Answer:
h ≤ 16
Step-by-step explanation:
If he plans to cook 16 of less hotdogs, h is going to be equal to or less than 16. The circle is closed because he could cook 16.
Answer:
Step-by-step explanation:
You are looking for car b speed.
Car A traveled the distance in 2 h, and Car B traveled the distance in 1.5 h. Car B traveled 15 mph faster than Car A.
Formula r×t=d
2(s-15) = 1.5s
2s - 30 = 1.5s
2s - 1.5s = 30
0.5s = 30
S= 30/0.5
s peed of car b = 60 mph

Answer:
84.96 mg
Step-by-step explanation:
No = 100 mg
t = 6 hours, N = 96% of No = 96 / 100 No
t = 24 hours, N = ?
Let after 24 hours the remaining part is N.
Use the decay law equation
N = No e^-λt
96 / 100 = e^-6λ
0.96 = e^-6λ
taking natural log on both the sides
ln 0.96 = - 6λ
λ = 6.8 x 10^-3 per hour
Now,
N = No e^-24λ
N = No x e^-(24 x 6.8 x 10^-3)
N = No (0.8496)
N = 100 x 0.8496 = 84.96 mg
