Answer:
60.6 cm
Step-by-step explanation:
The perimeter P is the sum of the 4 sides, that is
P = 14.8 + 12.5 + 16.3 + 17 = 60.6 cm
Area of a square = s² [swhere s <span>is the length of one side</span>]
Area = 0.3² = 0.09 m²
Step-by-step explanation:
A = L x W
in multiplication I ignore the decimal points up until I get the answer then add the decimal digits in this case they are two then place the decimal after two digits from the right.
A = 159
x <u> </u><u>91</u>
14469 then place the decimal after two digits from right
= 144.69
Participants = 60
.
First round:
1/3 of 60 = 20
or
60 x 1/3
= 60/3
= 20
60 - 20 = 40
There are 20 participants that are eliminated on the first sound and 40 participants to move on to the second sound.
.
Participants = 40
Second round:
1/4 of 40 = 10
or
40 x 1/4
= 40/4
= 10
40 - 10 = 30
There are 10 participants that are eliminated on the second round and 30 participants that is moving on to the next round.
.
Participants = 30
Third round:
1/6 of 30 = 5
or
30 x 1/6
= 30/6
= 5
30 - 5 = 25
There are 5 participants that are eliminated on the third round and 25 participants to move on to the fourth round.
