 Divide 1 hour in the ratio 1 : 9 : 10
olganol [36]

Answer:

3 minutes; 27 minutes; 30 minutes

Step-by-step explanation:

Let the common multiplier of the given ratios be x. So, the ratios 1: 9 : 10 will become x, 9x and 10x respectively.

Therefore,

x + 9x + 10x = 1 \: hour \\  \\ 20x = 60 \: minutes \\  \\ x =  \frac{60 \: minutes}{3}   \\  \\ x = 3 \: minutes \\  \\ 9x = 9 \times 3 = 27 \: minutes \\  \\ 10x =  10 \times 3 = 30 \: minutes

Thus, 1 hour in the ratio 1 : 9 : 10 can be divided as:

3 minutes; 27 minutes; 30 minutes

If you launch the cannonball from the ground instead (hi=0), what does that change in the original equation?
ikadub [295]

Answer:

  the value of hi changes from 58 to 0:

  h(t) = -4.9t^2 +19.8t

Step-by-step explanation:

If the initial height changes, then the term in the equation that represents that height will change. The initial height term is hi, so it changes from 58 to 0.

  h(t)=-4.9t^2+19.8t+0\\\\\boxed{h(t)=-4.9t^2+19.8t}
