Richard, Allan, and Fliss share some money in the ratio 4: 8: 5.
Allan gets £9 more than Fliss.
Work out the amount of money that Richard gets.
Step-by-step explanation:
the ratio is 4:8:5 for Richard, Allan and Fliss.
the sequence is important.
the money pool between them has 4+8+5 = 17 equal units.
Richard has 4 units of these 17, Allan has 8 units, and Fliss has the remaining 5 units.
we don't know the value of such a unit yet.
this we get from the second hint :
Allan gets £9 more than Fliss.
remember, Allan has 8 units, Fliss 5.
so, Allan has 3 units more than Fliss.
that means these 3 units are worth £9.
and that means each unit is worth 9/3 = £3.
Richard has 4 units, that means he has

in rhombus $abcd$, points $e,f,g,$ and $h$ are the midpoints of $\overline{ab},\overline{bc},\overline{cd},$ and $\overline{da},$ respectively. quadrilateral $efgh$ has area 14 and perimeter 16. find the side length for rhombus $abcd$.
Side length of Rhombus ABCD is 8+2√2 unit
EFGH is a rectangle :
We know that ,
E, F , G , H are midpoints of AB, BC, CD , DA respectively
Since ABCD is a rhombus
AB = BC = CD = DA
AB ll CD and BC ll DA
since, E, F , G , H are midpoints of AB, BC, CD , DA respectively
from the figure below we can say that ,
1) AB ll CD ll FH and AB= CD = FH
2) BC ll DA ll GE and BC = DA = GE
Using mid point theorem we can say that ,
GH = EF = 1/2 AC and FG= EH = 1/2 BD
Since for the figure EFGH opposite sides are equal and and parallel , and the diagonals are equal in length we can say that EFGH is a rectangle.
Perimeter of a rectangle = 2(a+b) = 2( GH + EH ) = 2 (EF + GF) = 2 ( 1/2 AC + 1/2 BD )
= 2 x 1/2 ( AC + BD ) = 16
⇒ AC + BD = 16 (1)
now area of a rectangle is given by
A = ab = GH x EH = EF x GF = 1/2 AC x 1/2 BD = 1/4 (AC x BD) = 14
⇒AC x BD = 14 x 4 = 56
from equation (1)
AC ( 16 - AC) = 56
= 16 AC - AC ^2 = 56
⇒ AC^2 - 16 AC + 56 = 0
AC = 8 +/- 2√2
BD = ( 16 - AC) = 8 +/- 2 √2 = side length of rhombus ABCD

Identify an equation in point slope form for the perpindicular to y=-3x+5 that passes through (4,-1)
Answer:
[tex]\boxed {y = \dfrac{1}{3}x - \dfrac{7}{3}}[/tex]
Step-by-step explanation:
If we have a line y = mx + b where m is the slope and be is the y-intercept then a line perpendicular to this line will have slope -(1/m)
So the slope of the line perpendicular to y = -3x + 5 will be [tex]-\dfrac{1}{3}[/tex] = + 1/3 = 1/3
So the perpendicular line equation is
y = (1/3)x + b where b is the y intercept of this line
Since it passes through the point x = 4, y = -1 we plug in these values for x and y and solve for b
We get
[tex]-1=\dfrac{1}{3}\cdot \:4+b[/tex]
Switch sides
[tex]\dfrac{1}{3}\cdot \:4+b=-1[/tex]
[tex]\dfrac{4}{3}+b=-1[/tex]
Subtract [tex]\dfrac{4}{3}[/tex] from both sides
[tex]b = -1 - \dfrac{4}{3} = -\dfrac{3}{3} -\dfrac{4}{3} = -\dfrac{7}{3}[/tex]
So the equation of the perpendicular line is
[tex]\boxed {y = \dfrac{1}{3}x - \dfrac{7}{3}}[/tex]

