Answer:
Just getting points i hope u find the answer tho :))
Step-by-step explanation:
15 packages of you meant to say 2 1/2
This is a fairly easy half-life problem
Each half-life reduces the radioactive material by one half.
So after 72 hours the radioactive material would have undergone 6 half-lives.
2^6 = 64.
So, there will be one sixty-fourth of the material left.
520 / 64 = 8.125 grams will remain.
radioactive decay is an exponential decay function.

Answer:
Part a :
x = 35
y = 110
z = 35
w = 145
Step-by-step explanation:
Part b :
It is a isosceles triangle so x and z are the same measurements.
It is s triangle so x y z all have to add to 180
in the set of numbers only 35 could work for x and z
if x and z is 35 then y has to be 110 since 35(2) is 70 and 180-70 is 110
w is 145 since z and w are supplementary
180 -35 is 145
