Answer:
The change in available disk space is −6% per episode
Step-by-step explanation:
Given that :
Available disk space changed from 81% to 9% after recording 12 episodes of a show
Each episode requires the same amount of disk space
Change in disk space =
Final % = 9%
Initial percentage = 81%
Change = final value - initial value :
(9 - 81)% = -72%
72% reduction in disk space
Space taken up per episode :
Reduction in space / number of episodes
= -72% / 12
=- 6%
Answer:
P=16+2x
Step-by-step explanation:
The formula for finding the perimeter of a rectangle is P=2l+2w.
Plug the length of 8 and the width of x into the formula.
You'll get P=2(8)+2(x).
Multiply. 2•8=16 and 2•x=2x.
Your expression is P=16+2x.
I hope this helps.
Answer:
25. Yes, it is a function, because none of the x outputs are repeating
Answer:
44%
Step-by-step explanation:
If p represents the number of portions and q represents the quantity in each portion, then the original amount needed was p·q.
After p is increased by 20%, its number is ...
p + 0.20·p = 1.20·p
After q is increased by 20%, its amount is ...
q + 0.20 ·q = 1.20·q
Then the new amount the parents must buy is ...
(1.20p)(1.20q) = 1.20²·pq = 1.44pq
This amount is ...
(1 + 44/100)·pq = pq + 44%·pq
It is 44% more than the original planned purchase.
