Just need to set up an equation.
List what we know Randi made twice what sister did.

So 2X = Randi balloons made
X= Sister balloons made
We also know they made 0.5 for each animal so sales made / price = number sold
2X + X = 48/0.5
3X = 96
X = 32
So Randi made 64 And her sister made 32.
Cause 2X = Randi and X = sister

Answer:

The time it took for the bottle rocket to reach a height of 200 feet is 60 seconds.

Step-by-step explanation:

The function for the height of the bottle rocket (in feet), <em>t</em> seconds after  it is launched is:

h(t)=1157-16\ t

Compute the value of <em>t</em> as follows:

h(t)=1157-16\ t

200=1157-16t

 16t=1157-200\\16t=957\\

     t=59.8125\\t\approx60

Thus, the time it took for the bottle rocket to reach a height of 200 feet is 60 seconds.

Gelneren [198K]

Answer:

50 times

Step-by-step explanation:

You are going to flip a coin 100 times. There are 2 sides. So, what you would do is divide 100 by two because there are two sides. There is a 50% chance that the coin will land on heads, and a 50% chance it will land on tails.

Please let me know if you have any more questions. Hope this helps!
