Answer:
66
Step-by-step explanation:
the sum of all exteriors should be 360. so add all of them up and you get 294. then you subtract it from 360 and you are left with the only missing exterior angle, 66.
If AB = 4 inches, AC would equal to 8 inches. The
correct answer between all the choices given is the last choice or letter D. I
am hoping that this answer has satisfied your query and it will be able to help
you in your endeavor, and if you would like, feel free to ask another question.
All you do is add them all together...
20 + 11.4 + 11.4 + 4.5 + 4.5 + 0.45 + 0.45 + 0.45 + 0.45 = 53.6Kg
(note that 0.45 is 450g in Kg, When adding things such as weight or length you want to make sure that they are all in the same unit)
The formula you need is: S = (n/2) (2a1 + (n - 1) x d)
so then you plug in the numbers:
S = (365/2) (2 x 1 + (365 - 1) x 1)
then combine like terms:
S = 66795 pennies
A dollar is 100 pennies. Therefore, at the end of the year, the total savings is $667.95.
