If David, Malachy and Paul share some sweets in the ratio 4:3:3 then Paul get 7.2 number of sweets

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given that David, Malachy and Paul share some sweets in the ratio 4:3:3

All three shared 24 sweets together.

Let x be the number of sweets

4x+3x+3x=24

Add the like terms

10x=24

Divide both sides by 10

x=2.4

Now paul has 3x sweets so 3×2.4=7.2

Hence, Paul get 7.2 number of sweets

Answer:

20x² + 36x - 16

Step-by-step explanation:

Length = 5x+4

Width = 4x-4

Area = Length×Width

Area = (5x + 4)(4x - 4)

Area = 20x² - 20x + 16x -16

Area = 20x² - 4x - 16

Therefore 20x² - 4x - 16 is the correct answer.

Answer:

The diameter of a hat is 4.7 inches, so the distance around the hat using π = 3.14 would be 14.76 inches (4.7 x 3.14).

A soda company with a can radius of 3 and one fourth cm needs to replace its label; if it touches end to end without overlap, then the length will be 143 over 28 cm (3 1/4 x 22 / 7).

The circumference of a circle in terms of π when there is segment drawn from one point on the circle through center to another point labeled 7 yards would be 21.98π yards (2x(radius)xπ or 2x7yards×3 .14 ).

Finally, for given 91 .688 millimeters as circumference ,the radius should equal 29 .2 mm ((91 688mm)/(2 × pi)).

The circumferences for the examples are 14.76 inches, 143/14 cm, 14π yards, and the radius is 14.6 mm. Circumference is calculated with 2*π*r.

The circumference of a circle is calculated using the formula 2* π * radius.

1. For the hat, the radius would be half the diameter, hence 4.7/2 = 2.35 inches. Substituting these values into the circumference formula gives 2*3.14*2.35 = 14.76 inches.

2. For the soda can, the circumference is 2*π*r = 2*(22/7)*(3 1/4) = 2*(22/7)* (13/4) = 143/14 cm.

3. For a circle with a radius of 7 yards, the circumference would be 2*π*7 = 14π yards.

4. If the circumference is given as 91.688 mm, and we need to find the radius, we rearrange the circumference formula to find radius = Circumference / (2* π) =  91.688 / (2 * 3.14) = 14.6 mm.

The correct answer is option (D) "The graph shifts 7 units right and 8 units down".Explanation:To solve the given question, we need to use the rules for vertical and horizontal shifts, which are as follows:

Vertical Shift: y=f(x)+a moves the graph of f(x) upward if a > 0 and downward if a < 0.Horizontal Shift: y=f(x+a) moves the graph of f(x) left if a > 0 and right if a < 0.Now, let's transform the function f(x) into function g(x) and determine the shift required.The transformation of f(x) to g(x) is: g(x) = f(x - a) + bwhere a = horizontal shift and b = vertical shiftThe equation of the given functions is:f(x) = 1/(x − 2) and g(x) = 1/(x^(5/9))Let's set the equation of function f(x) in the standard form:y = 1/(x - 2)and the equation of function g(x) in the standard form:y = 1/(x^(5/9))

Now, we can observe that:To transform the graph of f(x) onto the graph of g(x), we need to shift the graph of f(x) right by 7 units and down by 8 units, which is given in option (D).Hence, the correct option is (D) "The graph shifts 7 units right and 8 units down".

The graph shifts 7 units right and 8 units down is the statement that describes the transformation of the graph of function f onto the graph of function g.Conclusion:Thus, we have determined the correct answer with an explanation and concluded that the correct option is (D) "The graph shifts 7 units right and 8 units down".

Step-by-step explanation:

0.313 milligrams (rounded to three decimal places) of plutonium-234 will be present after 3 days.

The half-life of plutonium-234 is 9 hours, which means that after every 9 hours, the amount of plutonium-234 will decrease by half.

To find the amount of plutonium-234 present after 3 days (72 hours), we can calculate the number of half-lives that have passed and use that information to determine the remaining amount.

Number of half-lives = time elapsed / half-life

In this case, the time elapsed is 72 hours, and the half-life is 9 hours.

Number of half-lives = 72 / 9 = 8

After 8 half-lives, the remaining amount will be:

Remaining amount = Initial amount * (1/2)^(number of half-lives)

Given that the initial amount is 80 milligrams, we can calculate the remaining amount:

Remaining amount = 80 * (1/2)^8

= 80 * (1/256)

≈ 0.3125 milligrams

Therefore, approximately 0.313 milligrams (rounded to three decimal places) of plutonium-234 will be present after 3 days.

d. Expected life in years of the depreciable asset. The acceptable way to express the useful life of a depreciable asset is in terms of the expected life in years.

