l=√121
L=11cm
Answer:
Step-by-step explanation:
60
%
discount given in total, so only
40
%
is paid.
Explanation:
So here we need to make a two-step changing factor.
This means that we first take
0.5
(something decreasing by
50
%
) times
0.8
(something decreased by
20
%
) which is
0.4
(something decreased by
60
%
Answer:
If it does not satisfy the inequality, shade the region which does not contain that point. All the points in the shaded region will satisfy the inequality. Note: The origin (0, 0) is usually the easiest point to test, provided it is not on the line.
Answer:

Step-by-step explanation:
<u><em>Let's check it using Pythagorean Theorem:</em></u>

Where c is the longest sides, a and b are rest of the 2 sides
1) 9 , 40 , 46
=>
=> 
=> 2116 = 81 + 1600
=> 2116 ≠ 1681
So, this is not a Pythagorean Triplet
2) 16, 30 and 34
=> 
=> 
=> 1156 = 256 + 900
=> 1156 = 1156
No need to check more as we've found the one which is not a Pythagorean Triplet.
