Answer:
The future value of investment at 6 % compounded quarterly is $ 4782.472
Step-by-step explanation:
Given as :
The principal amount = $ 4000
The rate of interest compounded quarterly = 6 %
The time period = 3 years
Let The future amount = A
From Compounded method
Amount = Principal × [tex](1+\dfrac{\textrm rate}{4\times 100})^{4\times \textrm time}[/tex]
Or, Amount = 4000 × [tex](1+\dfrac{\textrm 6}{4\times 100})^{4\times \textrm 3}[/tex]
Or, Amount = 4000 × [tex](1.015)^{12}[/tex]
Or, Amount = 4000 × 1.195618
∴ Amount = $ 4782.472
Hence The future value of investment at 6 % compounded quarterly is $ 4782.472 Answer

There is a pile of nickles and dimes. The whole pile has 82 coins and is worth 6.75. How many nickles are in the pile?
There are 29 nickles in the pile.
Step-by-step explanation:
Let,
nickles = x
dimes = y
Total coins = 82
Total worth = $6.75 = 6.75*100 = 675 cents
1 nickle = 5 cents
1 dime = 10 cents
According to given statement;
x+y=82 Eqn 1
5x+10y=675 Eqn 2
Multiplying Eqn 1 by 5;
[tex]5(x+y=82)\\5x+5y=410\ \ \ Eqn\ 3[/tex]
Subtracting Eqn 3 from Eqn 2
[tex](5x+10y)-(5x+5y)=675-410\\5x+10y-5x-5y=265\\5y=265[/tex]
Dividing both sides by 5;
[tex]\frac{5y}{5}=\frac{265}{5}\\y=53[/tex]
Putting y=53 in Eqn 1
[tex]x+53=82\\x=82-53\\x=29[/tex]
There are 29 nickles in the pile.

less than the first. Find the three integers.
The three integers are 5,17 and -10
Step-by-step explanation:
Let x, y and z be three integers then
[tex]x+y+z=12 \ \ \Eqn\ 1[/tex]
'The sum of the first and second integers exceeds the third by 32'
[tex]x+y=z+32\ \ \ \ Eqn\ 2[/tex]
The third integer is 15 less than the first.
[tex]z=x-15\ \ \ \ Eqn\ 3[/tex]
From Eqn 2:
[tex]x+y=z + 32\\x+y-z=32[/tex]
Subtracting Eqn 1 from eqn 2
[tex]x+y-z-(x+y+z)=32-12\\x+y-z-x-y-z=20\\-2z=20[/tex]

Answer:
First = 5, second = 17, third = -10
Step-by-step explanation:
First integer = x
The third integer is 15 less than the first, so
Third integer = x - 15
The second integer = y
The sum of the first and second integers exceeds the third by 32, so
The sum of the first and second integers = x + y
The third integer = x - 15
x + y is 32 more than x - 15, hence
x + y - 32 = x - 15
y - 32 = -15
y = 32 - 15
y = 17
The second integer = 17
The sum of three integers is 12, so
x + 17 + x - 15 = 12
2x + 2 = 12
2x = 12 - 2
2x = 10
x = 5
x - 15 = 5 - 15 = -10
a woman is walking at the rate of 90 yards per minute. How fast is she going in feet per second?
Answer:
She is going at the rate of 4.5 feet per second.
Step-by-step explanation:
Given:
The rate of walking is 90 yards per minute.
Now, to find the rate in feet per second.
1 yard = 3 foot.
1 minute = 60 seconds.
So, first we find the rate of walking per second in yard = [tex]90\div 60[/tex]
Therefore by dividing we get = [tex]1.5 yard[/tex]
Now, we find the rate of walking per second in feet = [tex]1.5\times 3[/tex]
So, by multiplying we get = [tex]4.5 feet[/tex]
Therefore, she is going at the rate of 4.5 feet per second.

On a 95-degree day with 80% humidity, the amount of time it takes an air-conditioning unit to cool a 2000-square-foot home 1 degree follows a normal distribution with mean time of 24 minutes and standard deviation of 1 minute. What is the probability it takes an air-conditioning unit longer than 25 minutes to cool the house 1 degree? (Use the Empirical Rule.)
There's a 16% probability that the air-conditioning unit will take longer than 25 minutes to cool a 2000-square-foot home by 1 degree on a 95-degree day with 80% humidity, based on the empirical rule of normal distribution.
Explanation:To find the probability of the air-conditioning unit taking longer than 25 minutes to cool the house 1 degree, you first have to understand that the situation described follows a normal distribution with a mean (μ) of 24 minutes and a standard deviation (σ) of 1 minute.
Using the Empirical Rule, also known as the 68-95-99.7 rule, we can assess probabilities for normal distributions.
According to the Empirical Rule, approximately 68% of the data falls within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations.
Since we are interested in the time more than 25 minutes, we are looking at the area to the right of the mean plus 1 standard deviation (24 + 1 = 25 minutes).
Approximately 68% of the data falls within one standard deviation (between 23 and 25 minutes), so about 34% is below 25 minutes, and another 34% is above. However, we're interested in the portion beyond 25 minutes, falling in the tail.
Because 50% of the distribution falls above the mean (by definition of a normal distribution), and we account for the 34% within one standard deviation above the mean, this leaves us with 50% - 34% = 16% of data points (times in this case) falling beyond 25 minutes on a 95-degree day with 80% humidity.

