Awaste collection tank can hold 18,754 kg of methanol, which has a density of 0.788 g/cm3. what is the volume of the waste collection tank? a. 23,800,000 cm3 b. 23,800 cm3 c. 238 cm3 d. 23.8  cm3

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
