Simple interest is the amount of interest added to a singular sum of money at a fixed rate.
Formula
The formula for simple interest is A = P(1+rt). In this formula, A is the total amount of money in the account, P is the original amount deposited, r is the rate of interest as a decimal, and t is the time in years.
Calculations
To find the rate, plug the information we know into the formula above
Divide both sides by 100
Subtract 1 from both sides
Divide both sides by 5
This gives us the rate as a decimal. So, to find the rate as a percent. Do this by moving the decimal 2 places to the right (or just multiply by 100, they do the same thing). This means that the rate of simple interest is 4.5%.
1/4 divided by 7/1 equals 1/28
There are 1000 grams in a gram and 1000 times 10 is 10000 so yes 100 mg is less than a 10g

Answer:
Step-by-step explanation:
Volume of a right circular cone can be found using the equation
where
- r is the radius of the cone
- h is the height of the cone
- pi is the π constant
Since r=4ft, we can model the volume of the water in the cone in terms of the height as
=
