Answer:
C.There are 6.8 kiloliters in 68 hectoliters.
Step-by-step explanation:
1 hectolitre = 100 litres
1 decilitre = 0.1 litre
1 kilolitre = 1000 litree
6.8 kilolitres = 6800 litres
Or 68 hectolitres
i think this is a systems of equations
putting this on a graph we have to equations:
y = 10x + 30
y = 20x
graph and find the intersection.
it has to be more than or equal to 3 miles i think for wreckomend
Answer:
See below
Step-by-step explanation:
Vertical velocity will be affected by gravity in this scenario
df = do + vo t + 1/2 a t^2 do = original height = 4 ft a = -32.2 ft/s^2
<u>df = 4 + 89 t - 1/2 (32.2) t^2 df = height</u>
<u />
On the way up and the way down, the ball may reach height of 102.2125 ft :
102.2125 = 4 + 89 t - 1/2 (32.2) t2 re-arrange to:
-16.1 t^2 + 89t - 98.2125 =0
Use Quadratic Formula to find <u>t = 1.5 and 4.0 s </u>
