Answer:
£40.
Step-by-step explanation:
In terms of ratio units, Stephen and Bridget together get 3+2 = 5, while Paul receives 4. That is, Paul gets 4/5 of their combined total, or ...
4/5 · £50 = £40
Paul gets £40.
Given parameters:
Ratio of their money = 3 : 4 : 2
Total amount received by Stephen and Bridget = 50
Unknown :
How much did Paul get = ?
Solution:
The amount Paul got is a fraction of the total.
We need to find the total amount first;
Amount Stephen and Bridget got = [tex]\frac{ratio of stephen and bridget}{total ratio} x total amount[/tex]
let the total amount = y;
50 = [tex]\frac{3+2}{9}[/tex] x y
[tex]\frac{5y}{9}[/tex] = 50
5y = 450
y = 90
Now, the amount Paul got;
= [tex]\frac{4}{9} x 90[/tex]
= 40
The amount Paul got is £40
[tex] \tan(x) [/tex]

PLEASE HELP!!!! Which quadratic equation is part of the solution process for solving this rational equation using the least common denominator?
Answer: for plato users
A is the correct answer
Step-by-step explanation:
I just took the test had 100%
The correct option is A. [tex]x^{2} -x-10=0[/tex].
Given quadratic equation [tex]\frac{2}{3x-6} -\frac{1}{3x+6} =\frac{1}{3}[/tex]
On solving, [tex]\frac{2(3x+6)-1(3x-6)}{(3x-6)(3x+6)} =\frac{1}{3}[/tex]
Further, [tex]\frac{6x+12-3x+6}{9x^{2} -6^{2} } =\frac{1}{3}[/tex]
[tex]\frac{3x+18}{9x^{2} -36} =\frac{1}{3}[/tex]
Taking 3 common from numerator and 9 common from denominator, we have
[tex]\frac{3(x+6)}{9(x^{2} -4)} =\frac{1}{3}[/tex]
[tex]\frac{(x+6)}{3(x^{2} -4)} =\frac{1}{3}[/tex]
[tex]\frac{x+6}{x^{2} -4} =1[/tex]
[tex]x+6=x^{2} -4[/tex]
On rearranging in decreasing powers of x we get,[tex]x^{2} -x-10=0[/tex].
Hence on solving, We get [tex]x^{2} -x-10=0.[/tex]

Answer:
AC = 16.5
AE = 9
Step-by-step explanation:
Connect AC and BE
Note m∠ACD = m∠ACB, (both face arc BD)
ΔACD ~ ΔABE
AD : AB = AC : AE
6 : 4 = AC : (6 + 5)
3 : 2 = AC : 11
2AC = 3*11 = 33
AC = 16.5

Answer:
y=1/3x +16/3
Step-by-step explanation:
m=(y2-y1) / (x2-x1)
=(6-5) (2- -1)
=1/3
Substitute in m and either point into the point slope form
y=m(x-x1) + y
y=1/3(x- -1) +5
y=1/3(x+1) +5
Now lets distribute the 1/3 to and combine the constants to put the answer in standard form
y=1/3x + 1/3 + 5
y=1/3x +1/3 + 15/3
y=1/3x +16/3

Step-by-step explanation:
The smaller of the two containers has a capacity of 150 gallons. When it is $\frac{4}{5}$ full, its contents are emptied into a larger container, filling exactly $\frac{2}{3}$ of it. What is the capacity, in gallons of the larger container?
Answer:
180 gallons
Step-by-step explanation:
The smaller container has 150 gallons.
Now the large container is filled with the 4/5 of the smaller container.
So if the full volume of the small container is 150 gallons so the 4/5 of it can be calculated as, 4/5*150=120 gallons.

12. The thickness of a plywood is 11 mm.
(i) How many centimetres is this?
(ii) what part of a metre is mm
Answer:
I) 1.1cm
II) 0.001m = 1mm
Step-by-step explanation:
I)
10mm = 1 cm
11mm = ?
? = (11 x 1)/10 =11/10 =1.1
II)
1000mm = 1m
Milli represents 10^-3 = 0.001
1 millimeter = 1 x 0.001 =0.001m
The area in square feet of a rectangular field is
x2 – 120x + 3500. The width, in feet, is x-50. What is the
length, in feet?
Answer:
Length in feet: x-70
Step-by-step explanation:
Use factorization to find the length
Area = X^2-120x+3500
Area= length x width.
Area= L x (x-50)= (x-___) (x-50)
To find L we know that in factoring the quadratic equation 50 x __ must be equal to 3500.
(x-70)(x-50) = x^2-120x+3500.
4) The length of a rectangle is double its width. Its perimeter is 33cm. How long is its
width?
5.5 cm
Step-by-step explanation:
Let x be the width of the rectangle.
Since the length is double the width, the length would be 2x.
x can be found by solving the perimeter equation. The perimeter of the rectangle can be found by the equation:
[tex]p = 2(l + w)[/tex]
[tex]33 = 2(2x + x)[/tex]
[tex]33 \div 2 = (2x + x)[/tex]
[tex]16.5 = 3x[/tex]
[tex]16.5 \div 3 = x[/tex]
[tex]5.5 = x[/tex]
Therefore, the width of the rectangle is 5.5 cm.
