Answer:
50 seconds
Step-by-step explanation:
Well, if the bird is travelling 8 m/s then you divide 400 by 8 to figure out how long it would take it to fly, since 8 x 50= 400.
We determine first the real dimension of the circular fountain by using the scale factor given.
(18 cm) x (4 ft / 3 cm) = 24 ft
Then, calculate for the area of the base of the circular fountain by the equation,
A = πD²/4
where A is are and D is diameter. Substituting,
A = π(24 ft)²/4 = 144π ft² ≈ 452.4 ft²
Thus, the area of the base of the circular fountain is approximately 452.4 ft².
Answer:
r ≥ -49/11
Simplified versions: r ≥ -4.45 or r ≥ -4 5/11
So set up as a proportion. 2/25 = x/700
Cross multiply and solve for x.
25x =1400
X = 56
