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
:D i hav th same question cuz i hav lik 3 E's
probably one failing grade each quarter or marking period w.e ur school calls it
ik in my school i cn get honor role even tho i hav one C soooo ^thts wat im thinkin
She will make 10 out of the 15 free throws.
Work:
8/12 = x/15
- Cross-multiply
12 • x = 12x
8 • 15 = 120
- Divide
12x ÷ 12 = x
120 ÷ 12 = 10
I am assuming that the whole 3x - 6 in the fraction is the numerator
the this simplifies to 3x (3x - 6)
= 9x^2 - 18x (C)
Answer:
22 hours (B)
Step-by-step explanation:
John's velocity = 55mph
Sally's velocity = 65mph
John's time taken = x
Sally's time taken = x - 4
since they must cover the same distance.
and, distance = vel × time
Sally's vel × time = John's vel × time
55x = 65(x-4)
55x = 65x - 220
-10x = -220
x = 22 hours.
Therefore, Sally catches up after 22 hours
