Answer:
The required interest rate would be of 3.4% a year.
Step-by-step explanation:
The amount of money earned in compound interest, after t years, is given by:
In which P(0) is the initial investment and r is the interest rate, as a decimal.
Peyton is going to invest $440 and leave it in an account for 5 years.
This means that
So
What interest rate, to the nearest tenth of a percent, would be required in order for Peyton to end up with $520?
This is r for which P(t) = 520. So
Then
The required interest rate would be of 3.4% a year.
Each computer will cost $1,856 and they will have 50 cents left over.
EXPLANATION:
So First you have to add up each total
$1,930( Mr. Datz) + $1,783(Ms. Datz)= $3,713
Then you divide the total by two
$3,713/ 2= 1,856.50
I believe that this is correct. Hope that you get this right! And that my explanation wasn’t too confusing.
It would start like this:
(3x-2) + (2x - 5) + (2x+7)
= 7x

Answer:
6l², where l is the length of one side.
If the side is increased 10 times,
6(10l)²
=100 x6l²
The surface area increases 100 times. Thus, the new surface area is
272 * 100
= 27,200 sq in
