Answer:

Step-by-step explanation:

r10 = 3.555555555...

r100 = 35.55555555...

then, r100-r10 = 35.555... - 3.555...

r90= 32

to find r, divide both sides by90

which will give as ;

r = 32

5/2c-3=3/7c+4 and please explain
Naddika [18.5K]
5/2c - 3 = 3/7c + 4...subtract 3/7c from both sides
5/2c - 3/7c - 3 = 4.....add 3 to both sides
5/2c - 3/7c = 4 + 3....common denominator of 7 and 2 is 14
35/14c - 6/14c = 7...simplify
29/14c = 7....multiply both sides by 14/29, eliminating the 29/14 on left
c = 7 * 14/29
c = 98/29 = 3 11/29

how many legs do 10 people have? if two people dont have legs. one person has 3 legs and one person has one leg. and mary has a
Ganezh [65]
So here is the answer. Normally, 10 people have 20 legs since each person has 2 legs each. But given the scenario that two people don't have legs, this would mean 20 minus 4, is 16 legs. Then one person has 3 legs, 16 plus 3 and it is 19. And then, another person has one leg, 19 plus 1 is 20. Therefore, the total legs would still be 20. Hope this helps. The dog does not count.

The following is an account for a production department, showing its costs for one month:
deff fn [24]

Answer:

option (b)  $9,360

Step-by-step explanation:

Given:

Goods in Process Inventory

Balance = $6,300

Direct materials = $22,500

Direct labor = $17,100

Overhead = $11,700

The cost of units in ending goods in process inventory = $5,490

The cost of started and completed units = $42,750

Now,

The cost of total Goods in Process Inventory will be

= Balance + Direct materials + Direct labor + Overhead

= $6,300 + $22,500 + $17,100 + $11,700

= $57,600

also,

Cost of units to be transferred out

= cost of total Goods in Process Inventory - ( cost of units in ending goods in process inventory )

= $57,600 - $5,490

= $52,110

Thus,

Cost of Completed Goods in Beginning Inventory

= Cost of units to be transferred out - cost of started and completed units

= $52,110 - $42,750

= $9,360

Hence, the answer is option (b)  $9,360
