2.8, 3.4, 4.0, 4.6, . . . Write an equation for the nth term of the arithmetic sequence. Then find a50.
vova2212 [387]

Answer:

a_n = 2.2 + 0.6 n

a_50 = 32.2

Step-by-step explanation:

What's the common difference of this series?

a_1 = 2.8

a_2 = 3.4

Common difference = a_2 - a_1 = 3.4 - 2.8 = 0.6.

Expression for the nth term:

a_n = a_1 + (n - 1) \cdot\text{Common Difference} \\\phantom{a_n } = 2.8 + 0.6 \; (n-1) \\\phantom{a_n} = 2.8 + 0.6 \; n - 0.6\\\phantom{a_n} = 2.2 + 0.6\; n

n = 50 for the fiftieth term. Therefore

a_{50} = 2.2 + 0.6 \times 50 = 32.2.

Consider a room that is 20 ft long, 15 ft wide, and 8 ft high. For standard sea level conditions, calculate the mass of air in t
irga5000 [103]

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

The following normal account balances were found on the general ledger before closing entries were prepared: Revenue $800 Cash $
Virty [35]

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

Which expression is equivalent to (3b +2r) + (4b + r )
VladimirAG [237]

Answer:

Step-by-step explanation:

The one that looks most closely to this.

(3b + 2r) + (4b + r)                 Remove the brackets.

3b + 2r + 4b + r                     Rewrite so the terms are close to each other.

3b + 4b + 2r + r                     Combine

7b + 3r    or

3r + 7b

One of the two of these can be given as an answer. Please give choices if you want me to give an exact answer.
