Answer:

data manipulation language

Explanation:

Data manipulation language (DML) is a family of similar syntactic elements used to select, insert, delete and update data in a database. Performing data read-only queries is sometimes considered a component of the DML.

The best known data manipulation language is the SQL (Structured Query Language) that is used to receive and manipulate data in a relational database. Other forms of DML are those used by IMS / DLI, CODASYL databases, such as IDMS and others.

Data manipulation languages ​​comprise only the SQL statements that allow you to modify data, but not modify the schema or objects of the database. The manipulation using SQL statements of persistent database objects such as tables or stored procedures, is considered Data definition language and not Data manipulation language. In SQL these two categories are similar in their syntax, data types, expressions, etc., but they are different in their general function.

Musya8 [376]

Answer:

The option (B) Debit Work in Process Inventory $72.000 credit Factory Wages Payable $172,000 is correct

Explanation:

Solution

Given that:

As the cost of labor was sustained as regards to processing the inventory and it was not completed, so debit the work in process of account.

There also exits a liability of paying labor charges for this it will be payable.

Hence credit factory wages payable.

For the other options they are crediting cash which is not yet paid, here the option A  and E is wrong.

For option D, they are crediting inventory which in this case is not correct due to the existence of a liability for paying labor fees.

The option D is wrong, because they debited with the cost of sold goods.

Your​ company, which has a MARR of​ 12%, is considering the following two investment​ alternatives:
mote1985 [20]

Answer:

future worth:

project A  11,615.26

project B  12,139.18‬

It should choose project B as their future value is greater

IRR of project A: 13.54%

We should remember that the IRR is the rate at which the net value is zero thus, equals the inflow with the cash outlay

It is calculate with excel or financial calculator due to the complex of the formula.

Explanation:

Project A

We calculate the future value of the cash flow per year and cost as we are asked for future value. The salvage value is already at the end of the project life so we don't adjust it.

Revenues future value

C \times \frac{(1+r)^{time} -1}{rate} = FV\\  

C 15,000

time 8

rate 0.12

15000 \times \frac{(1+0.12)^{8} -1}{0.12} = FV\\  

FV $184,495.3970  

Expenses future value

C \times \frac{(1+r)^{time} -1}{rate} = FV\\

C 3,000

time 10

rate 0.12

3000 \times \frac{(1+0.12)^{10} -1}{0.12} = FV\\  

FV $52,646.2052  

Cost future value

Principal \: (1+ r)^{time} = Amount  

Principal 40,000.00

time 10.00

rate 0.12000

40000 \: (1+ 0.12)^{10} = Amount  

Amount 124,233.93

Net future worth:

-124,233.93 cost - 52,646.21 expenses + 184,495.40 revenues + 4,000 salvage value

future worth 11,615.26

Project B

cost:

Principal \: (1+ r)^{time} = Amount  

Principal 60,000.00

time 10.00

rate 0.12000

60000 \: (1+ 0.12)^{10} = Amount  

Amount 186,350.89

expenses 52,646.21 (same as previous)

revenues

C \times \frac{(1+r)^{time} }{rate} = FV\\  

C 24,000

time 7

rate 0.12

24000 \times \frac{(1+0.12)^{7} -1}{0.12} = FV\\  

FV $242,136.2815  

TOTAL

242,136.28 + 9,000 - 52,646.21 - 186,350.89 = 12,139.18‬

Internal rate of return of project A

we write the time and cash flow for each period.

Time Cash flow

0 -40,000

1 -3,000

2 -3,000

3 12,000

4 12,000

5 12,000

6 12,000

7 12,000

8 12,000

9 12,000

10 16,000

IRR 13.54%

Then we write on excel the function =IRR(select the cashflow)

and we got the IRR of the project
