Answer:
Benny would have 1/3y CDs.
Step-by-step explanation:
In order to find this, we know that Richard has 3 times the amount of CDs Benny does. Therefore, conversely, we must know that Benny has 1/3 of the CDs that Richard does. Knowing that Richard has y CDs allows us to model the amount for Benny as 1/3y.

Answer: 17
Step-by-step explanation:
What do you need?
2log 3/8
= -0.85
Step 1: I drew a visual representation
Step 2: write the formulae for the volume of a sphere which is V=4*PI*r cubed all divided by 3. Refer to my image
Step 3: answer is 7234.56 cm cubed
First, we need to think about what we're actually solving for: the area of the path. To find this, we can find the area of the whole thing, minus the area of the pool.
The diagram would look something like the picture I attached. We know that to find the area of a circle, you do πr^2. The radius is half of the diameter, so halve the diameters:
22/2 = 11 yards
32/2 = 16 yards
Then solve for the area of both circles.
π


π ≈ <span>380.13 (area of the pool)</span>
π


π ≈ <span>804.25 (area of the whole thing)
</span>
Next, subtract the area of the pool from the area of the whole thing to find the area of the walkway:

(area of the walkway)
Finally, divide the area of the walkway by 6 to see how many gallons of paint you'll need:
424.12 ÷ 6 ≈ 70.69
So you'll need 71 gallons of paint!
