Answer:approximately $396,849.46 after 30 years with continuous compounding.
Step-by-step explanation:
To calculate the cost of the loan after 30 years with continuous compounding, we can use the formula for continuous compound interest:
A = P * e^(rt)
Where:
A = the total amount after interest
P = the principal amount (loan amount)
e = Euler's number, approximately 2.71828
r = interest rate per period
t = time in years
Given:
Principal amount (loan amount), P = $175,000
Interest rate, r = 3% = 0.03 (as a decimal)
Time, t = 30 years
Using the formula, we can calculate the total amount (A):
A = $175,000 * e^(0.03 * 30)
Now, let's calculate the cost of the loan after 30 years:
A = $175,000 * 2.71828^(0.03 * 30)
Using a calculator or software, we find:
A ≈ $396,849.46
Therefore, the loan will cost approximately $396,849.46 after 30 years with continuous compounding.
The length of a rectangle is four times its width. If the perimeter of the rectangle is 180 ft, find its area
The area of the rectangle is 1296 square feet.
Let's denote the width of the rectangle as "w" and its length as "4w" since the length is four times the width.
The formula for the perimeter of a rectangle is given by:
P = 2(l + w), where P is the perimeter, l is the length, and w is the width.
Given that the perimeter of the rectangle is 180 ft, we can write the equation as:
180 = 2(4w + w)
Simplifying the equation:
180 = 2(5w)
180 = 10w
w = 18
So, the width of the rectangle is 18 ft.
Now, we can find the length of the rectangle:
Length = 4w = 4(18) = 72 ft
The area of a rectangle is given by the formula:
[tex]A = l \times w,[/tex]
where A is the area,
l is the length,
and w is the width.
Substituting the values we found:
Area [tex]= 72 ft \times 18 ft = 1296 ft^2[/tex]

There are 7 teachers going to the museum. There are 8 times as many students going as teachers. They will need 1 van for every 6 people.
The sentence with proper subject-verb agreement is the student as well as the teacher want to go to the museum. In this sentence, the subject is what we call a compound subject, meaning that the verb refers and agrees with more than just one singular word.
The compound subject is "student" and "teacher" and they are connected by "as well as", which functions as a coordinating conjunction would. That's why the verb should conjugate in its plural form.
Option A is incorrect because the structure inside parentheses is not related to the verb and does not influence its conjugation. Options C and D have a verb in the singular form for a compound subject - that would demand a plural conjugation.

George and Manuel had a roofing business George as owner of the materials received $3 for every $2 manual received on a job that paid $750 what amount did each receive
Manuel received $187.50, and George received $562.50 for the job.
Let's break down the information provided:
The job paid a total of $750.
George received $3 for every $2 that Manuel received.
To determine the amounts George and Manuel received, we can set up a ratio based on their earnings.
Let's assume Manuel's earnings as the base amount:
George's earnings : Manuel's earnings = $3 : $2
We can set up the following equation to solve for Manuel's earnings:
(Manuel's earnings / Manuel's earnings) = ($2 / $2)
Since the ratio is equivalent, we can say:
George's earnings / Manuel's earnings = $3 / $2
To find the amount each person received, we'll assign a variable to Manuel's earnings. Let's call it "x."
Therefore, George's earnings can be represented as "3x."
According to the given information, their total earnings should sum up to $750:
x + 3x = $750
Combining like terms, we have:
4x = $750
To solve for x, we divide both sides by 4:
x = $750 / 4
x = $187.50
Now, we can determine the amounts each person received:
Manuel's earnings = x = $187.50
George's earnings = 3x = 3 * $187.50 = $562.50
Therefore, Manuel received $187.50, and George received $562.50 for the job.

Acylinder has a volume of 400 cubic feet. If the height of the cylinder is 25 feet, what is the radius of the cylinder? Use 3.14 for me and round to the nearest hundredth
adius hype your answer...
1
The radius of the cylinder is 2.25 feet.
To find the radius of the cylinder, we can use the formula for the volume of a cylinder:
V = πr²h
Given that the volume V is 400 cubic feet and the height h is 25 feet, we can substitute these values into the formula and solve for the radius r.
400 = 3.14 r² x 25
Dividing both sides of the equation by (3.14 * 25) to isolate r^2, we have:
r² = 400 / (3.14 x 25)
r² ≈ 5.08
Taking the square root of both sides to solve for r, we get:
r ≈ √5.08
r ≈ 2.25
Therefore, the radius of the cylinder is 2.25 feet.

Find the exact value of cos (-n/12)
The exact value of cos(-n/12) is equal to cos(n/12).
The cosine function (or cos function) in a triangle is the ratio of the adjacent side to that of the hypotenuse.
The value of cosine function is periodic with a period of 2π. Therefore, we can use the property cos(x) = cos(x + 2πk) for any integer value of k.
In this case, we have cos(-n/12). To find the exact value, we can use the fact that cos(x) = cos(-x) for any angle x. Therefore, we can rewrite cos(-n/12) as cos(n/12).
So, the exact value of cos(-n/12) is equal to cos(n/12).

