Hi there!
Since there are 4 columns of boxes fully shaded in and one other box with one section shaded in out of 6 sections, the answer would be
4 + 1 of 6, or
4 1/6.
Hope this helps!
1 month = 5.5cm long
2 month = 7cm long
So 2 months

Step-by-step :
the sum of all angles in the triangle is 180°, So =>
180° = 50° + 60° + x
180° = 110° + x
180° - 110° = x
70° = x
The only solution is when y=y
x+1=x-1 subtract x from both sides
1=-1
This is never true so there are no solutions. In this case it is due to the fact that both lines have the same slope and different y-intercepts. This means that they are parallel lines that have a constant distance between them.
The mass of radioactive material remaining after 50 years would be 48.79 kilograms
<h3>How to determine the amount</h3>
It is important to note that half - life is the time it takes for the amount of a substance to reduce by half its original size.
Given the radioactive decay formula as
m(t)=120e−0.018t
Where
t= 50 years
m(t) is the remaining amount
Substitute the value of t
Find the exponential value
m(t) = 48.788399
m(t) = 48.79 kilograms to 2 decimal places
Thus, the mass of radioactive material remaining after 50 years would be 48.79 kilograms
