Question 1210639: Came across this log table:
log 1.1 = 0.04139 393 783 1169 1551 1931 2307 2680 3049 3416
I compared these numbers with another log table and the numbers differ. Would someone give an explanation for the difference ? Thanks.
Note: Each 3 and 4 digit numbers are separated, not one large number.

Question 1210626: Another logarithm question:
Calculate log 5601 using table.
Not in table.
Closest: 5599 = 363 5611 = 364 Difference of .001
Difference of 5601 - 5999 = 2
Difference of 5611 - 5601 = 10

Question 1164633: The U.S. currently has seven federal income tax brackets, with rates of 10%, 12%, 22%, 24%, 32%, 35% and 37%. If you fall into the 37% bracket, that doesn’t mean that the entirety of your taxable income will be subject to a 37% tax. Instead, 37% is your top marginal tax rate.
FEDERAL TAX BRACKETS 2018 - 2019 Tax rate (%)
$0 - $9,525 10
$9,526 - $38,700 12
$38,701 - $82,500 22
$82,501 - $157,500 24
$157,501 - $200,000 32
$200,001 - $500,000 35
$500,001+ 37
Table : 1 Federal income tax brackets
Required:
i) Create a Mathematical Model that represents the aforementioned information to calculate the annual income tax.
ii) How much annual income tax you will have to pay if your monthly taxable income is $ 40,000?

Question 53086: My daughter got this word problem for school and it sounds pretty simple to me
but I have tried everything and I am horrible at math so I need a little help
before I throw my calculator out the window! Here is it
Linae went shopping for Kou-jong tiles at the local toy shop the other day. The kou-jong tiles were on sale for only 28 cents each.
However, she got it in her head that, for good luck, the total amount of money she must spend must be a number where all of the digits are the same.
With that in mind, what is the minimum number of tiles she must buy?

Question 1210603: I came across this in an old book:
Determine logarithm of 6253.
In table, the mantissa is .7959 (The same mantissa of 6250). The next larger is .7966, mantissa of 6260.
6260 - 6250 = 10 (difference of 10).
.7966 - .7959 = 0.0007
This is part I don't understand:
Each increase of 1 unit (6250 increase of 10 to 6260), mantissas of their logs increase by 0.0007, an increase of .1 of 0.0007. 3 added to 0250 will add .3 of 0.0007 or 0.0002 to the mantissa of 6253.
Why is .1 and .3 added ?
