Solve attached problem.
find x and y.
you!

Step-by-step explanation:

The attached diagram shows the given triangle labelled as triangle ABC. Line DE is parallel to line AB. It means that triangle DEC is similar to triangle ABC. Comparing the sides,

DC/DE = AC/AB

DC = 5

DE = 8

AC = 5 + x

AB = 10

Therefore,

5/8 = (5+x)/10

Cross multiplying

5 × 10 = 8(5 + x)

50 = 40 + 8x

8x = 50-40 = 10

x = 10/8 = 1.25

Similarly,

CE/DE = CB/AB

CE = 7

CB = 7 + y

DE = 8

AB = 10

Therefore

7/8 = (7+y)/10

Cross multiplying

7 × 10 = 8(7 + y)

70 = 56 + 8y

8y = 70 - 56 = 14

y = 14/8 = 1.75

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 %  

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
