Answer:
The rock splashes down when h(t) = 0. Set h(t) = 0 and solve for t using quadratic formula.
0 = − 4.9t^2 + 178t + 325
t = 38.07, -1.74
(Throw away the negative answer, since time can't be negative.)
t = 38.07 sec

You would cross multiply.
14 over 31.5
and X over 10.5
10.5 times 14 is 147
divide that by 31.5 which is 4 1/3
and that is how fast she can run
4 1/3 mph
Answer:
120 millimeters or 0.12 liters
Step-by-step explanation:
To solve this question :
- we have to convert liters to millimeters
- multiply the serving of coca by the number of people that consumed the coca
- subtract the answer gotten from the step above from 2 litters
1 liter = 1000 millimeter
2 liters = 2 x 1000 = 2000mm
8 people drank cocoa = 8 x 235 = 1880mm
Amount of cocoa left over = 2000 - 1880 = 120mm or 0.12 liters