Susan has two solutions that contain alcohol. She uses 100 millileters less of solution a than solution b. Solution A HAS 13% ALCOHOL AND SOLUTION b is 10% alcohol. How many milliliters of solution b is used if the resulting mixture has 102 milliliters of pure alcohol
Susan uses 500 milliliters of solution b to obtain a resulting mixture with 102 milliliters of pure alcohol.
Let's set up the equation based on the given information.
Let x represent the amount of solution b in milliliters.
Since Susan uses 100 milliliters less of solution a than solution b, the amount of solution a is (x - 100) milliliters.
We know that solution a has a concentration of 13% alcohol, which means that for every 100 milliliters, it contains 13 milliliters of alcohol.
Similarly, solution b has a concentration of 10% alcohol, which means that for every 100 milliliters, it contains 10 milliliters of alcohol.
Given that the resulting mixture has 102 milliliters of pure alcohol, we can set up the equation:
0.13(x - 100) + 0.1x = 102
Simplifying the equation, we have:
0.13x - 13 + 0.1x = 102
0.23x - 13 = 102
0.23x = 115
x = 115 / 0.23
x = 500
Therefore, Susan uses 500 milliliters of solution b to obtain a resulting mixture with 102 milliliters of pure alcohol.

00 EXPLANATION
0 0/5
Answer:$0.25
Step-by-step explanation:
To find the expected value of playing the game, we need to multiply the payoff for each possible outcome by its probability and then add up all the values.
Let's first find the probabilities of each outcome:
- Probability of spinning1:1/6
- Probability of spinning2:1/6
- Probability of spinning3:1/6
- Probability of spinning4:1/6
- Probability of spinning5 or6:2/6( or1/3)
Now let's calculate the expected value:
Expected value=(1/6*$1)+(1/6*$3)+(1/6*$5)+(1/6*$7)+(1/3*-$1.25)
Expected value=$0.25
So the expected value of playing the game is$0.25 per spin.
In the long run, Scott can expect to gain money since the expected value is positive. However, this doesn't guarantee that he will actually win money every time he plays the game, as there is still a certain degree of randomness involved in each spin.

The equation that represents this situation is:
⇒ 60t = 0.0284091
where t is the time in minutes.
We have to given that,
The speed of the cheetah is 60 miles per hour
The distance timed was 50 yards
Now, We have to convert the distance to miles, because the speed is in miles per hour.
Since, 1 yard = 0.000568182 miles
Hence, 50 yards = 50 x 0.000568182 miles
50 yards = 0.0284091 miles
Now we can use the formula:
distance = speed x time
We know that,
The distance is 0.0284091 miles, and the speed is 60 miles per hour.
Hence, the time it took the cheetah to run the 50-yard distance.
So, the speed from miles per hour to miles per minute, since we want the time in minutes:
60 miles per hour = 1 mile per minute
Now we can plug in the values we know:
0.0284091 miles = (1 mile per minute) x time
Solving for time:
time = 0.0284091 / 1
time = 0.0284091 minutes
time = 0.0284091 minutes x 60 seconds per minute
time = 1.704546 seconds
Thus, the equation that represents this situation is:

A merchant has 1500 kg of sugar part of which he sells at 8% profit and the rest at 18% profit. He gains 14% on the whole. The quantity sold at 18% profit is
Answer:
900 kg
Step-by-step explanation:
Let's assume the cost price (C.P.) of sugar is Rs. x per kg.
The total quantity of sugar is 1500 kg.
Let the quantity of sugar sold at 8% profit be represented by y kg.
The quantity of sugar sold at 18% profit would then be (1500 - y) kg.
Using the rule of alligation, we can set up the following proportion:
(8% profit) y kg
-------------- = ------
(18% profit) (1500 - y) kg
Simplifying the proportions, we find that the difference in percentages is 4% (18% - 14% = 4%) and 6% (14% - 8% = 6%).
The ratio of these differences is 2:3.
This means that for every 2 kg of sugar sold at 8% profit, 3 kg of sugar is sold at 18% profit.
Since y represents the quantity sold at 8% profit (2 kg), we can calculate the quantity sold at 18% profit (3 kg) as follows:
(2 kg) * (3/2) = 3 kg
Therefore, the quantity sold at 18% profit is 900 kg.

Two walls are 20 feet long and 8 feet tall.
Two walls are 25 feet long and 8 feet tall.
2) Total area to be covered:
= 720 square feet.
3) You will need 1.8 gallons of paint to cover all four walls of the room.
Now, The dimensions of the 4 walls are:
Two walls are 20 feet long and 8 feet tall.
Two walls are 25 feet long and 8 feet tall.
And, The total area to be covered is:
For the two 20 feet long walls:
A = 20 feet x 8 feet
A = 160 square feet each.
And, For the two 25 feet long walls:
A = 25 feet x 8 feet
A = 200 square feet each.
Hence, Total area to be covered:
= (160 + 160 + 200 + 200) square feet
= 720 square feet.
For the number of gallons of paint needed, divide the total area to be covered by the area covered by one gallon of paint:
Number of gallons of paint needed = Total area to be covered / Area covered by one gallon of paint
Number of gallons of paint needed = 720 square feet / 400 square feet per gallon
Number of gallons of paint needed = 1.8 gallons
Therefore, you will need 1.8 gallons of paint to cover all four walls of the room.
