Answer:The 45 45 90
Step-by-step explanation:
Theorem states that 45 45 90 special right traingles that have sides of which the lengths are in a special ratio of 1 : 1 : 2 1:1:/sqrt{2} 1:1:2 and two 4 5 45 45 angles and one right angle of 9 0 90 90.
The answer is given above
Answer:
<u>$15 per hour</u>
Step-by-step explanation:
Since he charged $65 for the parts, and the total charge was $110, that's $110-$65 which is $45, the total hours was 3, so $45 divided by 3, and that equals $15.
Step-by-step explanation:
Using similar triangles, the height and width of the water is proportional to the height and width of the trough.
w / h = 5 / 1
w = 5h
The volume of the water is:
V = AL
V = (½ wh) (14)
V = 7wh
Substituting:
V = 7(5h)h
V = 35h²
Take derivative with respect to time:
dV/dt = 70h dh/dt
Given that dV/dt = 15 and h = ⅓:
15 = 70 (⅓) dh/dt
dh/dt = 9/14
dh/dt ≈ 0.643 ft/min
