a) Jill receives £45
b) Jack receives £20 the following Christmas
c) Jack will be 5/4 years old, which is equivalent to 1 year and 3 months when he receives £25 from Uncle Fred.
Explain the term years
Years are a unit of time measurement used to quantify the duration of one complete orbit of the Earth around the sun. A year consists of 365 days, except in a leap year when an extra day is added. The concept of a year is used in various fields, including astronomy, geology, and history.
According to the given information
(a) Let's first find the total ratio of their ages:
1 + 3 = 4
So Jack's share will be:
1/4 x £60 = £15
And Jill's share will be:
3/4 x £60 = £45
Therefore, Jill receives £45.
(b) The next Christmas, Jack will be 2 and Jill will be 4. We can use the same ratio to find Jack's share:
2/6 x £60 = £20
So Jack receives £20.
(c) Let x be the age of Jack when he receives £25 from Uncle Fred. We know that:
1/4 x £60 = £25
Multiplying both sides by 4/60, we get:
x = 5/4
So Jack will be 5/4 years old, which is equivalent to 1 year and 3 months, when he receives £25 from Uncle Fred.

A cone has a radius of 6 m and a height of 24 m. What is the volume of the cone in terms of π? 864π m3 432π m3 288π m3 144π m3
The volume of the cone is 288π m³. Hence, the answer is option C, 288π m³.
What is cone?A cone is a shape created by connecting all the points of a circular base (which does not contain the apex) to a common point known as the apex or vertex using a series of line segments or lines. The height of the cone is determined by measuring the distance between its vertex and base.
The formula for the volume of a cone is given by V = (1/3)πr²h, where r is the radius and h is the height.
Substituting the given values, we get:
V = (1/3)π(6²)(24)
V = (1/3)π(36)(24)
V = (1/3)(864π)
V = 288π
Therefore, the volume of the cone is 288π m³.
Hence, the answer is option C, 288π m³.

c. Symmetric with respect to the origin
Answer:
To determine if the given equations are symmetric with respect to the origin, we need to check if replacing x with -x and y with -y results in the same equation.
For the equations given:
y=7x-4 is not symmetric with respect to the origin since replacing x with -x and y with -y gives y=-7x+4, which is not the same equation.
y= -x+7 is not symmetric with respect to the origin since replacing x with -x and y with -y gives y=x-7, which is not the same equation.
y = -7x^2 is symmetric with respect to the origin since replacing x with -x and y with -y gives -y = -7(-x)^2, which simplifies to -y = -7x^2. Thus, the equation remains the same.
y = 6x^2 - 9 is not symmetric with respect to the origin since replacing x with -x and y with -y gives -y = 6(-x)^2 - 9, which simplifies to -y = 6x^2 - 9. Thus, the equation is not the same.
x=1/4 y^2 is not symmetric with respect to the origin since replacing x with -x and y with -y gives -x = 1/4 (-y)^2, which simplifies to -x = 1/4 y^2. Thus, the equation is not the same.
x = -y^2 + 9 is symmetric with respect to the origin since replacing x with -x and y with -y gives -x = -(-y)^2 + 9, which simplifies to -x = -y^2 + 9. Thus, the equation remains the same.
y=-1/6 x^3 is symmetric with respect to the origin since replacing x with -x and y with -y gives -y=-1/6(-x)^3, which simplifies to -y=-1/6 x^3. Thus, the equation remains the same.
y=x^3-1 is not symmetric with respect to the origin since replacing x with -x and y with -y gives -y=(-x)^3-1, which simplifies to -y=-x^3-1. Thus, the equation is not the same.
y=sqrt(x) is not symmetric with respect to the origin since replacing x with -x and y with -y gives -y=sqrt(-x), which is not the same equation.
y=sqrt(x)-6 is not symmetric with respect to the origin since replacing x with -x and y with -y gives -y=sqrt(-x)-6, which is not the same equation.
Therefore, the only equation that is symmetric with respect to the origin is y = -7x^2.

Use the traditional method to test the given hypothesis. Assume that the population is normally distributed and that the sample has been randomly selected. Select the appropriate response. With separate lines at the checkouts, a store manager finds that the standard deviation for the waiting times on Monday mornings is 5.7 minutes. After switching to a single waiting line, he finds that for a random sample of 29 customers the waiting times have a standard deviation of 4.9 minutes. Use a 0.025 significance level to test the claim that with a single line, waiting times vary less than with separate lines. Select the correct test statistic and critical value.
Test statistic: x^2 = 18.462. Critical value: x^2 = 15.308
Test statistic: x^2 = 20.692. Critical value: x^2 = 15.308

What is the formula to calculate weighted average? What is the difference between ROR and weighted return? Please help i'm stuck and my brain hurts.
The formula and the differences are shown below
What is the formula to calculate weighted average?The formula to calculate weighted average is:
weighted average = (w1x1 + w2x2 + ... + wnxn) / (w1 + w2 + ... + wn)
Where x1, x2, ..., xn are the values being averaged, and w1, w2, ..., wn are their corresponding weights.
The weighted average gives more importance or weight to certain values than others.
The weights can represent the relative importance, significance, or contribution of each value to the final average.
What is the difference between ROR and weighted return?The main difference between ROR and weighted return is that ROR measures the return of a single investment, while weighted return measures the return of a portfolio or investment that is composed of multiple assets with different weights.
Weighted return takes into account the relative importance of each asset or security in the portfolio, while ROR does not consider the impact of other investments.

