Tje number of items in the ratio 8:27, proportioned according to the total number of items sent (1225), is 280 items in the 8 part and 945 items in the 27 part.

To find out how many items there are in 1 part of the ratio, we need to add together the two parts of the ratio. In this case, 8+27 = 35.

To proportion the items according to the ratio, we need to divide the total number of items (1225) by the number of parts in the ratio (35).

This gives us:

1 part of the ratio = 1225 / 35 = 35

To find out how many items there are in each part of the ratio, we need to multiply this value by the corresponding part of the ratio.

For the part that corresponds to 8, we have:

8 parts of the ratio = 8 x 35 = 280 items

For the part that corresponds to 27, we have:

27 parts of the ratio = 27 x 35 = 945 items

Therefore, the number of items in the ratio 8:27, proportioned according to the total number of items sent (1225), is 280 items in the 8 part and 945 items in the 27 part.

A quadratic model for the data is y = -0.0076x² + 0.6915x + 14.711.

The fuel economy at 80 mph is 21.39.

In this scenario, the speed (x) would be plotted on the x-axis of the scatter plot while the fuel economy (y) would be plotted on the x-axis of the scatter plot.

By critically observing the scatter plot (see attachment) which models the relationship between the speed (x) and fuel economy (y), a quadratic model for the line of best fit is given by:

y = -0.0076x² + 0.6915x + 14.711

When the speed (x) = 80 mph, the fuel economy (y) is given by;

The journal entry to record the sale of the equipment would be:Cash $105,800,Loss on Sale of Equipment $35,650,Equipment $212,000

Accumulated Depreciation $66,000

How to solve the question?

a. To calculate the book value of the equipment at December 31 of the fifth year, we need to determine the accumulated depreciation for the first five years. The annual depreciation expense is calculated as follows:

Depreciation Expense = (Cost - Residual Value) / Useful Life

Depreciation Expense = ($212,000 - $14,000) / 15

Depreciation Expense = $13,200 per year

The accumulated depreciation for five years is therefore:

Accumulated Depreciation = Depreciation Expense x Number of Years

Accumulated Depreciation = $13,200 x 5

Accumulated Depreciation = $66,000

The book value of the equipment at December 31 of the fifth year is calculated as follows:

Book Value = Cost - Accumulated Depreciation

Book Value = $212,000 - $66,000

Book Value = $146,000

b.

To record depreciation for the three months until the sale date, we need to calculate the depreciation expense for the sixth year. The annual depreciation expense remains the same at $13,200, but since the equipment was sold on April 1, we need to prorate the depreciation for the first three months of the year.

Depreciation Expense for the Sixth Year = Depreciation Expense x (Months Remaining / 12)

Depreciation Expense for the Sixth Year = $13,200 x (9 / 12)

Depreciation Expense for the Sixth Year = $9,900

The journal entry to record depreciation for the three months until the sale date would be:

Depreciation Expense $9,900

Accumulated Depreciation $9,900

To record the sale of the equipment, we need to compare the sale price to the book value of the equipment at the time of the sale.

The book value of the equipment at the time of the sale is calculated as follows:

Book Value = Cost - Accumulated Depreciation

Book Value = $212,000 - ($13,200 x 5.25)

Book Value = $141,450

Since the sale price of $105,800 is less than the book value of $141,450, we need to record a loss on the sale of the equipment. The journal entry to record the sale of the equipment would be:

Cash $105,800

Loss on Sale of Equipment $35,650

Equipment $212,000

Accumulated Depreciation $66,000

The cash received from the sale is debited, and the difference between the sale price and the book value is recorded as a loss on the sale of the equipment. The equipment and its accumulated depreciation are removed from the books.

Answer:

9/13

Step-by-step explanation:

P(odd or less than 5) = number of odd cards + number of cards less than 5 / total number of cards

P(odd or less than 5) = (20 + 16) / 52

P(odd or less than 5) = 36 / 52

P(odd or less than 5) = 9 / 13

Therefore, the probability of picking an odd card or a card less than 5.

The distance traveled by the wheel when it turns 20 times is 150.7964 feet.

What is circumference?

