When adding one identical room to a pair of houses, the price increase for a house with 4000 sqft compared to a house with 1000 sqft is $150,000.

What is the basis of this problem?

We have two houses, one with a 4000 square foot floor plan and another with a 1000 square foot floor plan. Both of them are identical, and each of them is expected to receive an additional identical room. We must determine how much the price of the house with the 4000 square foot floor plan will increase compared to the house with the 1000 square foot floor plan when both of these are completed.

Let's start by identifying the amount of money needed to construct each house. The amount of money needed to construct the house with the 4000 square foot floor plan is $300,000, and the amount of money required to build the house with the 1000 square foot floor plan is $150,000.The cost of building per square foot in this case is therefore $75/sqft.

As a result, the price for a 4000 sqft house is: $75/sqft × 4000 sqft = $300,000On the other hand, the cost of constructing a 1000 sqft house is:$75/sqft × 1000 sqft = $75,000When each house gets an additional identical room, the increase in the cost of the room is $50,000. As a result, the price of the house with the 4000 square foot floor plan will increase by 4 times, or $200,000, whereas the price of the house with the 1000 square foot floor plan will increase by one, or $50,000. As a result, the price of a 4000 sqft house will be $300,000 + $200,000 = $500,000, whereas the price of a 1000 sqft house will be $150,000 + $50,000 = $200,000.

When we compare these two values, we obtain the following outcome: Suppose you add 1 identical room to a pair of houses. The two houses are identical except for square footage.

When we compare the two values, we get the following result: $500,000 - $200,000 = $300,000

Therefore, the price increase for a house with 4000 sqft compared to a house with 1000 sqft is $150,000.

a. The height of the golf ball at the instant it is hit is 0 feet.

b. The height of the golf ball 2.8 seconds after it is hit is approximately 62.72 feet.

c. It takes 4 seconds for the golf ball to hit the ground after it is hit.

a) To find the height of the golf ball at the instant it is hit, we need to evaluate the function h when t = 0.

Substituting t = 0 into the given equation, we get:

h = -16(0)² + 64(0) = 0

Therefore, the height of the golf ball at the instant it is hit is 0 feet.

b) To find the height of the golf ball 2.8 seconds after it is hit, we need to evaluate the function h when t = 2.8.

Substituting t = 2.8 into the given equation, we get:

h = -16(2.8)² + 64(2.8) ≈ 62.72

Therefore, the height of the golf ball 2.8 seconds after it is hit is approximately 62.72 feet.

c) To find how long it takes the ball to hit the ground after it is hit, we need to find the value of t when the height is 0.

Setting h = 0 in the given equation, we get:

0 = -16t² + 64t

0 = t(-16t + 64)

t = 0 or t = 4

Since the golf ball was hit upwards, we are only interested in the positive value of t, which is t = 4.

Therefore, it takes 4 seconds for the golf ball to hit the ground after it is hit.

The function is an exponential function of the form y = a * b^x, where "a" is the initial value and "b" is the common ratio.

Using the given table, we can see that:

- The initial value is y(0) = -2, so a = -2.

- To find the common ratio, we can divide any term by the previous term. For example:

 - b = y(1)/y(0) = (-10)/(-2) = 5

 - b = y(2)/y(1) = (-50)/(-10) = 5

 - and so on.

Since we get the same value of b for all the ratios, we can conclude that the common ratio is b = 5.

Therefore, the equation for the function shown in the table is: y = -2 * 5^x.

Answer:

50%

Step-by-step explanation:

There are 4 cards.  4 and 6 are not odd, which is 2 cards.

P(not odd) = number of cards that are not odd/ total number of cards

                   = 2/4 = 1/2 = .5 = 50%

An angle that is coterminal with -865° and has a measure between 0° and 360° is 75°. Since Angle b is coterminal with this angle, we can conclude that the measure of Angle b is 75°.

We must locate an angle that is coterminal with the -865° angle and has a measure between 0° and 360° in order to determine the size of angle b.

