Given:
The initial mass of an element is 800 grams.
Decay rate = 8.2% per day
Number of days = 15
To find:
The remaining element after 15 days.
Solution:
The exponential decay model is

Where, a is the initial value r is the rate of interest and t is time period.
Putting
in the above formula, we get




Therefore, the mass of the remaining element is 221.7 grams.
Answer:
Step-by-step explanation:
I think this is it but you question want super clear
A = C/2r
Answer:
0.8 lbs
Step-by-step explanation:
Ounces are typically used to measure liquid, so I would discourage choosing the top two. And, hopefully you know by now that an orange does not weigh 8 pounds.
Answer:
are you sure this is high school level stuff? its 9% of 100
Step-by-step explanation:
To compare both, we find the volume of both cubes as follows:
V of cube A = 10 g / 10 g/cm^3 = 1 cm^3
V of cube B = 10 g / 0.37 g/cm^3 = 27 cm^3
I think the correct answer from the choices listed above is option D. Each edge of cube b is three times larger than cube. Hope this helps. Have a nice day.
