The sides of a quadrilateral are in the ratio 1:2:3:6. The perimeter is 138 cm. Find the lengths of the sides.

11.5cm, 23cm, 34.5 cm, 69cm

Step-by-step explanation:

1+2+3+6=12

138/12=11.5

First side=11.5cm

Second side=11.5x2=23cm

Third side=11.5x3=34.5cm

Fourth side=11.5x6=69cm

how is that middle school

step-by-step explanation:

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
