1 cleaning crew = 5 offices in 6 hours
You want to find out the number of offices they can clean in 12 hours
6 (hours) is
of 12 (hours)
The opposite of is 2
6 (hours) multiplied by 2 (opposite of ) is equal to
12
6 x 2 = 12, 12 = the number of offices you're trying to find.
Therefore, you need to multiple 5 by 2 (number that is double), so
5 x 2 = 10
The crew can clean 10 offices in 12 hours

Step 1:
Percent is part of 100.
Step 2
First part:
60 units split into 80% and 20%
Second part
12 units = 40 %
Third part
30 % = 18 units
Fourth part
75 % = 42 units
Final answer
14 + 42 = 56 units
The length of the bottom diagram = 56 units
Answer:
112 m
Step-by-step explanation:
The angle of depression from the pole position is the same as the angle of elevation from the boat position. So, the problem statement gives us an angle and horizontal and vertical legs of a right triangle. The relation between them is given by the tangent function.
Tan = Opposite/Adjacent
If we let (3/4h) represent the length of the side opposite the given angle, and 120 m the side adjacent, we have ...
tan(35°) = (3/4h)/(120 m)
Multiplying by the inverse of the coefficient of h, we get ...
h = (160 m)tan(35°) ≈ 112 m
The height of the pole is about 112 meters.
