In the 01 July 2016, Samsung Ltd acquired the machine A by $1,502,000. Estimated useful life is 10 years, estimated residual value is $2,000. Company uses straight-line method for depreciation. From 2019, Samsung Ltd measure the machine A by the revaluation model. At 30 June 2019, machine A was revalued to $ 1,400,000. After one year, at 30 June 2020, machine A was revalued to $1,000,000. At 30 June 2021, machine A was revalued to $1,500,000. Required: Prepare the journal entries from 01 July 2016 to 30 June 2021. (using both method for revaluation)
Answers
a) Samsung Ltd will record these Journal Entries from July 2016 to June 30, 2021, using the straight-line and revaluation methods of depreciation:
July 1, 2016 Debit Equipment $1,502,000
Credit Cash $1,502,000
To record the purchase of the machine A.June 30, 2017 Debit Depreciation Expense $150,000
Credit Accumulated Depreciation $150,000
To record the depreciation expense for the first year.June 30, 2018 Debit Depreciation Expense $150,000
Credit Accumulated Depreciation $150,000
To record the depreciation expense for the second year.June 30, 2019 Debit Accumulated Depreciation $300,000
Credit Revaluation Reserve $300,000
To close the accumulated depreciation to Revaluation Reserve.June 30, 2019 Debit Revaluation Reserve $198,000
Credit Revaluation Surplus $198,000
To record the Revaluation Surplus.June 30, 2020 Debit Revaluation Expense $400,000
Credit Revaluation Reserve $400,000
To record the revaluation loss.June 30, 2021 Debit Revaluation Reserve $500,000
Credit Revaluation Surplus $500,000
To record the revaluation surplus.Data and Calculations:
Cost of machine on July 1, 2016 = $1,502,000
Estimated Residual Value = $2,000
Depreciable amount = $1,500,000
Estimated useful life = 10 years
Based on the straight-line method the depreciation expense for each year = $150,000 ($1,500,000/10).
Value of Machine at:
June 30, 2019 - $1,400,000
June 30, 2020 = $1,000,000
June 30, 2021 = $1,500,000

The world population of a certain species is evaluated at 6.8 × 109. By some projections, this population will be 8 times more important in 30 years. Express the population at that time in scientific notation.
Answers
Using the multiplication operation, the population of the species in 30 years would be 8 times the current population. Hence, the population at the time would be [tex] 5.44 \times 10^{10}[/tex]
Current population = [tex] 6.8 \times 10^{9}[/tex]Therefore, 8 times the current population can be calculated thus :
[tex] 6.8 \times 10^{9} \times (8) = 54.4 \times 10^{9}[/tex]
Therefore, the population at the time would be [tex] 5.44 \times 10^{10}[/tex]

Step-by-step explanation:
the 165 degree obtuse angle forms a straight line with the upper left angle inside the triangle, therefore this angle measures 15 degrees
we know two of the three angle measures so we add all three together to find the unknown angle
x + 15 + 45 = 180

Q4). If the ordered pairs (x+1,5) and (4,x+2y) are equal then find x and y.
Answers
Step-by-step explanation:
Given that (x+1,5) = (4,x+2y)
⇛ x+1 = 4 and 5 = x+2y
⇛ x = 4-1
⇛ x = 3
now
5 = x+2y
⇛ 5 = 3+2y
⇛ 5-3 = 2y
⇛ 2 = 2y
⇛ 2y = 2
⇛ y = 2/2
⇛ y = 1
Therefore, x = 2 and y = 1

How many palindromes between 1000 and 9999 inclusive are divisible by 9?
Answers
Palindromes are numbers that remain the same, when reversed.
There are 10 palindromes divisible by 9 between 1000 and 9999
To do this, we list the numbers divisible by 9 between 10 and 99.
The numbers are:
[tex]\mathbf{A = 09,\ 18,\ 27,\ 36,\ 45.\ 54,\ 63,\ 72,\ 81,\ 90,\ 99}[/tex]
Flip these numbers
[tex]\mathbf{B =90,\ 81,\ 72,\ 63,\ 54.\ 45,\ 36,\ 27,\ 18,\ 09,\ 99}[/tex]
Combine corresponding numbers
[tex]\mathbf{AB =0990,\ 1881,\ 2772,\ 3663,\ 4554,\5445,\ 6336,\ 7227,\ 8118,\ 9009,\ 9999}[/tex]
Rewrite as:
[tex]\mathbf{AB =990,\ 1881,\ 2772,\ 3663,\ 4554,\5445,\ 6336,\ 7227,\ 8118,\ 9009,\ 9999}[/tex]
990 is less than 1000.
So, we have:
[tex]\mathbf{AB =1881,\ 2772,\ 3663,\ 4554,\5445,\ 6336,\ 7227,\ 8118,\ 9009,\ 9999}[/tex]
Count the numbers
[tex]\mathbf{n(AB) =10}[/tex]
Hence, there are 10 palindromes divisible by 9 between 1000 and 9999
