Answer:
Perpendicular bisector theorem
Step-by-step explanation:
The illustration of the theorem is:
If point B is a perpendicular bisector of Line AC and the length of AC is 10cm
Then

Where
--- Perpendicular bisector
So, the equation becomes



Recall: 

The total amount of money they collected for the charity is 29.1 pounds
<h3>How to find the total amount they collected?</h3>
100 pence = 1 pounds
Hence,
52 twenty pence coins = 1040 pence = 1040 / 100 = 10.4 pounds
59 ten pence coins = 590 pence = 590 / 100 = 5.9 pounds
26 five pence coins = 130 pence = 1.3 pounds
5 fifty pence coins = 250 pence = 2.5 pounds
9 £1 coins = 9 pounds
Therefore,
The amount of money collected = 10.4 + 5.9 + 1.3 + 2.5 + 9 = 29.1 pounds

Answer:
expression: y = 3.6x
for x = 11, then y = 39.6
Step-by-step explanation:
Direct variation uses the following equation:
y = kx
For each case, there will be an actual number instead of k.
We need to find which value of k our problem uses. We can use teh given x and y values, and solve for k.
y = kx, use x = 5 and y = 18, and solve for k
18 = k * 5
k = 18/5 = 3.6
In our case, k = 3.6, so the specific equation for direct varuiation for this problem is
y = 3.6x
Now we can find y when x = 11.
y = 3.6x
y = 3.6(11)
y = 39.6
