Given that the half-life of the sample is 14.28 days, you are looking for a decay factor
such that
Solving for
yields
Now, after 57 days, you're told that a sample of unknown mass decayed to 55g, which means if
was the starting mass of the sample, then
Solving for
yields
Answer:
PQR is an equilateral triangle because its sides are equal. ... Since radius of the incircle is equal to the side length of the hexagon, all sides of the triangle are equal, thus, creating an equilateral triangle. I hope this helped.

Step-by-step explanation:
Answer:
y = 9
Step-by-step explanation:
the two sides are balancing so that means one 'x' and three 'y' equals four 'x' plus one 'y'
x + 3y = 4x + y
subtract 'x' from each side to get:
3y = 3x + y
subtract 'y' from each side to get:
2y = 3x
if 'x' = 6 then:
2y = 3(6)
2y = 18
y = 9
Answer: c
Step-by-step explanation:
Answer:
da answerr is six
if DF is 6 and all sides are equal in length the EF side is going to be 6 as well
