Answer:

0.066 cent

Explanation:

Efficiency (E) = Energy output (Eo)/Energy input (Ei)

Eo = E × Ei

E = 0.6

Ei = mass × acceleration due to gravity × height

mass = 100lbm = 100×0.45359kg = 45.359kg, height = 300ft = 300/3.2808 = 91.44m

Ei = 45.359×9.8×91.44 = 40646.7Ws = 40.6467kWs = 40.6467kWs × 1h/3600s = 0.011kWh

Eo = 0.6 × 0.011kWh = 0.0066kWh

1kWh = 10 cents

0.0066kWh = 0.0066×10 = 0.066 cent

Ymorist [56]

Answer:

i = 5.48%

Explanation:

We can use the following method to solve the given problem in the question.

Two consecutive 3 year CDs:

=10000 * (1+(0.05/4))^12 * (1+.(0.05/4))^12 = 13, 473.51

One 5 year CD and a 1 year CD:

=10000 * (1+(0.0565/4))^20 * (1+.(0.04/4))^4 = 13,775.75

13,775.75 is the greater.

The annual effective rate is

=10000 * (1+I)^6 = 13,775.75

i = 5.48%

1, xyz company cost function for the next four month is cost =500000+5Q A, find the BE dollar volume of sale is the selling pric
Temka [501]

Answer:

<u>Break Even point </u>Q = 500000

<u>Shut Down Point </u> P < 5

Explanation:

<u>Break Even point</u> is where Total Revenue = Total Cost.

Total cost = 500000 + 5Q, price = 6 (Given) , Total revenue = Price x quantity  

So, TR = TC implies : 500000 + 5Q = 6Q → 500000 = 6Q - 5Q

Q = 500000

<u>Shut Down Point </u>is where firm's Price is < its Average Variable Cost .  

AVC is the variable cost on per unit output, is found out by average of variable component of cost function. C = 500000 + 5Q implies variable cost = 5Q , so AVC = 5Q / Q = 5

So, the firm would shut down if its price would go below AVC , ie if P < 5

Setler [38]

Answer:

Production= 11,500 units

Explanation:

Giving the following information:

Estimated inventory (units), April 19,000

Desired inventory (units), April 30 18,000

Expected sales volume (units):

Area A 3,500

Area B 4,750

Area C 4,250

Total sales= 12,500

To calculate the production for April, we need to use the following formula:

Production= sales + desired ending inventory - beginning inventory

Production= 12,500 + 18,000 - 19,000

Production= 11,500 units

romanna [79]

Answer:

On January 1, 2015, Truesdale, Inc., purchased a piece of machinery for use in operations. The total acquisition cost was $33,000. The machine has an estimated useful life of 3 years and a salvage value of $3,000. Using the double-declining-balance method, depreciation for 2015 is approximately <u>$22,000</u>.

At December 31, 2016, using the double-declining-balance method, the book value of the machine is approximately <u>$7,333.33</u>.

Using the double-declining-balance method, depreciation for 2017 is approximately <u>$666.67</u>.

Explanation:

depreciation expense using double declining method 2015 = 2 x 1/3 x $33,000 = $22,000

depreciation expense using double declining method 2016 = 2 x 1/3 x $11,000 = $7,333.33

depreciation expense using double declining method 2017 = $3,666.67 - $3,000 = $666.67
