The cash flows for this project will be -$560,450 (negative amount indicated by a minus sign).

To calculate the cash flows for this project, we need to consider the initial investment, operating cash flows, and terminal cash flows over the project's life.

Initial Investment:

Research and development cost: -$400,000

Machine cost: -$200,000

Shipping and installation cost: -$50,000

Net working capital increase: -$100,000

Total Initial Investment: -($400,000 + $200,000 + $50,000 + $100,000) = -$750,000

Operating Cash Flows:

The operating cash flows include revenue, costs, and depreciation for each year.

Revenue: $600,000 per year

Costs: $250,000 per year

Depreciation: Calculated using MACRS depreciation method for 7-year class life.

Year 1:

Depreciation: $200,000 (rounded to the nearest dollar) [MACRS depreciation for Year 1]

Operating Cash Flow: $600,000 - $250,000 - $200,000 = $150,000

Year 2:

Depreciation: $320,000 (rounded to the nearest dollar) [MACRS depreciation for Year 2]

Operating Cash Flow: $600,000 - $250,000 - $320,000 = $30,000

Year 3:

Depreciation: $192,000 (rounded to the nearest dollar) [MACRS depreciation for Year 3]

Operating Cash Flow: $600,000 - $250,000 - $192,000 = $158,000

Terminal Cash Flows:

Terminal cash flow includes the salvage value of the machine and the tax effect of selling the machine.

Salvage Value: $75,000

Tax Effect of Salvage Value: Taxable gain or loss on the sale of the machine = (Selling price - Book value)

Book Value: Accumulated depreciation at the end of Year 3 = $200,000 + $320,000 + $192,000 = $712,000

Selling price: $75,000

Taxable gain or loss: $75,000 - $712,000 = -$637,000

Tax on gain or loss: Tax rate (35%) * Taxable gain or loss = 0.35 * (-$637,000) = -$223,450

Terminal Cash Flow: Salvage Value + Tax on gain or loss = $75,000 + (-$223,450) = -$148,450

Now, let's sum up all the cash flows:

Cash Flows = Initial Investment + Operating Cash Flows + Terminal Cash Flow

Cash Flows = -$750,000 + $150,000 + $30,000 + $158,000 + (-$148,450)

Cash Flows = -$560,450

Therefore, the cash flows for this project will be -$560,450 (negative amount indicated by a minus sign).

Answer:

Side 3 = a - 2

Step-by-step explanation:

Perimeter of a ∆ = sum of all the sides of a triangle

Perimeter of the given ∆ = 6a + 3 units

Side 1 = 2(a + 3)

Side 2 = 3a - 1

Side 3 = ?

Therefore:

Side 3 = Perimeter - sum of side 1 and 2

Thus:

Side 3 = 6a + 3 - [2(a + 3) + (3a - 1)]

Side 3 = 6a + 3 - [2a + 6 + 3a - 1]

Side 3 = 6a + 3 - [5a + 5]

Side 3 = 6a + 3 - 5a - 5

Side 3 = a - 2

The cost of one shirt is $20.75.

Step-by-step explanation:

Total Cost/3 Shirts = The Cost of 1 Shirt

62.25/3 = 20.75

Answer:

1)  46.64

2)  17.75

3)  414.69

Step-by-step explanation:

13^2 -5^2=sqrt2172=46.64

22^2-13^2=sqrt315=17.75

V=πr2h

11/3=π·62·11

11/3≈414.69

Step-by-step explanation:

I assume it means the task is filled completely.

diameter = 2.1 m

therefore, radius = diameter/2 = 2.1/2 = 1.05 m

height = 4 m

volume of a cylinder is

ground area × height, so

pi×r² × height = pi×1.05²×4 = 13.8544236... m³

1 cm³ is 1g

for 1 kg (remember, "k" stands for "kilo" and means 1000) we need therefore 1000 cm³ (which is a cube of 10 cm side length).

how many cm³ are in 13.8544236... m³ ?

1 m = 100 cm

1 m² = 1 m × 1 m = 100×100 = 10,000 cm²

1 m³ = 1 m × 1 m × 1 m = 100×100×100 = 1,000,000 cm³

that means a factor of 1,000,000 !

so, the volume of the cylinder is

13.8544236... × 1,000,000 = 13,854,423.6... cm³

to get the mass of kg of that much water we need now to divide by 1000 :

13,854,423.6... / 1000 = 13,854.4236... kg

which is, by the way, 13.8544236... tons.

yes, 1 m³ of water is 1 ton ...

I don't know, if you need to round the result.

if you e.g. only need full kg, then the answer would be

13,854 kg.

