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.

The answer for 1.3 (x+y)=
you first multiply 1.3 times x then 1.3 times y so you end up with 1.3x +1.3y
and for the second problem is 2.7d+d+8-6=
(2.7d+d)+(8-6)
3.7d+2
Really bad according to the BLS, the average secondary school teacher in the U.S. earns an annual salary of $56,760. A 40-hour work week employee would have to earn $27.28 per hour to earn as much over the course of a year.
Answer:
line number one is the answer
Answer:
simplify the inequality
40+ 10x≥ 100
step 1 subtract 40 from each side
10x≥60
divide each side by 10,we get
x≥6
we're left with x≥6
as it include 6 and moves towards right
So
the answer is C
