Answer:

Area of Shaded Region ≈ 0.23 cm^2

Step-by-step explanation:

Simple Question.

The diameter of the circle is 0.4 m, so the radius = 0.4/2 = 0.2 m.

The area of the circle = πr^2 = π(0.2)^2 = 0.04π

The area of the rectangle = 0.9*0.4 = 0.36

The area of the shaded region = 0.36 - 0.04π (π => 3.14) = 0.36 - 0.1256 = 0.2344 ≈ 0.23 cm^2

The Campbell Company is considering adding a robotic paint sprayer to its production line. The sprayer's base price is $1,020,00

1. The Year-0 net cash flow is -$1,061,500.

2. The net operating cash flows in Years 1, 2, and 3 are as follows:

Year 1: $288,750 ($386,000 x 1 - 0.25)

Year 2: $288,750 ($386,000 x 1 - 0.25)

Year 3: $288,750 ($386,000 x 1 - 0.25)

3. The additional Year-3 cash flow (i.e, the after-tax salvage and the return of working capital) is $468,750 {($599,000 x 1 - 0.25) + $19,500}.

4. The NPV of the project is ($13,139).

5. The machine should not be purchased because it does not yield a positive NPV.

<h3>What is the net present value?</h3>

The net present value (NPV) shows the difference between the present value of cash inflows and the present value of cash outflows over a period of time.

It is determined by calculating the present values of cash flows using their present value factors as below:

<h3>Data and Calculations:</h3>

Initial cash outlay = $1,061,500 ($1,020,000 + $22,000 + $19,500)

Salvage value = $599,000

Increase in net working capital = $19,500

Annual savings before tax = $386,000

Tax rate = 25%

Annuial savings after tax = $288,750 ($386,000 x 1 - 0.25)

<h3>Determination of Net Present Value (NPV):</h3>

Year Cashflows PV Factor Present Value

0 -$1,061,500 1 -$1,061,500

1 $288,750 0.901 $260,164

2 $288,750 0.812 $234,465

3 $288,750 0.731 $211,076

3 $468,750 0.731 $342,656

Net present value -$13,139

Thus, the project should not be undertaken by The Campbell Company due to the negative NPV that it yields.

Write y=5/8x +6 in standard form using intergers

Art [367]

Answer:

5x - 8y = -48

Step-by-step explanation:

Move 5/8x to the y side to get (-5/8)x + y = 6. Multiply both sides by -8 to get 5x - 8y = -48.

Can anyone answer this question please<br> 6[y-2]/7-12=2[y-7]/3

Kaylis [27]

Answer:

y =47.5.

Step-by-step explanation:

First eliminate the fractions by multiplying through by the LCM of 7 and 3 which is 21:

21* 6[y-2]/7-21*12 = 21*2[y-7]/3

18(y - 2) - 252 = 14(y - 7)

18y -36 - 252 = 14y - 98

18y - 14y = -98 + 36 + 252

4y = 190

y = 190/4

y = 47.5.

An electrical rm manufactures light bulbs that have a life span that is approximately normally distributed. The population stand

stira [4]

Answer:

The 't' test statistic = 1.46 < 1.69

The test of hypothesis is H 0 :μ = 800 is accepted

A sample of 30 bulbs are found came from average µ= 800

Step-by-step explanation:

Step 1:-

Given population of mean μ = 800

given size of small sample n =30

sample standard deviation 'S' = 45

Mean value of the sample χ = 788

Null hypothesis $H_{0} =$ µ =800

alternative hypothesis $H_{1} =$ µ ≠ 800

<u>Step 2</u>:-

The 't' test statistic t = $\frac{x-μ}{\frac{sig}{\sqrt{n} } }$

$t = \frac{788-800}{\frac{45}{\sqrt{30} } }$

t = $\frac{12}{8.215}$ = 1.4607

<u>Step 3</u>:-

The degrees of freedom γ = n-1 = 30-1 =29

From "t" value from table at 0.05 level of significance ( t = 1.69)

The calculated value t = 1.4607 < 1.69

Therefore The null hypothesis H_{0} ' is accepted.

<u>conclusion</u>:-

A sample of 30 bulbs are came found from average µ= 800

You borrow money for 4 years. The total amount that you repay is $7,840, which includes $840 in simple interest. How much was th

Lina20 [59]

Answer:

principal: $7000
interest rate: 3%

Step-by-step explanation:

amount repaid = principal + interest

$7840 = principal + $840

$7000 = principal . . . . . . . . subtract $840 from both sides of the equation

___

I = Prt

840 = 7000·r·4

840/(4·7000) = r = 0.03 = 3%

The principal was $7000; the interest rate was 3%.
