It takes 16,064 years for the 500g of radium to decay to 5g.
<h3>
How long will it take for 500g of radium to decay to 5g?</h3>
Here we have the decay equation:
Where Q₀ is the initial amount, and k is the decay constant.
We know that:
Q₀ = 500g
k = 0.00043
And we want to find the value of t such that Q(t) = 5g, so we need to solve:
Now we can apply the natural logarithm in both sides:
So it takes 16,064 years for the 500g of radium to decay to 5g.

Answer:
$50.45
Step-by-step explanation:
42.75 x 0.18 = 7.695
7.70 + 42.75 = 50.45
E = mc2. An equation derived by the twentieth-century physicist Albert Einstein, in which E represents units of energy, m represents units of mass, and c2 is the speed of light squared, or multiplied by itself.
You need to do 7 divided by 3 so that you get a third of 7 and therefore your answer.
Answer:
The coordinates of every point on the line will solve the equation if you substitute them in the equation for x and y. The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept
