If $10,000 is deposited into a savings account that pays 1.8% annual interest, how much more would the account be worth if interest were compounded monthly rather than annually over a period of 30 years? Round to the nearest dollar.
Answers
Answer:
Let's first calculate the amount of interest that would be earned if the interest were compounded annually. The formula for the future value of a single sum is:
F = P * (1 + r/n)^(nt)
Where:
F is the future value
P is the principal (the initial deposit)
r is the annual interest rate
n is the number of compounding periods per year
t is the number of years
For our calculation, we have:
P = $10,000
r = 1.8% = 0.018
n = 1 (annual compounding)
t = 30
So, the future value of the account with annual compounding is:
F = $10,000 * (1 + 0.018/1)^(1 * 30) = $10,000 * (1.018)^30 = $21,784.08
Now, let's calculate the amount of interest that would be earned if the interest were compounded monthly. The formula for the future value of a single sum is the same, but we need to use the monthly compounding rate (r/12) instead of the annual rate and the number of months (12t) instead of the number of years:
F = P * (1 + r/n)^(nt)
Where:
F is the future value
P is the principal (the initial deposit)
r is the annual interest rate
n is the number of compounding periods per year
t is the number of years
For our calculation, we have:
P = $10,000
r = 1.8% = 0.018
n = 12 (monthly compounding)
t = 30
So, the future value of the account with monthly compounding is:
F = $10,000 * (1 + 0.018/12)^(12 * 30) = $10,000 * (1.0015)^360 = $22,254.51
The difference in the two future values is $22,254.51 - $21,784.08 = $470.43.
So, the account would be worth $470.43 more if interest were compounded monthly rather than annually over a period of 30 years. Round to the nearest dollar, the answer is $470.

A fraction is a fragment of a whole number, used to define parts of a whole. The whole can be a whole object, or many different objects. The number at the top of the line is called the numerator, whereas the bottom is called the denominator.
The equation for this problem is this:
[tex]\frac{5}{3} + \frac{2}{9}[/tex] (> < =) [tex]1\frac{9}{8}[/tex]First, we need to find a common denominator between [tex]\frac{5}{3}[/tex] and [tex]\frac{2}{9}[/tex].
What is a common denominator?A common denominator consists of two or more fractions that have the same denominator. This makes it easier to perform numeric equations, and to solve them.
To find the common denominator, we can multiply the denominators, 3 and 9.
3 × 9 = 27Now we know that the two new fractions are going to have a denominator of 27.
[tex]\frac{?}{27} \frac{?}{27}[/tex]Now, we can use these equations to solve for the numerator.
9 × 5 = 453 × 2 = 6Now, the fractions look like this:
[tex]\frac{45}{27} \frac{6}{27}[/tex]To add them together, we can use this equation:
[tex]\frac{45}{27}+ \frac{6}{27} = \frac{51}{27}[/tex]Now, we need to convert [tex]1 \frac{9}{8}[/tex] into an improper fraction.
What is an improper fraction?An improper fraction is a fraction that has a numerator that is greater than the denominator. For example, [tex]\frac{3}{2}[/tex] is a improper fraction.
[tex]1\frac{9}{8}[/tex] = [tex]\frac{17}{8}[/tex]To convert [tex]\frac{51}{27}[/tex] and [tex]\frac{17}{8}[/tex] into common denominators, we need to multiply the denominators, like we did above.
8 × 27 = 216The new fractions will look like this:
[tex]\frac{?}{216} \frac{?}{216}[/tex]To solve for the numerators, we can use these equations:
17 × 27 = 4598 × 51 = 408The fractions now look like this:
[tex]\frac{408}{216} \frac{459}{216}[/tex]Now, convert them to mixed numbers.
[tex]\frac{408}{216} = \frac{17}{9}[/tex][tex]\frac{459}{216} = \frac{17}{8}[/tex]Therefore, 5 thirds + 2 ninths < 1 9/8.
in the given figure AB || CD PROVE THAT p+q+r = 180
Answers
As per the figure, the angle equation p + q + r = 180 is proved.
In geometry, an angle is defined as the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. When two lines are parallel, the angles opposite to each other are called corresponding angles.
In the given figure AB || CD, we are asked to prove that the sum of angles p, q, and r is equal to 180 degrees. This can be proven using the concept of corresponding angles.
Since lines AB and CD are parallel, the angles opposite to each other are equal, i.e., p = r. Therefore, the sum of angles p and r can be represented as 2p.
Furthermore, since lines AB and CD are parallel, the alternate interior angles are equal. This means that angle q is equal to angle p.
Therefore, the sum of all three angles, p, q, and r, can be represented as 2p + q.
And since we know that p = q, we can simplify this to 3p.
Finally, since the sum of angles in a triangle is always 180 degrees, we know that
=> 3p = 180 degrees.
Solving for p, we find that p = 60 degrees.
Therefore, the sum of angles p, q, and r is equal to
=> 2p + q = 2 * 60 + 60 = 180 degrees,
which proves the statement p + q + r = 180 degrees.

