5*5= 25 mm
Step-by-step explanation:
5 mm is how many millimeters represents the kilometers.
I hope this helps!
The answer is 28 years
At = A0 * e^(-k * t)
At = 12 g
A0 = 15 g
k = 7.9 × 10^-3 = 0.0079
t = ?
12 = 15 * e^(-0.0079 * t)
12/15 = e^(-0.0079 * t)
0.8 = e^(-0.0079 * t)
Logarithm both sides (because ln(e) = 1:
ln(0.8) = ln(e^(-0.0079 * t))
ln(0.8) = (-0.0079 * t) * ln(e)
-0.223 = -0.0079 * t
t = -0.223 / -0.0079
t = 28.23
t ≈ 28 years
Answer: 5:4
Step-by-step explanation: you divide them i believe :)
31 in total and the smaller one has 13. So just subtract 31-13 and it means there are 18 balls in the larger bag
