Answer:
1/4 of the full container remains
Step-by-step explanation:
Step 1: Half the milk is poured out
i.e 1/2 of the milk remains
Step 2: 1/3 of what remains is poured out --> 2/3 of the remaining is not poured out.
Hence amount remaining after step 2 = 2/3 x 1/2 = 1/3 of the total
Step 3: 1/4 of what remains is poured out --> 3/4 of the remaining is not poured out.
Hence amount remaining after step 3 = 3/4 x 1/3 = 1/4 of the full container remains
Preston has 19 games and Horatio has 30 games.
You can set this as a system of equations, set Preston as x and Horatio as y.
Both of the amounts add up to 49, so we can get the equation:
x+y=49
Since Horatio has 11 more games, we can get the equation:
y-x=11
If we add the x to the other side, the second equation becomes:
y=x+11
We can plug in the second equation into the first and get the equation:
x+11+x=49
with a little simplification, we get x (Preston) is equal to 19. If we add 11 to it, we get Horatio's amount: 30
Answer: 1st, 3rd, and 4th functions
Step-by-step explanation:
Assuming k(x)=9x^2, all the other functions have inverses because they are linear, meaning they must be one-to-one.

Answer:
x=8cm
Step-by-step explanation:
32=4x
divide both sides by four to get 8=x
32/4=8
4x/4=x
8=x
