Answer:
5.6 days
Step-by-step explanation:
We are given;
Initial Mass; N_o = 25 g
Mass at time(t); N_t = 25/2 = 12.5 (I divide by 2 because we are dealing with half life)
k = 0.1229
Formula is given as;
N_t = N_o•e^(-kt)
Plugging in the relevant values;
12.5 = 25 × e^(-0.1229t)
e^(-0.1229t) = 12.5/25
e^(-0.1229t) = 0.5
(-0.1229t) = In 0.5
-0.1229t = -0.6931
t = -0.6931/-0.1229
t = 5.6 days
Well u would do 64 divided by 4, because there are 4 times as many new bikes as used ones.
the answer is 16 used bikes
Answer:
1000 cm²
Step-by-step explanation:
Given:
- Length = 10 cm
- Width = 12.5 cm
- Height = 8 cm
<u>Formula:</u>

Substitute the length, width, and the height of the prism to determine the volume of the prism.

Simplify the right hand side of the equation, as needed;



Therefore, the volume of the prism is 1000 cm².
it would be a ratio5:6
