Answer:
200 ft 200
t = -------------------- = ---------- min
(S + T) ft/min S + T
Step-by-step explanation:
Recall that distance = (rate)(time).
The distance traveled by the turtle in t minutes is dt = (T ft/min)(t), and
the distance traveled by the snail in t minutes is ds = (S ft/min)(t). We know that ds + dt must be 200 ft.
Thus,
(S ft/min)(t) + (T ft/min)(t) = 200 ft.
The variable t, representing elapsed time, is common to both terms on the left. Thus,
200 ft 200
t = -------------------- = ---------- min
(S + T) ft/min S + T
Answer:
Step-by-step explanation:
circumference = 
* diameter
circ = 3 * 32
circ = 96
5:3
x:12
x=20
The height of the tree should be 20 feet
Answer:
15.6
Step-by-step explanation:
the traingle is right so u have to apply the pythagorean theorem to find x so x^2=10^2+12^2=244
so x=15.6
27 because 6*9 is 54,54 divided by 2 is 26