To do this, we can add or remove 360-degree multiples until we have an angle that is coterminal with -865° and is between 0° and 360°.

-865° + 360° = -505° (not between 0° and 360°)

-865° + 2(360°) = -145° (not between 0° and 360°)

-865° + 3(360°) = 75° (between 0° and 360°)

As a result, an angle with a measure between 0° and 360° that is coterminal with -865° is 75°. We can infer that Angle b's measure is 75° because it contaminates with this angle.

Answer: 1) C. 1.75

              2) C. 5.25

Step-by-step explanation:

For this first question, the answer is C. 1 3/4

First, you will need to calculate how many hours the 3/4-hour students studied versus the 1/4-hour students.

3/4 students: 3/4 · 3 = 9/4

1/4 students: 1/4 · 2 = 2/4

9/4 - 2/4 = 7/4 = 1 3/4

Therefore, your answer for the first question is C.

For the second question, the answer is C

We must calculate how many hours each group of students studied, then add them together. You can add or multiply in this situation.

1/4 students: 1/4 · 2 = 2/4 (No need for simplifying until the end.)

1/2 students: 1/2 · 5 = 5/2

3/4 students: 3/4 · 3 = 9/4

Now, let's change the 5/2 so we can add it to the other fractions.

5/2 ·2 = 10/4

Let's add.

2/4 + 10/4 + 9/4 = 21/4

Simplify.

21/4 = 5 1/4.

Therefore, answer choice C is correct.

Answer: Assuming the field is rectangular, the distance between the two corners diagonally can be calculated using the Pythagorean theorem, which states that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

In this case, the length and width of the field form the two sides of the right triangle, and the diagonal is the hypotenuse.

So, using the Pythagorean theorem:

Diagonal^2 = Length^2 + Width^2

Diagonal^2 = 80^2 + 60^2

Diagonal^2 = 6400 + 3600

Diagonal^2 = 10000

Diagonal = √10000

Diagonal = 100 yards

Therefore, the soccer player will have to kick the ball 100 yards to reach the opposite corner of the field.

The capitalized costs for 2017 is $55,000.

Capitalizing means adding the cost of an asset to its book value or cost basis. Not all costs can be capitalized.

Generally, only costs that increase an asset's useful life or productive capacity should be capitalized.

In this case, the building and truck were purchased in 2015 and have been capitalized.

The following costs incurred in 2017 should be analyzed to determine whether they should be capitalized or expensed:

Painting the building for $5,000 - This cost does not increase the useful life or productive capacity of the building.

It is considered a repair and maintenance expense and should be expensed.

Installing new windows in the building for $10,000 - This cost improves the building's insulation and prevents leaking.

It is considered a capital improvement that extends the useful life of the building. Therefore, it should be capitalized.

Installing a new conveyor system for $40,000 - This cost increases the productive capacity of the company's operations. It is considered a capital expenditure and should be capitalized.

Repainting the delivery truck for $1,000 - This cost does not increase the useful life or productive capacity of the truck. It is considered a repair and maintenance expense and should be expensed.

Installing a hydraulic lift system on the truck for $5,000 - This cost allows better handling of large loads and increases the productive capacity of the truck. It is considered a capital expenditure and should be capitalized.

Overhauling the truck's engine for $4,000 - This cost is a repair and maintenance expense and should be expensed.

Therefore, the capitalized costs for 2017 are

$10,000 (new windows in the building) + $40,000 (new conveyor system) + $5,000 (hydraulic lift system on the truck) = $55,000.

Answer: y = 4x + 1, 25 inches at 6 years old

Step-by-step explanation:

   Our y-intercept will be 1 (5 inches at a year old - 4 inches per year = 1) with a slope of 4 (4 inches a year). Our equation will look like this:

            y = 4x + 1

   Next, to solve for the length of the tusk at 6 years old, we will input this value of 6 and solve.

            y = 4x + 1 = 4(6) + 1 = 25 inches

   See attached for a graph.
