Answer:
1 hour after they leave
Step-by-step explanation:
The distance each travels is proportional to its speed. The given speeds are at right angles to each other in a 5:12 ratio. The Pythagorean theorem tells you the hypotenuse of such a right triangle will have length ...
√(5²+12²)=√169 = 13
That is the speeds are in the ratio 5:12:13, where 13 represents the relative separation speed. Actual speeds are then 50 mph : 120 mph : 130 mph.
So the distance between the boat and steamer will be increasing at 130 mph. The distance will be 130 miles after 1 hour.
Answer:
It is 9000 cents or $90 total for 5 hours
Step-by-step explanation:
9^2= 9x9= 81. 9^6= 9x9 = 81, 81x9= 729, 729x9= 6561x9= 59049, 59049x9= 531441. So, 81 x 531441 = <span>43046721 :) Hope this helps! Can I get brainliest?</span>