The magnitude, M, of an earthquake is represented by the equation M=23logEE0 where E is the amount of energy released by the earthquake in joules and E0=104.4 is the assigned minimal measure released by an earthquake. Which equation could be used to find the amount of energy released by an earthquake with a magnitude of 2.7? Select the correct answer below: 4.05=E104.4 104.05=E104.4 104.05E=104.4 104.05=104.4E 104.05E=104.4
Using the magnitude formula we know the amount of energy released by an earthquake with a magnitude of 5.5 is 4.5 * 10¹².
What is Magnitude?The magnitude or size of a mathematical item defines whether it is larger or smaller than other objects of the same kind in mathematics.
Formally speaking, the size of an object is the visible outcome of an ordering—of the class of objects to which it belongs.
The most frequent way to gauge an earthquake's size is through its magnitude.
It is a gauge for the magnitude of an earthquake's sole source.
As a result, it is the same regardless of how or where you view it, and the following computation can be made:
So, in the given situation we will be using the formula:
M = 2/3 log E/E₀
Where E is the power released in Joules and x, the minimal measure released by such an earthquake shall be allotted to.
Assuming 5.5, the same magnitude is given when the above equation is used:
M = 2/3 log E/E₀
5.5 = 2/3 log (E/10⁴°⁴)
8.5 = log (E/10⁴°⁴)
10⁸°⁵ = E/10⁴°⁴
E = 10⁴°⁴ * 10⁸°⁵
E = 4.5 * 10¹²
Therefore, using the magnitude formula we know the amount of energy released by an earthquake with a magnitude of 5.5 is 4.5 * 10¹².

100 POINTS AND BRAINLIEST!!!! Uncle Fred gives his nephew, Jack, and niece, Jill, £60 between them every year
at Christmas. He splits it between them in the ratio of their ages.
(a) The first time he does this Jack is 1 and Jill is 3. How much does Jill
receive?
(b) How much does Jack receive the following Christmas?
(c) How old will Jack be when he receives £25 from Uncle Fred at Christmas?
Answer:
(a) The total ratio is 1 + 3 = 4, so Jill's share is (3/4) of £60:
Jill's share = (3/4) × £60 = £45.
(b) The ratio of their ages remains the same, so if Jack is one year older, Jill is also one year older. Therefore, Jill's age is 4 and Jack's age is 2, and Jack's share is (2/4) of £60:
Jack's share = (1/2) × £60 = £30.
(c) Let x be the age of Jack when he receives £25 from Uncle Fred. According to the problem, Jill is always two years older than Jack. Therefore, when Jack is x years old, Jill is x + 2 years old. The ratio of their ages is x : (x + 2), and this ratio is equal to 5/7 (25 pounds is 5/7 of 35 pounds, which is the total amount that they will receive). We can write an equation to solve for x:
x/(x+2) = 5/7
7x = 5(x + 2)
7x = 5x + 10
2x = 10
x = 5
Therefore, Jack will be 5 years old when he receives £25 from Uncle Fred at Christmas.
A) £45 because Jill will get 3/4 and Jack will get 1/4. To check our work, 60 divided by 4 is 15. 15 times 3 is 45 and 15 times one is 15.
B) £30 because it is a new year, both nephews will increase by one year. Now Jill is 4 and Jack is 2. So each kid will get half the share. 2 divided by 4 is 0.5 which is half of one. Half of 60 is 30.
C) 5 years Jill will always be 2 years older than Jack; this shows us that if some more years pass, Jill will be 7 and Jack will be 5 —> 1/4 x £60 = £25 Multiplying both sides by 4/60, we get:x = 5/4. This means Jack will be 5.

The value of (a) in given triangle is approximately 7.44 cm.
What do you mean by triangle?A triangle is a three-sided polygon consisting of three sides and three vertices. The most important property of a triangle is that the sum of its interior angles is 180 degrees.
Let ΔABC is a triangle
Given ∠ B = 75°
∠ C = 31.8°
AB = 12cm
AC = 22cm
find BC = ?
We can use the law of cosines to solve for BC:
BC² = AB² + AC² – 2(AB)(AC)cos(B)
We know that angle B = 75 degrees, so we can substitute:
BC² = 12² + 22² - 2(12)(22)cos(75)
Evaluating cos(75) with a calculator, we get:
BC² ≈ 144 + 484 - 572.59
BC² ≈ 55.41
Taking the square root of both sides gives us:
BC ≈ 7.44
