In 20X1, Ginzel Corporation agreed to provide a client with 20 detailed marketing analyses of its client's key products for a total fee of $110,000. The fee was computed as $5,000 per report × 20 reports = $100,000, plus $10,000 to extract the necessary data from the client's system and convert it into the format Ginzel needs to do the analysis. It cost Ginzel $4,000 to complete the data extraction and conversion. As of December 31, 20X1, Ginzel has completed the conversion of the data and has completed and delivered 7 of the 20 marketing reports to the client. 1. How much revenue should Ginzel recognize in 20X1? 2. How should Ginzel account for the $4,000 in costs it incurred to extract and convert the client's data?
Answers
Answer:
$38,500$1,400Step-by-step explanation:
1. According to the Accrual Principle of Accounting, revenue should only recognized when the goods or services for which it was paid for have been delivered. In other words, revenue should only be recognized when earned.
As of December 1, 20X1, Ginzel had only completed 7 of the 20 reports so the revenue recognized should be for the completed reports alone.
Total revenue for 20 reports = $110,000
Revenue for 7 reports = 7/ 20 * 110,000
= $38,500
2. The Accrual principle also applies to expenses and states that expenses should only be accounted for when incurred. As the $4,000 relates to all the reports, it should be apportioned evenly.
The costs of extraction and conversion of data for the year should therefore be;
= 7/20 * 4,000
= $1,400

What is the vertex of y=3|x+1|-2
Answers
Answer:
(-1,-2)
Step-by-step explanation:
Generally, the absolute value function can be expressed like so:
f(x) = y = a|x-h|+k, where vertex: (h,k)
Rewriting our function here ever so slightly gives us: y = 3|x-(-1)|+(-2)
So the vertex is at (-1,-2)

You need to put your reindeer, Ezekiel, Lancer, Rudy, and Jebediah, in a single-file line to pull your sleigh. However, Jebediah and Rudy are best friends, so you have to put them next to each other, or they won't fly.
Answers
Answer:
Well to start out you have 5 reindeer. If you glue Lancer and Ezekiel together you only have 4 units to arrange in different orders. That number is 24. But for each of those, Lancer and Ezekiel can be arranged in two ways... with Lancer in front of the pair or in the back of the pair. So altogether there are 48 ways to arrange the five reindeer with Lancer and Ezekiel always being together.
Answer:
Put Jebediah and Rudy in the back of the line next to each other, and the 2 others single file in front

If two alternate angles are formed on parallel lines, they are said to be______
a. complementary
b. equal
c. supplementary
d. transversal
Answers
Answer:
b
Step-by-step explanation:
equal. where are you from?
If two alternate angles are formed on parallel lines, they are said to be b) equal.
Parallel lines are lines that never intersect, they are at equal distance from each other forever. If passed a transversal between the two parallel line, the angles forming have many relations like corresponding angles, alternate angles, co - interior angles or co - exterior angles.
Given in the question, we have alternate angles, maybe interior of the parallel lines or maybe exterior of the parallel line, but always on the opposite side of transversal. But, alternate angles are always equal to each other.
Thus option b is correct.
