maks197457 [2]

Answer:

1/3

Step-by-step explanation:

I think this is 1/3 because it is a ratio of successful outcomes to total number of outcomes..

Ex. Rolling a 6 sided dice.. you roll a 5...  it would be 1/6.

Hope that makes sense.

The function h(t) = 210 – 15t models the altitude of a hot air balloon over time t, in minutes.
Marysya12 [62]
<span>h(t) = 210 – 15t models the altitude of a hot air balloon over time t, in minutes

means that at time t min, the height h of the balloon is 210-15t    (units)

for example,

at time t=1 min, the height of the balloon is 210-15*1=195 (units)

at time t=2 min, the height of the balloon is 210-15*2=210-30=180  (units)


Thus, h(10) is the height of the balloon at time t=10 min,

h(10)=210-15*10=210-150=60</span>
