Let x = the other rational number.
x(66/7) = (48/5)
Solve for x to find your answer.
We know that
<span>This problem can be represented through the following equation
</span>
A = A₀(1/2)^t/h
where
A-----------> is the amount of substance left after time t
A₀ ----------> is the original amount---------> 2 g
h-------------> is the half-life-----------> 8 days
for A=0.04 g
t=?
0.04 = 2(1/2)^t/8
0.02 = (1/2)^t/8
Take ln on both sides:
ln(0.02) = ln [(1/2)^t/8]
ln(0.02) = (t/8)(ln 1/2)
t = 8*ln(0.02)/ln(1/2)
t = 45.15 days
the answer is 45.15 days
Answer:
18a +9
Step-by-step explanation:
9(2a+1)
The first step is to distribute the 9
9*2a+9*1
18a +9
Answer:
B. figure made up of 2 or more basic shapes
hope this helps :)
8*(1/x) = 4*(1/8)
8/x = 4/8
64 = 4x
x = 16
