Answer:
im not too sure but my best guess would be
D= 900×T
D= the constant of proportionality multiplied by time to get how many miles traveled.
if the hours given were 1 hour 2 hours & 3 hours
if you multiplied them by 900 you would get the distanced traveled
900 x 1 = 900 miles traveled in one hour
900 ×2 = 1800 miles traveled in 2 hours
sounds good ?
Answer:
Step-by-step explanation:
he sold 36 so lets subtract that from the 200 so he has to sell 164 more.
Now we have to figure out what times 24 is 164

Answer:
3.15 seconds is the answer.
<u>Explanation</u>
when the ball touches the ground, h =0
hence,
0=255-21t-16t²
16t²+21t-225=0
here a=16 ,b=21, c= -225
time cannot be negative, hence t = -4.46 can be avoided
The ball takes 3.15 seconds to hit the ground.
