Answer:
7306649. 9
Step-by-step explanation:
lets assume length of 2nd piece is x
length of 1 st piece = 2x
length of 3rd piece = 3x - 11
so
x + 2x + 3x-11 = 25
6x -11=25
6x = 25+11= 36
x = 36/6 = 6
so length of 1st peice = 2x = 2×6 = 12
length of 3rd piece = 3x - 11 = 3×6-11
=18-11 = 7
so pieces are 12, 6, 7 inches
Answer:
$153.34
Step-by-step explanation:
Use formula:
where I = Interest
P = Principal
r = rate
t = time
In your case,
P = $1,870
r = 0.0205 (or 2.05% as decimal)
t = 4
I = unknown
Hence,
The formula of the area of a circle is :
You know that the area is 1256.
So :
Divide both sides by
:
<span> take the square root of both sides in order to obtain r :

In short, the answer would be 20 (i have rounded).
Hope this helps !
