To calculate the value of the half life we proceed as follows;
a/2=ae^(-2.360t)
the a(s) will cancel and we shall remain with:
1/2=e^-2.360t
introducing the natural logs we get:
ln (1/2)=ln e^(-2.360t)
ln(1/2)=-2.360t
hence;
t=(ln 0.5)/(-2.360)
t=0.294
the answer is t=0.294
The mass of the gold bar is = 13.896 kg.
To acheive this answer you have to multiply the area of the trapezium and the length of the bar. Hope this helped x :)
remember that a mode is a number repeated in the data set ( or the number list.
Mode: 6
What is 32% of 75?
Y is 32% of 75.
Equation: Y = P% * X.
Solving our equation for Y:
Y = P% * X.
Y = 32% * 75.
Converting percent to decimal:
p = 32%/100 = 0.32.
Y = 0.32 * 75 .
Y = 24.
Answer is 24.