Help apex!
Answers
D. $128.94. is the total amount of money Nate will earn after taxes when he buys a CD for $1000 The formula for compound interest is:
A = P * (1 + r/n)^(nt), where A is the amount after t years, P is the principal amount, r is the interest rate as a decimal, n is the number of times interest is compounded per year, and t is the number of years.
We can use this formula to calculate the amount of money Nate will have after 5 years:
A = 1000 * (1 + 0.03/4)^(4 * 5) = 1000 * (1 + 0.0075)^20 = 1000 * 1.1629 = 1162.9
The interest earned is 1162.9 - 1000 = $162.9.
And the amount of interest taxed is 20% of $162.9, which is 20% * $162.9 = $32.58.
So, the total amount of interest earned after taxes is $162.9 - $32.58 = $130.32.

Phyllis invested $12,500, a portion earning a simple interest rate of
4 1/5%
per year and the rest earning a rate of 4% per year. After one year the total interest earned on these investments was $518.00. How much money did she invest at each rate
Answers
The interest earned on the x amount at 4 1/5% interest rate can be calculated as x * 4.2 / 100 * 1.
And the interest earned on the ($12,500 - x) amount at 4% rate can be calculated as ($12,500 - x) * 4 / 100 * 1.
The total interest earned after a year is $518, so we can set up the following two equations:
x * 4.2 / 100 * 1 = x * 0.042 * 1
($12,500 - x) * 4 / 100 * 1 = ($12,500 - x) * 0.04 * 1
Adding the above two equations, we get:
x * 0.042 * 1 + ($12,500 - x) * 0.04 * 1 = $518
Expanding and solving for x, we get:
x = $8470
So, Phyllis invested $8470 at 4 1/5% interest rate and $12,500 - $8470 = $4030 at 4% interest rate.

Answer: Let's denote the original number of pages Mark planned to read as "P".
From the first statement, we know that P - 18 pages will take 5 more days, which means P pages will take 5 days less, or 5 - 5 = 0 days.
From the second statement, we know that P - 24 pages will take 8 more days, which means P pages will take 8 days less, or 8 - 8 = 0 days.
So, we have two equations:
P - 18 = 5 * X
P - 24 = 8 * Y
Where X and Y are the number of pages Mark reads per day.
Since X and Y are equal, we can substitute one of them for the other:
P - 18 = 5 * (P - 24) / 8
Expanding the right side and solving for P, we find that P = 288 pages.

Ranger Shoe Company manufactures two types of shoes, athletic shoes and casual shoes. The cost of manufacturing 20 pairs of athletic shoes and 10 pairs of casual shoes is $750. If 25 pairs of athletic shoes and 20 pairs of casual shoes were manufactured, the cost would be $1200. How much does it cost to manufacture each type of shoe?
Answers
The cost of the athletic shoe is $20 meanwhile the cost of the casual shoe is $35.
System of EquationsA system of equations is the given term of math for two or more equations with the same variables. The solution of these equations represents the point of the intersection.
You can solve a system of equations by substitution or adding methods. In the addition method, you eliminate a variable, on the other hand, in the substitution method you replace a variable for the other.
Firstly, you should extract the main information of the question.
Athletic shoes= ACasual shoes = Cfor 20 pairs of athletic shoes and 10 pairs of casual shoes, the total cost is $750for 25 pairs of athletic shoes and 20 pairs of casual shoes, the total is $1200.Next, you should convert the given text information into equations. See below.
20A+10C=750 (1)
25A+20C=1200 (2)
From the substitution method, you can solve this question by following the steps below:
1) Multiply equation 1 by the number -2. Then, you have:
-40A-20C= -1500 (1)
25A+20C=1200 (2)
2) Sum the previous equations presented in step 1.
-15A=-300
15A=300
A=300/15
A=20
3) Find the variable C from equation 2. In step 2, you find A=20, thus.
25A+20C=1200 (2)
25*20+20C=1200
500+20C=1200
20C=1200-500
20C=700
C=700/20
C=35
