24/2
What is an extraneous solution?An extraneous solution is a solution obtained in a mathematical equation that does not satisfy the original equation, even though it appears to be a valid solution when plugged into the equation.
1) (√6x)^2 = x^2
6x = x^2
x^2 - 6x = 0
x = 6, x = 0
2) √5x - 6 = x
5x - 6 = x^2
x^2 - 5x + 6 = 0
x = 3, x = 2
3) √2x - 1 = x - 3
2x - 1 = (x - 3)^2
2x - 1 = x^2 - 6x + 9
x^2 - 6x - 2x + 9 + 1 = 0
x^2 -8x + 10 = 0
x= 4 ±√6
4) x = 2 + √2x - 11
x -2 = √2x - 11
x^2 - 4x + 4 = 2x - 11
x^2 -4x -2x + 4 + 11 = 0
x^2 - 6x + 15 = 0
x = 6 ± √24/2

The answer is A. The game is strictly determined and the value of the game is -7.
What is matrix?A rectangular array of characters, numbers, or phrases arranged in rows and columns is known as a matrix.
Given matrix, where we have to find out, is the game strictly determined for the following matrix or not?
[tex]\left[\begin{array}{ccc}-7&7&-3\\3&8&6\\1&3&-3\end{array}\right][/tex]
Using the minimax theorem, we know that if the game is strictly determined, the value of the game is equal to the value of the saddle point. If the game is not strictly determined, the value of the game may not exist or may be a range of values.
We can check each row and column for minimum and maximum values:
The minimum value in the first row is -7.
The maximum value in the second column is 7.
The minimum value in the third row is -3.
We can see that the element in the first row and second column is both the minimum in its row (-7) and the maximum in its column (7), so it is a saddle point. Therefore, the game is strictly determined and the value of the game is -7.
The answer is A. The game is strictly determined and the value of the game is -7.
