Answer:
Phoebe has £180, Andy has £60, and Polly has £30.
Step-by-step explanation:
Ok, to start of let's establish some variables! We'll give Phoebe the variable "p", Andy the variable "a", and Polly the variable "o". By giving each person a variable we can create an equation and solve for it!
So, what do we know?
Well we know the following information...
p + a + o = 270
(Phoebe + Andy + Polly = £270)
p = 3a
(Phoebe = 3 times more than Andy)
a = 2o
(Andy = 2 times more than Polly)
To be able to solve this equation we have to solve for just one variable first.The only one we can use is "o" for Polly!
3(2o) + 2o + o = 270
6o + 2o + o = 270 (Distribute 3 to get like terms)
9o = 270 (Combine like terms [6+2+1])
o = 30 (Divide by 9 on both sides to get "o" by itself)
Now that we have how much Polly has, we have to solve for Andy and Phoebe. (To do this we will input our value, 30, where our variable is "o")
Andy
a = 2(30) (Input term)
a = 60 (Multiply by 2 to get final answer)
(Since we now know what Andy has we can input 60 into our "a" variable to solve for Phoebe)
Phoebe
p = 3(60) (Input term)
p = 180 (Multiply by 3 to get final answer)
Now! Just to check we are going to input our variables into our original equation to be sure we have the right variables.
p + a + o = 270
180 + 60 + 30 = 270!!
Hope this Helps! :)

Mrs. Thomas has two rolls of garden edging that are each 96 inches long.
She wants to make two new flower beds in her back yard. Each flower bed
will be bordered by one roll of the edging. One flower bed will be in the
shape of a quadrilateral. The other will be in the shape of a triangle.
Please answer all parts. I will give brainliest for correct answer!
Answer:
A) The total length of each edging in her scale drawing would be 19.2 centimeters.
B) Square or rectangle
C) angle α= 53.13 degrees
angle β= 36.87 degrees
height= 32 inches
base= 24 inches
hypotenuse 40 inches.
Step-by-step explanation:
Part A:
If the roll edging is 96 inches long and the scale chosen is
5inches = 1 cm
96inches /5= 19.2cm
The total length of each edging in her scale drawing would be 19.2 centimeters.
Part B:
The quadrilaterals such rectangle square right trapezoid have a pair of 90 degrees angles.
If we choose a square shape then all sides must be equal. And we have a length of 19.2 centimeters.
Dividing 19.2 by 4 gives 4.8 cm for each side.
Figure A shows a square and has 4 sides equal and 4 right angles.
If we choose a rectangle shape then 2 sides must be equal. We have a length of 19.2 centimeters.
Suppose the length is 2 times more than the width
which will give the dimensions as
2*2 x+ 2x= 6x ( length and width denoted by x)
Dividing 19.2 by 6 gives 3.2 cm for each width and 6.4 for the lengths.
Figure B shows a rectangle and has 2 sides equal and 4 right angles.
It depends on which quadrilateral you wish to choose.
Part C:
Using Pythagorus theorem if the base and altitude are given then the hypotenuse can be found out using the following formula.
c²= a² +b²
c²= 6.4² +4.8²
c²= 40.96+23.04= 64
c= √64 = 8
The third side must be equal to 8 centimeters.
Using the formula
Cos α= base / hypotenuse
Cos α=4.8/8
α= Cos (inverse) 4.8/8
α= Cos (inverse) 0.6
α= 53.13 degrees
So angle α= 53.13 degrees
All the angles in the triangle must be 180 degrees.
α + β + 90°= 180°
And angle β= 180-90-53.13= 36.869= 36.87 degrees
The actual dimensions of this triangle are
height= a= 6.4* 5= 32 inches
base= b= 4.8*5= 24 inches
hypotenuse= 8*5= 40 inches.

Answer: £30.31
Explanation:
100/140 minutes of calls were free. Then, 40 x .09, which is 3.6

john drew rhombus RSTV. He drew both diagonals that intersect at point M. in johns figure, which would be the measure of RMS
-45°
-90°
-180°
-360°
Answer:
Option B
Step-by-step explanation:
One of the basic property of Rhombus is that its diagonal intersect each other in a way that they bisect each other and also make angle of 90 degrees
Angle RMS comprises of angle formed by the bisecting diagonals. Hence angle RMS is of 90 degrees.
Thus, option B is correct

Triangle Review 2.0 (Math i need help please)
Answer:
A= 30
Step-by-step explanation:
This requires several steps.
First, you need to find the 2 other missing angles.
One can be found easily by substracting 130 from 180
so 180-130 = 50
The other angle is the same as 8x+4
Now set up your equation
180=3x-6 + 8x+4 +50
180 = 3x + 8x -6 + 4 +50
180+6-4-50 = 11x
132 = 11x
132/11 = x
12 = x
Now plug in 12 for x in your angle A
A=3x-6
A=3 * 12 - 6
A=36 - 6
A= 30

The equation of proportion is y equals 2 over 9 x and , y = ( 2/9 )x
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the value of A is
where y varies directly with x, and y is 16 when x is 72
So , when x = 72 , y = 16
y = kx
16 = k ( 72 )
Divide by 72 on both sides , we get
k = 16 / 72
k = 2/9
Therefore , the value of A is y = ( 2/9 )x
Hence , the equation is y = ( 2/9 )x
