Answer:
Hint : They are a all common factors of 5
Step-by-step explanation:
You divide each of them by 5 then add them all together then you will get your answer.
Good luck!
Answer:
Diverge
Step-by-step explanation:
(a)
1st year: 
2nd year: 
3rd year: 
4th year: 
5th year: 
(b) The sequence is divergent, because if we take the derivative of the function with respect to n year:

This is a positive, meaning the slope of the function is positive. If we take the second derivative using product rule

This is also positive when n > 0. Therefore, the slope is positive and increasing. This means the sequence diverges.
The elevator will be on the 76th floor in 60 seconds.
They need 64 pieces for each of them to receive four slices.
#18 Supplementary means two angles add up to 180 degrees. Angles JHF
#19. Complementary means two angles that add up to 90 degrees. Angles GHF
#20. Adjacent means two angles that have a common side and vortex that's why it does not work.
Hope this helps :)
