➷ Work out the original area:
(5 x 18) / 2 = 45cm^2
Increase/decrease the changed values:
18 x 0.7 = 12.6
5 x 1.2 = 6
New area:
(12.6 x 6) / 2 = 37.8cm^2
Calculate percentage change:
((45 - 37.8) / 45) x 100 = 16
16% decrease

Answer:
Option D is correct.
Explicit formula for the geometric sequence is, 
Step-by-step explanation:
Geometric sequence states that a sequence of numbers in which the ratio between consecutive terms is constant,
we can write a formula for the nth geometric sequence in the form of:
.....[1] where 
is the first term and r is the common ratio between successive term.
Given the sequence: 64, 32, 16 , 8......
Here, first term () = 64.
Common ratio(r) = 0.5
Since,
,
......
Substitute the value of a and r in [1] we get;
therefore, the explicit formula for the geometric sequence is,

Answer:
12 Pencils Sharpened
Step-by-step explanation:
Since the sharpener receptacle is emptied out 2 times every day.
Do 24*2 to get 48 pencils sharpened each day.
Now do 48/20 to get how many pencils a single person sharpens each day. Resulting in 2.4 pencils each day for 1 person.
Multiple 2.4 by 5 (Amount of days) to get 12 pencils in 5 days.
