Let's assume a,b,c the 3 sides of the triangle.
a=9
b=10
c=24-a-b=5
Answer:
Step-by-step explanation:
Answer: It will take 6 years for 7500 grams of X to reach 6900 grams.
Step-by-step explanation:
Expression for rate law for first order kinetics is given by:

where,
k = rate constant
t = age of sample
a = let initial amount of the reactant
a - x = amount left after decay process
a) for completion of half life:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.


b) for 7500 g to reach to 6900 g


It will take 6 years for 7500 grams of X to reach 6900 grams.
Answer:
B. 624
Step-by-step explanation:
P = ρgh
P = (62.4 lb/ft³) (10 ft)