what is the equation of a line parallel to y-2x=3 that passes through the point (3,1)
Answer:
y = 2x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange y - 2x = 3 into this form by adding 2x to both sides
y = 2x + 3 ← in slope- intercept form
with slope m = 2
Parallel lines have equal slopes, thus
y = 2x + c ← is the partial equation
To find c substitute (3, 1) into the partial equation
1 = 6 + c ⇒ c = 1 - 6 = - 5
y = 2x - 5 ← equation of line

Answer:
314 of the people attending the fun fair are people living in the neighborhood
Step-by-step explanation:
1. Let's review the data given to us for solving the question:
Number of people attending the fun fair = 2,512
Fraction of people attending the fun fair that are students = 5/8
Fraction of people attending the fun fair that are parents = 1/4
Rest of the people attending the fun fair lives in the neighborhood
2. Let's calculate the number of students, parents and people living in the neighborhood
Students:
Fraction of people attending the fun fair that are students = 5/8
5/8 * 2,512 = 1,570
1,570 of the people attending the fun fair are students
Parents:
Fraction of people attending the fun fair that are parents = 1/4
1/4 * 2,512 = 628
628 of the people attending the fun fair are parents
People living in the neighborhood
2,512 - 1,570 - 628 = 314
314 of the people attending the fun fair are people living in the neighborhood

A book has 150 pages and you read 3 pages per day.after a certain number of days,there are 60 pages left.write an equation to show how many days,x,you read
To determine the number of days you have read, an equation is set up as 150 - 3x = 60, where x represents the number of days. After solving, it reveals that you have read for 30 days.
Explanation:To find the number of days, x, that you have read, given that there are 60 pages left and you read 3 pages per day in a 150-page book, we can set up the following equation:
150 - 3x = 60
This equation represents the total number of pages in the book (150) minus 3 pages for each day that you read (3x) equal to the number of pages left (60).
Now, solve for x to determine the number of days you have been reading:
150 - 60 = 3x
90 = 3x
x = 30 days
Therefore, you have been reading for 30 days.

Paul Hastings had a checkbook balance of $1345.00. His bank statement showed a deposit of $423.00 and he hadnt recorded a $15 service fee. What should his checkbook balance be?
Answer:
Paul Hastings checkbook balance be $1753
Explanation:
We are given Paul Hastings
current checkbook balance is equal to $1345.00
and a deposit of $423.00 is said to be made in the bank
so the new balance will be addition of this deposit in the current balance also there's a deduction of $15 as service fee.
So the total checkbook balance will be after subtracting $15 from sum of current balance and deposit.
So his checkbook balance = $1345 + $423 - $15
= $1753
which is the required value of checkbook.
On a certain hot summer's day, 196 people used the public swimming pool. The daily prices are $ 1.50 for children and $ 2.00 for adults. The receipts for admission totaled $ 314.00 . How many children and how many adults swam at the public pool that day?
Number of adults = 40
Number of children = 156
Step-by-step explanation:
Let x be the number of adults and
y be the number of children
Then according to given statements
[tex]x+y=196\ \ \ Eqn\ 1\\2.0x+1.50y = 314\ \ \ Eqn\ 2\\[/tex]
From equation 1:
[tex]x+y = 196\\x = 196-y[/tex]
Putting in equation 2
[tex]2(196-y) + 1.50y = 314\\392-2y+1.50y = 314\\392-0.5y = 314\\-0.5y=314-392\\-0.5y=-78[/tex]
Dividing both sides by -0.5
[tex]\frac{-0.5y}{-0.5} = \frac{-78}{-0.5}\\y = 156[/tex]
Putting y = 156 in equation 1
[tex]x+156 = 196\\x = 196 - 156\\x = 40[/tex]
Hence,
Number of adults = 40
Number of children = 156

What is a polygon?A polygon is a plane figure made up of line segments connected to form a closed polygonal chain. The segments of a closed polygonal chain are called its edges or sides. The points where two edges meet are the polygon's vertices or corners. The interior of a solid polygon is its body.
Given that, what is the name of a 21 sided polygon,
Polygons have very simple names for the first twenty names.
They use a basic prefix naming system. Di, tri, tetra, penta, and so on.
But polygons with 21 to 99 sides have a different naming system.
First, we use a prefix for the tens (such as triaconta—30). Then we use a prefix for the ones (such as di—20).
At last, we put them together with a ‘kai’ between them. This would be formatted to look like (tens)kai(ones)gon.
In simpler words, a 32-sided polygon. We can normally refer to it as a 32-gon.
Hence, the name of a 21 sided polygon is Henicosagon.

If Carrie and Cory add on 18% tip to the bill after tax what does their lunch cost in total
Answer:
The cost of total lunch is 1.18 y ( 1+ 0.0 x )
Step-by-step explanation:
Given as :
The percentage of tip added tot he bill after tax = 18 %
Let the tax added to the bill = x % of total the lunch price
Let The total lunch cost = y
So, The cost of the lunch after tax = y + x % × y
I.e The cost of lunch after tax = y × ( 1 +x % )
Or. The bill of lunch after tax = y × ( 1 + 0.0 x )
Now the cost of lunch after tax and tip =18 % of y × ( 1 + 0.0 x ) + y × ( 1 + 0.0 x )
Or, the cost of lunch after tax and tip = y × ( 1 + 0.0 x ) (0.18 + 1 )
∴ The cost of lunch after tax and tip = y × ( 1 + 0.0 x ) × 1.18
Hence The cost of total lunch is 1.18 y ( 1+ 0.0 x ) Answer
