1. 72 to 50 points
50/72 = 69%
100-69= 31% decrease
2. 14 to 40 books
14 / 40 = 35%
100-35= 65% increase
3. 10 plus 30% increase
10 * 0.3 = 13
Answer:
first off you add them all up u get 81 pieces of candy, soooooooooooooooooo you know 9x9 it equals 81 so the answer is 81 and im srry if im wrong :)
Step-by-step explanation:
bc im confident brainliest plss
Answer:
a) 
= 8 in
b) When the length of AC = 
in. and BC = 
in. = 10 in
c) When the length of AB = 10.2 in. and BC = 3.7 in. 
= 6.5 in
d) When the length of AB = 
in. and BC = 
in. in. 
= 
in
Step-by-step explanation:
a) When the length of AC = 5 in. and CB = 3 in. we have;
The length of 
= AC + CB (segment addition postulate)
Therefore;
= 5 in. + 3 in. = 8 in.
b) When the length of AC = in. and BC = in. we have;
The length of = AC + CB (segment addition postulate)
Therefore;
= in.+ in. = 10 in.
c) When the length of AB = 10.2 in. and BC = 3.7 in. we have;
The length of = AB - BC (converse of the segment addition postulate)
Therefore;
= 10.2 in.+ 3.7 in. = 6.5 in.
d) When the length of AB = in. and BC = in. in. we have;
The length of = AB - AC (converse of the segment addition postulate)
Therefore;
= in. - in.= in.
