You could multiply it by .65 because 95.65 is equal to 61.75.
Answer is .65
Answer: x=27
Step-by-step explanation:
3x-4(4)=65
3x-16=65
3x=65+16
3x=81
3x/3=81/3
X=27
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>.

Answer:
Put 0 in the box.
Step-by-step explanation:
The value x = 0 if replaced in the given equation will always make the denominator zero.

Answer:
x + 100+ 3x = 180
4x + 100 = 180
4x = 180-100
<u>4</u><u>x</u><u> </u> = <u>8</u><u>0</u>
4. 4
x= 20°
