Answer:
3485 ft
Step-by-step explanation:
The height above the radar station is found using ...
height = distance × sin(angle)
height = (4200 ft) × sin(55°) ≈ 3440 ft
Since the radar station is 45 ft above the ground, the height of the clouds will be an additional 45 ft:
3440 ft + 45 ft = 3485 ft . . . . height of clouds

<em>Comment on units</em>
You need to be a bit careful here because one dimension is given in feet and another in yards. You need to use 1 yard = 3 feet to figure that 1400 yards = 4200 feet. You could convert 45 ft to 15 yards and report the cloud height in yards. That would not be wrong, but it would be unusual.
Step-by-step explanation:
a polynomial has two or more terms and cannot have a variable in the denominator. so the answer is B and C
Total circle = 360°
1/2 of circle = 1/2 x 360 = 180°
1/4 of the circle = 1/4 x 360 = 90°
Similarly,
1/8 of the circle = 1/8 x 360 = 45°
You would need about 8 cups more. If you make 2 2/3 a improper fraction and then multiply it by three, you would get 24/3, which is eight in simplest form.
Answer:
D 11/12
Step-by-step explanation:
the fractions round up by 2
example, 2/12, 4/12, 6/12, 8/12.... etc
