Answer:
<em>A ≈ 28.5</em>
Step-by-step explanation:
a, b, c
P = a + b + c
Semiperimeter s = 
A = 
~~~~~~~~~~~~~~~
= 4.3 + 2.89 + 6.81 = 14
s = 14 ÷ 2 = 7
= 
= √14.75901 ≈ 3.84
= 8.59 + 7.58 + 6.81 = 22.98
s = 22.98 ÷ 2 = 11.49
= 
= √609.7343148 ≈ 24.6928
= 3.84 + 24.6928 ≈ <em>28.5</em>
I do not think we need to rewrite the first two numbers in the given above because they are already the simplest forms of themselves being whole numbers. However, the third number may be rewritten as 1/2 by dividing both numerator and denominator by 5 and the last one as 2/25 by dividing both numerator and denominator by 4.
Answer:
6 years and 1 month
Step-by-step explanation:
A= Pe^rt
Since you need to find the double A=2P
2P=e^0.1132t
0.1132t=ln 2
0.1132t=0.693
t= 6.12

ps: I think this is right but I'm not sure I had the same problem and I got this.
Answer:
Average = 1
Step-by-step explanation:
Let us define the average first:
Average is calculated by adding up all the values and then dividing the sum by total number of values.
The formula for average may be written as:
In the following case,
Sum of numbers = -3-2+2+2+6 = 5
Count = 5
So,
Average = 5/5
=> Average = 1
