Let the cost of petrol of the car be £ x
£x=580mile
33.5mile=1gallon
1gallon=4.55litre
1litre=£1.09
By using chain rule,
X x33.5x1x1=580x1x4.55x1.09
Or,x=85.86
So x=£85.86
26,130 that's how you write it in standard.
As we know,
Area of a circle= pi r.r
circumference of a circle= pi.d
so 6.25= pi.d
6.25= 2pi.r
r= 6.25/2pi= 0.99
so now
Area= pi.r.r = 3.14(0.99)(0.99) = 3.077 Answer.
Answer:
(-1/2,-5/2)
Step-by-step explanation:
x-y = 2
x+y = -3
---------------
Through Elimination, we can just add the system of equations. The y cancels out and gives us the single equation for x:
2x = -1
x = -1/2
Substitute -1/2 for x in either equation and you get:
(-1/2) + y = -3 Solve for y
y = -5/2

A man borrows * 8000
He agrees to repay with a total interest of 1360 in 12 monthly instalments.
Each instalment being less than the preceding one by * 40
