The first step to solve the equation is to add 3 to both sides.
Let width = X
Then length would = 3x
The perimeter is 2 times the length + 2 times the width, so half the perimeter would be the length plus the width.
L + W = 1/2 perimeter
L +w = 48
Replace L and W withe the variables from above:
3x + x = 48
Simplify:
4x = 48
Divide both sides by 4:
x = 48/4
x = 12
Now you have a value for x, replace x with 12 in the variables:
Width = x = 12 cm
Length = 3x = 3*12 = 36 cm
Answer:
Percentage= 72%
Step-by-step explanation:
Giving the following information:
Total population= 2,400
People supporting the local team= 1,728
<u>To calculate the percentage of people supporting the local team, we need to use the following formula:</u>
Percentage= (people supporting / total population)*100
Percentage= (1,728/2,400)*100
Percentage= 72%
That would be a bias sampling because if they are athletes the would probably eat healthy try getting every other person that comes I to the door that day. that would make the sampling unbiased. hope this helped