The expected value of the f-ratio is the mean value

On average, the expected value for the f-ratio is 1.00 if the null hypothesis is true

From the question, we understand that the null hypothesis is true and the distribution is the F-ratio

The above scenario means that:

The variance of the top and the bottom ratio are the same

When the ratios are the same and the null hypothesis is accepted, then the expected value is 1.00

The fraction of a pound of ham that each sandwich has for the case when Mrs Johson used 12 pounds of ham to make 3 sandwiches is 4 pound per ham. or 4/1

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.

Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.

Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.

Thus, [tex]a \div b =[/tex] a divided in b equal parts.

Also, we can write: [tex]a \div b = a \times \dfrac{1}{b}[/tex]

(it is since a = a times 1 so [tex]a/b = 1 \times (a/b) = (1/b) \times a[/tex])

For this case, we're specified that:

12 pound of ham is divided in 3 parts for 3 sandwiches (assuming equally divided).

That means:

Amount of ham each sandwich gets = 12 divided by 3 = 12/3 = 4 pounds.

To find the fraction of a pound of ham that is on each sandwich, we find what part of a pound is 4 pounds.

If we take 4 times a pound, then we get 4 pounds.

Thus, 4 of a pound = 4 pound

In fraction, we have: 4 pounds = 4/1 fraction of a pound.

Thus, the fraction of a pound of ham that each sandwich has for the case when Mrs Johson used 12 pounds of ham to make 3 sandwiches is 4 pound per ham. or 4/1 fraction of a pound

Answer:

Let's first find the area of the rectangle/rectangle,

we can do this by combining their lengths as a whole

or

we can individually find their area.

Let's find the area of the individual shapes, upper rectangle;

(using the formula)

A = l x w

Where 'l' represents the length and 'w' stands for the width.

Plug in what you know:-

A = 27(24)

A = 648 square feet is the area of the upper rectangle.

Now, the lower rectangle:

A = l x w

Plug in what you know:-

A = 27(32)

A = 864 square feet is the area of the lower rectangle.

Now we find the area of the triangle beside;

(using the formula)

A = BH x 1/2

Where 'B' represents the base, 'H' the height, and 1/2 means to simply divide the product of those two lengths(base x height) by 2.

Plug in what you know:

A = BH x 1/2

A = 18(32) x 1/2

A = 576 x 1/2

A = 576/2

A = 288 square feet is the area of the triangle beside.

Add up all the areas we've gathered so far:

648 + 864 + 288

= 1,800 square feet is the area of the patio

Answer:

The total monthly charge if one uses 769 minutes is $68.65

Step-by-step explanation:

Example:  If we are at x = 310, y = 45.50 and we use one more

               minute, x goes up by 1, y increases by .05, putting us

               at x = 311, y = 45.55.  Thus, usage of 311 minutes

               incurs a monthly cost of $45.55.

The y intercept is the point where x = 0.

That point on our equation is (0, 30)

This means that if zero minutes are used during the month,

the total charge for the month will be $30... the flat fee.

c)  Find total monthly cost for using 769 minutes

y = .05x + 30

y = .05(769) + 30

y = 38.45 + 30

y = $68.65

Let the vertices of the prism be A, B, C, D, E, F, G, and H. (Refer to image).

From the image, we can tell that the faces of the prism are:

ABFG    HDCE     FBCE     GADH     GFEH    ABCD

Surface area formula:

[tex]\text{Surface area = Sum of the area of it's faces}[/tex]

The faces are ABFG, HDCE, FBCE, GADH, GFEH, and ABCD (Previous Part)

[tex]\implies \text{SA = A(ABFG) + A(HDCE) + A(FBCE) + A(GADH) + A(GFEH) + A(ABCD)}[/tex]

If we look at the prism carefully, we can tell that:

ABFG = DCEH

GADH = FBCE

GFEH = ABCD

Therefore, the new equation is:

[tex]\implies \text{SA = 2[A(ABFG)] + 2[A(GADH)] + 2[A(GFEH)]}[/tex]

If we look carefully, we can see that GADH and ABFG are rectangles. Therefore, their areas will be length multiplied by width. Now, substitute the dimensions of the rectangles in the surface area.

[tex]\implies \text{SA} = 2[4 \times 4] + 2[2.5 \times 4] + \text{2[A(GFEH)]}[/tex]

The area of a parallelogram is the base multiplied by the height.

[tex]\implies \text{SA}= 2[4 \times 4] + 2[2.5 \times4] + 2[4 \times 2]}[/tex]

Finally, simplify the equation to determine the surface area.

[tex]\implies \text{SA} = 2[16] + 2[10] + 2[8][/tex]

[tex]\implies \text{SA} = 32 + 20 + 16[/tex]

[tex]\implies \boxed{\text{SA = 68 m}^{2} }[/tex]
