Correct Question: Find the simplified product: \sqrt{2x^3}*\sqrt{18x^5}

Answer:

6x^4

Step-by-step explanation:

Based on the rules of radicals, since \sqrt{2x^3} and \sqrt{18x^5} has the same index (square root), therefore:

\sqrt{2x^3}*\sqrt{18x^5} = \sqrt{2x^3 * 18x^5}

To simplify this, multiply their bases together, and add their exponents.

= \sqrt{2*18x^{3+5}

= \sqrt{36x^{8}

Simplify further

= \sqrt{36}*\sqrt{x^8}

= \sqrt{6*6}*\sqrt{x^4*x^4}

= 6x^4

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

Addy’s monthly water bills for last year are $27, $31, $30, $26, $25, $27, $37, $33, $32, $28, $26, $26. Express the formula for
Sav [38]

Answer:

Σ( xi ) / n ; $29

Step-by-step explanation:

Given the following data:

X= $27, $31, $30, $26, $25, $27, $37, $33, $32, $28, $26, $26

Number of observations (n) = 12

Mean formula (m) = ( Σ xi ) / n

Where i = each individual value in X

Mean water bill for the years is thus :

m = Σ [(27 + 31 + 30 + 26 + 25 + 27 + 37 + 33 + 32 + 28 + 26 + 26)] / 12

m = 348 / 12

m = 29

Hence, the mean water bill for the year is $29

48 people attended the Sunday matinee to watch a film. .Three over 8 of the people went to see a romantic comedy. .One over six
never [62]

Answer:

22 people saw an horror movie

Step-by-step explanation:

Total people who attended the Sunday matinee = 48

People who saw romantic comedy = 3/8 of 48

= 3/8 × 48

= (3*48) / 8

= 144 / 8

= 18 people

People who saw action movie = 1/6 of 48

= 1/6 × 48

= 48/6

= 8 people

People who saw horror movie = x

Total people who attended the Sunday matinee = People who saw romantic comedy + People who saw action movie + People who saw horror movie

48 = 18 + 8 + x

48 = 26 + x

Subtract 26 from both sides

48 - 26 = 26 - 26 + x

22 = x

x = 22 people

22 people saw an horror movie
