Answer:
The height of the incline is 462 feet
Step-by-step explanation:
Here, we are asked to calculate height, given the angle of elevation.
When we talk about angle of elevation, we refer to the observation angle that we have when we look up from a position which is at the base.
Please check attachment for diagrammatic representation of the question terms.
From the attachment, we can see that we have a right angled triangle. We are asked to calculate the opposite given the adjacent.
Thus the trigonometric identity to use is the Tangent
Tan 30 = h/800
h = 800 * Tan 30 = 461.88 approximately 462 feet
Answer:
There's 21% of chances
Step-by-step explanation:
Here we have to use the definition of a simple probability, where all fishes has the same probability to be chose.
So, we have to divide the possible outcomes with the total of outcomes. The possible outcomes refer to the number of large-blue fishes, and the total number of outcomes represent the total number of fishes. So
P = 3/4 ≈ 0.21 (or 21%)
Therfore, there's 21% of chances to select one fish randomly and be a large, blue fish.
Answer:
1,231 people
Step-by-step explanation:
1,256 people currently subscribe. $0.25 is 5 nickels, and for every nickel the price is raised, 5 people unsubscribe. That's 1 person per cent. 25 people will unsubscribe for every $0.25 the price is raised. 1,256-25 is 1,231, so 1,231 people will continue to subscribe after the price increase.
The answer is x is less than equal to -5.
