The length of a rectangle is twice its width. if the perimeter is 72 meters, find the length and width of the rectangle
madam [21]
Length(l)= 2w
width(w)= w

Perimeter(P)= 2w+2l= 72 (simplify expression: divide each side by 2 )
P= w+l= 36 (plug in "2w" for "l")
P= w+(2w)= 36
P= 3w= 36 (divide each side by 3 to find the width)
w= 12 units

find length:
l=2w
l= 2(12)
l= 24 units

Answer:
The length of this rectangle is 24 units and the width is 12 units.

MilA has a bag filled with marbles in which situations would the probability of mila drawing a blue marbles from the bag be 1-3
Kamila [148]
Since there were no situation given, I can only provide you with some guidance so you can select the correct answer.

If the probability is 1/3, that means that one out of every three options will need to be blue. 

If it is a bag of marbles, you could have 1 blue marble out of a total of 3 marbles. Or any other fraction that reduces to one third.

Here are some examples:

2/6   3/9   4/12   5/15   6/18   7/21   8/24 .....
