The answer to your question is 15
Answer: 5/7
Step-by-step explanation:
Just take the square root of the top and the bottom. Square root of 25=5 and the square root of 49=7, so the square root of 25/49=5/7
Answer:
The overall change is $1903.22
Step-by-step explanation:
Let us approach this problem step wise
1.Firstly let us calculate all 12 withdrawal of $175.25
12*$175.25= $2103
2. Let us calculate all the deposits made 17* $235.66 = $4006.22
With these figures we can calculate the overall changes as
= $4006.22-$2103= $1903.22
Answer:
Step-by-step explanation:
c
About 92 days are taken for 90 % of the material to <em>decay</em>.
The mass of radioisotopes (
), measured in milligrams, decreases exponentially in time (
), measured in days. The model that represents such decrease is described below:
(1)
Where:
- Initial mass, in milligrams.
- Current mass, in milligrams.
- Time constant, in days.
In addition, the time constant is defined in terms of half-life (
), in days:
(2)
If we know that 
, 
and 
, then the time required for decaying is:
About 92 days are taken for 90 % of the material to <em>decay</em>.
