If the average of six numbers is 18, there sum may be calculated by multiplying this average with 6 which gives us, 108. Three of these numbers have the average of 15. By the same principle, the sum of these numbers is 45. The sum of the remaining numbers in the set may be obtained by subtracting the sum of the three from the total, 108 - 45 which is equal to 63. Thus, the answer is 63.
You can use AA since the parallel lines make corresponding angles congruent.
To solve this, we would divided 1,350 by 6, because the cube has 6 sides and the number 1,350 represents all 6 sides added together. 1,350/6 = 225. Therefore, the answer is 225 ft
Have a nice day :)
Answer:
speed of currnet of river=3 km/hr
Step-by-step explanation:
speed of the boat in still water=15km/hr
speed of the boat in still water for four hour=
=60km/hr
hence speed of currnet of river=63km/hr-60km/hr=3km/hr answer
