24% of a value is £84. Work out the original value. Give your answer in pounds (£).
A 28-sided die exists rolled 3 times then the different possible outcomes exist £350.
What is meant by original value?The sales price of the property used as collateral for the mortgage, as stated in the contract, or the appraised value at the time the relevant residential mortgage transaction was completed, whichever is less, is referred to as the "original value" with respect to a residential mortgage transaction.
The value of a mortgaged property is determined by an appraisal that was done in conjunction with the loan's origination.
Based on the given conditions, formulate:
28 × 3 = 84 then
£84 / 24%
simplifying the above equation, we get
= £350
Therefore, different possible outcomes exist for £350.

The sum of three numbers is 20. The third is 3 more than 12 times the second. 9 times the first is 11 less than 10 times the second. Find the numbers.
A three-number total equals twenty. The third is three times as much as the second. From the equation numbers area 0.1, 1.2 and 17.4.
Given that,
A three-number total equals twenty.
The third is three times as much as the second.
11 less than 10 times the second is 9 times the first.
We have to find the numbers.
First take the 3 numbers as a,b and c
A three-number total equals twenty.
We can write as,
a+b+c=20→ equation(1)
The third is three times as much as the second.
c=12b+3→equation(2)
11 less than 10 times the second is 9 times the first.
9a=10b-11→equation(3)
Now,
From equation(3) we get,
a=(10b-11)/9=10/9b-11/9
From equation(2) we get,
c=12b+3
Substitute value a and c in equation(1),
10/9b-11/9+b+12b+3=20
10b-11+9b+108b+27=20×9
127b+16=180
127b=180-16
127b=164
b=164/127
b=1.2
Substitute the b value in equation (2) and (3)
Equation(2)
c=12b+3
c=12(1.2)+3
c=14.4+3
c=17.4
Equation(3)
a=10/9b-11/9
a=10/9(1.2)-11/9
a=1.3-1.2
a=0.1
Therefore, the numbers are 0.1, 1.2 and 17.4.

What is Intersecting line?When two or more lines intersect in a plane, they are referred to as intersecting lines. The intersecting lines share a common point, which exists on all of them and is known as the point of intersection.
What are the properties of intersecting lines?The intersecting lines (two or more) always meet at one point.
The intersecting lines may cross at any angle. This formed angle is always greater than 0° but less than 180°.
A pair of vertical angles is formed by two intersecting lines. Vertical angles are opposite angles that share a vertex (which is the point of intersection).

An object is moving at a speed of 3 kilometers every 5 days. Express this speed in yards per hour.
An object is moving at a speed of 27.3 yards per hour.
How to find the speed in yards?3 kilometers must first be converted to yards.
1 m = 1.09 yards.
1 Km = 1093.61
3 km to yards is 3280.84
Currently, we must convert 5 days to hours. There are 24 hours every day, we shall multiply that number by 5 to find the number of hours in 5 days.
5 * 24 = 120 hours
To determine the speed in yards per hour, divide 3280.84 by 120.

where d is the common difference
compare with
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 8

a large industrial firm purchases several new word processors at the end of each year, the exact num- ber depending on the frequency of repairs in the previ- ous year. suppose that the number of word processors, x, purchased each year has the following probability distribution:
This firm expects to spend on the new word processor expense of $1855 from the given probability distribution.
What is a probability distribution?
A random variable can have any number of alternative values and likelihoods within a particular range, and a probability distribution would be a statistical function that captures all of these possibilities. This range will be constrained by the minimum and maximum distinct combinations, but the location of the possible value on the probability distribution will rely on a number of other variables. These elements include the mean (median), and standard deviation, of the distribution.Given that the number of word processors, x, purchased each year has the probability distribution.
E(X)=1* (3/10)+2*(2/5)+3*(1/5)=1.7
E(X^2)=1^2(3/10)+2^2(2/5)+3^2(1/5)=3.7
Expense=E(1200x-50x^2)=E(1200x)+E(-50x^2)=1200E(x)-50E(x^2)
So
Expense=1200*1.7-50*3.7=1855
This firm expects to spend on the new word processor expense of $1855 from the given probability distribution.

