Answer:
4000 units
Step-by-step explanation:
In 2001 the total number of marketed units= 730,000
If this number represents 50% of what was marketed in 2004, then the total number of units marketed in 2004 was:
(100/50)× 730,000=1460000
To get the number for each of the 365 days in 2004 we divide the total for 2004 by 365
1460000/365= 4000 units
Answer: the length of the ladder is 40 meters.
Step-by-step explanation:
The ladder forms a right angle triangle with the wall and the ground.
The length of the ladder represents the hypotenuse of the right angle triangle.
The distance of the base of the ladder due west of the burning building represents the adjacent side of the right angle triangle.
To determine the length of the ladder, h, we would apply the cosine trigonometric ratio. It is expressed as
Cos θ = adjacent side/hypotenuse. Therefore,
Cos 51 = 25/h
h = 25/Cos 51 = 25/0.6293
h = 40 meters to the nearest meter.
