3600 dollars is placed in an account with an annual interest rate of 9%. How much will be in the account after 25 years, to the nearest cent
Using the compound interest formula, the future value of $3600 placed in an account with a 9% annual interest rate after 25 years will be approximately $31042.80.
Calculate the Future Value with Compound Interest
To determine how much will be in the account after 25 years with an annual interest rate of 9%, we will use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A = the amount of money accumulated after n years, including interest.P = principal amount (the initial amount of money) = $3600.r = annual interest rate (decimal) = 0.09.n = number of times the interest is compounded per year = 1 (compounded annually).t = number of years the money is invested or borrowed for = 25.Step by step solution
Substitute the given values into the formula:
[tex]A = 3600 \times (1 + 0.09/1)^(1 \times 25)[/tex]
Simplify the expression inside the parentheses:
[tex]A = 3600 \times (1 + 0.09)[/tex]
Calculate (1 + 0.09) = 1.09.
[tex]A = 3600 \times (1.09)^{25}[/tex]
Raise 1.09 to the power of 25:
[tex]A \approx 3600 \times 8.623[/tex]
Multiply 3600 by 8.623:
[tex]A \approx 3600 \times 8.623 = 31042.80[/tex]
After 25 years, there will be approximately $31042.80 in the account.

Cost of a pretzel is equals to $2.25.
What is system of equations?
" A system of equations is a finite set of equations for which we find the common solution."
According to the question,
'x' represents the cost of pretzel
'y' represents the cost of lemonade
As per situation given system of equation are,
Situation1: The total cost of two pretzels and a lemonade is $5.75, which can be represented by equation:
[tex]2x + y = \$5.75[/tex] ____(1)
Situation2: The total cost of two lemonades is $0.25 more than the cost of a pretzel, which can be represented by equation:
[tex]2y = 0.25 +x[/tex] _____(2)
Multiply equation (1) by 2 we get,
[tex]4x + 2y = \$11.5[/tex] ______(3)
Substitute the value of 2y from (2) in (3) to get the cost of pretzel,
[tex]4x + 0.25 +x = \$11.5[/tex]
⇒ [tex]5x = 11.5 - 0.25[/tex]
⇒ [tex]5x = 11.25[/tex]
⇒ [tex]x =\frac{11.25}{5}[/tex]
⇒[tex]x=\$2.25[/tex]
Hence, cost of a pretzel is equals to $2.25.

jean and mark are going to fill a pool with 2 different sized hoses. Jean can fill the pool in 8 hours, while Mark can complete it in 12 hours. Their supervisor thinks that the job will take 10 hours to complete if they work together. Explain each step in solving the equation, and determine if the supervisor is correct or not.
The number of hours to complete the work together is 4.8 hours.
No, the supervisor is not correct.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 9 is an equation.
We have,
Jean:
Time taken to fill the pool =8 hours
In one hour, 1/8 of the work is done.
Mark:
Time taken to fill the pool = 12 hours.
In one hour, 1/12 of the work is done.
Now,
Together the time is taken to complete the work.
1/8 + 1/12 = (3 + 2)/24
1/8 + 1/12 = 5/24
This can be written as,
1/8 + 1/12 = 1/(24/5)
This means,
The time taken to complete the work together.
= 24/5
= 4.8 hours.
Thus,
The time taken to complete the work together is 4.8 hours.

A. 38x^2
B. [x] 2x^2 (21 – 2pi)
C. 42x^2 – 2pix^2
D. 38pix^2,
Step [tex]1[/tex]
Find the area of the rectangular yard
the area of the rectangular yard is equal to
[tex]A=L*W[/tex]
where
L is the length side of the rectangle
W is width side of the rectangle
in this problem we have
[tex]L=7x\ units\\W=6x\ units[/tex]
[tex]A=L*W[/tex]
[tex]A=7x*6x[/tex]
[tex]A=42x^{2}\ units^{2}[/tex]
Step [tex]2[/tex]
Find the area of a circular fountain
we know that
the area of a circle is equal to
[tex]A=\pi r^{2}[/tex]
where
r is the radius of the circle
in this problem we have
[tex]r=2x\ units[/tex]
substitute
[tex]A=\pi (2x)^{2}[/tex]
[tex]A=4\pi x^{2}\ units^{2}[/tex]
Step [tex]3[/tex]
Find area of the remaining yard
Subtract the area of a circular fountain from the area of the rectangular yard
[tex]42x^{2}\ units^{2}-4 \pi x^{2}\ units^{2}=2x^{2}[21-2\pi][/tex]

Andrew and Ryan spend a total of $44 at a state fair. There is an entrance fee of x dollars per person, and each ride costs $3.50. If they went on the same number of rides, which equation correctly represents this relationship, where n is the number of rides? Choose all that apply.
A. x + 7n = 44
B. 2(x + n) = 44
C. 2(x + 3.5n) = 44
D. x + 3.50n = 44
E. 2x + 7n = 44
F. 2x + 3.50n = 44
Answer:
C. 2(x + 3.5n) = 44
E. 2x + 7n = 44
Step-by-step explanation:
Hi, to answer this question we have to write an equation that represents the situation:
So, the total money spent by the 2 friends is $44. That cost is equal to the price of the entrance fee (x) multiplied by 2 (since they are 2), plus the cost of each ride (3.50) multiplied by the number of rides (n) and also by 2 (since they are 2)
Mathematically speaking:
2(x + 3.5n) = 44
So, the correct options are
C. 2(x + 3.5n) = 44
E. 2x + 7n = 44 (is equivalent, obtained if we apply distributive property to option C.)
