Answer:
Step-by-step explanation:
Tax payable:
= $4,543+($41,000-$39,476)×22%
= $4,543+$335.28
= $4,878.28
Tax rate:
= $4,878.28/$41,000
= 11.9%
<em>Hence, Tax rate is 11.9%</em>
Answer: the answer is on a calculator
Step-by-step explanation:
If your aboe to do that you can so anything
Do you remember when you were learning about
Least Common Multiple (LCM) ? And you were
wondering what on Earth you would ever need it for ?
THIS IS IT !
The amount of time after 8 PM when the lights will flash
together again is the LCM of 20 seconds and 30 seconds.
Do you remember how to find it ?
... When 20 is prime-factored, you have 2 · 2 · 5 .
... When 30 is prime-factored, you have 2 · 3 · 5 .
... So the Least Common Multiple of 20 and 30 is 2 · 2 · 3 · 5 = 60 .
The lighthouses will flash together again in 60 seconds after 8 PM.
That'll be 8:01 PM.
Answer:
x = 1
Explanation:

Rule: log(a) + log(b) = log(ab)

cancel out log on both sides

relocate constant variable

take 3 as a common factor

divide both sides by 3

middle term split

factor common terms

collect into groups

set to zero

relocate variables

There must be a positive solution for log, so the solution is only x = 1
15 * 25 = 375 <=== simple multiplication