The circumference of a wheel can be calculated as:

Circumference = 2 x π x radius

where π (pi) is a mathematical constant approximately equal to 3.14159.

The distance traveled by a wheel when it turns is equal to the circumference of the wheel multiplied by the number of times it turns.

Given that the radius of the wheel is 1.2 feet, the circumference of the wheel is:

Circumference = 2 x π x radius

Circumference = 2 x 3.14159 x 1.2

Circumference = 7.53982 feet (rounded to 5 decimal places)

Therefore, each time the wheel turns, it travels a distance of 7.53982 feet. To find the distance traveled when the wheel turns 20 times, we can multiply the distance traveled each time by the number of times the wheel turns:

Distance traveled = Circumference x Number of turns

Distance traveled = 7.53982 feet x 20

Distance traveled = 150.7964 feet (rounded to 4 decimal places)

Therefore, the distance traveled by the wheel when it turns 20 times is 150.7964 feet.

there are 133,784,560 ways to draw 7 cards from a standard deck of 52 cards.

How to solve the question?

The number of ways to draw 7 cards from a standard deck of 52 cards can be calculated using the combination formula, which is:

C(52, 7) = 52! / (7! * (52-7)!)

where "!" represents the factorial function.

To simplify this expression, we can use the property that n! / k! = n * (n-1) * (n-2) * ... * (n-k+1) for positive integers n and k such that k ≤ n.

Using this property, we can rewrite the above expression as:

C(52, 7) = (52 * 51 * 50 * 49 * 48 * 47 * 46) / (7 * 6 * 5 * 4 * 3 * 2 * 1)

Simplifying this expression, we get:

C(52, 7) = 133,784,560

Therefore, there are 133,784,560 ways to draw 7 cards from a standard deck of 52 cards.

To understand why this is the case, we can think of each draw as a separate event with no replacement. The first card can be drawn in 52 ways, the second card can be drawn in 51 ways (since one card has already been drawn), the third card can be drawn in 50 ways (since two cards have already been drawn), and so on. Therefore, the total number of ways to draw 7 cards is the product of the number of ways to draw each individual card, which is 52 * 51 * 50 * 49 * 48 * 47 * 46. However, since the order in which the cards are drawn does not matter, we need to divide by the number of ways to arrange 7 cards, which is 7 * 6 * 5 * 4 * 3 * 2 * 1 (i.e., 7 factorial). This gives us the final answer of 133,784,560.

We are given the system of equations:

y = 3x

y = 6x + 3

We can use substitution to solve this system. Since both equations are equal to y, we can set them equal to each other:

3x = 6x + 3

Subtracting 3x from both sides, we get:

0 = 3x + 3

Subtracting 3 from both sides, we get:

-3 = 3x

Dividing both sides by 3, we get:

x = -1

Now that we know x, we can use either equation to find y. Let's use the first equation:

y = 3x = 3(-1) = -3

Therefore, the solution to the system of equations is (-1, -3).

To check our solution, we can substitute these values back into both equations:

y = 3x gives us -3 = 3(-1), which is true

y = 6x + 3 gives us -3 = 6(-1) + 3, which is also true

Therefore, our solution is correct.

We can also plug in the other given points to check that they do not satisfy both equations, which means they are not solutions to the system.

The surface area of the cylinder is approximately 3015.93square inches when rounded to the nearest hundredth.

To find the surface area of a cylinder, we need to add the areas of the top and bottom circles, and the area of the lateral surface, which is the curved part of the cylinder.

The formula for the surface area of a cylinder is:

S.A. = 2πr² + 2πrh

where r is the radius of the cylinder, h is the height, and π is approximately equal to 3.14.

Given that the diameter is 32 inches, we can find the radius by dividing by 2:

r = d/2 = 32/2 = 16 inches

Now we can substitute the values into the formula and simplify:

S.A. = 2πr² + 2πrh

S.A. = 2π(16)² + 2π(16)(14)

S.A. = 2π(256) + 2π(224)

S.A. = 512π + 448π

S.A. = 960π

To approximate the answer to the nearest hundredth, we can use the value of π rounded to two decimal places (3.14):
