Question 985152: Hello Sir,
I want to know "Octal to Decimal conversion" formula
&
Hexadecimal to Decimal conversion formula.
Please help me in this.
Thanks
Answer by Edwin McCravy(13211) (Show Source):
You can put this solution on YOUR website! I'm assuming you mean converting whole numbers, integers.
Converting fractions is different.
For octal, the algorithm is this, starting with the first digit
Multiply by 8
Add next digit
Multiply by 8
Add next digit
.....
In hex, just use 16 instead of 8, and remember that A=10, B=11, etc.
until you run out of digits.
Suppose you have the octal number
64721053_{8}
Start with first digit 6
6
6*8+4 = 52
52*8+7 = 423
423*8+2 = 3386
3386*8+1 = 27089
27089*8+0 = 216712
216712*8+5 = 1733701
1733701*8+3 = 13869611
64721053_{8} = 13869611_{10}
Suppose we have the hex number:
D59A52C_{16}
You might want to write it this way first:
(13)59(10)52(12)
Start with D which is 13
13
13*16+5 = 213
213*16+9 = 3417
3417*16+10 = 54682
54682*16+5 = 874917
874917*16+2 = 13998674
13998674*16+12 = 223978796
So D59A52C_{16} = 223978796_{10}
It's very easy with a TI graphing calculator, because when
you press *16+ after a calculation you don't have to reenter
the last number, it just automatically uses it as Ans and you
see Ans*16+. So it's very fast on a TI.

Answer by Alan3354(47455) (Show Source):
You can put this solution on YOUR website! Please help me to solve these questions.,
A). Determine the decimal equivalent of the given number(67.33)8.
If you mean base 8,
> 6*8 + 7 + 3/8 + 3/64
= 55.421875
=============
B). Determine the decimal equivalent of the given number(115)16
= 256 + 16 + 5
= 277
Question 981219: What is the smallest number that rounds to 250 to the nearest ten?
What is the largest number that rounds to 250 to the nearest ten?
How many numbers round to 250 to the nearest ten?
Answer by KMST(3791) (Show Source):
You can put this solution on YOUR website! When the digit that is going to be discarded is 5 or more,
the digit to its left is increased by 1.
Otherwise the digit to the left is unchanged
According to the rules above,
245 rounds to 250 to the nearest ten, and 244 rounds to 240,
because the digit that is going to be discarded is the 5 or 4 at the units place,
and when the digit to be discarded is 5 or more,
the digit to its left (in this case the 4 in the tens place) is increased by 1,
but otherwise the digit to the left is unchanged
So is the smallest number that rounds to 250 to the nearest ten.
Similarly, according to the rules above,
254 rounds to 250 to the nearest ten, and 255 rounds to 260.
So is the largest number that rounds to 250 to the nearest ten.
Numbers greater than do not round to 250 to the nearest ten.
Numbers smaller than do not round to 250 to the nearest ten.
Out of the numbers from 1 to 254,
the first (1 to 244) do not round to 250 to the nearest ten.
So, the number of numbers that round to 250 to the nearest ten is
.

2.find 3% of 200 pesos
3.a municipality levies a 12% sales tax. Find the tax on a car listed 350,000 pesos
Answer by Boreal(1464) (Show Source):
You can put this solution on YOUR website! 91/16=5 and 11/16
11/16=0.6875
5.69
200*0.03=6 3% of 100 is 3, and 3% of 200 is 6.
350,000*0.12=42,000
Ten per cent would be 35,000
one per cent is 3500
two per cent is 7000
Twelve per cent is 42000

Answer by Edwin McCravy(13211) (Show Source):
Question 972856: 4. Hydrologists sometimes use Manning's equation to calculate the velocity v, in feet per second, of water flowing through a pipe. The velocity depends on the hydraulic radius Rin feet, which is onequarter of the diameter of the pipe when the pipe is flowing full; the slope S of the pipe, which gives the vertical drop in feet for each horizontal foot; and the roughness coefficient n, which depends on the material of which the pipe is made. The relationship is given by the following.
v =
1.486
n
R2/3S1/2
For a certain brass pipe, the roughness coefficient has been measured to be n = 0.014. The pipe has a diameter of 3 feet and a slope of 0.4 foot per foot. (That is, the pipe drops 0.4 foot for each horizontal foot.) If the pipe is flowing full, find the hydraulic radius of the pipe. (Round your answer to two decimal places.)
ft
Find the velocity of the water flowing through the pipe. (Round your answer to two decimal places.)

'
10^0 = 1, 20^0 = 1, 30^0 = 1, 7^0 = 1, 9^0 = 1, (7)0 = 1
`
Every number raised to the zero power is 1 with one exception.
`
That one exception is that 0^0 is not defined".
`
10 is not 0, so therefore 10^0 = 1
