Answer:
£290.70
Step-by-step explanation:
Number of notes of $50 = 5
Total value = 50 × 5 = $250
Number of notes of $20 = 2
Total value = 20 × 2 = $40
Number of notes of $10 = 7
Total value = 10 × 7 = $70
Number of notes of $5 = 3
Total value = 5 × 3 = $15
Total value of all notes with John = 250 + 40 + 70 + 15
= $375
Since, $1.29 = £1
Therefore, $1 = £
Therefore, $375 = £ 
= £290.70
Answer:
The Prime Factorization of 80 is, 2 × 4 × 10, 2 × 2 × 2 × 2 × 5 and 2 × 4 × 10
Step-by-step explanation: They are correct, because they all equal 80. 2 × 4 × 10=80 and 2 × 4 × 10=80, and 2 × 2 × 2 × 2 × 5=80.
24 × 5=120, Therefore it's the only incorrect question.

Answer:
Step-by-step explanation:
Given
---- the perimeter of fencing
Required
The maximum area
Let
So, we have:
This gives:
Divide by 2
Make L the subject
The area (A) of the fence is:
Substitute
Open bracket
Differentiate with respect to W
Set to 0
Solve for 2W
Solve for W
Recall that:
So, the maximum area is:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero
m= 5x-2016
