Answer: Choice D
======================================================
Explanation:
The formula for the surface area of a cylinder is
We then replace r with 10 and h with 25. Keep in mind that the diameter is 20 mm, so the radius is half that at 10 mm.
So that's how we get to
<em>The answer is 10:7, 10/7, 10 to 7. Whichever it's asking for. As long as you know the ratio is 10 rock songs to 7 country songs.
</em><em /><u>
</u><em />This problem can be a simple fraction simplification problem. Here's what I mean:
<em>
</em><em />So, we have 40 rock songs and 28 country songs. Let's put that into a fraction:
<em>
</em>
<em>
</em>To simplify this as much as possible, all we have to do is find the greatest common multiple and divide it by both numbers. the GCF is 4, so all you have to do is divide 40 by 4 and 28 by 4 to get your ratios.

8 can go into 12 only once.
Answer:
x=48
Step-by-step explanation:
x-3 15
------------ = ----------
6 2
We can use cross products to solve this problem
(x-3) *2 = 6*15
Distribute
2x-6 = 90
Add 6 to each side
2x-6+6 = 90+6
2x=96
Divide by 2
2x/2 = 96/2
x = 48
7.32 meters. i hope this helps
