Answer:
It takes 75 years for the investment to quadruple in value
Step-by-step explanation:
Simple Interest
This is a simple interest problem.
The simple interest formula is given by:
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
In this question:
4% simple interest per year, so I = 0.04.
Quadruple:
t when T = 4P.
The interest earned is:
Now we find the time.
It takes 75 years for the investment to quadruple in value
Answer:
144pi
Step-by-step explanation:
The formula for the volume of a cylinder is base*height
The base of a cylinder is a circle, so it's pi*r^2
r = 6, so pi*r^2 is 36pi
height is 4 so 36pi*4 is 144pi
Answer:
Step-by-step explanation:
First, you distribute the 4 and 7 to the stuff inside the parentheses 28 - 12x = 28 - 14x then add 28 to both sides -12x = -14x then add 14x to both sides 2x = 0 then divide both sides by 2 x = 0
<u>Given</u>:
Given that the radius of the circle is 9 units.
The measure of the angle JHG is 160°
We need to determine the area of the shaded sector of the circle.
<u>Area of the circle:</u>
The area of the circle can be determined using the formula,
where r is the radius
Substituting r = 9 and 
, we get;
Simplifying, we get;
Thus, the area of the shaded sector of the circle is 36π units²
Hence, Option a is the correct answer.
