Answer: Length of shorter tree = 7.2 feet .
Step-by-step explanation:
Given : Height of two trees as 50 feet and 20 feet.
At same time the angle made by sun rays would be same for both trees.
Both trees are vertical to the ground making right angle so triangles made by both triangles must be similar.
Corresponding sides of similar triangles are proportional.
So 
So, Length of shorter tree = 7.2 feet .
Change each of the fractions into decimals.
1/8 becomes 0.125
-1/7 becomes -0.143
and -0.02555
0.2
In order from least to greatest,
-0.143, -0.02555, 0.125, 0.2
OR
-1/7, -0.02555, 1/8 and 0.2
The ratio of the probability of that is 3 : 6
Answer:
5 rooms
Step-by-step explanation:
4 rooms = 9 hours
9 hours = 540 minutes
1 room = 540 ÷ 4 = 135 minutes
60 x 12 = 720 minutes (12 hours)
720 ÷ 135 = 5.33333
5.3333 estimated to nearest whole number = 5
So five times five is twenty five. Then do three times fifteen which is forty five.
25+45=70
