18 groups of 7 is 18*7 = 126
20 groups of 6 is 20*6 = 120
so 18 groups of 7 is greater.

### Can you use 18 volt charger for 20 volt battery

No. It will not charge
to get batteries to charge the voltage in has to be greater than the battery voltage so the charger you want is 20 volts which in fact will probably be charging at 22 volts

### What are the shafts?

Most shafts are generallymade from plastics or metals such as aluminum and titanium. They can be rigidor flexible. I prefer a longer shafts arrow which provide greater stability andallow a reduction in flight which can eventually lead to closer grouping.

### I have a husqvarna 350 that wont start, wondering if anyone can tell me what is the factory compression rating?

Hi and welcome to FixYa, I am Kelly You should have 120 PSI or greater compression. There is a ported compression release so you may see as little as 110 PSI but it is best to see 120 or greater.

### I'm plan on buying a 70-200 2.8 len do i really

They're most definitely not the same lens, even discounting the Image Stabilization feature. The L has 18 elements in 15 groups. The IS has 23 elements in 18 groups. There's also an IS II, which has 23 elements in 19 groups.

Look at http://www.usa.canon.com/consumer/controller?act=ProductCatIndexAct&fcategoryid=150 and you can compare them yourself.

### The sum of the digits of a two-digit number is 14. if the digit is reversed, the number is increased by 18. what is the number?

a 2 digit number is a tens place digit plus a singles place digit:
10x + y

if you reverse the 2 digits, it looks like:
10y + x

So, the original 2-digit number, plus another 18, gets the 2nd 2-digit number:

10x + y + 18 = 10y + x

AND adding the 2 digits gets 14:
x+y = 14

Solve for x: x = 14-y

Substitute x back into the previous equation and solve for y:

10 (14 - y) + y + 18 = 10y + (14 - y)

140 - 10y + y + 18 = 10y + 14 -y

158 - 9y = 9y + 14

144 - 9y = 9y

144 = 18y

y = 8

So if y = 8, x must equal 6: x+ y = 14 --> 6 + 8 = 14

And the original number, 68, if you reverse the digits --> 86

86 is 18 greater than 68.

I love math!
