Answer:
5.70456 slug
Step-by-step explanation:
Data provided in the question:
Dimensions of the room = 20 ft long, 15 ft wide, and 8 ft high
Now,
Volume of the room = 20 × 15 × 8
or
Volume of the room = 2400 ft³
we know,
Density of air = 0.0023769 slug/ft³
Therefore,
Mass of air in the room = Volume × Density
= 0.0023769 × 2400
= 5.70456 slug
Answer:
$ 7250
Step-by-step explanation:
Data provided:
Revenue = $800
Cash = $500
Expenses = $400
Accounts Receivable = $350
Capital = $7,500
Withdrawals = $1,000
Balance in the cash account
=(Revenue+Cash + Accounts Receivable + Capital )-(Expenses + Withdrawals)
on substituting the values, we get
Balance in cash account = ( $ 800 + $ 350 + $ 7,500 ) - ( $ 400 + $ 1,000)
or
Balance in cash account = $ 8,650 - $ 1,400 = $ 7250
