What is the correct multiplication of a cross product to solve for the missing dimension?

Step-by-step explanation:

The two rectangles are similar. The shapes are the same but the sizes are different. The ratio of the smaller rectangle to the bigger one is constant.

Comparing the sides of the two rectangles, we would take ratio of the width of both rectangles and equate it to ratio of the lengths of both rectangles. It becomes

3/5 : 12 = x : 20

(3/5)/12 = x/20

3/5 × 1/12 = x/20

3/60 = x/20

Cross multiplying

60 × x = 20 × 3

60x = 60

x = 60/60 = 1

The enlargement is in a scale of 5. Multiplying any length on the smaller rectangle by 5 will give the corresponding length of the bigger

answer: 5000

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 %