A ball manufacturer wants to stack three balls, each with an 8-centimeter diameter, in a box that is an equilateral triangular prism. The diagram shows the dimensions of the bases. Will the balls fit in the box? Explain how you know.
Considering the volumes of the ball and of the box, it is found that the balls will not fit into the box.
Volume of the ballThe ball is spherical, with a diameter of 8 inches = radius of 4 inches.
The volume of an sphere of radius r is given by:
V = 4/3πr³.
Hence the volume of each ball is given by:
V = 4/3π x 4³ = 267.4 cm³.
The volume of the three balls is:
V = 3 x 267.4 cm³ = 802.2 cm³.
Volume of the boxThe box is a triangular prism, hence the volume is given by the multiplication of the base area by the height, as follows:
V = Ab x h.
The height of the box is of 9 cm, however we have to find the base area.
From the bisection, at the right side of the triangle, we have that half the side of the equilateral triangle is of 7.8 cm, hence the side length is of:
s = 2 x 7.8 = 15.6 cm.
Hence, bisecting the base triangle to find the height, it will have:
Height h. (side of a right triangle).Side of 7.8 cm (another side of a right triangle).Angle of 30º between them.Then the height can be found as follows:
tan(30º) = h/7.8 (tangent = opposite side/adjacent side)
h = 7.8 x tan(30º)
h = 4.5 cm.
The area of a triangle is half the multiplication of the side length and the height, hence the base area is:
A = 0.5 x 15.6 x 4.5 = 35.1 cm².
Then the volume of the box is:
V = 35.1 x 9 = 315.9 cm³.
The volume of the three balls is of 802.2 cm³ > 315.9 cm³, hence the three balls will not fit into the box.
What is the missing information?The box is missing and is given by the image at the end of the answer.

What does it mean by slope of a line ?
The ratio of the difference between the y- and x-coordinates of the two points that make up the line must be calculated. The slope of the line is the value that is obtained. It displays how the line's y-axis climb compares to its x-axis run.
Given : The two points are A( 0, 7 ) and B ( -8 , 0 )

General Equation:
a·x² + b·x + c = 0
a = 3;
b = 7;
c = - 6.
Discriminant:
D = b² - 4·a·c = 7² - 4·3·(-6) = 49 + 72 = 121

x₁ = ( - 7 - 11 ) / (2·3) = ( - 18) / 6 = -3
x₂ = ( - 7 + 11 ) / (2·3) = 4 / 6 = 2 / 3

it is 76 degrees at the 6000 foot level of a mountain and 49 degrees at the 12000 foot level of the mountain. write a linear equation to find the temperature T at an elevation x on the mountain, where x is in thousands of feet
The linear equation to find the temperature T at an elevation x on the mountain, where x is in thousands of feet will be T = (-9/2)x +103.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that, it is 76 degrees at the 6000-foot level of a mountain and 49 degrees at the 12000-foot level of the mountain.
As we know the linear equation in the slope-intercept is found as,
y =mx + b
Replace m with the c,y with the T, and b with the k as
T = cx + k
From the given data,
76 = c(6) + k
76 = 6c + k
⇒ k = 76 - 6c
For condition 2,
49 = c(12) + k
49 = 12c + k
Substitute the value of k in the above equation,
49 = 12c + (76 - 6c)
49 = 12c + 76 - 6c
49 - 76 = 6c
6c = -27
c=-9/2
Put the value of c in the equation,
K = 76 -6c
K = 76 -6(9/2)
K = 76+27
k = 103
Put the value of c and k in the equation below,
T = cx + k
T = (-9/2)x+103
Thus, the linear equation to find the temperature T at an elevation x on the mountain, where x is in thousands of feet will be T = (-9/2)x +103.
