The capacity of Dr Khan's oil tank is 1,200 litres. There are currently 650 litres of oil in the tank.
Oil costs 77.2p per litre.
Dr Khan gets a 5% discount on the price of oil.
How much does it cost Dr Khan to fill the oil tank?

it costs = 40337p

Step-by-step explanation:

a) 1200 - 650 = 550L

b) 77.2p - 77.2 x0.05 = 73.34p per litre

c) the total money it costs to be filled the the oil tank by Dr Khan is 73.34 x 550L = 40337

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
