Your answer is: 8x^4 y^5/7.
it's answer is 82 but I think
it will wrong
Answer:
52.7 g
Step-by-step explanation:
We are given;
- Initial mass of the element is 310 g
- Rate of decay 8.9% per minute
- Time for the decay 19 minutes
We are required to determine the amount of the element that will remain after 19 minutes.
We can use the formula;
New mass = Original mass × (1-r)^n
Where n is the time taken and r is the rate of decay.
Therefore;
Remaining mass = 310 g × (1-0.089)^19
= 52.748 g
= 52.7 g (to the nearest 10th)
Thus, the mass that will remain after 9 minutes will be 52.7 g
-9, -8, -7, etc. With positive numbers, greater value is determined by raising the number. However, with negatives, the smaller the number it is (aka the closer it is to 0), the greater value it has. This causes numbers like -1 to be greater than -10. Hope this helps :)