The useful life refers to the period of time over which the asset is expected to contribute to the revenue-generating activities of a business.

While options a, b, and c may be relevant factors for certain specific assets (such as units produced, hours of productivity, or miles driven), they do not encompass the overall concept of useful life. Useful life is a broader measure that takes into account the anticipated duration of productive use, regardless of specific output or activity metrics.

Expressing the useful life in years provides a common standard for comparison and allows for consistency in depreciation calculations and financial reporting. It is a practical and widely accepted approach to estimating the lifespan of a depreciable asset.

It is worth noting that the estimated useful life in years may vary depending on the nature of the asset and industry practices. It is typically determined based on factors such as technological advancements, physical wear and tear, economic obsolescence, and the intended purpose of the asset.

The subspace has a basis consisting of two vectors, its dimension is 2.

The subspace is given by the set of all vectors in \(R^4\) of the form (a, b, c, d) such that a - 3b = c = 0. We can rewrite this as:

(a, b, c, d) = (3b, b, 0, d) = b(3, 1, 0, 0) + (0, 0, 0, d)

This means that any vector in the subspace can be written as a linear combination of the two vectors (3, 1, 0, 0) and (0, 0, 0, 1). Therefore, these two vectors form a basis for the subspace.

To see that they are linearly independent, suppose that:

c1(3, 1, 0, 0) + c2(0, 0, 0, 1) = (0, 0, 0, 0)

This implies that c1(3, 1, 0, 0) = (0, 0, 0, 0), which in turn implies that c1 = 0. Substituting this into the original equation, we get:

c2(0, 0, 0, 1) = (0, 0, 0, 0)

This implies that c2 = 0 as well. Therefore, the only linear combination of (3, 1, 0, 0) and (0, 0, 0, 1) that equals the zero vector is the trivial one, which means that these two vectors are linearly independent.

Since the subspace has a basis consisting of two vectors, its dimension is 2.

Yes, it is possible for a plot of a partial expansion of f[x] to share ink with the plot of f[x] all the way from -[infinity] to + [infinity].

Explanation:

We can approximate f(x) as a Fourier series, as follows:

\($$f(x) = \sum_{n=0}^{\infty}a_n\cos\left(\frac{n\pi x}{L}\right)+\sum_{n=1}^{\infty}b_n\sin\left(\frac{n\pi x}{L}\right)$$\)

If f(x) is an odd function, the cosine terms are gone, and if f(x) is an even function, the sine terms are gone.

We can create an approximation for f(x) using only the first n terms of the Fourier series, as follows:

\($$f_n(x) = a_0 + \sum_{n=1}^{n}\left[a_n\cos\left(\frac{n\pi x}{L}\right)+b_n\sin\left(\frac{n\pi x}{L}\right)\right]$$\)

For any continuous function f(x), the Fourier series converges uniformly to f(x) on any finite interval, as given by the Weierstrass approximation theorem.

However, if f(x) is discontinuous, the Fourier series approximation does not converge uniformly.

Instead, it converges in the mean sense or the L2 sense. The L2 norm is defined as follows:

\($$\|f\|^2 = \int_{-L}^{L} |f(x)|^2 dx$$\)

Hence, it is possible for a plot of a partial expansion of f(x) to share ink with the plot of f(x) all the way from -[infinity] to + [infinity].

The slope of the original line of the graph sis found to be 1 and the slope of perpendicular line is -1.

One of the line shown in the graph is passing through the points (0, -7) and (7, 0). Now we have to recall that the slope M of the line L passing from points (a, b) and (c, d) is given as,

M = (d-b)/(c-a)

Also, if the line L is perpendicular to line l, then the slope m of the line l will be given as,

m = -1/M.

So, now the slope of line L is,

M = (0-(-7))/(7-0)

M = 7/7

M = 1

The cost of 1 dozen eggs is $2.50.

Step-by-step explanation:

To find the cost of one dozen eggs, we need to determine the cost per egg and then multiply it by 12.

Given that 1.5 dozen eggs cost $3.75, we can divide the total cost by the number of dozens to find the cost per dozen.

3.75 divided by 1.5 equals $2.50.

Therefore, the cost of one dozen eggs is $2.50.

Among the given options, option B, $2.50, corresponds to the correct answer.

Option A, $2.25, is not the correct answer because it is lower than the calculated cost of $2.50.

Option C, $4.75, and option D, $5.50, are not the correct answers because they are higher than the calculated cost of $2.50.

Thus, the correct answer is B, $2.50.
