Assume you earn $50,000 /year and contribute 10% of your salary to your 401 K, and your will employer match up to 3% of your salary. What is the total amount you are putting away in your account each year?
Answer:
To calculate the total amount, first find out how much you contribute and then add the amount your employer contributes.
Your contribution: 10% of $50,000
= ($50,000 * 10) / 100
= $5,000
Employer's contribution: 3% of $50,000
= ($50,000 * 3) / 100
= $1,500
Total contribution:
= Your contribution + Employer's contribution
= $5,000 + $1,500
= $6,500
So, the total amount being put away in your account each year is $6,500.

As a unit rate, swimming 16 laps in 1
hour is _____
a. 32 laps per 2 hours
b. 1 lap per 4 minutes
G. 16 laps per hour
d. 8 laps per 30 minutes
Answer:
The correct answer is D., 8 laps per 30 minutes.
Step-by-step explanation:
We can evaluate by making a ratio table:
Our laps are directly proportional to the time spent completing these laps. I will be measuring time in minutes, rather than hours.
laps: minutes
16: 60 *Simplify
8:30
This is also a logical answer statement as 1/2 of 16 is 8, and 1/2 of an hour (60 minutes) is 30 minutes. Therefore, you're completing 8 laps every 30 minutes.

The statement proves the conjecture which is the area of the rectangle ABDE and AB×AE=24 units.
What is the area of the rectangle?The formula for area is equal to the product of the length and breadth of the rectangle. Whereas when we speak about the perimeter of a rectangle, it is equal to the sum of all its four sides.
Given here: The triangle ABDE with AB and AE as the length and AB as the breadth.
Thus the area of the rectangle ABDE= 6×4
=24 units
Thus, The conjecture is True as the rectangle ABDE and the area of the rectangle is equal to 24 units.
Hence, The statement proves the conjecture which is the area of the rectangle ABDE and AB×AE=24 units.

In 2012, a health insurance plan for a 35-year-old and his or her spouse costs $301 per month. That rate increased to $430 per month if a child were included and $538 per month if two children were included. The rate dropped to $269 per month for just the applicant and one child. Find the separate costs for insuring the applicant, the spouse, the first child, and the second child.
Answer: See explanation
Step-by-step explanation:
Let the cost for insuring the applicant = a.
Let the cost for insuring the spouse = b
Let the cost for insuring the first child= c
Let the cost for insuring the second child = d
A 35-year-old health insurance plan and that of his or her spouse costs $301 per month. This means that:
a + b = $301.
That rate increased to $430 per month if a child were included. This means the cost of a child will be:
= $430 - $301
= $129
The rate increased to $538 per month if two children were included. This means the cost for the second child will be:
= $538 - $430
= $108
The rate dropped to $269 per month for just the applicant and one child. His will be the cost of the applicant and a single child. This can be written as:
a + $129 = $269
a = $269 - $129
a = $140
Since a + b = $301
$140 + b = $301
b = $301 - $140
b = $161
Applicant = $140
The spouse = $161
The first child = $129
The second child = $108
Real rate = 1,3%.
in Hation premium = 5%
risk premium at intrest = 1,2%. Q) Calculate nominal intrest of the asset using information given. a) 3,87. b) 2,5%. c) 12, 13%.
d) 7,5%.
The nominal interest rate calculated is 7.5%.
Given that,Real rate = 1.3%Inflation premium = 5%Risk premium on interest = 1.2%.
To calculate nominal interest of the asset using information given we need to use Fisher's Equation and calculate nominal interest rate.
Nominal Interest rate = Real rate + Inflation premium + Risk premium on interest.
Nominal Interest rate = 1.3% + 5% + 1.2%Nominal Interest rate = 7.5%Therefore, the option (d) 7.5% is the correct answer.
Using Fisher's Equation, we calculated the nominal interest rate by adding the real rate, inflation premium, and risk premium on interest. The nominal interest rate calculated is 7.5%.

The first two steps in determining the solution set of the system of equations, y = x2 – 6x + 12 and y = 2x – 4, algebraically are shown in the table.
Which represents the solution(s) of this system of equations?
(4, 4)
(–4, –12)
(4, 4) and (–4, 12)
(–4, 4) and (4, 12)
Answer:
(4,4)
Step-by-step explanation:
The solution set of the system of equations can be found by setting the two equations equal to each other and solving for x.
x^2 - 6x + 12 = 2x - 4
x^2 - 8x + 16 = 0
(x - 4)^2 = 0
x = 4
Since both equations in the system are equal to y, we can substitute x = 4 into either equation to find the corresponding value of y.
y = 2x - 4 = 2(4) - 4 = 4
Therefore, the solution of this system of equations is (4, 4).
Therefore, the correct answer is (4, 4).

Answer:
3x + 2 = 50
16
Step-by-step explanation:
According to the given situation, the equation to determine the number of friends is shown below:-
We assume the number of friends is x
50 - 3x = 2
-3x = -48
3x = 48
x = 16
So, the equation is
3x + 2 = 50
and the number of friends is 16
Therefore, the equation to determine the number of friends we just solved the above equation.

Answer:
y intercept: (0,-13)
x intercept: (13/5, 0)
Step-by-step explanation:
To find the y intercept, x has to equal zero. So, plug it in. The equation becomes y=-13.
Since x is zero, the point becomes (0,-13)
To find the x intercpet, y has to equal zero. So, plug it in. The equation becomes 0=5x-13.
move 13 to the other side
13=5x
divide by 5
13/5=x
Since y is zero, the point becomes (13/5,0)

It takes Sarah 2 hours to make small purses and 3 hours to make big purses. She has a maximum of 18 hours a week. Which inequality represents this situation?
(x: number of small purses made.
y: number of big purses made.)
Answer:
The inequality which represents the solution is: 2x + 3y ≤ 18
Step-by-step explanation:
In the inequality, there are some important words
If the value is at least, that means the sign of inequality is ≥If the value is minimum, that means the sign of inequality is ≥If the value is at most, that means the sign of inequality is ≤If the value is maximum, that means the sign of inequality is ≤∵ The number of small purses = x
∵ Sarah takes 2 hours to make small purses
→ She takes 2x hours
∵ The number of big purses = y
∵ She takes 3 hours to make big purses
→ She takes 3y hours
∴ She takes a total of 2x + 3y hours
∵ She has a maximum of 18 hours a week
→ That means the sign of inequality is ≤
∴ 2x + 3y ≤ 18
The inequality which represents the solution is: 2x + 3y ≤ 18

72°
(7x + 24)
Answer: x ≈ 6.86°
Step-by-step explanation:
Firstly, set them equal to each other:
(7x + 24) = 72°
Subtract 24 from both sides:
7x = 48°
Divide both sides by 7:
x ≈ 6.857...
This can be rounded to:
x ≈ 6.86°
