A+b=100
a-b=6 ⇒ a= b+6
(b+6)+b=100
2b+6=100
2b=100-6
2b=94
b=94:2
b=47
a=47+6
a=53
Answer:
20 years
Step-by-step explanation:
<u>Continuous Compounding Formula</u>
where:
- A = Final amount
- P = Principal amount
- e = Euler's number (constant)
- r = annual interest rate (in decimal form)
- t = time (in years)
Given:
- A = $10,000
- P = $5,000
- r = 3.5% = 0.035
Substitute the given values into the formula and solve for t:
Therefore, it will take 20 years (to the nearest year) for the initial investment to double.
Answer:
area of a circle is equal to pi × radius square. pi*r^2 ( pi = 3.14 or 22/7)
Answer:
E = number of Ella's stories
A = number of Anna's stories
E = A + 8
if A = 10, then
E = 10 + 8
E = 18
