<h2>Answer : Option A) 1 foot/second</h2><h3>Explanation :</h3>

If we consider that the plates are placed 2 ft apart and there has to be 1800 meals that needs to be delivered in an hour.

so if we multiply 2 ft and 1800 meals that is delivered in 1 hour,we get 2 X 1800 = 3600 meals in an hour.

If we try to accommodate the plates at each ft then there will be 3600 meals delivered in 1 hour.

we know that 1 hour has 3600 seconds in it.

So, here the distance is 1 ft, and speed has to be determined time is 1 hour = 3600 seconds

3600 meals / 3600 seconds = 1 foot per second.

OR 1800 meals set at 2 ft apart in 3600 seconds will give the speed of the belt as 1 foot per second.

(1 ft = speed X 1 hour)

<h2>so, the speed also will be 1 foot per second. </h2>

Mamont248 [21]

Answer:

Instructions are listed below

Explanation:

Giving the following information:

She has a choice of receiving a payment of $160,000 immediately or of receiving deferred perpetuity with $10,000 annual payments, the first payment occurring in exactly four years.

A) i= 5%

First, we need to determine the value of the perpetuity four years from now.

Perpetuity= 10,000/0.05= 200,000

Now, we can calculate the present value:

PV= 200,000/(1.05^4)= $164,540.50

B) i= 6%

Perpetuity= 10,000/0.06= $166,666.67

PV= $166,666.67/1.06^4= $132,015.61

C) She should consider her necessities of cash and the value of the products she can purchase now.

Basile [38]

Answer:

Hilary is a retired teacher who lives in Miami and does some consulting work for extra cash. At a wage of $50 per hour, she is willing to work 10 hours per week. At $65 per hour, she is willing to work 19 hours per week.

Using the midpoint method, the elasticity of Hilary’s labor supply between the wages of $50 and $65 per hour is approximately 2.37 , which means that Hilary’s supply of labor over this wage range is elastic.

Explanation:

Midpoint elasticity = (Change in labor supplied / Average labor supplied) / (Change in wage rate / Average wage rate)

= [(19 - 10) / (19 + 10) / 2] / [$(65 - 50) / $(65 + 50) / 2]

= [9 / (29 / 2)] / [15 / (115 / 2)]

= (9 / 14.5) / (15 / 57.5)

= 0.62/0.26

Midpoint elasticity = 2.37

Once elasticity is greater than 1, supply of labor is Elastic.