the height of the cone to the nearest tenth of a centimetre?
Answer:
64.5cmStep-by-step explanation:
I hope this answer help you
Answer:
h = 16.0 cm
Step-by-step explanation:
Note: I am assuming that the surface area of 258 is the total surface area which includes the Lateral Area (L) and Base Area(B)
Total Surface Area of a right cone
= Lateral Area(L) + Base Area(B)
All numbers in intermediate calculations are rounded to tenth of centimeter i.e. 1 decimal point
Base Area is the area of the circle with radius 4 = [tex]\displaystyle \pi \cdot16 = 50.3[/tex] cm²
Total Area = 258 cm²
So Lateral Area = 258 - 50.3 = 207.7 cm²
Lateral Area is given by the formula
[tex]\displaystyle L = \pi r s \textrm{ where s is the slant height }[/tex]
So we get
[tex]\displaystyle \rm pi \cdot 4 \cdot s = 207.7\\\\\textrm {This gives } s = \dfrac{207.7}{4\pi} = 16.5\\\\[/tex] cm
Slant height is given by the formula:
[tex]s = \sqrt{r^2 + h^2} \textrm{ where r is the radius and h the height}[/tex]
Plugging in values we get
[tex]16.5 = \sqrt{4^2 + h^2} = \sqrt{16 + h^2}[/tex]
Square both sides
[tex]16.5^2 = 16 + h^2[/tex]
==> [tex]h^2 = 16.5^2 - 16 = 256.25\\\\h = \sqrt{256.25} = 16.003 = 16.0[/tex] rounded to 1 decimal place

The perimeter is 26. How much bigger is the longest side than the shortest side?
Answer:
8
Step-by-step explanation:
the perimeter is the sum of the 3 sides of the triangle.
Given perimeter = 26 , then
2a - 3 + 2a + 3a + 1 = 26 , that is
7a - 2 = 26 ( add 2 to both sides )
7a = 28 ( divide both sides by 7 )
a = 4
then
shortest side = 2a - 3 = 2(4) - 3 = 8 - 3 = 5
longest side = 3a + 1 = 3(4) + 1 = 12 + 1 = 13
the difference between the 2 sides is 13 - 5 = 8
the longer side is 8 units bigger than the shortest side

When p = 0.125 the equation -3p + ( 1/8 ) = ( - 1/4 ) is true.
The given equation is:
-3p + ( 1/8 ) = ( - 1/4 )
On the left-hand side of the equation, the denominator of the two terms is not the same.
So, the LCM of 1 and 8 is 8.
Therefore,
- 3p × ( 8 / 8 ) + ( 1 / 8 ) × ( 1 / 1 ) = ( - 1 /4 )
- 24p / 8 + 1 / 8 = - 1 / 4
( - 24p + 1 ) / 8 = - 1 / 4
Now multiplying each side of the equation by 8.
We get,
[ ( - 24p + 1 ) / 8 ] × 8 = ( - 1 / 4 ) × 8
- 24p + 1 = - 8 / 4
- 24p + 1 = - 2
Subtracting 1 from each side of the equation,
- 24p + 1 - 1 = - 2 - 1
-24p = - 3
Now, divide each side of the equation by 24.
- 24p / 24 = - 3 / 24
- p = ( - 1 / 8 )
Multiplying by - 1 on each side of the equation,
( - p ) × ( - 1 ) = ( - 1 / 8 ) × ( - 1 )
p = 1 / 8
p = 0.125

We know that when two lines intersect then the vertically opposite angles are equal.
So according to the given figure
(11x + 47)° = (6x + 77)°
Solving the above equation for x we get
11x° + 47° = 6x° + 77°
5x° = 30°
x = 6°
Thus the value of x is 6°
Also note that the linear pair of angles make 180°. That is sum of the two angle is 180°. As we can see from the figure ∠z and (6x + 77)° make linear pair of angles, therefore there sum will be equal to 180°.
Thus, ∠z + (6x + 77)° = 180°
∠z + (6*6 + 77)° = 180°

The probability of getting a number 6 as the first card and a queen as the second card is 4/663.
Probability is mathematically defined as the ratio of the number of outcomes of a particular event or occurrence to the total number of outcomes.
For a standard deck, there are 52 total outcomes since there are 52 cards. A standard deck is divided into four suits - hearts, clubs, spades, and diamonds - with 13 cards each. Each suit has nine numbered cards from 2 to 10, three face cards (king, queen, and jack), and an ace.
The probability of having a numbered 6 card is 4/52. The probability is the same for getting a queen. Although, the probability of getting 6 as the first card and the queen as the second is different. This kind of probability requires the multiplication rule.
First card probability = 4/52
Second card probability = 4/51
The total number of outcomes for the second card is reduced since the first card is not replaced.
