Let the height be h
According to the Pythagoras Theorem,
h= root 15^2-5^2
= root 225-25
= root 200= 14.14
Thus, the ladder reaches approximately 14.14 feet from the base of the house
The answer is 10 days
(after 4 days, they still needed to install 360 chairs, 600-360=240 - meaning they installed 240 chairs in 4 days. to find out how many chairs they installed in 1 day, divide 240 by 4 and you find they installed 60 chairs per day. Then divide 360 by 60 to find the remaining days needed to install the rest of the chairs, which is 6 days then add it onto the 4 days already completed)
Each step subtracts 3 from the previous number.
14 - 3 = 11
11 - 3 = 8
The sequence will continue:
8 - 3 = 5
5 - 3 = 2
2 - 3 = -1
Etc.
14, 11, 8, 5, 2, -1...
