Answer:
-8^
Step-by-step explanation:
-8^
Step-by-step explanation:
A = A₀ ½^(t / T)
where A is the amount left, A₀ is the original amount, t is time, and T is the half life.
4 days is 96 hours, so the amount left is:
A = 600 ½^(96 / 15)
Angle b is 31
Angle ab is 72
Angle ca is 90+31 so 121
It will be400 divided by 6.88
Answer:
for the area of the Circle we use A=πd
A=3.14x12 A=37.68
for a rectangle it is A=ab
A=12x15 A=180
37.68+180=142.32
your answer is 142.32 m 2
