Explanation:

Connecting a resistor in series with battery will cause the battery voltage to drop.

voltage across resistor= 12-3.6= 8.4

Current in the circuit= 0.15A

V= IR

8.4= 0.15R

R= 56Ω

From the bunch of resistors, I will make a combination of 56Ω

Bond [772]

Answer:

a) 154054 gals

b) 20850 lb/day

c) 0.7392hr

d) 2.466day^-1

e) 7.23 lb/day-1000 ft^3

Explanation:

a)

$Vx = \frac{Qy(So - Se)}{1+kdQc}= \frac{5x10^{6}(0.6)(200-10)}{1+0.06(8)}=154054 gals$

b)

Dry mass = 5 MGD * (0.20) * (2500 mg/l) * 8.34 = 20850 lb/day

c)

Aeration period Q = $\frac{V}{Q} =\frac{154054}{5x10^{6} } =0.0308day=0.7392hr$

d)

$\frac{F}{M} =\frac{Q(So-Se)}{Vx}=\frac{5x10^{6}(200-10) }{154054(2500)}=2.466day^{-1}$

e)

BOD loading = $\frac{8.34(5)(200)}{154.054(7.48)} = 7.23 lb/day-1000 ft^{3}$

Hope this helps!

The “Sun-Star” Company has purchased new ofﬁce furniture for their ofﬁces at a retail price of $100,000. An additional $12,000 h

Zinaida [17]

Based on the cost of the furniture, the following are true:

a. $10,400.
b. $93,600
c. $20,800

<h3>Depreciation in second year</h3>

Depreciation per year = (Cost of furniture - Salvage value) / Useful life

Cost will include both the purchase price and the charge for insurance and shipping.

= (100,000 + 12,000 - 8,000) / 10

= $10,400

<h3>BV at end of first year</h3>

= Cost - Depreciation

= 104,000 - 10,400

= $93,600

<h3>BV after 8 years </h3>

= Cost - (Depreciation x 8 years )

= 104,000 - (10,400 x 8)

= $20,800

In conclusion, depreciation is $10,400 per year.
