Step-by-step explanation:
Given that 9 cups of macaroni requires 27 cups of water
Therefore, 1 cup of macaroni will require 27/9 = 3 cups of water
Now i can help you to work out the correct way of filling the table;
If 1 cup of macaroni requires 3 cups of water
x cups of macaroni will require 9 cups of water
x = 9 *1/3
x = 3 cups of macaroni
If 1 cup of macaroni requires 3 cups of water
x cups of macaroni will require 33cups of water
x = 33 *1/3
x = 11 cups of macaroni
If 1 cup of macaroni requires 3 cups of water
x cups of macaroni will require 21 cups of water
x = 21 *1/3
x = 7 cups of macaroni
If 1 cup of macaroni requires 3 cups of water
x cups of macaroni will require 27 cups of water
x = 27 *1/3
x = 9 cups of macaroni
Use this to tick the table.
Answer:
9.6 seconds
Step-by-step explanation:
The equation for projectile motion in feet is 
where 
is the initial velocity in ft/s and 
is the initial height in feet.
We are given that the initial upward velocity is 
and the initial height is 
. Thus, plugging these values into our equation, we get 
as our equation for the situation.
The firework will land, assuming it doesn't explode, when 
, thus:
Since time can't be negative, then the firework will land after 9.6 seconds, assuming it doesn't explode at the time of landing.
