Answer:
28 ways
Step-by-step explanation:
After placing 1 ball in each of the seven bins, there are two balls left.
If we place both balls in a single bin, there are 7 different ways to place the balls (place both on bins 1 through 7).
If we place each of the remaining balls in a different bin, the number of ways to place the balls is:

The total number of ways to distribute those balls is 21 + 7 = 28 ways.
All we have to do here is divide 4 by 2
4 ÷ 2 = 2
Therefore, the artist can paint 2 paintings an hour making the unit rate, 2 paintings per hour.
Hope this helps

Answer:

Step-by-step explanation:
Let m be number of minutes it will take to download the whole game.
We are told that computer is downloading at a rate of 0.01 GB per minute and half GB game is already downloaded. So 0.01*m+0.5 will be equal to 2.2 as game size is 2.2 GB.
Let us find the least number of minutes it will take to download the whole game.



Therefore,
is our desired inequality.
Answer:
x=3 meters
Step-by-step explanation:
step 1
Find the area of the rectangular pool

we have

substitute

step 2
Find the area of rectangular pool including the area of the walkway
Let
x ----> the width of the walkway
we have

substitute

step 3
Find the area of the walkway
To find out the area of the walkway subtract the area of the pool from the area of rectangular pool including the area of the walkway
so

step 4
Find the value of x if the area of the walkway equal the area of the pool
so

Solve for x

Solve the quadratic equation by graphing
The solution is x=3 meters
see the attached figure
