Poor Luigi (the dog) is stuck in the middle of a very long double L-shaped dock (pictured below). Mario and Dominic can run (on the dock) to get to him or they can each row (on the water) to reach him. Each boy can run at a rate of 5mph. They also row at the same rate. If Mario rows to Luigi, it will take twice the time than if he ran. If Dominic rows to Luigi, it will take 1 /2 the time than if he ran (since he is going downstream). Use the distances for each section of dock noted on the diagram to find the rate that the boys row and the rate of the current. Find rates in mph and round answers to the nearest hundredth.

18 miles is the length they have to row

Step-by-step explanation:

First we have to find the length of the hypotenuse of the first triangle. The equation for the Pythagorean theorem is a²+b²=c²

3²+4²=c²

(3×3)+(4×4)=c²

9+16=c²

25=c²

Now we have to find the square root of 25 (a number times itself that equals 25)

√25=5

Now we do the other triangle

5²+12²=c²

25+144=c²

169=c²

√169=13

All we have to do now is add the lengths

13+5=18 miles

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 %
