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.
A courier worked 39 hours and earned $429, which included some compensation for paid time off. If his true hourly wage is $3 per hour more than the pay rate shown on his pay stub, what rate is shown on his pay stub?

A. $17 per hour
B. $8 per hour
C. $13 per hour
D. $11 per hour
Answer:
Option B is correct.
Step-by-step explanation:
Number of hours A courier worked = 39
Money a courier earned = $ 429
⇒ Hourly Wage of the courier = [tex]\frac{429}{39}[/tex]
= $ 11 per hour
Let x be the rate shown on his pay stub.
According tot he Question,
x + 3 = 11
x = 11 - 3
x = 8
Therefor, Option B is correct.
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 jumbo tablet in the shape of a rectangle has a perimeter of 50 inches. The tablet is 7 inches less wide than it is long. find the length and width of the tablet. help plzz
Answer:
Length = 16 inches and width = 9 inches
Step-by-step explanation:
The perimeter of a rectangle table = 50 inches
Rectangle table has equal sides of length and equal sides of width.
Let the length of the table be x.
It is given in the question that the table is 7 inches less wide than it is long.
So width of the table = x - 7
Perimeter = 2(length) + 2(width)
Perimeter = 2(x) + 2(x-7) = 50
= 2x + (2)(x) + (2)(-7) = 50
= 2x + 2x + (-14) = 50
= 4x -14 = 50
= 4x = 64
x = 16
Length = 16 inch Width = 16 - 7 = 9 inches
perimeter = 2(16) + 2(9) = 50 inches
9 × 1/5 is the answer greater than or less than 9 and why
The product of 9 multiplied by 1/5 is 1.8, which is less than 9 because multiplying by a fraction between 0 and 1 reduces the original number.
To find the answer, you simply multiply 9 by 1/5. When you multiply a whole number by a fraction less than 1, the product is always less than the original whole number because you are taking a part of it. So, 9 × 1/5 equals 9/5 or 1.8, which is definitely less than 9.
In mathematics, when you multiply a number by a fraction between 0 and 1, the result will be smaller than the original number. This is similar to taking a part of something. On the other hand, when you multiply a number by a fraction greater than 1 or by a whole number greater than 1, the result is greater than the original number because you are effectively adding the number to itself multiple times.
How do you find the range of a rational function with a slant asymptote?
To find the range of a rational function with a slant asymptote, you first find the asymptote by long division. Then by examining the behavior of the function near the vertical asymptotes by plugging in values, you determine the limits of the range. Generally, the range is all real numbers except where interrupted by the asymptotes.
Explanation:To find the range of a rational function with a slant asymptote, you need to first find the slant asymptote by dividing the numerator by the denominator using long division. When you perform the division, if the degree of the numerator is one more than the degree of the denominator, then the quotient (excluding the remainder) will be the equation for the slant asymptote.
Next, you need to explore the behavior of the function on the left and right of the vertical asymptotes, this is done by substituting values just to the left and right of each vertical asymptote into the function and observing the outputs.
If the function approaches negative infinity, the lower limit of the range will be negative infinity. If the function approaches positive infinity, the upper limit of the range will be positive infinity.
So, the range of the function is typically all real numbers except for the values that are 'cut out' by the asymptotes.

To determine the range of a rational function with a slant asymptote, graph the function, analyze for vertical and horizontal asymptotes, discontinuities, and observe its long-term behavior relative to the slant asymptote. The range typically includes all real numbers except for values excluded due to vertical asymptotes or holes.
Explanation:To find the range of a rational function with a slant asymptote, follow these steps:
Graph the rational function to observe its behavior and identify the slant asymptote.Analyze the graph to see where the function's output values (y-values) lie as the input (x-values) become very large or very small.Identify any horizontal or vertical asymptotes, as these will also affect the range.Look for any discontinuities such as holes or vertical asymptotes that might create gaps in the range.Combine all this information to determine the set of all possible y-values the function can attain, remembering that the function will approach but not touch the slant asymptote.Considering the slant asymptote, the function will continue to increase or decrease without bound in at least one direction, unless there is another horizontal asymptote. Therefore, the range can often be all real numbers, except possibly excluding specific values or intervals due to vertical asymptotes or holes.

Jack bought a new set of golf clubs for $186.75. The original price was $249. What percent of the original price did he pay?
Answer:
75% is the percent of which jack payed
Step-by-step explanation:
You can find this out by googling it, or even just using the elimination too. Right away 25% sounded way too low and if you look it up it says that its $68
instead of $186.75. And it can't be any higher than 100% because 186.75 is lower than 249, so that means that 75% is the only reasonable answer

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.)

Velvet fabric costs $1.1.49 a yard. Yvette buys 9.3 yards. Yvette's estimated cost of the velvet is
Answer: $99
Step-by-step explanation:
Yvette's estimated cost for buying 9.3 yards of velvet fabric at $11.49 per yard is approximately $106.86. This is calculated by multiplying the price per yard with the number of yards. An initial rough estimate of $103.50 was also considered before doing a precise calculation.
To calculate the estimated cost of the velvet fabric Yvette buys, you need to multiply the price per yard by the number of yards:
Price per yard = $11.49
Number of yards = 9.3
Estimated cost = $11.49 × 9.3
Let's break it down step-by-step:
First, estimate the two numbers. $11.49 is close to $11.50, and 9.3 is close to 9. Then, multiply: 11.50 × 9 = $103.50.Now calculate more precisely: 11.49 × 9.3 = 106.857 but rounded to two decimal points, it's $106.86.So, Yvette's estimated cost of the fabric is approximately $106.86.
