D) The percentage of dresses that are not for films set during the civil war era is 85%.
What is a percentage?
The percentage is a way of expressing a number as a fraction of 100. It is often denoted using the symbol "%". It is used to express a proportion of a number out of 100. It is useful in many applications such as finance, statistics, and other fields.
A. Three-fifths of the dresses can be used for movies that take place in the 1700s, which is 3/5 * 100 = 60%.
B. The percent of the dresses that are not for films set in the 1700s is 100% - 60% = 40%. This is found by subtracting the percentage of dresses that are used for 1700s movies from 100%.
C. The percent of the dresses that can be used for films set in the 1700s or during the civil war era is 60% + 15% = 75%. This is found by adding the percentage of dresses that can be used for 1700s movies and the percentage of dresses that can be used for civil war era movies.
D. The percent of the dresses that are not for films set during the civil war era is 100% - 15% = 85%. This is found by subtracting the percentage of dresses that are used for civil war era movies from 100%.
Hence,
A) The dresses for films set in the 1700s would be 60%.
B) The percentage of dresses that are not for films set in the 1700s is 40%.
C) The percentage of dresses that can be used for films set in the 1700s or during the civil war era is 75%.

Pacquiao has inherited P6,000 from the death of his Grandma . He would like to use this money to buy his mom Dionisia a new bicycle costing P7,000 2 years from now. Will Pacquiao have enough money to buy the gift if he deposits his money in an account paying 8 percent compounded semi-annually?
Pacquiao will have enough money (a future value of up to P7,000) to buy the gift if he deposits his money (P6,000) in an account paying 8 percent compounded semi-annually.
What is the future value?The future value is the compounded present value at an interest rate.
The future value can be determined using an online finance calculator, FV table, or FV formula.
N (# of periods) = 4 (2 years x 2)
I/Y (Interest per year) = 8%
PV (Present Value) = P6,000
PMT (Periodic Payment) = P0
Results:
Future Value (FV) = P7,019.15
Total Interest = P1,019.15
Thus, in 2 years' time, Pacquiao will have P7,019 enough to buy his mom a new bicycle.

Timothy bought a house for $360,000. He paid 20% down, and agreed to pay $1,375.69 per month for 30 years. His payment of $1,375.69 does not include property tax and insurance. How much interest will Timothy pay in 30 years?
It's difficult to determine exactly how much interest Timothy will pay over 30 years without more information about the terms of his mortgage. However, we can use the following formula to calculate his monthly mortgage payment, which includes both the principal and the interest:
Monthly payment = P * (r/12) / (1 - (1 + r/12)^(-n))
Where:
P is the principal amount (the total cost of the house minus the down payment)
r is the monthly interest rate (we need to convert the annual interest rate to a monthly rate by dividing it by 12)
n is the number of payments (in this case, the number of months over which Timothy will pay off the mortgage, which is 30 years * 12 months/year = 360 months)
We can plug in the given values to find Timothy's monthly payment:
Monthly payment = $360,000 * (0.04/12) / (1 - (1 + 0.04/12)^(-360)) = $1,375.69
To find the total amount of interest Timothy will pay over 30 years, we would need to know the interest rate on his mortgage and the length of the loan in months. With this information, we could calculate the total amount of interest Timothy will pay by multiplying his monthly payment by the number of payments he makes (360 payments in this case) and subtracting the principal amount ($360,000).
